Operating Instructions
Installation (Continued)
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.
Before resuming operation, the electrical
equipment and all safety-relevant 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.
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.
