OPERATING INSTRUCTIONS

Refer to pages 4 and 5 for parts reference.

To INCREASE outlet pressure, turn the (6) adjusting screw CLOCKWISE (see figure 3).

To DECREASE outlet pressure, turn the (6) adjusting screw COUNTERCLOCKWISE (see figure 3).

NOTE: Part Y106-109 Allen wrench is included to make neces- sary pressure adjustments.

FLUSH-OUT FEATURE FOR DOWNSTREAM MODELS ONLY. See figure 4.

Flush the regulator periodically. The interval may vary de- pending on the amount and type of material used.

By using a wrench and “flush-out” plug (provided), the operator is able to move the entire spindle downward and force the ball off the seat which should purge the regulator of particle build-up.

NOTE: The flush-out procedure temporarily overrides the adjusted pressure. It will not, however, affect the regulator setting when flushing operation is completed.

FLUSH-OUT PROCEDURE

1.Remove spray gun or dispensing device, this will allow any particles to clear from the system.

2.Insert (21) flush-out plug and turn clockwise until it touches the (4) washer (see view on page 5).

3.Turn up to two turns maximum. This will allow the ball to unseat and pass material at free flow (unregulated). DO NOT attempt to turn further to avoid damage.

4.Turn the plug back to its original position.

SEAT PLUG FEATURE

The (47) plug, located at the base of the regulator, can be removed for access to the ball and seat assembly for clean- ing and inspection for wear. With this feature, the regulator does not have to be unthreaded from the pumping system. Be certain to relieve system pressure (See “WARNING: DISAS- SEMBLY HAZARD”).

MAINTENANCE

Disassembly should be done on a clean work bench and use clean cloths.

If replacement parts are necessary, refer to the parts list and drawings on pages 4 and 5.

Upon reassembly, lubricate parts and use Loctite where indicated. Follow the torque specifications as shown. Service kits are available, which include parts typically needed for an overhaul.

Keep good records of service activity and include the regulator in a preventive maintenance program.

Certain “Smart Parts” are indicated with a “ ” in the parts list, these parts should be available for fast repair and re- duction of down time.

TROUBLE SHOOTING

No fluid pressure.

Check for damaged or worn diaphragms.

Look for possible obstruction by hardened material or foreign matter, periodically use the regulator “Flush-out” feature (Downstream models only). Use a fluid filter up- stream from the regulator.

Pressure creeps above the setting when system is dead ended and in a static (no flow) mode.

Check for dirty seat and clean as appropriate.

Check for worn or damaged seat and replace if necessary.

Outlet pressure drops below setting.

Check pump for proper operation and check for possible leakage problems.

Look for a clogged supply line problem, flush the supply line.

Fluid leakage from spring housing.

Check the bonnet hold-down screws and the plate hold down screws and re-torque as needed.

Check for damaged diaphragm, replace as needed.

Regulator will not function, even when dispens- ing device is opened.

Check for possible obstruction in the fluid line.

Inlet pressure is too high, causing a “Lock-Out” situation. Read “WARNING: MISAPPLICATION HAZARD” found on page 2.
