Installation

Before installing any air line components, blow out the
pipe line to remove scale and other debris. Use pipe
compound or tape sparingly and only on male threads.
Install the regulator in the pipe line so the flow is in the
direction of the arrow stamped on the body. Locate the
regulator as close as possible to the equipment it
serves.

Mounting brackets and nuts are available. See page

10.

WARNING

To reduce the risk of serious bodily injury, including
fluid injection, splashing fluid in the eyes or on the
skin, or injury from the pump starting unexpectedly,

be sure your system includes a bleed–type
master air valve.

Install the air valve between the air regulator outlet
and the device the regulator is serving. When
relieving system air pressure, close the bleed–type
master air valve to fully relieve air pressure.

To provide the user with a variety of assembly options,
a bleed–type master air valve is not included with all
regulator assemblies. See ACCESSORIES to order
this valve. Another bleed–type master air valve may
also be installed upstream from the air controls to
isolate them for servicing.

Be sure the air to the regulator is clean. Erratic regula­tor operation or loss of regulation is usually caused by
dirt in the disc area. To clean the regulator, see the
REPAIR section on page 6.

Adjustment

Relieving Pressure

1. Close the bleed–type master air valve to bleed air
between the valve to the device it is serving.

2. Trigger the gun or dispense valve and open any
fluid drain valves to relieve fluid pressure.

Adjusting Pressure with a
T-Handle Regulator

3. Loosen the locknut.

4. To increase the regulated air pressure, turn the
T-handle clockwise.

5. To decrease the regulated air pressure, turn the
T-handle counterclockwise.

6. Tighten the locknut to lock in the adjustment.

Adjusting Pressure with a Knob–type
Regulator

1. If the knob does not have a screw, pull the knob

up to adjust. When the adjustment is complete,
push the knob down to lock it in place.

2. If the knob has a cross–head screw, loosen the

screw 1/4 turn and the adjust the knob. Tighten the
screw to lock in the adjustment.

3. To increase the regulated air pressure, turn the

knob clockwise.

4. To decrease the regulated air pressure, turn the

knob counterclockwise.

WARNING

Relieve air and fluid pressure before servicing the
regulator.

o reduce the risk of serious bodily injury, fluid
injection, splashing in the eyes or skin, injury from
moving parts, ALWAYS open the bleed–type mas­ter air valve (required) to relieve system air pres­sure and trigger the gun or dispense valve and
open any fluid drain valves to relieve fluid pressure.

Wash the parts with household soap and water or
denatured alcohol. Wipe the parts dry with a clean,
soft, dry rag. Use compressed air to blow dirt and
contaminants out of the regulator body.

CAUTION

Do not use trichloroethylene, acetone or similar
solvents to clean the regulator. These solvents could
damage the regulator parts.

Inspect all parts for wear or damage. Replace dam­aged parts.

If the regulator fails to operate, operates roughly,
vibrates, etc., follow the WARNING above. Remove
the regulator and service it as follows.

Disassemble the regulator. See the drawings on page

7.

Lubricate the bearing area, adjusting screw threads,
and spring ends with No. 2 lithium-base grease. Reas­semble the regulator.

When installing the diaphragm, be sure the disc is
firmly in place. Install the disc stem in the center hole
of the diaphragm. Torque the spring housing to
45 in–lb (51 N.m).

Graco equipment with structures, accessories, equipment or materials not supplied by Graco, or the improper design, manufacture,
installation, operation or maintenance of structures, accessories, equipment or materials not supplied by Graco.

This warranty is conditioned upon the prepaid return of the equipment claimed to be defective to an authorized Graco distributor for
verification of the claimed defect. If the claimed defect is verified, Graco will repair or replace free of charge any defective parts. The
equipment will be returned to the original purchaser transportation prepaid. If inspection of the equipment does not disclose any defect
in material or workmanship, repairs will be made at a reasonable charge, which charges may include the costs of parts, labor, and
