Your new Sullair flood-lubricated rotary screw air compressor will provide you with a unique experience in improved reliability and simplified maintenance. Read Section 6, MAINTENANCE to see how surprisingly easy it is to keep your air compressor in top operating condition. Figure 2-1                   3!? 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. Fluid Filter Moisture Separator Sump Tank Fluid Fill Sight Glass Fluid Fill Starter Box Controller E-Stop Button Compressor Unit Cooler Fan Motor Cooler Motor Air Inlet Filter Figure 2-1 Overall Component Layout - Air-Cooled Model ® SULLAIR ® 3700 Operator’s Manual and Parts List 7 SECTION 2 2.2 DESCRIPTION OF COMPONENTS Refer to Figure 2-1 and Figure 2-2. The components and assemblies of the air compressor are clearly shown. The complete package includes compressor, electric motor, starter, compressor inlet system, compressor discharge system, compressor lubrication and cooling system, capacity control system, microprocessor controller, aftercooler, a combination separator and trap, all mounted on a heavy gauge steel frame. On air-cooled models, a fan draws air into the enclosure over the fan and main motors through the combined aftercooler and fluid cooler thereby removing the compression heat from the compressed air and the cooling fluid, and forces it out the top of the machine. On water-cooled models, a shell and tube heat exchanger is mounted on the compressor frame. Fluid is piped into the heat exchanger where compression heat is removed from the fluid. Another similar heat exchanger cools the compressed air. Both air-cooled and water-cooled versions have easily accessible items such as the fluid filter air/oil separator and control valves. The inlet air filter is also easily accessible for servicing. Sullair recommends that a 24KT sample be taken at the first filter change and sent to the factory for analysis. This is a free service. The sample kit with instructions and self-addressed container is to be supplied by your Sullair dealer at start-up. The user will receive an analysis report with recommendations. Fluid is injected into the compressor unit hoses and mixes directly with the air as the rotors turn, compressing the air. The fluid flow has three basic functions: 1. As coolant, it controls the rise of air temperature normally associated with the heat of compression. 2. Seals the clearance paths between the rotors and the stator and also between the rotors themselves. 3. Acts as a lubricating film between the rotors allowing one rotor to directly drive the other, which is an idler. After the air/fluid mixture is discharged from the compressor unit, the fluid is separated from the air. At this time, the air flows through an aftercooler and separator then to your service line while the fluid is being cooled in preparation for reinjection. 2.3 SULLAIR COMPRESSOR UNIT, FUNCTIONAL DESCRIPTION Sullair air compressors feature the Sullair compressor unit, a single-stage, positive displacement, flood lubricated-type compressor. This unit provides continuous compression to meet your needs. NOTE With a Sullair compressor, there is no maintenance or inspection of the internal parts of the compressor unit permitted in accordance with the terms of the warranty. SU_0000021 The 3700 Series compressors are factory-filled with Sullube lubricant. For more information on fluid fill, consult Section 3, SPECIFICATIONS. Sullair 24KT compressors are filled with a fluid that rarely needs to be changed. Use only Sullair 24KT fluid in the event that a fluid change is required. CAUTION Mixing of other lubricants within the compressor unit will void all warranties. SU-0000022 8 3700 Operator’s Manual and Parts List ® SULLAIR ® DESCRIPTION Figure 2-2 COOLING / LUBRICATION SYSTEM DISCHARGE SYSTEM SA_0000009 Figure 2-2 Air-Cooled Cooling/Lubrication and Discharge System ® SULLAIR ® 3700 Operator’s Manual and Parts List 9 SECTION 2 2.4 COMPRESSOR COOLING AND LUBRICATION SYSTEM, FUNCTIONAL DESCRIPTION Refer to Figure 2-2. The Cooling and Lubrication System (air-cooled version) consists of a fan, fan motor, radiator-type aftercooler/fluid cooler, full flow fluid filter, thermal valve, and interconnecting hoses. For water-cooled models, two shell and tube heat exchangers and a water-flow regulating valve are substituted for the radiator-type cooler listed above. The pressure in the receiver/sump causes fluid flow by forcing the fluid from the high pressure area of the sump to an area of lower pressure in the compressor unit. Fluid flows from the bottom of the receiver/sump to the thermal valve. The thermal valve is fully open when the fluid temperature is below 185°F (85°C) [200°F (93°C) for 24KT] and pressures are rated at or above 150 psig. The fluid passes through the thermal valve, the main filter and directly to the compressor unit where it lubricates, cools and seals the rotors and the compression chamber. As the discharge temperature rises above 185°F (85°C), due to the heat of compression, the thermal valve begins to close and a portion of the fluid then flows through the cooler. From the cooler the fluid flows to the fluid filter and then on to the compressor unit. A portion of the fluid flowing to the compressor is routed to the anti-friction bearings which support the rotors inside the compressor unit. The fluid filter has a replacement element and an integral pressure bypass valve. A message on the controller indicates when the fluid filter needs to be changed. Water-cooled models have a water pressure switch to prevent operation with inadequate water pressure. 2.5 COMPRESSOR DISCHARGE SYSTEM, FUNCTIONAL DESCRIPTION Refer to Figure 2-2. The compressor unit discharges the compressed air/fluid mixture into the combination receiver/sump. The receiver has three basic functions: 1. It acts as a primary fluid separator. 2. Serves as the compressor fluid sump. 3. Houses the final fluid separator. 10 The compressed air/fluid mixture enters the receiver and flows through an internal baffle system. The direction of movement is changed and its velocity significantly reduced, thus causing large droplets of fluid to form and fall to the bottom of the receiver/sump. The fractional percentage of fluid remaining in the compressed air collects on the surface of the separator element as the compressed air flows through the separator. A return line (or scavenge tube) leads from the bottom of the separator element to a medium pressure region of the compressor unit. Fluid collecting on the bottom of the separator is returned to the compressor by a pressure differential between the receiver and the compressor. A visual sight glass is located on the return line to observe this fluid flow. There is also an orifice in this return line (protected by a strainer) to assure proper flow. The separator system reduces the fluid carry-over to less than 1 ppm (parts per million) or 2 ppm for 24KT. A message on the controller indicates if abnormal pressure drop through the separator develops. At this time, separator element replacement is necessary. A minimum pressure/check valve, located downstream from the separator, assures a minimum receiver pressure of 50 psig (3.4 bar) during loaded conditions. This pressure is necessary for proper air/fluid separation and proper fluid circulation. A terminal check valve is incorporated into the minimum pressure/check valve to prevent compressed air in the service line from bleeding back into the receiver on shutdown and during operation of the compressor in an unloaded condition. A pressure relief valve (located on the wet side of the separator) is set to open if the sump pressure exceeds the sump tank rating. A temperature switch will shut down the compressor if the discharge temperature reaches 235°F (113°C). A WARNING DO NOT remove caps, plugs, and/or other components when compressor is running or pressurized. Stop compressor and relieve all internal pressure before doing so. SU_0000023 Fluid is added to the sump via a capped fluid filler opening, placed low on the tank to prevent overfilling of the sump. A sight glass enables the operator to visually monitor the sump fluid level. 3700 Operator’s Manual and Parts List ® SULLAIR ® DESCRIPTION 2.6 CONTROL SYSTEM, FUNCTIONAL DESCRIPTION START MODE - 0 TO 50 PSIG (0 TO 3.5 BAR) Refer to Figure 2-3. The purpose of the compressor Control System is to regulate the amount of air being compressed to match the amount of compressed air being used. The Capacity Control System consists of a solenoid valve, regulator valve and an inlet valve. The functional description of the Control System is described below in four distinct phases of operation. For explanatory purposes, this description will apply to a compressor with an operating range of 100 to 110 psig (6.9 to 7.6 bar). A compressor with any other pressure range would operate in the same manner except stated pressures. When the compressor “ ” (START) pad is depressed, the sump pressure will quickly rise from 0 to 50 psig (0 3.4 bar). The compressor initially starts unloaded with solenoid valve open and inlet valve closed. It then switches to full load when full rpm has been achieved. During this period, both the pressure regulator and the solenoid valve are closed, the inlet valve is fully open and the compressor pumps at full rated capacity. The rising compressor air pressure is isolated from the service line in this phase by the minimum pressure valve set at approximately 50 psig (3.4 bar).

Air Outlet Pressure Regulator Solenoid Valve Air Inlet Blowdown Valve Minimum Pressure / Check Valve Sump Tank Figure 2-4 Sequencing Control System FULL LOAD MODE - 50 TO 100 PSIG (3.4 TO 6.9 BAR) MODULATING MODE - 100 TO 110 PSIG (6.9 TO 7.6 BAR) When the compressed air pressure rises above 50 psig (3.4 bar), the minimum pressure valve opens allowing compressed air to flow into the service line. From this point on, the line air pressure is continually monitored by the microprocessor controller. The pressure regulator and the solenoid valve remain closed during this phase. The inlet valve is in the fully open position as long as the compressor is running at 100 psig (6.9 bar) or below. If less than the rated capacity of compressed air is being used, the service line pressure will rise above 100 psig (6.9 bar). The pressure regulator valve gradually opens, directing air pressure to the inlet control valve, reducing air entering the compressor until it matches the amount of air being used. The control system functions continually in this manner between the limits of 100 to 110 psig (6.9 to 7.6 bar) in response to varying demands from the service line. 12 3700 Operator’s Manual and Parts List ® SULLAIR ® DESCRIPTION The integrated inlet valve has an orifice which vents a small amount of air inlet when the pressure regulator controls the inlet control valve. The orifice also bleeds any accumulated moisture from the control lines. UNLOAD MODE - IN EXCESS OF 110 PSIG (7.6 BAR) When a relatively small amount or no air is being used, the service line pressure continues to rise. When it exceeds 110 psig (7.6 bar), the microprocessor control system de-energizes the solenoid valve allowing sump air pressure to be supplied directly to close the inlet valve. Simultaneously, the solenoid valve sends a pneumatic signal to the blowdown valve. The blowdown valve opens to the atmosphere, located in the compressor intake, reducing the sump pressure to approximately 17 psig (1.2 bar). The check valve in the air service line prevents line pressure from returning to the sump. When the line pressure drops to the low setting (cut-in pressure; usually 100 psig (6.9 bar) on low pressure (7 bar) compressors and 125 psig (8.6 bar) on high pressure (9 bar) compressors, 150 psig (10.3 bar) on (10 bar) compressors, 175 psig (12.0 bar) (12 bar), the microprocessor controller energizes the solenoid valve and allows the blowdown valve to close. The reenergized solenoid valve again prevents line pressure from reaching the inlet control valve. Should the pressure begin to rise, the pressure regulator will resume its normal function as previously described. LOAD/NO LOAD CONTROL 2.7 AIR INLET SYSTEM, FUNCTIONAL DESCRIPTION Refer to Figure 2-5. The Compressor Inlet System consists of a dry-type air filter, a restriction gauge and an air inlet valve. The restriction gauge (located on the air filter) indicates the condition of the air filter by showing red when filter maintenance is required. The poppet-type modulating air inlet valve directly controls the amount of air intake to the compressor in response to the operation of the pressure regulator (see MODULATING MODE - 100 TO 110 PSIG (6.9 TO 7.6 BAR) on page 12). The inlet valve also acts as a check valve, thus preventing reverse rotation when the compressor is shut down. A WARNING “The Plastic Pipe Institute recommends against the use of thermoplastic pipe to transport compressed air or other compressed gases in exposed above ground locations, e.g. in exposed plant piping.” (I) Sullube should not be used with PVC piping systems. It may affect the bond at cemented joints. Certain other plastic materials may also be affected. (I) Plastic Pipe Institute, Recommendation B, Adopted January 19, 1972. SU_0000024 If desired by the customer, the compressor can be set to operate load/no load without modulating control. This control mode is often selected when a large amount of compressed air storage (air tank) is available. Using the microprocessor keypad, select “load/no load control” from the menu. On a machine rated for 100 psig (7 bar) the compressor will run in the full load mode up to 100 psig (7 bar). If less than the rated capacity is required, pressure will rise above 100 psig and the microprocessor will de-energize the solenoid valve, causing the compressor to run in the unload mode. When the system pressure falls to 90 psig (6.3 bar), the microprocessor energizes the solenoid valve, causing the compressor to return to the full load mode. The compressor will thus operate to keep the system pressure in the range of 90-100 psig (6.3 - 6.9 bar). AUTOMATIC OPERATION For applications with varied periods of time when there are no air requirements, the microprocessor’s AUTOMATIC mode allows the compressor to shutdown (time delayed) when no compressed air requirement is present and restart as compressed air is needed. ® SULLAIR ® 3700 Operator’s Manual and Parts List 13 SECTION 2 Figure 2-5     3!? 1. 2.

It should be rigid enough to keep the compressor frame level and maintain alignment of the compressor and motor. Tiedown bolts of sufficient size must be used to provide uniform contact between the foundation and the compressor frame. Materials such as rubber or cork can be used to provide uniform contact between the foundation and compressor frame. AIR-COOLED COMPRESSORS • Piping loads must be eliminated through the use of flex connectors or other systems which prevent piping loads from being transmitted to the compressor. • Special consideration should be made to meet national and local electrical codes for the required space around and in front of the electrical panel. Lighting should be provided for future service requirements. • Accessibility for fork lift trucks, overhead cranes and maintenance vehicles should be given careful consideration in order to provide any maintenance that may be required. Adequate space around the unit should be provided for access to all components of the compressor. • Softer surfaces in walls or ceilings will absorb sound and minimize ambient noise levels. Harder, reflective surfaces will increase ambient noise levels. • An area with adequate space must be provided for the compressor and its components. Air-cooled compressors require a minimum of 3 feet (1 meter) around the perimeter of the compressor. • The location should be free from standing water and allow access to clean air that is free from exhaust and paint fumes, dust, metal filings or caustic chemicals. • Cooling air should be removed from the area in order to prevent the re-introduction of heated exhaust air back into the compressor’s cooling system. • Reduced headroom above the compressor will require that cooling air be either ducted or in some way deflected away from the compressor. Inadequate ventilation will result in higher ambient operating temperatures. NOTE Systems that employ both a conventional reciprocating compressor and a screwtype axial compressor must be isolated from each other by use of a common receiver tank. Individual airlines from each compressor should be piped to the common receiver tank. SU_0000027 • Water-cooled compressors must have provisions for cooling water supply and drainage available. NOTE NOTE Ambient temperatures above 104°F (40°C) require that the high ambient option is specified for the compressor. Shipping straps are painted red in order to help identify them for removal. Be sure to remove them prior to operation of the drive assembly. SU_0000028 SU_0000026 ® SULLAIR ® 3700 Operator’s Manual and Parts List 25 SECTION 4 OUTDOOR INSTALLATION (SHELTERED) Many times a compressor must be installed outside due to available space or other jobsite conditions. When this is necessary, there are certain items that should be incorporated into the system to help ensure trouble-free operation. The unit must be purchased with a TEFC motor. The standard machine has NEMA4 rated controls, which are watertight. NOTE Discharged air contains a very small amount of compressor lubricating oil, and care should be taken to ensure that this oil would not interfere with downstream equipment. An air dryer can remove any liquid carryover. SU_0000030 PIPE SIZING NOTE Variable speed drive compressors are NEMA 12 rated and must not be installed outside or exposed to the elements. SU_0000041 Pipe should be sized at least as large as the discharge connection of the compressor. Piping and fittings should all be suitably rated for the discharge pressure. USE OF AUXILIARY RECEIVER / SUMP The compressor should be on a concrete pad, which is designed to drain water away from it. If the concrete pad is sloped, then the compressor must be mounted so that it is level. The base or skid must be sealed where it contacts the concrete pad. An auxiliary receiver/sump should be used in cases where large demand swings are expected. This is not necessary with a variable speed design. A weatherhood option should be selected to prevent direct rain and snow from falling on the unit. If local weather conditions can be extreme such that direct rain or snow may fall on the unit, it should be in a fully enclosed room or building. If isolation of the compressor from the service lines is required, isolation valves should be installed close to the discharge of the compressor. They should be installed with drip legs that drain sloping downward from the base in order to drain properly. Install a vent to the piping downstream of the minimum pressure check valve on the separator tank, and upstream of the first isolation valve. If installed under a shelter, air-cooled machines must be positioned in a way that prevents air recirculation (i.e., hot exhaust being allowed back to the system air inlet). In installations that include more than one compressor, hot air exhaust should not be directed toward the fresh air intake of the second unit or an air dryer. A standard machine installed outside must not be started or run if the ambient temperature in and around the compressor drops or may drop below 35°F (1.7°C). For installation in a below freezing climate, a low ambient option with heat tracing and a sump heater must be installed. ISOLATION VALVE(S) When two compressors are operated in parallel, provide an isolation valve and a drain trap for each compressor before the common receiver. A built-in after-cooler reduces the discharge air temperature below the dew point. For most ambient conditions, considerable water vapor is condensed. To remove the condensation, each compressor with built-in after-cooler is supplied with a combination condensate separator/trap. A drain line should be installed on the condensate drain. 4.3 SERVICE AIR PIPING Review carefully the total air system before installing a new compressor. Items to consider for the total air system include liquid carryover, pipe sizing, and the use of an auxiliary receiver. The installation of a drip leg or multiple drip legs, installation of a line filter(s) and the installation of isolation valve or valves. These considerations are important to ensure a safe and effective system. 26 3700 Operator’s Manual and Parts List ® SULLAIR ® INSTALLATION FLUID CONTAINMENT 4.6 ELECTRICAL PREPARATION Compressors are equipped with a fluid containment pan to catch any fluid in the event of a leak or spill. The drain for the pan is located on the air intake end of the machine. For indoor installations, the drain should be plugged to contain fluids. For outdoor applications, the drain must be connected to a separate, customer supplied system to allow rainwater or any accumulated compressor fluid to drain out. Interior electrical wiring is performed at the factory. Required customer wiring should be done by a qualified electrician in compliance with OSHA, National Electrical Code, and/or any other applicable state, federal and local electrical codes concerning isolation switches, fused disconnects, etc. A CAUTION The use of plastic bowls on line filters and other plastic airline components without metal guards can be hazardous. Synthetic coolants or the additives used in mineral oils can alter their structural integrity and create hazardous conditions. Metal bowls should be used on any pressurized system for safety concerns. "The Plastic Pipe Institute recommends against the use of thermoplastic pipe to transport compressed air or other compressed gases in exposed above ground locations, e.g. in exposed plant piping." (I) Sullube should not be used with PVC piping systems. It may affect the bond at cemented joints. Certain other plastic materials may also be affected. (I) Plastic Pipe Institute, Recommendation B, Adopted January 19, 1972. SU_0000032 4.4 COUPLING ALIGNMENT CHECK No coupling alignment is required. 4.5 FLUID LEVEL CHECK The air compressor is shipped with the proper amount of fluid installed. However, it is necessary to check the fluid level at the time of installation and during continued operation of the compressor. The oil level is to be checked when the compressor is in the SHUT DOWN MODE (oil level may not be visible when operating), and by looking at the sight glass on the sump. To be able to see the oil level it may be necessary to start the machine and build the sump pressure up to 10/20 psi and then shut down. If no oil level is seen in the sight glass add oil to the center of the glass. Do not overfill in any case. When a complete oil change is performed, fill the sump to the maximum allowable fluid level (up to the fill plug.) ® SULLAIR ® 3700 Operator’s Manual and Parts List NOTE Customer must provide electrical supply power disconnect within sight of machine. The fuse protecting the circuit and the compressor must be selected in accordance with the data provided in the general information section. SU_0000033 • The compressor and drive should be provided with a proper grounding conductor/earthed in accordance with both local and National Electrical Code (NEC) requirements. • Installation of this compressor must be in accordance with recognized electrical codes and any local Health and Safety Codes. • Feeder cables should be sized by the customer/electrical contractor to ensure that the electrical circuit the system is connected to is balanced and not overloaded by any other electrical equipment. The length of wiring from a suitable electrical feed point is critical as voltage drop may impair the performance of the compressor. Cable sizes may vary so the mains terminals will accept from 50 mm2 (1 awg) (37/4 Sk & 50/60 H) to 90 mm2 (3/0 awg) (55/75 k & 75/100 H) cable. • Feeder cable connections to incoming terminals L1-L2-L3 should be tight and clean. The applied voltage must be compatible with the motor and compressor data plate ratings. • A starter hole is provided for incoming power connection. If it is necessary to make a hole in the control box in a different location, care should be taken to not allow metal shavings to enter the starter and other electrical components. If another hole is used, the original hole must be blocked off with a suitable knockout seal. • A few electrical checks should be made to help assure that the first start-up will be trouble-free. 27 SECTION 4 4.8 FAN MOTOR ROTATION CHECK A DANGER Lethal shock hazards exist inside. Disconnect all power at source and lock out before opening or servicing. On initial start-up check that the fan is rotating in the proper direction. The correct rotation is counterclockwise when viewing the fan motor from the driveshaft end. SU_0000034 1. Check incoming voltage. Be sure that compressor is wired for the correct incoming voltage. 2. Check the motor starter for correct size, properly sized overload relay, and correct heaters for the load. 3. Check all electrical connections for tightness. Check all grounding connection for bond. 4. “DRY RUN” the electrical controls by disconnecting the three (3) motor leads from the starter. Energize the control circuits by pressing the “I” (START) pad, and check all protective devices to be sure that they will de-energize the starter coil when tripped. 5. Reconnect the motor leads and jog the motor for a direction of rotation check as explained in Section 4.7. Wiring diagram for standard compressors is supplied with the machine. 4.7 MOTOR ROTATION DIRECTION CHECK Motor rotation check must be made at compressor startup. The compressor will not operate correctly if it runs in the wrong direction. Open the compressor door to view the motor rotation. After the electrical wiring has been done, it is necessary to check the direction of the motor rotation. Pull out the EMERGENCY STOP button and press once, quickly and in succession, the “I” (START) and “O” (STOP) pads. This action will bump start the motor for a very short time. When looking at the motor from the end opposite the compressor unit, the shaft should be turning clockwise. If the reversed rotation is noted, disconnect the power to the starter and exchange any two of the three power input leads, then re-check rotation. A “Direction of Rotation” decal is located on the motor to show proper motor/compressor rotation. An alternative to this procedure is to set the Microprocessor to display P1 sump pressure. Pull out the EMERGENCY STOP button and press once, quickly and in succession, the “I” (START) and “O” (STOP) pads. This action will bump start the motor for a very short time. If motor rotation is correct there will be immediate pressure shown. If no pressure is present, reverse rotation is occurring. Disconnect the power to the starter and exchange any two of the three power input leads. Recheck rotation as outlined above. 28 3700 Operator’s Manual and Parts List ® SULLAIR ® ® SULLAIR ® 3700 Operator’s Manual and Parts List Section 5 WS CONTROLLER 5.1 CONTROLLER LAYOUT Figure 5-1      ¤    1. 2. 3. 4. 5.  6. 7. 8. 9. 10.

The use of the service indicators provided for the fluid filter, air filter and fluid separator, will alert you when service maintenance is required. When the microprocessor display indicates service, maintenance for that specific item is required. See instructions for each item in Section 6.6, Filter Maintenance. 6.2 DAILY OPERATION Prior to starting the compressor, it is necessary to check the fluid level in the sump. Should the level be low, simply add the necessary amount. If the addition of fluid becomes too frequent, a simple problem has developed which is causing this excessive loss. See the Troubleshooting Guide Section under EXCESSIVE COMPRESSOR FLUID CONSUMPTION for a probable cause and remedy. After a routine start has been made, observe the controller display and be sure it monitors the correct readings for their particular phase of operation. After the compressor has warmed up, it is recommended that a general check on the overall compressor be made to assure that the compressor is running properly. 6.3 MAINTENANCE AFTER INITIAL 50 HOURS OF OPERATION After the initial 50 hours of operation, a few maintenance requirements are needed to clean the system of any foreign materials. Perform the following maintenance operations to prevent unnecessary problems. 1. Clean the return line strainer (refer to 6.4, for location). 2. Clean the return line orifice. 6.4 MAINTENANCE EVERY 2000 HOURS After 2000 hours of operation, it will be necessary to perform the following: A WARNING 1. Clean the return line strainer (refer to8.10, for location). 2. Replace the fluid filter element. HIGH-PRESSURE HAZARD! • DO NOT remove caps, plugs, and/or other components when compressor is running or pressurized. Stop compressor and relieve all internal pressure before doing so. • Failure to comply could result in death or serious injury.

The orifice must be removed with an allen wrench. If your compressor is fitted with the standard solenoid condensate drain valve, it is necessary to periodically clean the strainer. Remove the hex cap from the strainer and remove the strainer screen. Clean the screen and reinstall. If the screen is damaged, the strainer assembly must be replaced (P/N 241772). 5. Coat/lubricate the o-rings with silicone grease. CONTROL LINE STRAINER 6. Reattach the connectors to the sight glass/orifice blocks. The regulator and solenoid valve(s), which control the compressor, are protected by a strainer. Every 12 months it is necessary to clean the strainer. Remove the hex cap from the strainer and remove the strainer screen. Clean the screen and reinstall. If the screen is damaged, the strainer assembly must be replaced (P/N 241772). 3. Remove used filter assembly, and replace with new assembly. 36 3700 Operator’s Manual and Parts List ® SULLAIR ® MAINTENANCE SHAFT COUPLING MAINTENANCE The compressor unit and motor are rigidly connected via a mounting adapter housing. This arrangement makes coupling alignment unnecessary. The coupling is a jaw type in shear. If the elastomeric element requires replacement due to wear or breakage, order replacement element no. 02250152-670, and follow the following steps: 1. Remove the protective grill from the adapter housing. 2. Loosen the retaining screw located on the outer sleeve. Slide the sleeve to one side, exposing the coupling element. 3. Unwrap the coupling element from the coupling jaws. 4. Install the new element by wrapping it around the jaws, engaging the cogs on the element into the jaws. 5. Reinstall the outer sleeve and the protective grill. 6.9 TROUBLESHOOTING INTRODUCTION The information contained in the Troubleshooting Guide has been compiled from field report data and factory experience. It contains symptoms and usual causes for the described problems. However, DO NOT assume that these are the only problems that may occur. All available data concerning a problem should be systematically analyzed before undertaking any repairs or component replacement procedures. A detailed visual inspection is worth performing for almost all problems and may avoid unnecessary additional damage to the compressor. Always remember to: 1. Check for loose wiring. 2. Check for damaged piping. 3. Check for parts damaged by heat or an electrical short circuit, usually apparent by discoloration or a burnt odor. Should your problem persist after making the recommended check, consult your nearest Sullair representative. ® SULLAIR ® 3700 Operator’s Manual and Parts List 37 SECTION 6 6.10 TROUBLESHOOTING GUIDE SYMPTOM PROBABLE CAUSE REMEDY COMPRESSOR WILL NOT START Main Disconnect Switch Open Close switch.
