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 person nel who understand how
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.

Introduction

Follow these instructions when installing, operating, or servicing
the product.

Application Limits

These products are intended for use in general purpose
compressed air systems only.

Filter / Regulator

Installation

1. The filter/regulator should be installed with reasonable
accessibility for service whenever possible – repair service kits
are available. Keep pipe or 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
the unit, possibly causing malfunction. Also, new pipe or hose
should be installed between the filter/regulator and equipment
being protected.

2. The upstream pipe work must be clear of accumulated dirt and
liquids.

3. Select a filter/regulator location as close as possible to the
equipment being protected.

4. Install filter/regulator so that air flows in the direction of arrow
on body.

5. Install filter/regulator vertically with the bowl drain mechanism
at the bottom. Free moisture will thus drain into the sump (“quiet
zone”) at the bottom of the bowl.

6. Gauge ports are located on both sides of the filter/regulator
body for your convenience. It is necessary to install a gauge or
socket pipe plugs into each port during installation.

Operation

1. Both free moisture and solids are removed automatically by the
filter.

2. Manual drain filters must be drained regularly before the
separated moisture and oil reaches the bottom of the baffle or
end cap.

3. The filter element should be removed and replaced when
pressure differential across the filter is 69 kPa (10 PSIG).

4. Before turning on the air supply, turn the knob counterclockwise
until compression is released from the pressure control spring.
Then turn knob clockwise and adjust regulator to desired
downstream pressure. This permits pressure to build up slowly
in the downstream line.

5. To decrease regulated pressure settings, always reset from
a pressure lower than the final setting required. 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).

6. When desired secondary pressure settings have been reached,
push the knob down to lock this pressure setting.

Service

Caution: Disconnect or shut off air supply and exhaust

the primary and secondary pressures before servicing
unit. Turning the adjusting knob counterclockwise
does not vent downstream pressure on non-relieving
regulators. Downstream pressure must be vented before
servicing regulator.

Note: Grease packets are supplied with kits for lubrication of

seals. Use only mineral based grease or oils. Do not use
synthetic oils such as esters. Do not use silicones.

Note: After servicing unit, turn on air supply and adjust regulator

to the desired downstream pressure. Check unit for leaks.
If leakage occurs, do not operate - conduct repairs and
retest.

Servicing Filter Element

Refer to picture for disassembling, servicing, and re-assembling
unit.

Servicing Regulator

1. 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 picture for
details.

3. Re-assemble unit. Refer to picture for details.

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.
