Receiving and Inspection
Upon receipt of the filter(s), immediately check for damage that may have occurred during shipping. If there is
any damage, do not install or attempt to repair the filter. File a claim with the shipping company and contact
either your local distributor or contact manufacturer’s customer service department for further instructions.
Since the filter is shipped F.O.B. factory, the carrier is not covered by filter warranty.
WARNING!
FAILURE OR IMPROPER SELECTION OR IMPROPER USE OF THE PRODUCTS AND/OR
SYSTEMS DESCRIBED HEREIN OR RELATED ITEMS CAN CAUSE SEVERE INJURY OR PROPERTY DAMAGE.
Installation
All filters, coalescer, adsorbers should be installed at the highest pressure point available, and as near as
possible to the equipment to be protected with a drip leg immediately upstream. The coalescer should be in a
visible and easily accessible location for periodic draining and maintenance.
All filters should be selected based on compressed air flow rate and pressure, not on the basis of pipe size. If
new piping is installed, pipe size must also be selected on the basis of flow rate and pressure. Be sure all piping
is supported.
Filters should be piped in accordance with the instruction tags, flow arrows, and “IN” and “OUT” labels
supplied with the filter. See recommended system installation diagram in this manual.
Before filter installation, the customer may wish to install a pressure relief device in accordance with paragraphs
UG-125 through UG-136 of the ASME Boiler and Pressure Code section VIII-division I. You may also wish to
check with local requirements.
Filter Bypass
A three-valve bypass around the filter is recommended so that the elements can be charged without shutting
down the branch or complete air system. Piping should not be allowed to place any stress on the filter
connections.
For systems that can not tolerate unfiltered air during element replacement, a second filter should be installed in
the bypass. See installation diagrams.
Element Replacement
As the filter is used, the replaceable element will become plugged with particles from the air stream. The
gradual buildup of these particles will cause an ever increasing pressure drop through the element. This
pressure drop will be indicated by the differential pressure gage that is provided with the filter. The filter should
be changed when the indicator suggests the element is plugged. The increasing pressure drop will cause a
reduction in the air system efficiency.
WARNING!
COMPLETELY VENT INTERNAL AIR PRESSURE TO ATMOSPHERE BEFORE
DISASSEMBLING FILTER.
