8. MAINTENANCE
8.1 FILTER HANDLING AND REPLACEMENT
Filter Handling: Any rough handling of the paper media may result in
a ruined filter. This includes bumping, dropping, denting, abrading,
and/or sliding. Only handle filters by the top and/or bottom steel
pan. Handling paper media can result in tearing the filter media,
resulting in dust leaking through the media.
Filter Removal:
1. Lift cam lever and lock lever in extended position.
2. Using lever in extended position lower filter lift rail
assembly. Repeat this on both sides of filter.
3.
3. Once both lift rails are lowered, filter can then be removed from
unit by pulling filter out by top pan. Handling filter by paper filter
media can permanently damage filter.
4. Once all filters are removed from the row, new ones can be
reinserted using the opposite procedure.
8.2 SAFETY VALVE MAINTENANCE
If a valve is discovered to be leaking it can be cleared by manually
operating the valve to a pressure that will cause it to operate. Please
note that valves with metalto-metal seats are not absolutely “bubble
tight” and they will allow a pressure loss over a period of time. If a
valve has a leak it should be replaced, as leaks are self-propagating.
Safety relief valves must be inspected and tested for operation
periodically. It is the users responsibility to determine the frequency
of inspection as he is the only party familiar with the operating
conditions and the relative hazards of an inoperative valve. It is
recommended that at the very least each valve should be inspected
semi-annually. Local ordinances may require more frequent
inspection. Testing should be done by operating the valve either
through the use of the operating device on the valve or if it doesn’t
have an operating device it should be connected to a source of
pressure that will cause it to operate.
Valves that are capacity certified by the ASME are factory sealed.
Tampering, altering, or adjustment of these valves voids any warranty
and liability of the manufacturer. Repairs or resetting will be made
only by the factory. Please contact the factory prior to returning any
valve for service and securely package valves for shipping.
