Installation Instructions

Pressure Relief Procedure

Follow this pressure relief procedure whenever you are instructed to relieve pressure or need to check or ser- vice equipment.

1.Turn off power (air, electric, hydraulic) to lube supply pump.

2.Turn off air supply to air manifold.

3.Using a wrench, slowly loosen fluid inlet fitting.

4.Using a wrench, slowly loosen each outlet port fit- ting.

5.Using a wrench, slowly loosen air inlet fitting.

Assembly Instructions

NOTE: The Air Over Oil Manifold is designed to mount to a standard Graco MSP divider valve. For instructions on how to use an MSP divider valve, refer to instruction manual 312497.

The Air Over Oil Manifold uses one-way air injectors to inject air into each of the individual divider valve lube outlet ports. Each air injector assembly is internally checked to prevent oil from entering the air supply sys- tem.

The Air Oil Valve does not utilize common porting between the lube outlets, therefore each outlet is both pneumatically and hydraulically independent.

An air pressure sensor is provided to monitor for any blockage or breaks in the air line.

The MSP divider valve can be used with a cycle indica- tor to monitor for proper oil lube cycles or blockage in any of the lubrication lines.

1.Remove alternate outlet port plugs from divider valves.

2.Loosen valve mounting socket head cap screws.

3.Place air over oil manifold over valves and hand tighten all air injectors to seat manifold on the valve stack. Then tighten air injectors with a wrench in a star pattern until all o-rings are seated in o-ring ports of valve and manifolds.

NOTE: The correct order is provided in chart on page 3.

4.Using valve mounting screw access ports, torque all valve mounting socket head cap screws to 8 - 9 foot/pounds (10.8 - 12.2 N•m).

5.The air supply may be induced into manifold using available ports, A1, A2, A3, or A4.

6.The air pressure sensor may be connected to any available port not connected to the air supply. This device warns of any blockage or breaks in the air line.

NOTE:

•Always use an air line filter of 40 micron or better to remove dirt and moisture from the compressed air supply.

•Install an air regulator to allow pressure adjustment.

Start Up Instructions

•System must be pre-filled with 100 psi (0.69 MPa, 6.9 bar) of air pressure. Once system is pre-filled and oil is being emitted from each dis- tribution line, system air may be reduced to final operating pressures.

•Minimum operating air pressure is 45 psi (0.31 MPa, 3.1 bar).

•Air pressure sensors are factory set to 35 psi (0.24 MPa, 2.4 bar) (Models 24B237, 24B239, 24B240, 24B241 only).
