Grounding
8 3A0235G
Grounding
The equipment must be grounded. Grounding reduces
the risk of static and electric shock by providing an
escape wire for the electrical current due to static build
up or in the event of a short circuit.
Pump: follow instructions in separate feed pump man-
ual, supplied.
HFR: see operation manual.
Spray gun: see gun manual.
Fluid supply container: follow local code.
Object being sprayed: follow local code.
Solvent pails used when flushing: follow local code.
Use only conductive metal pails, placed on a grounded
surface. Do not place the pail on a nonconductive sur-
face, such as paper or cardboard, which interrupts
grounding continuity.
To maintain grounding continuity when flushing or
relieving pressure: hold metal part of the spray gun or
dispense valve firmly to the side of a grounded metal
pail, then trigger the gun or valve.

Installation
Feed Pump
1. Complete Setup instructions in pump manual
before installing in drum or pail.
a. For Riser Tube Kit 246419: Inspect bung o-ring
(309) and gasket (303) in place. If either is worn
or damaged, or if material shows signs of crys-
tallization, replace. See page 22.
b. If required, install desiccant dryer (Graco part
no. 247616 not included). Remove elbow and 2
in. bushing supplied with desiccant dryer (6).
Screw dryer 3/4 npt fitting into vent of moisture
sensitive drum.
Flush equipment only in a well-ventilated area. Do not
spray flammable fluids. Do not turn on heaters while
flushing with flammable solvents.
NOTICE
Lubricate bung o-ring with 217374 ISO Pump Oil
each time you change drums. This keeps air and
moisture from reacting with material and allows bung
adapter to rotate freely.
NOTICE
Tighten pump clamps and external fasteners before
first use. See pump manual.
