Minimum Pressure Check Valve
The WHASP tank has a built-in Minimum Pressure Check Valve (MPCV) to
maintain a minimum pressure of approximately 60 psi (410 kPa) in the
WHASP tank. This ensures compressor lubrication and cooling, as well as oil
separation in the coalescing filter. Air will not flow out of the WHASP tank
until around 60 psi of air pressure is reached. The MPCV is factory set and
requires no adjustment or servicing.
A separate check valve is not recommended or required when
connecting the WHASP tank to the receiver tanks.
Hose Information
Depending on other installed equipment, it might be necessary to move the
air/oil separation tank from its intended location. The hoses used in VMAC
compressor systems have a specific inner liner that is compatible with VMAC
compressor oil. Use of hoses other than those supplied or recommended by
VMAC may cause compressor damage and may void your warranty. Please
contact VMAC for replacement hoses and further information.

Safety Precautions
Compressor Air and Oil Hazard
The compressor system is under sufficient
pressure that a leak could force the air/oil mixture
through the skin directly into your bloodstream.
This could cause serious injury or death.
Ensure the system is completely depressurized
before attempting maintenance or repair.
Do not use compressor air to clean off clothing or
skin, compressed air can penetrate the skin
causing serious injury or death.
Do not move or service the compressor while it is
pressurized or operating.
Do not move the compressor by pulling on any
hoses.
Components and hoses under pressure could
separate suddenly, fly out and cause serious injury
or death. If equipped, the auxiliary air tank must be
drained before servicing any components in the
compressor system.
Never adjust or attempt to make any repairs to the
system while the engine is running. Components
and hoses under pressure could fail and cause
serious injury or death.
Burst Hazard
Serious injury or death may result from an air tank
explosion.
Never exceed manufacturer’s maximum air
pressure rating.
Do not repair components, only replace with
approved parts.
Do not tamper with or disable factory safety
equipment.
Moving Parts Hazard
Before performing service, disconnect the battery
and disconnect the spark plug wire to prevent
unexpected engine start.
Do not operate the compressor without guards in
place. If the guards are damaged or missing,
replace them before operating the equipment.

System Testing
Start the G30 Gas drive and allow it to build to pressure.
Ensure the system is operating normally. When the G30 is shut off, the
WHASP tank should vent out of the blowdown muffler; the pressure in
the receiver tanks should hold and maintain a steady pressure reading.
If system does not operate normally ensure lines are connected correctly
and that there are no air leaks. If the problem still persists, contact
VMAC Technical Support at 1-888-241-2289 or tech@vmacair.com.

Operation and Maintenance
When the compressor is no longer needed, shut the compressor system
down, and open the manual drain valve (located on the bottom of the
receiver tanks). This will drain moisture out of the tanks, and will help prevent
rust or contaminants from getting into the air line or tools (Figure 1.14).
Figure 18 - Draining the Tanks
(Dependent upon manufacture date, tank crossover tube may not be installed)
Do not operate the compressor with the ball valve wide open
and no tool attached, this may cause oil-carry over (Figure
19).
