Bowl guards are recommended for added protection of polycarbonate bowls
where chemical attack may occasionally 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 pressure rating and a maximum
temperature rating of 125°F.
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

INSTALLATION
1. Refer to WARNINGS and CAUTIONS prior to installation.
2. Install as close to the point of use as possible.
3. Unit must be installed with the flow in the direction of the flow arrow on
the body cover and with bowl down.
4. Avoid using reducing bushings, couplings, etc., whenever possible
to install this product. These devices restrict air flow and can affect
performance.
5. Do not install this product in any application where the pressure
drop across the unit will exceed 7 psig (0.5 bar). This will cause the
Differential Pressure Indicator to shift to RED indicating element
replacement is required.
6. Maximum pressure rating is 150 psig (10.3 bar) for plastic bowl/bowl
guard assembly, and 250 psig (17.2 bar) for metal bowl with sight
gauge. Temperature range is 32°F to 125°F (0°C to 52°C) for plastic
bowl/bowl guard assembly, and 32°F to 150°F (0°C to 65.5°C) for
metal bowl with sight gauge.
7. To install a drain line, use the following procedure:
a. On units with the MANUAL DRAIN, attach flexible tubing having an
I.D. of 3/16” (4.8 mm) to drain stem.
b. On units with AUTOMATIC FLOAT DRAIN, install using a 3/8
or 10mm ID instant tube fitting or 3/8" ID flexibile tubing.
NOTE: CONTAMINATES REMOVED FROM THE COMPRESSED AIR
SYSTEM MUST BE DISPOSED OF IN ACCORDANCE WITH LOCAL,
STATE AND FEDERAL STANDARDS.
MAINTENANCE
THIS UNIT MAY BE SERVICED WITHOUT REMOVING THE
UNIT FROM THE COMPRESSED AIR LINE.
1. Filter element replacement:
a. Differential Pressure Indicator is RED indicating that the filter element
requires servicing.
b. Depressurize unit.
c. Remove bowl/bowl guard assembly by pushing up on bowl assembly
and turning counter clockwise. Clean inside of bowl using a clean
cloth. Inspect plastic bowl for damage and replace if necessary.
d. Remove filter element by turning element clockwise.
e. Install a new filter element / O-ring seal and reassemble unit in reverse
order.

CAUTION
Polycarbonate bowls and sight domes, 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 and sight domes should not be exposed to chlorinated hydro-carbons,
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.
