OPERATING INSTRUCTIONS
IMPORTANT:
Check motor rotation before operating the compressor.
All lubricated compressor pumps discharge some condensed water and oil with the compressed air. Install
appropriate water/oil removal equipment and controls as necessary for the intended application.
Failure to install appropriate water/oil removal equipment may result in
damage to machinery or workpiece.
Guarding
The belt guard provided must be installed before operating the unit.
All moving parts must be guarded. All electrical covers must be installed before turning on the power.
Recommended Break-In Period
The compressor should be run continuously for one hour to allow proper seating of the piston rings.
1. Open drain cock completely and run the compressor for 60 minutes.
2. Turn off the compressor and close drain cock. The compressor is now ready for use.
Pressure Switch, Start - Stop
NOTE:
This compressor has a maximum operating pressure of
175 PSI for two-stage compressors or 135 PSI for single stage
compressors. Do not alter pressure settings on control components
above this limit.
The compressor unit starts and stops based on preset pressure switch
settings. The pressure switch contains an unloader which is a small
valve that vents air to allow the motor to start easily (See Figure 9).
Crankcase Breather
During severe operating conditions or initial start-up, some oil may
accumulate at the crankcase breather opening. This is normal and
will diminish as the pump accumulates run time and the piston rings
become fully seated.
Draining Tank
Condensation must be drained from the tank daily.
Duty Cycle
Each pump on this compressor is designed to operate up to 75% of the time. Long-term or on-time operation
over 75% could decrease the life of the pump and motor.
