WARNING
To avoid unpredictable system behavior that can cause personal injury
and property damage:
• Disconnect electrical supply (when necessary) before installation,
servicing, or conversion.
• Disconnect air supply and depressurize all air lines connected to this
product before installation, servicing, or conversion.
• Operate within the manufacturer’s specified pressure, temperature,
and other conditions listed in these instructions.
• Medium must be moisture-free if ambient temperature is below
freezing.
• Service according to procedures listed in these instructions.
• Installation, service, and conversion of these products must be
performed by knowledgeable personnel who understa nd h ow
pneumatic products are to be applied.
• After installation, servicing, or conversion, air and electrical supplies
(when necessary) should be connected and the product tested for
proper function and leakage. If audible leakage is present, or the
product does not operate properly, do not put into use.
• Warnings and specifications on the product should not be covered by
paint, etc. If masking is not possible, contact your local representative
for replacement labels.
WARNING
Product rupture can cause serious injury.
Do not connect regulator to bottled gas.
Do not exceed maximum primary pressure rating.

Installation
1. The regulator should be installed with reasonable accessibility
for service whenever possible - repair service kits are available.
Keep pipe and tubing lengths to a minimum with inside clean
and free of dirt and chips. Pipe joint compound should be used

sparingly and applied only to the male pipe - never into the
female port. Do not use PTFE tape to seal pipe joints - pieces
have a tendency to break off and lodge inside unit, possibly
causing malfunction.
2. Install regulator so that air flow is in the direction of arrow.
Installation must be upstream (high pressure) side and as
close to the devices it is to service (valve, cylinder, tool, etc.).
Mounting may be in any position.
3. Gauge ports are located on both sides of the regulator body.
It is necessary to install a gauge or pipe plugs into each port
during installation.
4. For protection against rust, pipe scale, and other foreign matter,
install a filter on the upstream (high pressure) side as close to
the regulator as possible.
Operation
1. Before turning on the air supply, turn the adjusting knob or
“T” handle counterclockwise until compression is released
from the control spring. Then turn on air supply and adjust
regulator to desired secondary pressure by turning adjusting
knob/handle clockwise. This permits pressure to build up slowly,
preventing any unexpected operation of the valve, cylinders,
tools, etc., attached to the line. Adjustment to desired secondary
pressure can be made only with primary pressure applied to
the regulator.
2. To decrease regulator pressure setting, always reset from a
pressure lower than the final setting desired. For example,
lowering the secondary pressure from 550 to 410 kPa (80 to 60
psig) is best accomplished by dropping the secondary pressure
to 350 kPa (50 psig), then adjusting upward to 410 kPa (60
psig).
Push the adjusting knob down to lock the pressure setting. On
the “T” handle units, tighten the hex nut against the bonnet to
lock setting.
Service
CAUTION:
SHUT OFF AIR SUPPLY and exhaust the primary and
secondary pressure before disassembling regulator unit.
(Tur ni ng the knob/handle counterclockwise reduces
regulator’s setting, but does not vent downstream pressure
on non-relieving regulators.)

CAUTION:
Lubricate parts with a mineral based oil/grease or silicone
grease. DO NOT use synthetic oils/greases such as esters.
A. Use the following procedure to service bonnet assembly and
components.
1.
(Adjustable Regulator only) Disengage the adjusting knob by
pulling upward. Turn adjusting knob counterclockwise until the
compression is released from the pressure control spring.
2. Disassemble and service as required. Refer to pictures for
details.
3. Reassemble Unit. Refer to pictures for details.
B. Servicing the Poppet Assembly
1.
(Adjustable Regulator only) Disengage the adjusting knob by
pulling upward. Turn adjusting knob counterclockwise until the
compression is released from the pressure control spring.
2. Remove bottom cap:
a) Remove screw
b) Turn cap and pull down counter clockwise.
3. Disassemble parts and services as required. Refer to pictures
for details.
4. Reassemble unit. Refer to pictures for details.
Turn on air pressure and check regulator for leakage. If leakage
occurs, DO NOT OPERATE — conduct repairs again.
Lightly grease with provided lubricant.
Inspect for nicks, scratches, and surface
imperfections.
If present, reduced service life is probable and
future replacement should be planned.
Clean with lint-free cloth.
Adjust to desired secondary pressure as described in the operation
section.
If you have questions concerning how to service this unit,
contact your local authorized dealer or your customer service
representative.
