1. Pump: one end of the ground wire (30) is already
connected to the air motor grounding lug. Connect
the clamp end of the ground wire to a true earth
ground.
2. Air and fluid hoses: use only grounded hoses with
a maximum of 500 ft. (150 m) combined hose
length to ensure grounding continuity.
3. Air compressor: according to manufacturer’s
recommendations.
4. Spray gun: grounding is obtained through connec-
tion to properly grounded fluid hoses and pump.
5. Fluid supply container: according to local code.
6. All solvent pails used when flushing, according to
local code. Use only metal pails, which are con-
ductive. Do not place the pail on a non-conductive
surface, such as paper or cardboard, which inter-
rupts the grounding continuity.
