SECTION 4 START-UP & OPERATION
Pre-starting Checklist
Never assume a compressor is safe to work on just because it is not
operating. It could restart at any time. Follow all safety precautions
outlined in SECTION 5, Stopping For Maintenance.
Failure to perform the pre-starting checklist may result in me-
chanical failure, property damage, serious injury or even death.
Steps 1 through 12 should be performed prior to connecting the
unit to a power source. If any condition of the checklist is not satisfied,
make the necessary adjustments or corrections before starting the compressor.
Step 1) Remove all installation tools from the compressor and check for
installation debris.
Step 2) Check the lubricant level in the crankcase. (Refer to SECTION
5, Lubrication for quantity and types of lubri cant to be used.)
Step 3) Check motor pulley and compressor sheaves for alignment and
tightness on shaft. (Refer to SECTION 5, Pulley / Sheave
Alignment & Belt Tension.)
Step 4) Manually rotate the compressor sheave several rotations to be
sure there are no mechanical interferences.
Step 5) Check inlet piping installation (Refer to SECTION 3, Induction
System.)
Step 6) Check belt tension. (Refer to SECTION 5, Pulley / Sheave
Alignment & Belt Tension.)
Step 7) Check all pressure connections for tightness.
Step 8) Make sure all pressure relief valves are correctly in stalled. (Refer
to SECTION 3, System Components.)
Step 9) Be sure all guards are in place and securely mounted. (Refer to
SECTION 3, System Components.)
Step 10) Check fuses, circuit breakers, and overload relays for proper size.
Verify that the supply voltage matches the motor requirements.
(Refer to SECTION 3, Electrical Supply Requirements.)
Step 11) Open all manual shutoff valves at and beyond the compres sor
discharge.
Step 12) After all the above conditions have been satisfied, the unit can be
