Quincy Compressor recommends that a new or rebuilt reciprocating compres-
sor should be run for a total of 100 hours at full discharge operating pressure
to break-in the new piston rings. Until the rings are seated, the compressor
will discharge higher than normal amounts of lubricant. In light of this fact,
the lubricant level should be checked more frequently during the 100 hour
break-in period.
Daily Starting Checklist
Do not proceed until the
Pre-starting Checklist
and
Initial Starting &
Operating
sub-sections have been read and are thor oughly understood.
Step 1)
Check lubricant level in crankcase.
Step 2)
Drain liquid from the air receiver and moisture trap (if so equipped).
Step 3)
Check all hoses and fittings for weak or worn conditions and re-
place if necessary.
Step 4)
Jog the starter button and check compressor rotation
(refer to
Steps 14 & 15 of Pre-Starting Checklist).
Note: Continuous Run Units - Prior to starting a continuous run
unit, flip the toggle lever on the pilot valve stem to the “Manual
Unload” position (see Fig. 4-2). Now the compressor can be started
unloaded. Once the compressor is running at full speed, flip the
toggle lever back to the “RUN” position.
Step 5)
Start compressor per factory instructions. (Refer to
SECTION 4,
Pre-Starting Checklist and Initial Starting & Operating.
)
Step 6)
Check system pressure.
Step 7)
Check all pressure relief valves for proper operation.
Step 8)
Check control system for proper operation.
Step 9)
Check the lubricant level in the crankcase several minutes after
the compressor has run. (Discoloration or a higher lubricant level
reading may indicate the presence of condensed liquids.) If lubri-
cant is contaminated, drain and replace.
