Do not lift or move unit without appropriately
attached to lifting device used. Do not lift unit by holding onto tubes or coolers. Do not use unit to lift other attached equipment.
Never use the wood shipping skids for mounting
PICKING THE LOCATION
Install and operate unit at least 36 inches from any obstructions in a clean, ventilated area. The surrounding air temperature should not exceed 100° F or fall below 40° F. This will ensure an unobstructed flow of air to cool compressor and allow adequate space for maintenance.
Do not locate the compressor air inlet near
source of contamination.
NOTE: If compressor operates in a hot, moist environment, supply compressor pump with clean, dry outside air. Supply air should be piped in from external sources.
TANK MOUNTING
The tank should be bolted into a flat, even, concrete floor or on a separate concrete foundation.
If using isolator pads, do not draw bolts tight. Allow the pads to absorb vibrations. When isolators are used, a flexible hose or coupling should be installed between the tank and service piping.

PIPING
Never use plastic (PVC) pipe for compressed air.
Serious injury or death could result.
Any tube, pipe or hose connected to the unit must be able to withstand the temperature generated and retain the pressure. All pressurized components of the air system must have a pressure rating of 200 psi or higher. Incorrect selection and installation of any tube, pipe or hose could result in bursting and injury. Connect piping system to tank using the same size fitting as the discharge port.
INSTALLING A SHUT-OFF VALVE
A shut-off valve should be installed on the discharge port of the tank to control the air flow out of the tank. The valve should be located between the tank and the piping system.
Never install a shut-off valve between the
compressor pump and the tank. Personal injury and/or equipment damage may occur. Never use reducers in discharge piping.
When creating a permanently installed system to distribute compressed air, find the total length of the system and select pipe size from the chart. Bury underground lines below the frost line and avoid pockets where condensation can gather and freeze.
Apply air pressure to the piping installation and make sure all joints are free from leaks BEFORE underground lines are covered. Before putting the compressor into service, find and repair all leaks in the piping, fittings and connections.
WIRING (see page 9 for wiring diagrams)
All wiring and electrical connections must be
performed by a qualifi ed electrician familiar with induction motor controls. Installations must be in accordance with local and national codes.
Overheating, short circuiting and fi re damage
will result from inadequate wiring.
Wiring must be installed in accordance with National Electrical Code and local codes and standards that have been set up covering electrical apparatus and wiring. These should be consulted and local ordinances observed. Be certain that adequate wire sizes are used, and that:
1. Service is of adequate ampere rating.
2. The supply line has the same electrical characteristics
(voltage, cycles and phase) as the motor. Refer to motor name plate for electrical ratings and specifications.
3. The line wire is the proper size and that no other equipment
is operated from the same line. The chart gives minimum recommended wire sizes for compressor installations.

MINIMUM WIRE SIZE
(USE A MINIMUM OF 75°C COPPER WIRE)
Make sure voltage is correct with the motor wiring. NOTE: If using 208 volts single phase, make sure the motor
name plate states it is rated for 208 volts single phase. 230 volt single phase motors do not work on 208 volts unless they have the 208 volt rating.

GROUNDING
Improperly grounded electrical
components are shock hazards. Make sure all the components are properly grounded to prevent death or serious injury.
This product must be grounded. Grounding reduces the risk of electrical shock by providing an escape wire for the electric current if short circuit occurs. This product must be installed and operated with a cable that has a grounding wire.
BREAKERS AND FUSES
The entire electrical system should be checked by a certified electrician. Time delay breakers and fuses are required for this compressor. A tripped breaker or blown fuses may indicate a direct short to ground, high current draw, improper wiring, incorrect fuse or breaker size and/or type. This needs to be evaluated by a certified electrician.
MOTOR HOOKUP AND STARTER INSTALLATION
Branch circuit protection must be provided as specified in the United States National Electrical Code, Chapter 2, “Wiring Design and Protection.” Article 210, using the applicable article “For Motors and Motor Controllers,” (Article 430, Table 430-1 52).
DIRECTION OF ROTATION
NOTE: Improper rotation will result in failure or compressor. The direction of rotation must be counterclockwise (as shown
by the arrow on the air end in Figure 6) while facing the flywheel side of the pump.
The direction of rotation of 3 phase motors can be reversed by interchanging any two motor-line leads.
Rotation
Figure 6 - Direction of rotation
CHECKING ROTATION DIRECTION
ROTATION DIRECTION: rotating to the left (counterclockwise) looking at the shaft.
The rotation direction of the screw compressor
system must be checked during initial start-up and each time changes are made to the electrical supply line of the electric motor drive. For this purpose, switch on the drive motor briefl y and then switch off again immediately. ROTATION FOR MORE THAN 2 SECONDS IN THE WRONG ROTATION DIRECTION WILL DESTROY THE SCREW COMPRESSOR. If necessary, reverse the connections of the connecting cable.

OIL LEVEL CHECK (See Figure 7)
• Check oil level by removing oil plug.
• With hot oil, the level will be higher than with cold oil. As a result, oil may escape when the oil plug is opened at the
maximum oil level. If this does happen, close the oil plug immediately and carefully clean up the oil that has escaped.
NOTE: The oil plug is provided with a safety hole on the side from which oil or air escapes if there is any residual pressure in the air end. Wait for one minute after the unit is at standstill before opening the oil plug.
1. Switch off the system, prevent it from being switched back on without authorization.
2. Wait for one minute at standstill.
3. Unscrew the oil plug on the filler neck by hand with the air end depressurized.
4. Check the oil level.
5. If necessary, top off oil of the same oil type and the same brand up to the maximum level (see Figure 7 and Lubrication section).
NOTE: The oil filler neck is positioned so that it is not possible to overfill the system. Excess oil runs out of the filler neck.
6. Screw on the oil plug firmly by hand.
7. Switch on the system.
8. Wipe off and clean up any spilled oil.
START-UP INFORMATION
READ AND UNDERSTAND ALL STEPS BELOW
BEFORE TURNING ON POWER .
1. Check oil level (See Figure 7).
2. If it has been longer than 12 weeks since the compressor has been operated the air end must be primed with 8 ounces of oil.
units must be checked for leaks and proper function. Loose connections must be refastened and damaged lines must be replaced.
Screw compressor systems that are switched off, shut down,
or stored for longer than 12 weeks cannot be placed into operation again until after the following steps have been carried out:
a. Manually rotate the compact module screw compressor
in the rotation direction several times.
b. With the compressor system stopped, add approximately
8 ounces of oil (same oil type as in the air end) into the rotor chamber (see Figure 9).
c. Once again, manually rotate the compressor module
compressor stage in the rotation direction several times.
Before resuming operation, the
electrical equipment and all safety-relevant
Prime Port
Pulley
Figure 9 - Air End Priming Location
d. Check the oil level in the air end and top off if necessary
(see Maintenance section).
e. Monitor operation of the compressor system for at least
15 minutes, but at least until the steadystate temperature is reached (continuous operating temperature).
3. Direction of rotation must be checked. Operation of the
air end for more than 2 seconds in the wrong direction will destroy the screw compressor.
4. Check direction of rotation by quickly bumping the power to ON and having someone else watch the motor pulley to see which way it turns. Belt guard should remain installed. Also check the direction of rotation of the oil cooler fan. The fan must suck air in from the wire guard side and push air out through the radiator when turning the correct direction. This can be checked by holding a small strip of paper in front of the radiator. With the correct direction of rotation the paper will blow out away from the radiator.
5. Reset E-Stop switch if needed (see Figure 8).
6. Turn on the incoming power at the disconnect switch/circuit breaker. The White incoming power indicator lamp will illuminate. The motor will not turn on with this step.
7. Turn the on/off switch to the On position. The green lamp will illuminate indication the compressor is ready to run. The RED High temperature/High Pressure Failure Lamp will illuminate. The motor will not turn on with this step.
8. Keep your hand on the on/off switch ready to turn off immediately after start up to check the rotation direction. Also check the direction of the cooler fan.
9. The motor can now be started by pressing the High temp/ high pressure reset. The red lamp is also a momentary contact switch. The motor will start with this step.
10. Immediately turn off the on/off switch. The motor will stop with this step.
11. If the direction of rotation is incorrect, disconnect, lock out and tag out all incoming power. Change the position of two of the incoming power lines and repeat steps 5-10.
12. When the direction of rotation has been confirmed the compressor is ready to run for an initial start up operation check.
