Grounding
Pump: Connect a ground wire (Graco PN 238909) to 
the ground screw on the bottom cover of the air motor, 
under the shield. Connect the other end of the ground 
wire to a true earth ground.
Air and fluid hoses: use only electrically conductive 
hoses with a maximum of 500 ft. (150 m) combined 
hose length to ensure grounding continuity. Check elec-
trical resistance of hoses. If total resistance to ground 
exceeds 25 megohms, replace hose immediately.
Air compressors: follow manufacturer’s recommenda-
tions.
Dispense valve: ground through connection to a prop-
erly grounded fluid hose and pump.
Material supply container: follow local code.
Container(s) that receive material: 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 dispense 
valve firmly to the side of a grounded metal pail, then 
trigger the valve.
Location
Position the ram so the air controls are easily accessi-
ble. Ensure that there is sufficient overhead clearance 
when the ram is fully raised. See Repair, page 20.
Position the ram in an area with adequate access for 
servicing and cleaning the equipment and adjacent 
areas to maintain the required level of hygiene. Locate 
equipment away from sources of air currents, dust, or 
liquids derived from leakage, condensation, or aerosols.
Using the holes in the ram base as a guide, drill holes 
for 1/2 in. (13 mm) anchors.
Check that the ram base is level in all directions. If nec-
essary, level the base using metal shims. Secure the 
base to the floor using 1/2 in. (13 mm) anchors that are 
long enough to prevent the ram from tipping.
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.
