Do not attempt to operate the Unit without first checking
whether there is oil in the Oil Reservoir. Add oil as required.
Serious damage may result from use, however limited, without
1) Remove the Side Door, and ensure that there is
sufficient Oil in the Oil Reservoir. Refer to the
‘Lubrication’ section (page 9) in this manual for
proper type and level of Oil.
2) Do a visual inspection of the Unit, and ensure
that all fasteners are sufficiently tightened. This
must be done, as some fasteners may become
loose in transit.
Start-up Procedures
Do not place any materials in close proximity
to the Compressor. Placing materials against
or close to the Unit will limit the cooling
required, and could lead to premature failure.
3) Place the Fused Disconnect / Breaker in the ‘On’
Position. Check that there is power to the
Controller.
4) During normal operation of the Unit, keep the
Access Panels closed at all times.
5) Ensure the Ball Valve on the Unit is closed, press
the ‘Start’ Button, and run the Unit up to
maximum pressure. The Unit will run up to
approx. 110 psi, at which point the Motor will
continue to run but not compress air.
6) Once the Unit reaches 110 psi, it will idle for 2
minutes and shut off.
7) Open the Ball Valve slightly and allow the air to
bleed from the Tank. Once the pressure reaches
approx. 100 psi, the Unit will start and begin to
compress air after a short delay.
8) Measure the amp draw as the Unit reaches
maximum pressure.
9) Close the Ball Valve, allow the Unit to reach
maximum pressure, idle, and shut off. Once off,
check the various fittings etc inside the Cabinet to
ensure there are no internal leaks.
10) Once you are confident that there are no internal
leaks, the Unit will be ready for normal use.
Shut off all power to the Compressor Unit
before attempting any repair or maintenance.
Adjusting the settings of the Controller could adversely affect
the performance of the Unit. Only those individuals with
knowledge of the Unit should make any adjustments.
