Start Up Preparation & Procedures
Drain off condensate from the sump and check the oil level. Refill as necessary.
Check for any oil leaks. Correct as necessary.
On water cooled units, turn on the water.
Press the start button.
Stopping
1. Make sure the compressor is fully unloaded before step 2. Unload the
compressor by closing the service valve (this is a ball or block valve) placed
in the system during compressor installation between the compressor and
operating airlines for service and maintenance reasons.
2. After the unit has exhausted its contained pressure (this takes about 30
seconds) push the stop button.
Emergency Stopping
Push the stop button.
Pull the main disconnect, if possible.
Air Filter
The air filter is the primary protection of the compressor from harmful dirt being
ingested into the oil system. It needs to be looked at periodically for clogging or
holes. The period for theses inspections is dependent on the environment the
machine is in. For optimum life it is recommended that an air filter restriction
indicator be used. Service simply based on hours is not recommended.
Element Inspection and Replacement
Switch off the unit and disconnect the power to prevent accidental starting.
Allow one minute after stopping for the system to settle and the pressure
to be relieved.
Loosen the nut that secures the cover and remove the cover.
Remove the element.
Place a bright light inside the element to inspect for damage or leak holes.
Inspect all gaskets and gasket contact surfaces of the housing. Correct any
faulty conditions immediately.
Clean the housing with a damp cloth. Do not attempt to blow out dirt with
compressed air.
Place a new element in the housing.
Replace the cover and tighten the nut.
