READ THIS MANUAL CAREFULLY BEFORE INSTALLING,
OPERATING OR SERVICING THIS EQUIPMENT.
It is the responsibility of the employer to place this information in the hands of the operator. Keep for future reference.
SERVICE KITS
Use only genuine ARO® replacement parts to assure com-
patible pressure rating and longest service life.
Order 637219-XXX-B rebuild kit (see chart below) for gen-
eral repair of the regulator. This includes a diaphragm kit
and a valve kit.
Fluid diaphragm kit 61962-1 can be ordered separately
(see page 4).
Valve kit can be ordered separately (see page 4).

OPERATING INSTRUCTIONS
TROUBLE SHOOTING
Refer to pages 4 and 5 for parts reference.
No fluid pressure.
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).
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.
ꢀ
NOTE: Part Y106-109 Allen wrench is included to make neces-
sary pressure adjustments.
Pressure creeps above the setting when system is
dead ended and in a static (no flow) mode.
FLUSH-OUT FEATURE FOR DOWNSTREAM MODELS ONLY.
See figure 4.
Check for dirty seat and clean as appropriate.
ꢀ
ꢀ
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.
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.
ꢀ
NOTE: The flush-out procedure temporarily overrides the
adjusted pressure. It will not, however, affect the regulator
setting when flushing operation is completed.
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.
ꢀ
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.
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.
ꢀ
ꢀ
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
Adjusting Screw
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.

TOOLS REQUIRED: Small bench vise, 3/8” Allen wrench
(Y106-109 is included), 5/32” Allen wrench, a 9/16” Allen
wrench for -CXX-B models, torque wrench and Loctite 242.
NOTE: It is not always necessary to remove the regulator from
the fluid line to service or inspect only the valve section.
BEFORE DOING ANY IN-LINE SERVICE, ALL FLUID PRES-
SURE MUST BE RELIEVED. HEED ALL WARNINGS FOUND
ON PAGE 2.
NOTE: The (6) adjusting screw, (5) thrust bearing and (4)

is included and can be used for several functions including:
Regulator adjustment (spring type models), removal and as-
sembly of the long bonnet bolts and the short plate bolts.
VALVE SEAT NOTE: Before deciding to order a general repair
kit to service the whole regulator, check the easiest things
first. Remove and inspect the valve seat for dirt, foreign mat-
ter, damage or wear (steps 1 - 3).
REMOTE MODELS (Refer to figure 8)
1. Remove four (34) screws from (30) air cap and separate
