manifolds.
System Explanation
In this installation, fluid is drawn from the supply container into one of the manifold inlets.
With the fluid needle valve (N) closed, the fluid
is pumped through side A and out to the tray.
Opening the air side needle valve (P) draws air
into the fluid return line so less fluid is returned
to the pump (side B) than is supplied to the
tray.
To circulate the fluid, close valves P and N.
To lower the fluid level in the tray, close valve
P and open valve N.
To raise the fluid level in the tray, close valve N
and open valve P.
This is a basic system. Additional equipment
such as solenoids and float valves can be used
for automated systems. See your Graco representative for details.

TWO FLUIDS TO TWO DESTINATIONS
Uses dual inlet and dual outlet manifolds.
System Explanation
Supplies two fluids, such as two colors of ink, to two
separate destinations. Use in installations where
surging does not cause a problem.

1:1 MIX RATIO (approximate)
Uses dual inlet and single outlet manifolds.
System Explanation
Mixes two fluids, such as antifreeze and water, in an
approximate 1:1 ratio. Minimum fluid output should
be in increments of 3 quarts to ensure an approximate 1:1 ratio. Lower output quantities may result in
an unequal mix ratio.

Installation Procedure
WARNING
Pressure Relief Procedure
To reduce the risk of serious injury, including
splashing fluid or solvent in the eyes or on the skin,
follow this procedure before installing this kit.
1. Shut off the air to the pump.
4. Remove the outer o-ring from each cover (C) and
replace them with the new o-rings (3) from the kit.
See Fig. 4.
NOTE: Acetal pumps use screws (A) and nuts (B) to
secure the manifolds, as shown in Fig. 4. Polypropylene pumps use nuts, washers, and tie rods; refer to
manual 308553.
2. Open the dispensing valve, is used.
3. Open the fluid drain valve to relieve all fluid
pressure, having a container ready to catch the
drainage.
1. Follow the Pressure Relief Procedure above.
2. Disconnect the fluid inlet and/or outlet line from the
pump manifolds.
3. Remove the fluid inlet and/or fluid outlet manifold,
as explained in the pump manual 308553. Keep
the attaching hardware (A, B) and the feet (D).
5. Install the split manifolds (1). Apply thread lubricant to the screws and torque to 50–60 in-lb
(5.6–6.8 NSm). Do not over-torque. See Torque
Sequence, page 5.
6. The warning label (2) supplied in the kit replaces
the one on the standard outlet manifold removed in
step 3. First, clean the pump cover (C) with a compatible solvent so the label will adhere permanently, then install the label as shown.
7. Connect the fluid inlet and/or outlet lines to the
manifolds securely, and return the pump to service.
