System Components
Note
* Required system components.
* Bleed Type Master Air Valve (B)
Trapped air can cause the pump to cycle
unexpectedly, which could result in serious injury
from splashing or moving parts.
• 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 (C)
Automatically opens to relieve air pressure if supplied
pressure exceeds preset limit.
* Air Filter (D)
Removes harmful dirt from compressed air supply. A
minimum 40 micron filter is used.
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 gauge (E).
* Fluid Drain/Purge Valve (J)
Open valve to relieve pressure and when flushing or
priming pump. Close valve when spraying.
De-Ice Contol (T)
Turn bleed air knob (open) to reduce icing.
Grounding
The equipment must be grounded to reduce the risk
of static sparking. Static sparking can cause fumes
to ignite or explode. Grounding provides an escape
wire for the electric current.
Tools Required:
• Grounding wires and clamps for pails
• Two 5 gal. (19 liter) metal pails
1. Connect the ground wire (244524) (L) to the
ground stud on the air motor.
Figure 3
2. Connect the other end of the ground wire to a
true earth ground.
3. Ground the object being sprayed, fluid supply
container, and all other equipment in the
work area. Follow your local code. Use only
electrically conductive air and fluid hoses.
4. Ground all solvent pails. Use only metal pails,
which are conductive, placed on a grounded
surface. Do not place pail on a nonconductive
surface, such as paper or cardboard, which
interrupts grounding continuity.
