Grounding

Pump: See F

IG

. 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.
