IMPORT ANT: Read and follow all Instructions and
Safety Precautions before installing, operating or
maintaining this equipment. Keep this manual for
future reference.
*Note
This range is not minimum or maximum outlet
pressure limit for the regulator. The regulator
can be adjusted to zero PSIG outlet pressure and
to pressures higher than 100 PSIG. However ,
this regulator should not be used to control pres-
sures outside this specified range.
Improper use can cause bodily injury or
equipment damage. Read the following: CONSTRUCTION MATERIALS
Bonnet and Valve Seat. Acetal
Diaphragm. Teflon/Buna-N/Teflon
Body. Zinc
Valve. Teflon
.This air regulator and gauge assembly is
intended only for use in general service air
systems. Do not use for liquids or gases
other than air .
.Do not use where pressure or tempera-
ture can exceed rated operating conditions
(see specifications).
.Regulated outlet pressure must never be
set higher than the maximum operating pres-
sure of the downstream air tool or equip-
ment. An outlet pressure gauge should al-
ways be used.
[::~~~!~~::]
The accuracy of the indication of pressure
gauges can change during shipment and nor-
mal use. If gauge accuracy is necessary for
preventing risks of injury or property dam-
age, the gauge should be checked before
use and on a routine periodic basis. (See
ANSI 840-1974 for gauge standards.}
SPECIFICA TIONS
DESCRIPTION
This unit is used in a compressed air system to main-
tain a nearly constant outlet pressure despite change
in inlet air pressure and changes in downstream flow
requirements. It is also used for finer control of air
at the spray device. The air setting can be locked in
place by pushing the adjusting knob downward.

INST ALLA TION CLEANING
~
Do not submerge regulator in spray gun sol-
vents or use solvents to clean regulator
parts. Damage may occur to gauge or regu-
lator components.
1. Install regulator as close as possible to the de-
vice being serviced. Regulator can be installed
at any angle.
2. In systems with a cyclic demand, install regula-
tor upstream of cycling control valves.
3. Air line piping should be same size as regulator
ports.
4. Air flow must be in same direction as arrow on
bottom of regulator body.
OPERA TION
1. Clean parts using warm water and soap.
2. Inspect all parts and replace any damaged ones.
Reassembly:
1. At reassembly, apply a small amount of lubricant
SSL-10 gun lube to adjusting screw threads in-
side bonnet.
2. Torque valve seat (5) to 4-6 in./lbs. (do not over-
tighten). Torque bonnet to 50-60 in./lbs.

1. Before turning on system air pressure, turn ad-
justing knob full counterclockwise. This will close
regulator to produce zero air pressure. The knob
is locked in position when pushed downward to-
wards the regulator body.
2. Turn on system air pressure.
3. Turn regulator adjusting knob clockwise until
desired outlet pressure is reached.
4. To avoid minor readjustment after making a
change in pressure setting, always approach the
desired pressure from a lower pressure. When
reducing from a higher to a lower setting, first
reduce to some pressure less than that desired,
then bring up to the desired point. Lock !be pres-
sure setting by pushing the knob downward.

PREVENT A TIVE MAINTENANCE
r:=J
Risk of injury from pressurized components.
Turn off inlet air pressure and bleed off re-
maining pressure before disassembly.
1. Turn regulator knob counterclockwise until it
stops.
2. Unscrew the bonnet from the regulator body, re-
move adjusting screw and nut, then the regulat-
ing spring (4), slip ring (5) and diaphragm (6).
Using a screwdriver, unscrew the valve seat (7)
and gasket. Then remove valve (8) and valve
spring (9).
