Installation
Installation
Grounding
The equipment must be grounded. Grounding
reduces the risk of static and electric shock by
providing an escape wire for the electrical current
due to static build up or in the event of a short circuit.
Pump: Connect a ground wire (Graco PN 238909) to
the ground screw on the bottom cover of the air motor,
under the shroud. Connect the other end of the ground
wire to a true earth ground.
Air and fluid hoses: use only electrically conductive
hoses with a maximum of 500 ft. (150 m) combined
hose length to ensure grounding continuity. Check electrical resistance of hoses. If total resistance to ground
exceeds 25 megohms, replace hose immediately.
Air compressors: follow manufacturer’s recommendations.
Dispense valve: ground through connection to a properly grounded fluid hose and pump.
Material supply container: follow local code.
Mounting
To avoid injury from a falling pump, check the torque
on the lift ring (16) and nut (15) before using the lift
ring to lift the pump. Torque to 30-36 ft-lb
(41-49 N•m).
Mount the pump on a surface than can support the
weight of the pump and accessories, as well as the
stress caused during operation. Do not use air or fluid
lines to support the pump.
Setup
To avoid contaminating the fluid, pipe the exhaust air
to vent outside of the fluid product area, away from
people, animals, or food-handling areas.
NOTE: Reference numbers and letters in parentheses in
the text refer to the callouts in the figures and the parts
drawings.
Container(s) that receive material: follow local code.
Solvent pails used when flushing: follow local code.
Use only conductive metal pails, placed on a grounded
surface. Do not place the pail on a nonconductive surface, such as paper or cardboard, which interrupts
grounding continuity.
To maintain grounding continuity when flushing or
relieving pressure: hold metal part of the dispense
valve firmly to the side of a grounded metal pail, then
trigger the valve.

NOTICE
Do not expose the air motor to temperatures higher
than 120°F (49°C) or the immersed fluid pump to temperatures higher than 160°F (71°C). Excessive temperatures may damage the pump packings and seals.
Pressure Relief Procedure
Trapped air can cause the pump to cycle
unexpectedly, which could result in serious injury from
injection, splashing, or moving parts. Relieve pressure
when you stop pumping and before cleaning,
checking, or servicing equipment.
1. Shut off the air supply to the pump.
2. Close the bleed-type master air valve (required in
system).
3. Open the fluid ball valve and/or dispensing valve to
relieve fluid pressure.
Adjusting the Pump Speed and Pressure
Set pressure regulator to 0 psi. Open the bleed-type
master air valve. Adjust the pump air regulator until the
pump is running smoothly.
Allow the pump to cycle slowly until all air is pushed out
of the lines (the fluid will flow in a steady stream from the
fluid outlet) and the pump is primed.
With the air supply turned on, the pump will start when
the dispensing valve is opened and stall against pressure when the valve is closed. In a circulating system,
the pump operates until the air supply is turned off.
NOTICE
Never allow the pump to run dry of fluid. A dry pump will
accelerate to a high speed, possibly damaging itself.
If the pump accelerates quickly, or is running too fast,
stop the pump immediately and check the fluid supply. If
the supply is empty and air has been pumped into the
lines, refill the container and prime the pump and lines
with fluid. Be sure to eliminate all air from the system.
Flush Before First Use
The sanitary pump was assembled using sanitary lubricant on moving parts and was tested in water. Flush the
pump thoroughly with an appropriate cleaning solution,
and disassemble and sanitize the parts before using the
pump. See Flushing Procedure, page 9. Check
national, state, and local codes for specific limitations.
Pump Shutdown
Follow the Pressure Relief Procedure, page 8. Always
stop the pump at the bottom of its stroke to prevent fluid
from drying on the displacement rod. (The air motor will
exhaust at the bottom and top of the stroke.)
