BURN HAZARD!
• The Scroll Pump generates heat during operation. Use caution when servicing to avoid burns.
BURST HAZARD!
• Check the manufacturer’s maximum pressure rating for air tools and accessories. Compressor outlet pressure must be regulated to
never exceed the maximum pressure rating of the tool. Relieve all pressure through the hose before attaching or removing accessories.
• DO NOT adjust the Pressure Relief Valve for any reason. The Pressure Relief Valve has been pre-set at the factory for the maximum
safe pressure of this unit. Personal injury and/or property damage may result if the relief valve is tampered with.
• Use only hose, pipe and fittings rated for compressed air distribution lines. Do Not use plastic or PVC pipes.
• Drain the moisture from the tank daily. An empty, dry tank will help prevent corrosion and prolong tank life.
• To provide proper ventilation for cooling and prevent overheating, the compressor must be kept a minimum of 3’ (31 cm) from the near-
est wall, in a well–ventilated area. DO NOT allow the Cover ventilation holes to be blocked or possible permanent damage could occur.
• REQUIRES 208-240 VAC, 60Hz., 3 phase.
COMPRESSOR SITE LOCATION
• The Eastwood Elite QST-80/120 Scroll Compressor must be located in an indoor area, on a firm, clean, level surface. A solid, level concrete floor is best.
• Select an area with adequate ventilation and air circulation. A minimum of 3’ [90 cm] of free space must be maintained around all sides and above the
compressor. This is to allow for adequate ventilation and panel removal and to allow room for access for maintenance purposes. Do not store objects
behind, alongside or on top of the compressor.
• Do not place the Scroll Compressor in an area where dust and debris can be drawn into the cooling vents and air intake or severe damage to the unit
can occur.
• The temperature environment for proper operation must be between 32°F and 110°F [0°C and 43°C]. The Compressor is equipped with over temperature
shut off circuitry which may activate in excessive ambient temperature conditions.
• For best performance, humidity levels should be below 75%. For extended operation in higher humidity environments, particular attention should be
devoted to draining tank of moisture.
FIRE OR EXPLOSION HAZARD!

COMPRESSOR SET-UP
• Level Scroll Compressor - Using an accurate level, check to see that
the Scroll Compressor is level and not prone to rocking or vibration.
Use suitable shims under the corners of the frame, if necessary, to achieve
a level condition.
• Remove Panels - Access to all interior components is by panel removal.
All four sides and top panels are removable:
- Front rear and side panels are removed by placing the included
triangular profile key over the triangular posts of the latches (FIG 1).
Front and rear panels have 2 latches each and are released by turning
the key 1/4 of a turn to the respective outside corner. End panels have
one latch each and are released with 1/4 turn to the right.
- After latch release, lift panel off locating pins on the outer floor of the
unit then pull up and away (FIG 2).
- The top panel is removed by inserting a 5mm hex key into the holes at
the corners and loosening the socket head cap screws.
NOTE: Do not remove the screws as the underside flange of the top
panel has “Keyhole” slots. Standing at the rear of the Compressor, slide
the top panel to the right to clear screw heads and lift off (FIGS 3 & 4).

• Check Oil Level – The Scroll Compressor is shipped with the correct
amount of Scroll Compressor Oil, however the oil level should be verified
as it is extremely critical to the function of the Scroll.
- View the Sight Gauge on the side of the Oil Reservoir to make sure
that it reads FULL (at or above the “M” line but not above the
“H” line (FIG 5).
- If the oil level is below the “M” line, oil must be added.
- If needed, remove the Fill Plug form the Oil Reservoir with a 22mm
wrench (not included) and add #31718 Eastwood Scroll Compressor Oil
to the fill port of the Oil Reservoir using a suitable funnel (FIG 6).
- Check the condition of the seal then replace Oil Fill Plug and tighten
securely.
• Check Air Filter – Clean, filtered intake air is vital to the life of the Scroll
as it is machined to extremely close tolerances.
- Check that the Cover on the Air Filter is latched correctly and hasn’t
vibrated loose in shipment. The two molded in arrows on the base and
lid should be aligned (FIG 7).
AIR LINE CONNECTION
To utilize the maximum performance from the Compressor, it is strongly recom-
mended to use 3/4” or larger air lines and fittings throughout your system.
The use of 3/8” or smaller lines and fittings will greatly hamper performance.
In order to protect valuable air tools and equipment and prevent contamina-
tion, it is strongly advisable to use a suitable, high efficiency Air Regulator
(not included) and Moisture/Oil Separator (not included) in a well-planned
air line layout.
If the oil level is found to be low, check all lines, fittings, oil
reservoir and heat exchanger for any signs of leakage from
shipping damage before continuing.

ELECTRICAL CONNECTION
1. The 3 phase wiring connections are made at the Upper Terminals of the
Electrical Box (FIG 8).
2. The Scroll Compressor features a microprocessor in the control unit
Control Panel Display which will detect incorrect phasing and will display
“ALARM1:” “PHASE REVERSE” and an audible alarm will sound.
3. If these conditions occur, it is an indication that the 3 Phase connections
have been done incorrectly. To correct, shut off power at main breaker
disconnect switch and revise the connection sequence of the three phase
upper terminals of the Electrical Box (FIG 11).
4. Press the SET Button to cancel alarm and reset the Error message in
the LCD Display window.
FIG. 8
The 3 phase wiring connections MUST be done in the proper
sequence or the motor could possibly run in reverse which
could cause severe and permanent damage to the Scroll.
✓
3 PHASE REQUIREMENTS
• 208-240V, 60Hz, 22-amp, 3 phase voltage and amperage requirements. All wiring must be done by a licensed electrician, in accordance with
National Electric Code and state and local requirements. For best performance, the Compressor must be installed on a dedicated circuit, with
circuit breaker or fuse protection. Each time the Compressor motor starts, it will momentarily draw several times its full load amperage.
It is important to consider this start-up surge when specifying circuit breakers or fuses. If fuses are used, time-delay type must be installed.
• The voltage variation between the rated input voltage requirements and that of the actual input voltage supply must not exceed +/- 10%.
If greater variation exists, a step-up or step down transformer must be installed.
• The voltage variation between legs of the 3-phase supply must be within 5%. If greater variation exists, a voltage regulator or rectifier must
be used.
• The power supply wiring must be adequately sized to prevent dangerous overheating and low voltage at the Compressor during startup and
running. Low voltage will cause difficult starting, overheating, and excessive tripping of circuit breakers. The wire gauge must be increased for
longer wire runs to accommodate the increased resistance inherent in longer runs. Refer to the National Electric Code to determine the proper
wire gauge for your wire run length. Low voltage can also be caused by low supply voltage from the power company, or from other equipment
running on the same line.
• For safety reasons, install a main breaker disconnect switch in the line from the electrical panel to the Compressor within momentary reach
of the Compressor. When the switch is off, all power to the Compressor is disconnected. When the switch is on, the compressor will start and
stop automatically as it will be controlled by the pressure switch.

As an added precaution, the following check should be performed before starting the Compressor for the first time:
1. Obtain the assistance of an observer and view the Motor cooling fan blades visible through the screened housing at the end of the Motor case (FIG 10).
2. Have the same observer note the directional arrow label on the Motor case (FIG 10).
3. Depress the “START” Button of the Control Panel.
4. If the observer views the cooling fan begin to rotate in the opposite direction of the directional arrow label, depress the “OFF” Button immediately!
5. If 3 phase connection corrections are required, do so and repeat check sequence beginning at step 1.
6. If correct rotation of the Motor has been verified, proceed to COMPRESSOR OPERATION.
FIG. 10 FIG . 11
COMPRESSOR OPERATION
• Depress the “START” Button of the Control Panel (FIG 9).
• Allow the Tank pressure to build to 145 PSI [10 bar] before each use. With the Air Compressor turned on, operation is automatic and under the control of
the internal Pressure Controller. It will turn off @ 145 PSI [10 bar] and automatically restart @ 115 PSI [8 bar].
The Pressure Gauge is visible through the upper right-side Compressor Panel and indicates the actual output line and tank pressure.
When the pressure reaches the 145 PSI [10 bar] cutoff point, an Unloader Valve will automatically release static pressure in the
Scroll to allow it to easily restart without needing to overcome residual pressure. This produces a momentary audible “hiss” or
“burbling” sound and is normal.

THERMAL OVERLOAD PROTECTION
As long as the air output capacity, 31.8 SCFM @ 90 PSI [900 l/min. @ 6.2 bar], of the Eastwood Elite QST-80/120 Scroll Compressor is not exceeded, it is ca-
pable of running continuous, automatically controlled on/off cycles. If the air output is exceeded, the Compressor will run continuously in efforts to meet demand.
If this occurs, the Motor and or Scroll will overheat. When the Compressed Air Outlet Temperature Sensor detects 203°F [95°C] the Thermal Overload alarm will
activate (audible warning buzzer and LCD Screen Warning display) however, the Motor will continue to run for a short period. At this point, all work demands of
the Compressor should be stopped immediately and the unit should be allowed to continue to run without a load until it cools. This will automatically cancel the
Thermal Overload LCD Screen Warning, however, the audible warning buzzer alarm must be reset by pressing the Button (FIG 9).
If the Thermal Overload warning in not heeded, the Motor will shut off when the Compressed Air Outlet Temperature Sensor detects 212°F [100°C]. The cooling
fan will continue to run. The motor will not start until it has cooled sufficiently.
OIL TEMPERATURE ALARM
In addition to the Motor and Scroll overheating protection, the Oil Over Temperature sensor constantly monitors the Scroll oil temperature. If the oil temperature
becomes excessive, the Oil Over Temperature alarm will activate (audible warning buzzer and LCD Screen Warning display) however, the Motor will continue to
run for a short period. At this point, all work demands of the Compressor should be stopped immediately and the Compressor housing should be checked for
blockage of cooling air side vent panels, or blockage of the Fan Air Outlet on top.
The Fan should be allowed to continue to run until the oil sufficiently cools. This will automatically cancel the Oil Over Temperature LCD Screen Warning however,
the audible warning buzzer alarm must be reset by pressing the Button (FIG 9).
If the Oil Over Temperature warning is not heeded, the Motor will shut off and will will not start until the oil has cooled sufficiently.
LOW OIL LEVEL ALARM
In addition to the Motor and Scroll overheating protection, the Oil Level sensor constantly monitors the Scroll oil level. If the oil level becomes too low, the
Low Oil Level alarm will activate (audible warning buzzer and LCD Screen Warning display) and the Motor will stop running.
The oil level must be checked and filled with the necessary amount of Eastwood Scroll Compressor Oil and the alarm must be reset by pressing the
Button (FIG 9).
The Scroll, Oil/Moisture Tank, and all lines should be checked for leaks to determine the reason for the low oil condition before resuming use.
PRESSURE RELIEF VALVE
The Pressure Relief Valve (FIG 31) is factory set to release at 160 PSI
[11 bar]. DO NOT attempt to adjust or tamper with it. Doing so can cause
an unsafe condition resulting in violent bursting of lines, tank or other
components.
If the Pressure Relief Valve should suddenly release, this indicates that a
dangerous condition exists! Stop all work immediately and quickly depress
the large “STOP” Button located on the Control Panel. DO NOT resume
Compressor use until a cause for the pressure release has been found.

MAINTENANCE SCHEDULE
DRAIN CONDENSATION
In normal compressor use particularly in humid environments, moisture will condense and collect in the tank.
All tanks must be drained of moisture daily. Failure to do causes internal tank corrosion, perforation and ultimate failure.
The following is the moisture draining procedure for the optionally available Eastwood #32501, 80 Gallon Vertical Tank: (other tanks supplied by customer may
vary in detail)
1. Press the “OFF” Button and shut off main power.
2. Release all pressure from the Tank until the Tank Pressure Gauge reads less than 20 PSI.
3. Slowly open the Drain Valve of the tank (will vary with tank design).
4. Drain moisture from tank into a suitable container.
• Clean dirt and debris from cooling air vents. Use a semi-firm brush or compressed air to keep cooling air passages free from dirt or debris accumulation.
Only SLIGHTLY open the water Drain Valve to blow air and moisture out of the Tank.
Opening it all the way or too quickly will cause contaminated water to be blown out at high velocity. Wear appropriate eye protection.
Condensate is a polluting material and should be disposed of in compliance with local regulations. If drain valve becomes clogged,
release all air pressure, remove and clean valve, then reinstall.
