System Components
* Required system components.
* Bleed Type Master Air Valve (B)
• Be sure the valve is easily accessible from the
pump and located downstream from the air
regulator.
• Required in your system to relieve air trapped
between it and the air motor when the valve is
closed.
- Open the valve to supply air to the motor.
- Close the valve to shut off air to the motor, and
bleed any trapped air from the motor.
* Air Pressure Relief Valve (D)
Automatically opens to relieve air pressure if the
supplied pressure exceeds the rated limit.
Air Filter and Water Separator (X)
Remove harmful dirt from compressed air supply. A
minimum of 40 micron filter should be used if filtration is
necessary.
Air Regulator Adjustment (G)
Adjusts air pressure to the motor and fluid outlet
pressure of pump. Locate it close to the pump. Read air
pressure on air pressure gauge (E).
* Fluid Drain/Purge Valve (J)
Open valve to relieve pressure and when flushing or
priming pump. Close valve when spraying.
De-Ice Control (T)
Turn bleed air knob (open) to reduce icing.
Trapped air can cause the pump to cycle
unexpectedly, which could result in serious injury
from splashing fluid or moving parts. Perform the
, page 10, to remove
trapped air.
