NOTE: Reference letters and numbers in parentheses in the text refer to callouts in the figures and drawings.
Grounding
Ground all equipment:
• Pump: Use a ground wire and clamp as shown in
F
IG
. 2.
a. Remove the ground screw (Z) and insert
through the eye of the ring terminal at end of
ground wire (Y).
b. Fasten the ground screw back onto the pump
and tighten securely.
NOTE: To order a ground wire and clamp, order Graco
Part No. 222011.
• Air and fluid hoses: Use only electrically conductive
hoses.
• Air compressor: Follow manufacturer’s recommen-
dations.
• Dispensing valve: Ground through connection to a
properly grounded fluid hose and pump.
• Object being dispensed to: Follow your local code.
• 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.
• To maintain grounding continuity when flushing or
relieving pressure,
hold a metal part of the dispens-
ing valve firmly to the side of a grounded metal pail,
then trigger the dispense valve.
Installation Guidelines
Reference letters found in the following instructions,
refer to Typical Installation diagram provided on page
6.
• A ball valve must be installed upstream of the regu-
lator (G).
• The fluid outlet line (A), fluid inlet line (L) and air
inlet line (M) must be flexible (such as a hose).
NOTE: To prevent damage to the pump, remove sedi-
ment from the bottom of the container before installing a
pump on an existing container.
To reduce the risk of static sparking, ground the pump
and all other components used or located in the
dispensing area. Check your local electrical code for
detailed instructions for your area and type of
equipment.
