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.

FAILURE OR IMPROPER SELECTION OR IMPROPER USE OF THE
PRODUCTS AND/OR SYSTEMS DESCRIBED HEREIN OR RELATED
ITEMS CAN CAUSE DEATH, PERSONAL INJURY AND PROPERTY
DAMAGE.

This document and other information from The Company, its subsidiaries
and authorized distributors provide product and/or system options for further
investigation by users having technical expertise. It is important that you
analyze all aspects of your application, including consequences of any
failure and review the information concerning the product or systems in the
current product catalog. Due to the variety of operating conditions and
applications for these products or systems, the user, through its own
analysis and testing, is solely responsible for making the final selection of
the products and systems and assuring that all performance, safety and
warning requirements of the application are met.

The products described herein, including without limitation, product features,
specifications, designs, availability and pricing, are subject to change by
The Company and its subsidiaries at any time without notice.

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 and equipment
being protected.

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

Torque:

0.5 - 0.6 Nm
(4.7 - 5.3 in-lbs)

Optional Electronic

Differential Pressure

Indicator
Using a straight blade
screwdriver, adjust clockwise
to increase differential /
counter-clockwise to
decrease differential.

3. Select a filter location as close as possible to the equipment
being protected and upstream of any pressure regulator.

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

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

Torque:

0.5 - 0.6 Nm
(4.7 - 5.3 in-lbs)

Operation and Service

1. Both free moisture and solids are removed automatically by
the filter. There are no moving parts.

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

3. The coalescing filter element should be removed and replaced
when pressure differential across the filter is 10 psid. The
differential pressure indicator, located on top of the filter
body, gives a visual indication of the pressure differential
across the filter element. Change the filter element when
half or more of the orange piston is above the retaining ring
when air is flowing. For units without a differential pressure
indicator, pressure differential gauges should be used to
determine when the maximum recommended pressure
differential has been reached.

4. Shut off air supply and depressurize the unit before servicing.

5.

After servicing, apply system pressure and check for air leaks.
If leakage occurs, Do Not Operate — conduct servicing again.

Lightly grease with provided lubricant. (Silicone free)
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.

Installation

1. The filter 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
