OPERATION
Section 5
5.1 ROUTINE OPERATION
Before starting the compressor, check the fluid
level in the receiver tank. If the fluid level is not
showing in the sight glass, add the required
amount of fluid up to the mid-point to bring it to its
proper level. Frequent addition of fluid indicates
the presence of a leak or a condition causing
excessive fluid consumption. See the
Troubleshooting Guide Section under
EXCESSIVE COMPRESSOR FLUID
CONSUMPTION for a probable cause and
corrective action.
After a routine start, observe the controller display for
the proper indications for this phase of operation.
After the compressor has warmed up, check all
compressor operation indications to ensure that it is
running properly.
WARNING
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.
NOTE
Sections 2.7 through 2.11 provide detailed
information pertaining to the operation of the WS
Controller and the VSD (not all compressors
have a VSD).
