INSTALLATION
Before installing any air line components, blow out the
pipe
line to remove scale and other debris. Use pipe com -
pound
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 8.
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 re-
lieving system air pressure, close the bleed–type
master
air valve to fully relieve air pressure.
WARNING
To provide the user with a variety of assembly options, a
bleed–type master air valve is not included with all regu -
lator 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 4.
ADJUSTMENT
Relieving Pressure
1. Close the bleed–type master air valve to bleed air be -
tween
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. T ighten 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.

REPAIR
WARNING
Relieve
air and fluid pressure before servicing the
regulator.
To reduce the risk of serious bodily injury, fluid in-
jection, splashing in the eyes or skin, injury from
moving
parts, AL WA YS open the bleed–type mas -
ter air valve (required) to relieve system air pres-
sure and trigger the gun or dispense valve and
open
any fluid drain valves to relieve fluid pressure.
If the regulator fails to operate, operates roughly, vi-
brates, etc., follow the WARNING above. Remove the
regulator
and service it as follows.
Disassemble the regulator . See the drawings on page 5.
Wash the parts with household soap and water or dena -
tured 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.
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 dia -
phragm. Torque the spring housing to 45 in–lb
(51
N.m).
