Grounding
Pump: See F
. 4. Verify that the ground screw (GS) is
attached and tightened securely to the air motor. Con-
nect the other end of the ground wire (S) to a true earth
ground.
Air and fluid hoses: Static electricity may build up
when fluids flow through pumps, hoses, and sprayers.
At least one hose must be electrically conductive, with a
maximum of 500 ft. (150 m) combined hose length to
ensure grounding continuity. Check electrical resistance
of hose. If total resistance to ground exceeds 25 meg-
ohms, replace hose immediately.
Air compressor: follow manufacturer’s recommenda-
tions.
Spray gun / Dispense valve:
Ground the spray gun
through connection to a Graco-approved grounded fluid
hose.
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/dispense valve firmly to the side of a grounded
metal pail, then trigger the gun/valve.
Mount the Pump
Mount the pump directly to the wall (order Wall Mounting
Kit, page 22) or to a Graco cart (order Cart Mounting Kit
24E879). Pump dimensions are shown on page 27.
Wall-Mounted Pumps
1.
Be sure the wall can support the weight of the
pump, bracket, hoses and accessories, as well as
the stress caused during operation.
2.
Position the wall bracket about 1.2-1.5 m (4-5 ft)
above the floor. For ease of operation and service,
make sure the pump air inlet, fluid inlet, and fluid
outlet ports are easily accessible.
3.
Using the wall bracket as a template, drill 10 mm
(0.4 in.) mounting holes in the wall. Wall mounting
dimensions are shown on page 28.
4.
Attach the bracket to the wall. Use 9 mm (3/8 in.)
screws that are long enough to keep the pump from
vibrating during operation.
NOTE: Be sure the pump is level.
Cart-Mounted Pumps
Kit 24E885 is available if you plan to bolt your cart to the
floor. It includes two spacers that keep the legs stable.
Bolts not included.
Air and Fluid Hoses
Be sure all air hoses (N) and fluid hoses (M) are prop-
erly sized and pressure rated for your system. See F
IG
.
3. Use only electrically conductive fluid hoses.
The equipment must be grounded. Grounding
reduces the risk of static and electric shock by pro-
viding an escape wire for the electrical current due to
static build up or in the event of a short circuit.
