Installation
Installation
Grounding
The equipment must be grounded. Grounding
reduces the risk of static and electric shock by
providinganescapewirefortheelectricalcurrent
duetostaticbuilduporintheeventofashort
circuit.
Pump: Connect a ground wire (Graco PN 238909)
to the ground screw on the bottom cover of the air
motor, under the shield. 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.
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.
Mounting
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.
To avoid serious injury, check the torque on the lift
ring (19) and nut (18) before using the lift ring to lift
the pump. Torque to 30–36 ft-lb (41–49 N•m).
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.
Accessories are available from Graco. Make certain
all accessories are sized and pressure rated to meet
your system requirements.
ig 1 is only a guide for selecting and installing
system components and accessories. Contact your
Graco distributor for assistance in designing a system
to suit your particular needs.
Install a bleed-type master air valve (G) close to the
pump air inlet (D), to relieve air trapped between it
and the air motor.
Install an air filter/regulator ( ) in the pump air
line, upstream from the bleed valve, to control
air inlet pressure and to remove harmful dirt and
contaminants from your compressed air supply.
Install a pump runaway valve (S) in the pump air line
to shut off air to the air motor automatically if the
pump starts to run too fast.
Install another bleed-type master air valve (G)
upstream from all air line accessories and use it to
isolate the accessories during cleaning and repair.
On the air drop to the dispense valve (K), install an
air regulator (M) to control air pressure to the valve.
Install a bleed valve (G) to use as a shutoff when
servicing the dispense valve.

NOTICE
Do not expose the air motor to temperatures
higher than 120° (49°C) or the immersed fluid
pump to temperatures higher than 250° (121°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.
Flush Before First Use
The sanitary pump was assembled using sanitary
lubricant on moving parts and was tested in
water. lush the pump thoroughly with an
appropriate cleaning solution or disassemble and
sanitize the parts before using the pump. See
lushing Procedure, page 9 . Check national, state,
and local codes for specific limitations.
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
circulatingsystem,thepumpoperatesuntiltheair
supply is turned off.
NOTICE
Neverallowthepumptorundryoffluid. Adry
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
thepumpandlineswithfluid.Besuretoeliminateall
air from the system.
Pump Shut Down
ollow 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.
