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.
1. Pump: See F
IG. 2. Verify that the ground screw (GS)
is attached and tightened securely to the air motor.
Connect the other end of the ground wire (R) to a
true earth ground.
2. Pump fluid hoses: use only electrically conductive
fluid hoses Check electrical resistance of hoses. If
total resistance to ground exceeds 25 megohms,
replace hose immediately.
3. Viscon HP Heater: refer to the heater manual,
supplied.
4. Air compressor: follow manufacturer's recommen-
dations.
5. Spray gun: ground through connection to a properly
grounded fluid hose and pump.
6. Fluid supply container: follow your local code.
7. Object being sprayed: follow your local code.
8. Solvent pails used when flushing: follow your local
code. Use only metal pails, which are conductive,
placed on a grounded surface. Do not place the pail
on a nonconductive surface, such as paper or card-
board, which interrupts the grounding continuity.
9. To maintain grounding continuity when flushing or
relieving pressure, hold a metal part of the spray
gun firmly to the side of a grounded metal pail, then
trigger the gun.
