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.
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 re-
lieving system air pressure, close the bleed–type
master air valve to fully relieve air pressure.
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. Tighten the locknut to lock in the adjustment.

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.
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.
