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.

INSTALLATION

Install the Filter/Regulator as close as possible to the application. The
inlet port is marked with an arrow cast into the body to indicate the
direction of flow. Gauge ports (1/4") are provided in either side of the
body for installation of a gauge or use as an additional outlet port.
Plug unused port(s). System piping should be same size as regulator
porting. In systems with a cyclic demand, the regulator should be
located upstream of cycling device.

! WARNING

Product rupture can cause serious injury.

Do not connect regulator to bottled gas.

Do not exceed maximum primary pressure rating.

OPERATION
Maximum pressure rating is 150 psig (10 bar) for transparent

plastic bowls, and 200 psig (14 bar) for metal bowls.
Temperature range is 32°F to 125°F (0°C to 52°C) for transparent
plastic bowls, and 32°F to 150°F (0°C to 65.5°C) for metal bowls.

Before turning on the supply air pressure, turn the adjusting knob
counterclockwise until there is no load on the regulating spring. Turn
on the supply air pressure and then turn the adjusting knob clockwise
until the desired secondary pressure is reached. To avoid minor
readjustment after making a change in pressure setting, always
approach the desired pressure form a lower pressure. When reducing
from a higher to a lower setting, first reduce to some pressure less
than that desired and then increase to the desired pressure.

SEE REVERSE SIDE FOR LIST OF MATERIALS

UNSUITABLE FOR USE WITH POLYCARBONATE BOWLS

MAINTENANCE

1. The regulator can be disassembled for servicing without removal
from line.

2. DEPRESSURIZE UNIT BEFORE REMOVING GUARD AND/OR
BOWL.

3. TO DISASSEMBLE: shut off air to the filter/regulator and vent air
line on both sides of unit. Turn adjusting screw counterclockwise
to relieve spring compression. Remove knob, cover cap, screw
cover, and spring. Diaphragm assembly can now be removed.

4. To remove valve from bottom of unit, remove bowl. Remove baffle
and filter element exposing hex nut on adapter assembly.
Remove adapter assembly, valve and spring.

5. If unit is equipped with plastic bowl, inspect daily to detect
crazing, cracking, damage, or other deterioration. Immediately
replace any crazed, cracked, damaged, or deteriorated bowl with
a metal bowl or a new plastic bowl and metal bowl guard.

6. Replace or clean the filter element periodically by removing from
filter, tapping on surface, and blowing off with air blow gun.

7. If unit is equipped with a manual petcock, drain bowl at least once
per work shift.

8. If unit is equipped with a float, clean the bowl each time the
element is cleaned or changed by turning the bowl upside down
and tapping onto tabletop. Blow clean with blow gun.

9. If unit will not regulate to required pressure, or if pressure
becomes excessive, follow instructions (see step 4) for removal of
valve. Remove valve and spring (Clean and check valve stem
and valve seat for wear or damage and replace if required.)

10. Before placing unit in service, make sure that bowl and bowl
guard are reinstalled and securely locked in place.

WARNING: IF YOUR UNIT HAS A PLASTIC BOWL

1.

DO NOT use plastic bowl units without a metal bowl guard installed.
Plastic bowl units are sold only with metal bowl guards to minimize
the danger of flying fragments in the event of bowl failure.

2. DO NOT install the unit where it will be subjected to temperatures
higher than 125°F (52°C).

3. DO NOT install the unit where it will be subjected to pressure
higher than 150 psig (10 bar).

4. CAUTION: Certain compressor oils, household cleaners,
chemicals, solvents, paints and fumes will attack plastic bowls
and can cause plastic-bowl failure. See manufacturer's list below.
Do not use near these materials.

!

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.
