Installation
Grounding
Proper grounding is an essential part of maintaining a
safe system.
To reduce the risk of static sparking, ground the pump.
Check your local electrical code for detailed grounding
instructions for your area and type of equipment. Be
sure to ground all of this equipment:
1. Pump: use a ground wire and clamp as instructed
in your pump instruction manual.
2. Fluid hoses: Use only grounded hoses with a maximum of 500 feet (150 m) combined hose length to
ensure grounding continuity.
3. Spray gun, manifold, or dispensing valve: obtain
grounding through connection to a properly
grounded connection to a properly grounded fluid
hose and sprayer.
6. All solvent pails used when flushing, according to
local code. Use only metal pails, which are conductive. Do not place the pail on a nonconductive
surface, such as paper or cardboard, which
interrupts the grounding continuity.
7. To maintain grounding continuity when flushing orrelieving pressure, always hold a metal part of the
gun firmly to the side of a grounded metal pail,
then trigger the gun.
Installation (See Fig. 1)
For assistance in setting up a plural component system, contact your Graco distributor. This will help assure that you select the proper type and size equipment for your job.
Use the spacer (40), screws (37), nuts (38) and lockwashers (39) provided to mount the manifold.
Connect the supply lines from your pump to the manifold inlets (R & Q).
4. Object being sprayed: according to local code.
5. Supply Containers: according to local code.

Operation
Start-up
The mixer manifold was tested in oil, which was left in
to protect the manifold. Before operating, thoroughly
flush the manifold to prevent contamination of the
fluids.
Flushing Procedure
CAUTION
Be sure to label all fluid path parts “component A” or
“component B” when disassembling them. Doing so
prevents interchanging A and B parts during reassembly, which will contaminate the materials and the
fluid path through the equipment.
Color-coded chemically resistant tape may be used
to label the parts. Use blue for component A, green
for component B, white for solvent, and red for mixed
material.
Place the handle in the UP, or closed, position. Turn on
the solvent supply pump. Open one of the solvent
valves. Release the spray gun safety latch. Hold the
gun firmly to the side of a grounded metal pail, then
trigger the gun to flush. Flush until all contaminants
and oil are removed. Release the trigger, engage the
safety latch, and close the solvent valve. Repeat for
the other solvent valve.
Any ratio check valves on the manifold output side
must be flushed. Place a container under both valves
to catch the waste solvent. Flush the valves after triggering the gun, one side at a time.
Solvent may channel through viscous fluids and leave
a coating of mixed fluid on the inner tube of your hose.
Fig 2 shows the handle in the UP, or closed, position and the
right solvent valve open with solvent flowing through the
right fluid chamber and out through the mixing chamber.

Be sure all fluid is thoroughly flushed from the hose
after each use.
Disassemble all other dispensing equipment, as necessary, and clean thoroughly.
CAUTION
To prevent fluid from setting up in the dispensing
equipment, flush the system frequently. Be sure
there is adequate solvent in the solvent supply
before starting to spray.
Dispensing
To dispense the resin and hardener, turn on the supply
pumps. Then push the handle forward (DOWN) to the
open position. To stop the flow, move the handle to the
UP or closed position.

Pressure Relief Procedure
WARNING
INJECTION HAZARD
The system pressure must be manually
relieved to prevent the system from
starting or spraying accidentally. Fluid
under high pressure can be injected through the
skin and cause serious injury. To reduce the risk of
an injury from injection, splashing fluid, or moving
parts, follow the Pressure Relief Procedure
whenever you:
D are instructed to relieve the pressure,
D stop spraying,
D check or service any of the system equipment,
D or install or clean the spray tip.
Troubleshooting
1. Close the mixer fluid valves.

pressure.
5. Engage the gun safety latch
6. Open any drain valves, and leave them open until
you are ready to spray again.
7. If fluid has hardened in the hose or mixer, close
the fluid valve, shut off the fluid and solvent
pumps, and slowly loosen the fluid inlet hose(s) to
relieve pressure, then remove the dispensing
hose.
1. Relieve the pressure before you check or service

Manifold Repair (See Page 10. )
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 8.
Note: Repair kits are available for the manifold. Parts
included in the kits are indicated with a †, for example
(9†) See page 11.
1. Relieve the Pressure.
2. Remove the twelve socket-head screws (2) to
separate the two valve housings (8) from the
manifold housing (7). Remove all parts from the
housings.
3. Clean all parts thoroughly in a compatible solvent.
Use a soft bristle brush to clean the manifold
passageways.
4. Install the two check valve assemblies (9†) and
valve seats (6†) in the manifold housing (7).
5. Install the needle valve (12), back-up ring (4**),
and seal (3†) in each of the valve housings (8).
7. Tighten the needle valve slightly, so that the
tapered end centers in the seat (6) and holds its
position.
8. Turn the six socket screws (2) oppositely and
evenly to 60–70 in-lbs (6.7–7.9 NSm). Back off the
needle valve (12) slightly.
9. Repeat step 8 as the torque will relax.
CAUTION
Be sure to tighten the six socket screws (2) evenly.
The upper four screws, which surround the needle
valve assembly (12), are critical in ensuring that the
needle seats properly. If the bottom two screws are
over-tightened, they will throw off the alignment.
10. Repeat the procedure from step 9 on the other
valve housing (8).
Ball Valve Repair (See Page 10.)
Note: Repair Kit 217560 is available for the ball valves.
Parts included in the kit are indicated with an asterisk,
for example (18*). See page 11.
6. Install six socket-head screws (2) through one
valve housing (8) and into the manifold housing
(7), so the distance between the housings is
0.060 in. (1.5 mm).
When reassembling a ball valve (13 or 24), install the
ball (18* or 29*) so that the round hole aligns with the
main passageway of the valve body and the square
hole aligns with the stem (21 or 32) passageway.
