Do not attempt to operate the Unit without first checking
whether there is oil in the Pump. Add oil as required. Serious
damage may result from use, however limited, without oil.
Initial Start-up
1) Remove the Oil Filler Plug, and ensure that there
is sufficient Oil in the Crankcase. Refer to the
‘Lubrication’ section (Page 8) in this manual for
proper type and level of Oil.
2) Replace the Oil Filler Plug, and use a
crescent wrench to tighten snug plus 1/4 turn.
3) Do a visual inspection of the Unit, and ensure
that all Bolt heads are sufficiently tightened. This
must be done, as some fasteners may become
loose in transit.
4) Turn the Compressor 'On' momentarily by
positioning the Fused Disconnect or Breaker in
the 'On' position. Ensure that the Flywheel is
turning in the correct direction. See the ‘Pump
Rotation’ (Page 10).
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.
6) After having run the Unit unloaded for 30
minutes, close the Ball Valve, and allow the Unit
to reach maximum operating pressure.
7) Ensure that the Compressor shuts off at the
factory preset maximum pressure, and the head
pressure is released through the Unloader at
either the front of the Pump (the ‘CPR’) or at the
Pressure Switch.
8) Measure the amp draw as the Unit reaches
maximum pressure.
9) Once off, check the Compressor and piping
systems for any air leaks. Correct as required.
Shut off all power to the Compressor Unit
before attempting any repair or maintenance.
During the first few days of operation, check the Unit
periodically to ensure it is running smoothly. Should you have
any concerns, contact your DV Systems Distributor.
On Compressors with 3 phase power, switch
‘L1’ and ‘L3’ at the input into the Magnetic
Starter if the rotation is incorrect.
5) Open the Compressor’s Ball Valve, and start the
Unit. Ensure that air is escaping to atmosphere.
Allow the Unit to operate in this fashion for 30
minutes. This lubricates the Pistons, Bearings,
and all internal surfaces.
10) With the Unit shut off, check the oil level in the
Pump. Add oil as necessary.
11) After the Unit has run for 40 hours (or 2 weeks),
retorque the Pump Bolts. Refer to the appropriate
Pump Bulletin for torque values.
