Grounding
Proper grounding is essential to maintaining a safe sys-
tem.
To reduce the risk of static sparking, ground the pump,
bead spray gun, paint spray gun and all other system
equipment.
1. Pump: Use a ground wire and clamp.
2. Air compressors and hydraulic power supplies:
Follow manufacturer's recommendations.
3. Air and fluid hoses connected to the pump: Use
only grounded hoses with a maximum of 500 feet
(150 m) combined hose length to ensure grounding
continuity.
4. Dispensing valve: Obtain grounding through con-
nection to a properly grounded fluid hose, frame,
and pump.
5. Fluid supply container: According to local code.
6. All solvent pails used when flushing: Ground
according to local code. Use only metal pails, which
are conductive. Do not place the pail on a non con-
ductive surface, such as paper or cardboard, which
interrupts the grounding continuity.
