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

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.

Operation and Service
1. The particulate and coalescing filter element should be
removed and replaced when pressure differential across
the filter is 10 PSID.
2. Absorber elements are designed to absorb vaporous
contaminates. The relative efficiency of an absorber varies
depending on the vapor to be absorbed and the
environmental temperature. At higher temperatures,
absorbers become less efficient.
Absorber elements are not particle filters. All particles and
aerosols should be removed prior to absorbing vaporous
contaminants. The initial pressure drop across an absorber
element (1.5 PSIG maximum) should never increase. The
presence of any liquids, aerosols or particulate matter in
an absorber indicates that the effective life of the element
has been exceeded and the element should be replaced
and the system cleaned.
The most effective method of testing whether an element
needs to be replaced is to smell the air coming from the
absorber. Offensive odors will be present well before oil
levels become detectable.
3. If the electronic differential pressure indicator, located on
top of the filter body is wired as normally open, it sends an
electrical signal when the differential is greater than the
specified range. If the electronic differential pressure
indicator is wired as normally closed, there will be a signal
until the differential exceeds the specified range. Change
the filter element when this happens. 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.
