page 4.

To reduce the risk of static sparking, ground the pump
and all other components used or located in the dis-
pensing area. Check your local electrical code for
detailed instructions for your area and type of equip-
ment and be sure to ground all of these components.

D

Pump:

  use a ground wire and clamp as instructed

in your separate pump instruction manual.

D

Air compressors and hydraulic power supplies:

ground according to the manufacturer’s recommen-
dations.

D

Air and fluid hoses:

  use only electrically conductive

hoses with a maximum of 500 feet (150 m) com-
bined hose length to ensure grounding continuity.

D

Dispensing valve:

 obtain grounding through con-

nection to a properly grounded fluid hose and
pump.

D

Fluid supply container:

  according to local code.

D

All solvent pails 

used when flushing, according to

tive. Do not place the pail on a non-conductive
surface, such as paper or cardboard, which inter-
rupts grounding continuity.
