Routine Start/Stop
The unit must not be operated unless coupling guard is in place. Failure to
observe this warning could result in personal injury to operating personnel.
Never attempt a restart until the compressor has completely come to rest.
Prior to starting, the operator should become familiar with the operation of the main driver.
Refer to the driver manufacturer's instructions. The operator should also be familiar with all
the accessory equipment and optional equipment contained on the unit.
Personnel who are unfamiliar with the compressor package should not start, operate or
tamper with the equipment. Only fully trained personnel should be allowed to start and
operate this compressor. The following procedure is a guideline for the fully trained

Adjust the seal air regulator if necessary.
4.
Check the main driver and compressor oil level.
5.
Turn on the electrical power to the control panel. The prelube pump should start.
6.
Check the oil pressure to the compressor casing. This should be 20 PSIG (nominal).
7.
Check the oil temperature. This should be 95°F (nominal).
8.
Check to see that the inlet valve is closed and the bypass valve is open.
9.
Open the isolation block valve in the discharge air line.
10.
Drain residual condensate from the compressor casing by opening each condensate trap
bypass valve.

Drain any condensate from the air inlet piping drip leg.
12.
Check the discharge pressure set point. Adjust if necessary.
13.
Press the start button on the control panel.
