Split Manifold Kits

2 308439E
Installation
The Split Manifold Kit enables you to convert the Husky
307 Pump to a dual fluid inlet manifold, dual fluid outlet
manifold, or both. See Figs. 1, 2, and 3 for some
applications. To install the kit, see page 3.
NOTE: To convert both the inlet and the outlet manifold,
two kits are required.

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.
Fig. 2 _________________________________________
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.

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.

Installation
Installation Procedure
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).
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.
5. Install the split manifolds (1). Apply thread lubricant
to the screws and torque to 50-60 in-lb (5.6-6.8 N•m).
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.
8. Prolonged exposure to UV radiation will degrade
natural polypropylene components of the pumps. To
prevent potential injury or equipment damage, do not
expose pump or the plastic components to direct
sunlight for prolonged periods.
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.
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.
