Refer to pages 4 and 5 for parts reference.

To INCREASE outlet pressure, turn the (6) adjusting screw 
CLOCKWISE (see fi gure 3).
To DECREASE outlet pressure, turn the (6) adjusting 
screw COUNTERCLOCKWISE (see fi gure 3).

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

FLUSH-OUT FEATURE FOR DOWNSTREAM MODELS ONLY. 
See fi gure 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 fl ushing operation is completed.

Remove spray gun or dispensing device, this will allow 
any particles to clear from the system.
Insert (21) flush-out plug and turn clockwise until it 
touches the (4) washer (see view on page 5).
Turn up to two turns maximum. This will allow the ball to 
unseat and pass material at free fl ow (unregulated). DO 
NOT attempt to turn further to avoid damage.
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”).

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 specifi cations 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.

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 fl uid fi lter up-
stream from the regulator.

Check for dirty seat and clean as appropriate.
Check for worn or damaged seat and replace if necessary.

Check pump for proper operation and check for possible 
leakage problems.
Look for a clogged supply line problem, fl ush the supply 
line.

Check the bonnet hold-down screws and the plate hold 
down screws and re-torque as needed.
Check for damaged diaphragm, replace as needed.

Check for possible obstruction in the fl uid line.
Inlet pressure is too high, causing a “Lock-Out” situation.
