2. Fluid hoses: use only the Graco heated hose,
which is electrically grounded.
3. Air and hydraulic hoses: use only electrically
conductive hoses.
4. Heater: by wiring to a grounded power supply. In a
mobile installation, be sure the truck or trailer is
grounded to a true earth ground.
5. Hydraulic power supply or air compressor: follow
manufacturer's recommendations.
6. Spray gun: ground through connection to a proper-
ly grounded fluid hose and pump.
7. Fluid supply container: follow your local code.
8. Object being sprayed: follow your local code.
9. 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.
10. 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.
