Grounding
Proper grounding is an essential part of maintaining a
safe system.
To reduce the risk of static sparking, ground the pump.
Check your local electrical code for detailed grounding
instructions for your area and type of equipment. Be
sure to ground all of this equipment:
D
Pump: Use a ground wire and clamp as shown in
Fig. 1.
D
Air compressor: Follow manufacturer’s recommen-
dations.
D
Object being sprayed: Follow your local code.
D
All solvent pails used when flushing or relieving
pressure, always hold a metal part of the gun firmly
to the side of a grounded metal pail, then trigger the
gun.
D
To maintain grounding continuity when flushing or
relieving pressure, always hold a metal part of the
spray gun firmly to the side of a grounded metal
pail, then trigger the spray gun.
To ground the pump:
1.
UL–Listed Pumps: Use a ground wire, connector,
and clamp. See Fig. 1. Loosen screw (X). Insert
one exposed end of a 12 ga (1.5 mm
2
) minimum
ground wire (Y) through the eye of the ground
terminal connector (W) and tighten screw (X)
securely. Connect the other end of the wire to a
true earth ground. Order Part No. 237569 Ground
Wire and Clamp.
2.
Non UL–Listed Pumps: See Fig. 1. Remove the
ground screw (Z). Fasten the ground connector
(W) onto the pump with the ground screw (Z) and
tighten securely. Loosen screw (X). Insert one
exposed end of a 12 ga (1.5 mm
2
) minimum
ground wire (Y) through the eye of the ground
terminal connector (W) and tighten screw (X)
securely. Connect the other end of the wire to a
true earth ground. Order Part No. 222011 Ground
Connector/Wire and Clamp.

Operation
Pressure Relief Procedure
WARNING
INJECTION HAZARD
The system pressure must be manually
relieved to prevent the system from
starting or spraying accidentally. Fluid
under high pressure can be injected through the
skin and cause serious injury. To reduce the risk of
an injury from injection, splashing fluid, or moving
parts, follow the Pressure Relief Procedure
whenever you:
D
are instructed to relieve the pressure,
D
stop spraying/dispensing,
D
check or service any of the system equipment,
D
or install or clean the spray tips or nozzles.
1.
Shut off the air to the pump.
2.
Close the bleed-type master air valve (required in
your system).
3.
Hold a metal part of the gun to the side of a
grounded metal pail and trigger the gun to relieve
pressure.
4.
Open the fluid drain valve (required in your sys-
tem), having a container ready to catch the drain-
age.
5.
Leave the drain valve open until you are ready to
spray/dispense again.
If you suspect that the spray tip/nozzle or hose is
clogged or that fluid pressure is not fully relieved after
following the steps above, very slowly loosen the tip
guard retaining nut or hose end coupling and relieve
pressure gradually. Clear the tip or hose obstruction.
