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 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.

CAUTION

Polycarbonate bowls, being transparent and tough, are ideal for use with
Filters and Lubricators. They are suitable for use in normal industrial
environments, but should not be located in areas where they could be
subjected to direct sunlight, an impact blow, nor temperatures outside of the
rated range. As with most plastics, some chemicals can cause damage.
Polycarbonate bowls should not be exposed to chlorinated hydrocarbons,
ketones, esters and certain alcohols. They should not be used in air systems
where compressors are lubricated with fire-resistant fluids such as phosphate
ester and di-ester types.

Metal bowls are recommended where ambient and/or media conditions are
not compatible with polycarbonate bowls. Metal bowls resist the action of
most such solvents, but should not be used where strong acids or bases are
present or in salt laden atmospheres. Consult the factory for specific
recommendations where these conditions exist.

TO CLEAN POLYCARBONATE BOWLS USE MILD SOAP AND WATER
ONLY! DO NOT use cleansing agents such as acetone, benzene, carbon

tetrachloride, gasoline, toluene, etc., which are damaging to this plastic.

Bowl guards are recommended for added protection of polycarbonate bowls
where chemical attack may occur.

WARNING

To avoid polycarbonate bowl rupture that can cause personal injury or
property damage, do not exceed bowl pressure or temperature ratings.
Polycarbonate bowls have a 150 psig (1030 kPa) pressure rating and a
maximum temperature rating of 52°C (125°F).

With Metal Bowl

Operating Pressure Maximum 1724 250 17.2
Operating Temperature Maximum 80°C (175°F)

Operating Temperature Minimum 0°C (32°F)

Note: The maximum recommended pressure drop for a particulate filter is
69 kPa (10 PSIG, 0.7 bar)

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.

WARNING

! WARNING

Product rupture can cause serious injury.

Do not connect regulator to bottled gas.

Do not exceed maximum primary pressure rating.

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 m ust
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 -

1. Unscrew the bottom threaded collar and remove bowl.

2. Unscrew the baffle and then remove element.

3. Clean all internal parts and bowl before reassembling. See polycarbonate
bowl cleaning section. IMPOR TANT: The Filter / Regulator will not oper ate
properly if the deflector is not installed properly. The deflector must be
installed between the filter holder and the filter body.

4. Install new element.

5. Attach baffle and finger tighten firmly.

6. Replace bowl seal. Lightly lubricate new seal to assist with retaining it in
position.

7. Install bowl into body and tighten collar; hand tight, plus 1/4 turn.

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. Remove the bonnet and bowl assemblies by unscrewing the two
threaded collars.

3. Remove diaphragm assembly from bonnet assembly.

4. Remove filter stem, filter element, valv e assembly, and valve return spring.

5. Clean and carefully inspect parts for wear or damage. If replacement is
necessary, use parts from service kits. Clean bowl. See polycarbonate
bowl cleaning section.

6. Lubricate o-ring and vee packing seals with grease found in service kits.

7. Install valve return spring, valve assembly, (seat) insert and its o-rings,
and filter stem. IMPORTANT: The Filter / Regulator will not operate
properly if the defector is not installed properly. The deflector must be
installed between the filter holder and filter body.

8. Install filter element and firmly tighten baffle onto the filter holder.

9. Install diaphragm assembly into bonnet assembly. Assemble bonnet
assembly to body and tighten threaded collar hand tight, plus 1/4 turn.

10.Install bowl into body and tighten collar; hand tight, plus 1/4 turn.
