Grounding
WARNING
FIRE AND EXPLOSION HAZARD
Before operating the pump, ground the
system as explained below. Also read
the section FIRE AND EXPLOSION
HAZARD on page 3.
1. Pump: use a ground wire and clamp as shown in
your separate pump manual.
2. Air or hydraulic hoses: use only electrically con-
ductive hoses.
3. Fluid hoses: use only electrically conductive fluid
hoses.
4. Air compressor or hydraulic supply: follow the
manufacturer’s recommendations.
5. Spray gun: ground by connecting the gun 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
cardboard, which interrupts the grounding continu-
ity.
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.
