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 knowledg eable personnel who un derstand 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.
Safety Guide
For more complete information on recommended application guidelines, see the
Safety Guide section of Pneumatic Division catalogs or you can download the
Pneumatic Division Safety Guide at: www.wilkersoncorp.com
Adsorber elements are not particle filters. All particles and
aerosols should be removed prior to adsorbing vaporous
contaminants. The initial pressure drop across an adsorber
element (1.5 PSIG maximum) should never increase. The
presence of any liquids, aerosols or particulate matter in an
adsorber 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
adsorber. 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 exceedes 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.

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. Adsorber elements are designed to adsorb vaporous
contaminates. The relative efficiency of an adsorber varies
depending on the vapor to be adsorbed and the environmental
temperature. At higher temperatures, adsorbers become less
efficient.
