Installation
If using a flammable gas to drive the motor, to reduce
the risk of fire or explosion, route the exhaust away
from all sources of ignition. See Route Exhaust to
Remote Location on page 9.
NOTE: A small amount of the exhaust is not recover-
able, and will vent to atmosphere at the pump. However, a 100% Exhaust Capture Kit, B32651, is
available.
To reduce the risk of injury from ejected ice, do not
operate the motor without a plumbed exhaust line or
muffler installed.
Installation must comply with all local codes and regulations.
Grounding
The equipment must be grounded to reduce the risk
of static sparking. Static sparking can cause fumes to
ignite or explode. Grounding provides an escape wire
for the electric current.

Installation
Connect Pneumatic Supply
1. Install the pneumatic regulator (E) and gauge to
control the inlet pressure. See Models on page 3 for
your model’s maximum pneumatic pressure.
NOTE: If less than 100 psi supply pressure is used, the
pump’s maximum output pressure will be decreased
proportionally.
Minimum Pneumatic Pressure can be found by first finding the table that corresponds to the plunger size (see
Minimum Pneumatic Pressures by Fluid Plunger
Size and Outlet Pressures on page 10). Next, using
the column that corresponds to the pneumatic motor
size, find the row equal to or slightly greater than the
outlet pressure of the pump. The value is the Minimum
Pneumatic Pressure required to achieve the fluid outlet
pressure.
2. Install a pneumatic line filter (C) to keep debris from
affecting pump performance and to increase pump
life.
NOTE: Keep the needle valve (B) closed at this point to
keep the pump from operating without fluid, which minimizes seal wear.
Connect Chemical Outlet
1. Connect a fluid line from the pump outlet port (M) to
the injection point.
2. Install a fluid pressure relief valve (J) on the outlet
side of the pump.
NOTE: A pressure relief valve is available from Graco
and can be connected back to the tank or directly to th e
inlet side of the pump. See Kits and Accessories on
page 35.
In the event of an injection line blockage, to reduce the
risk of skin injection and damage to the pump, ensure
the pressure relief valve is set at or below the maximum working pressure of the pump.
3. Set the pressure relief valve at or below the maximum working pressure of the pump.
3. Attach a pneumatic line to th e 1/ 4 in. fe ma le NPT
port on the needle valve (B).
Route Exhaust to Remote
Location
Replace the muffler (18) with a pneumatic line to route
exhaust to a remote location.
NOTICE
Due to the operational design of the pneumatic valve,
a small amount of the exhaust is not recoverable, a nd
will vent to atmosphere. However, a 100% Exhaust
Capture Kit, B32651, is available.

Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as skin injection and splashing
fluid, follow the Pressure Relief Procedure when
you stop dispensing and before cleaning, checking, or
servicing the equipment.
NOTE: Always discharge fluid into an approved container or location.
1. Shut off all fluid and pneumatic lines (A, K, & P)
using the two fluid shutoff valves (H) and the pneumatic needle valve (B).
2. Slowly loosen the fluid lines to (K & P) at the pump
outlets (L & M) to bleed off any residual pressure.
3. Disconnect the fluid lines (K & P) from pump outlets
(L & M).
Flush the Equipment
To avoid fire and explosion, always ground equipment
and waste container. To avoid static sparking and
injury from splashing, always flush at the lowest possible pressure.
• Flush with a fluid that is compatible with the fluid
being dispensed and the equipment wetted parts.
1. Follow the Pressure Relief Procedure.
2. Connect the inlet port to the flushing fluid supply
source.
3. Connect the outlet port to the waste reservoir.
4. Run the pump until the dispensed fluid is predominately flushing fluid.
5. Follow the Pressure Relief Procedure.
3A6831A 11
Operation
Prime the Pump
1. Verify all connections and fluid lines are tight.
NOTE: The pressure regulator (E) and inlet pneumatic
needle valve (B) both effect the pump cycle rate. After
inlet pressure is set, the needle valve can serve as a
speed control.
2. Adjust pneumatic regulator (E) to desired pressure.
3. Open bleed-type pn eu m at ic valv e (D) . Slowly turn
pump needle valve (B) counter-clockwise, increasing air/gas flow to the pump.
NOTICE
Pump runaway may occur if the needle valve (B) is
opened too far for pressure settings, causing damage
to the packing sets (102 and 107).
4. Keep the pump cycle rate less than 1 cycle every 3
seconds only while priming the pump.
Calibrate Chemical Dosage
1. Set the pump to an estimated setting of the flow
rate.
2. Follow the instructions provided with your calibration
gauge.
3. Adjust the cycle rate with the inlet pneumatic needle
valve (B) and/or the pressure regulator (E).
4. Repeat the steps 2 and 3 to verify your changes.
Repeat as necessary until the desired flow rate is
achieved.

Maintenance
Preventive Maintenance
Schedule
The operating conditions of your particular pump determines how often maintenance is required. Establish a
preventive maintenance schedule by recording when
and what kind of maintenance is needed, and then
determine a regular schedule for checking your pump.
Tighten Threaded Connections
Check that all threaded connections are tight at routine
intervals.
Tighten Packings
Maintenance
The packings included in your pump have the ability to
be adjusted to stop leaks that develop when the seals
are worn. If a leak develops in the pump’s fluid section,
tighten the packing nut clockwise by 1/16 of a turn, or
lower, until the leak is eliminated. The life of the packing
can be affected by over-tightening the packings. If the
packing nut needs to be tightened repeatedly after short
intervals, replace the packing.
Storage
If the pump is going to be stored for long periods, it is
recommended that the pump be flushed with a
light-weight oil or rust prohibiter to protect pump components. Store the pump with protective fluid inside whenever possible.
