Start-up Procedures
Do not attempt to operate the Unit without first checking whether there is oil in the Air
End Reservoir. Add oil as required. Serious damage may result from use, however
limited, without oil.
Initial Start-up
1) Remove the LH Side Access Panel, and
ensure that there is sufficient Oil in the Air
End. Refer to the ‘Lubrication’ section (page
8) 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.
3) Place the Fused Disconnect or 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. As well,
do not place any obstructions against or on
top of the Unit, thereby limiting the flow of
cooling air.
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. 145 psi (10bar), at which point the
Motor will continue to run but not compress
air.
6) Once the Unit reaches 145 psi (10bar), it will
idle for 5 minutes and shut off.
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.
7) Open the Ball Valve slightly and allow the air
to bleed from the Tank. Once the pressure
reaches approx 120 psi (8.3bar), the Unit will
start and begin to compress air after a short
delay.
8) Measure the amp draw when the Unit
reaches the maximum pressure of 145 psi
(10bar).
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) The Unit is ready for normal use.
11) To validate Warranty, complete the warranty
registration and attach to the on-line Startup
claim within Thirty (30) days of initial
operation, or email to:

Shut off all power to the Air
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.
