Grounding the System

WARNING

FIRE AND EXPLOSION HAZARD
Before operating the fluid pressure
regulator, ground the system as
explained below.

Pump:  Use a ground wire and clamp.  Loosen the
grounding lug locknut (W) and washer (X). Insert one
end of a 1.5 mm

@

 (12 ga) minimum ground wire (Y)

into the slot in lug (Z) and tighten the locknut securely.
Connect the other end of the wire to a true earth
ground. Order Part 237569 Ground Wire and Clamp.

Air and fluid hoses:  Use only electrically conductive
hoses.

Heaters, if used:  See the heater instruction manual.

Air compressor:  Follow manufacturer’s
recommendations.

Spray gun:  Ground through connection to a properly
grounded fluid hose and pump.

Fluid supply container:  Follow your local code.

Object being sprayed:  Follow your local code.

Solvent pails used when flushing:  Follow your local
code. Use only metal pails, which are conductive,
placed on a grounded surface. Do not place the pail on
a nonconductive surface, such as paper or cardboard,
which interrupts the grounding continuity.

To maintain grounding continuity when flushing or
relieving pressure
, hold a metal part of the spray gun
firmly to the side of a grounded metal pail, then trigger
the gun.

Pressure Relief Procedure

WARNING

SKIN 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
