Installation
General Information
NOTE: Reference numbers and letters in parentheses
in the text refer to the callouts in the figures and the
parts drawing.
NOTE: Always use Genuine Graco Parts and Acces-
sories, available from your Graco distributor. If you
supply your own accessories, be sure they are ade-
quately sized and pressure rated for your system.
Fig. 2 is only a guide for selecting and installing sys-
tem components and accessories. Contact your Graco
distributor for assistance in designing a system to suit
your particular needs.
Grounding
WARNING
FIRE AND EXPLOSION HAZARD
Before operating the pump, ground the
system as explained below. Also read
the section FIRE AND EXPLOSION
HAZARD on page 3.
1. Pump: To ground the pump, loosen the grounding
lug locknut (A) and washer (B). Insert one end of a
12 gal (1.5 mm2) minimum ground wire (D) into the
slot in lug (C) and tighten locknut securely. See
Fig. 1. Connect the other end of the wire to a true
earth ground. Check your local code.
TI1809A
Fig. 1
A
B
D
C
2. Air and fluid hoses: use only grounded hoses with
a maximum of 500 ft (150 m) combined hose
length to ensure grounding continuity.
3. Air compressor: follow manufacturer’s recommen-
dations.
4. Spray gun or dispensing valve: obtain grounding
through connection to a properly grounded fluid
hose and pump.
5. Object being sprayed: follow your local code.
6. 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
cardboard, which interrupts the grounding continu-
ity.
7. To maintain grounding continuity when flushing or
relieving pressure, hold a metal part of the gun/
valve firmly to the side of a grounded metal pail,
then trigger the gun/valve.

Installation
Mounting the Pump
Mount the pump to suit the type of installation planned.
The pump dimensions and mounting hole layout are
shown on page 16.
System Accessories
Refer to the Installation drawing and the information on
the following pages for assistance setting up your
system.
NOTE: To ensure maximum pump performance, be
sure that any accessory used is properly sized to meet
your system’s requirements.
Your system should include an air line filter (J) to
remove harmful dirt and moisture from your com-
pressed air supply. On the air line (E), each pump
should have a bleed–type master air valve (G), an air
regulator (F) and shutoff valve (O), and an air line oiler
(K) which must be installed downstream from the air
regulator. See Fig. 2.
WARNING
Two accessories, the bleed–type master air valve
(G), and the fluid drain valve (R), are required for
your system to reduce the risk of serious bodily
injury from moving parts or injection when shutting
off the pump.
The bleed–type air valve relieves trapped air
between the valve and the pump, after the pump is
shut off. Trapped air can cause the pump to cycle
unexpectedly and result in serious bodily injury if
you are adjusting or repairing the pump.
The fluid drain valve helps relieve fluid pressure in
the displacement pump, hose, and gun/dispensing
valve when shutting off the pump. Triggering the
gun/dispensing valve to relieve pressure may not
be sufficient, especially if there is a clog in the
hose, gun/dispensing valve, and/or tip/nozzle.
Connecting the Hoses
Connect a grounded air supply hose (E) to the 1/2
npt(f) air inlet or the air regulator. Connect a grounded
fluid dispensing hose (L) to the 1 in. npt fluid outlet,
using a suitable adapter. For more flexible gun move-
ment, use a shorter whip hose (grounded) (M) be-
tween the main fluid hose and the gun/valve.

Operation
Pressure Relief Procedure
WARNING
FLUID INJECTION HAZARD
The system pressure must be manually relieved to
prevent the system from starting or spraying acci-
dentally. To reduce the risk of an injury from acci-
dental spray from the gun, splashing fluid, or
moving parts, follow the Pressure Relief Proce-
dure whenever you:
Dare instructed to relieve the pressure,
Dstop spraying,
Dcheck or service any of the system equipment,
Dor install or clean the spray nozzle.
1. Shut off the air supply to the pump.
2. Close the bleed-type master air valve (required in
your system).
3. Hold a metal part of the gun firmly to the side of a
grounded metal pail, and trigger the gun to relieve
pressure.
4. Open the drain valve (required in your system),
having a container ready to catch the drainage.
5. Leave the drain valve open until you are ready to
spray again.
If you suspect that the spray nozzle or hose is com-
pletely clogged, or that pressure has not been fully
relieved after following the steps above, very slowly
loosen the nozzle retaining ring or hose end coupling
and relieve pressure gradually, then loosen completely.
Now clear the nozzle or hose.
Flush Pump Before Using
Pumps are tested with lightweight oil which is left in to
protect the pump parts. To prevent contamination of
fluids, flush the pump with a compatible solvent before
using. If the pump will supply a circulating system,
circulate the solvent until the system is thoroughly
flushed.
WARNING
Be sure your entire system is properly grounded
before flushing. Refer to Fire or Explosion Haz-
ard on page 3. Relieve pressure, remove the tip
from the gun, then hold a metal part of the gun
firmly to the side of a grounded metal pail, and use
the lowest possible pressure to flush.

306746 9
Operation
Starting and Adjusting the Pump
Fill the wet–cup (25) half full with Graco Throat Seal
Liquid (TSL). With the drain valve and bleeder valve
closed, and the gun/valve safety disengaged, trigger
the gun/valve and slowly open the air supply valve until
the pump starts. If fluid does not flow from triggered
gun/valve, open the bleeder valve (12) slightly. See
Fig. 3. When fluid appears, close bleeder valve.
WARNING
Keep your hand and fingers away from the priming
piston and fluid intake valve (R) to reduce the risk
of serious bodily injury, including amputation.
With the pump and lines primed, and with adequate air
pressure and volume supplied, the pump will start and
stop as the spray gun/valve is triggered and released.
In a circulating system, it will run continuously and
speed up or slow down as supply demands until air
supply is shut off.
Use an adequately sized air regulator (F) to control
pump speed and fluid pressure. See the Installation
drawing on page 7. Always use the lowest pressure
necessary to give you the results you want.
Never exceed the maximum air pressure to the pump
(see Technical Data on page 17). TI1810A

Maintenance
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 8.
Keep the wet–cup (25) filled with Graco Throat Seal
Liquid (TSL). See Fig. 3. Check tightness of packing
nut (36 or 60) weekly. The packing nut should be tight
enough to prevent leakage, but no tighter. Follow the
Pressure Relief Procedure on page 8 before adjust-
ing the packing nut.
Never allow the pump to run dry of fluid being pumped.
A dry pump will quickly accelerate to a high speed,
possibly damaging itself. If your pump accelerates
quickly, or is running too fast, stop it immediately and
check the fluid supply. If the supply container is empty
and air has been pumped into lines, prime pump and
lines with fluid, or flush and leave filled with compatible
solvent. Eliminate all air from fluid system.
For overnight shutdown, follow the Pressure Relief
Procedure on page 8. Always stop the pump at the
bottom of its stroke to keep fluid from drying on the
exposed displacement rod. Always flush the pump
before the fluid dries on the rod. If the pump is to be
stored, and you are pumping water–based fluids, first
flush with water, then with mineral spirits to protect the
pump parts.

306746 11
Troubleshooting
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 8.
Before You Start
DTo reduce downtime, be sure you have all neces-
sary repair parts available. Recommended spare
parts are listed in the Parts List on page 14 with an
asterisk (*).
DPacking repair kits are available for both the 24:1
and 48:1 pumps (see Parts List on page 14). If you
have a repair kit, use all the new parts for the best
results. Parts included in the repair kits are marked
with a double asterisk (e.g., 28**).
DWhenever you replace the packings, also replace
the glands and bearing.
DWhen cleaning parts, use a compatible solvent.
Inspect parts for wear or damage and replace as
necessary. Scoring or irregular surfaces on the
booster rod (35) or the displacement rod (33 or 59)
causes premature packing wear and leaking. Check
these parts by rubbing a finger on the surface or
holding them up to the light at a slight angle.
DUse light, water–proof grease whenever grease is
mentioned.
DCheck all possible problems and solutions before
disassembling pump.
Problem Cause Solution

Graco Standard Warranty
Graco warrants all equipment manufactured by Graco and bearing its name to be free from defects in material and workmanship on the
date of sale by an authorized Graco distributor to the original purchaser for use. With the exception of any special, extended, or limited
warranty published by Graco, Graco will, for a period of twelve months from the date of sale, repair or replace any part of the equipment
determined by Graco to be defective. This warranty applies only when the equipment is installed, operated and maintained in accor-
dance with Graco’s written recommendations.
This warranty does not cover, and Graco shall not be liable for general wear and tear, or any malfunction, damage or wear caused by
faulty installation, misapplication, abrasion, corrosion, inadequate or improper maintenance, negligence, accident, tampering, or sub-
stitution of non–Graco component parts. Nor shall Graco be liable for malfunction, damage or wear caused by the incompatibility of
Graco equipment with structures, accessories, equipment or materials not supplied by Graco, or the improper design, manufacture,
installation, operation or maintenance of structures, accessories, equipment or materials not supplied by Graco.
This warranty is conditioned upon the prepaid return of the equipment claimed to be defective to an authorized Graco distributor for
verification of the claimed defect. If the claimed defect is verified, Graco will repair or replace free of charge any defective parts. The
equipment will be returned to the original purchaser transportation prepaid. If inspection of the equipment does not disclose any defect
in material or workmanship, repairs will be made at a reasonable charge, which charges may include the costs of parts, labor, and
transportation.
THIS WARRANTY IS EXCLUSIVE, AND IS IN LIEU OF ANY OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT
NOT LIMITED TO WARRANTY OF MERCHANTABILITY OR WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE.
Graco’s sole obligation and buyer’s sole remedy for any breach of warranty shall be as set forth above. The buyer agrees that no other
remedy (including, but not limited to, incidental or consequential damages for lost profits, lost sales, injury to person or property, or any
other incidental or consequential loss) shall be available. Any action for breach of warranty must be brought within two (2) years of the
date of sale.

purchaser with reasonable assistance in making any claim for breach of these warranties.
In no event will Graco be liable for indirect, incidental, special or consequential damages resulting from Graco supplying equipment
