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.

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.

(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).

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.

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.

INSTALLATION
4.1 MOUNTING OF COMPRESSOR
4.2 VENTILATION AND COOLING
A suitable foundation or fabricated support must be
established to support the compressor. 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.

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.

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

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.)

• 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.

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.

MAINTENANCE
6.1 GENERAL
As you proceed in reading this section, it will be easy to
see that the Maintenance Program for the air
compressor is quite simple. 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.

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.
