Installation
4308167N
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 that 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 12.
To provide a variety of assembly options, a bleed-type
master air valve is not included with all regulator
assemblies. See Accessories, page 11 to order this
valve. Another bleed-type master air valve may also be
installed upstream from the air controls to isolate them for
servicing.
The air to the regulator should be clean. Erratic regulator
operation or loss of regulation is usually caused by dirt in
the disc area. To clean the regulator, see Repair, page 6.
WARNING
To reduce the risk of serious bodily injury, including
fluid injection, splashing fluid into the eyes or onto the
skin, or injury from the pump starting unexpectedly,
be sure the system includes a bleed-type master air
valve.
Install the air valve between the air regulator outlet
and the device that the regulator is serving. When
relieving system air pressure, close the bleed-type
master air valve to fully relieve air pressure.
Operation
308167N 5
Operation
Adjust Pressure
1. If the knob does not have a screw, pull the knob up
to adjust. When adjustment is complete, push the
knob down to lock in place.
2. If the knob has a cross-head screw, loosen the
screw 1/4 turn and then 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.

Repair
If the regulator fails to operate, operates roughly,
vibrates, etc., follow the above Warning. Remove the
regulator and service as follows:
Disassemble the regulator. See the Repair Kit
Drawings on page 7.
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 any dirt and
contaminants out of the regulator body.
Inspect parts for damage or wear. Replace any
damaged parts.
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 that the disc is
firmly in place. Install the disc stem into the center hole of
the diaphragm. Torque the spring housing to 45 in-lb
(51N•m).
WARNING
Relieve air and fluid pressure before servicing the
regulator.
To help prevent serious injury from pressurized fluid,
such as skin injection, splashing fluid, and moving
parts, relieve pressure on both the inlet and outlet
sides of the regulator before servicing.
Inlet: Turn off the air supply and depressurize the air
line connected to the inlet.
Outlet: Open the bleed-type master air valve
(required on the outlet side) to relieve system air
pressure, and trigger the gun or dispense valve and
open any fluid drain valves to relieve fluid pressure.
NOTICE
Do not use trichloroethylene, acetone or similar
solvents to clean the regulator. These solvents could
damage the regulator parts.
