Continuous Run Pilot Valve
A new or rebuilt reciprocating compressor should be run for a total of 100
hours at full discharge operating pressure to breakin 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 breakin period.
Daily Starting Checklist
Do not proceed until the
Pre-starting Checklist
and
Initial Starting &
Operating
subsections have been read and are thor oughly understood.
Step 1)
Check the lubricant level in the crankcase.
Step 2)
Check all hoses and fittings for weak or worn conditions and re
place if necessary.
Step 3)
Drain liquid from the air receiver (refer to Section 3, Manually
Draining An Air Tank) and moisture trap (if so equipped).
Step 4)
Jog the starter button and check compressor rotation.
Note: Con-
tinuous Run Units - Prior to starting a continuous run unit, flip
the toggle lever on the pilot valve stem to the “MANUAL UNLOAD”
position (see below). Now the compressor can be started unloaded.
Once the compressor is running at full speed, flip the toggle 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 cooling fan.
Step 8)
Check all pressure relief valves for proper operation.
Step 9)
Check control system for proper operation.
Step 10) 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.
