INSTALLATION INSTRUCTIONS
(continued)
7. Shut off the system inlet valve located on the inlet of the prefilter head.
8. Check to be sure the O-ring on the prefilter housing is sufficiently lubricated.
Use a good grade of silicone lubricant, if needed. Position the prefilter
cartridge on guide seat in the bottom of the bowl. Then thread the bowl into
the head by hand. Use a sump wrench to snug the bowl onto the head.
9. Install the carbon filter cartridge(s) into the filter head(s) following directions
on the cartridge label or as shown in the Cartridge Change illustrations.
10. Turn on inlet water to the filter system and check for leaks.
11. Open the flushing valve and flush the cartridge(s) by running water through at
full force for ten (10) minutes. This will set the filtering media and purge any
air and fines, insuring maximum filter life. See illustrations.
12. After flushing, close the flushing valve, turn on power to equipment. The
system is ready for operation.
FLUSHING
For maximum life, all carbon filter cartridges must be flushed for fen (10) minutes
at full flow before use.
ALL NEW CARTRIDGES MUST BE FLUSHED AFTER EACH CARTRIDGE CHANGE
BEFORE BEING PUT INTO SERVICE!
If the cartridges are new, have been properly flushed and both needle and follower
register inadequate pressure, or the LPA is sounding, you may be experiencing
inadequate water pressure or some restriction may exist in the inlet water line. In
either case, the incoming water pressure must be improved to receive optimum
filter life.
COMPLETE CARTRIDGE CHANGE INSTRUCTIONS CAN BE FOUND ON THE FILTER
CARTRIDGE LABEL.
CARTRIDGE CHANGE DETERMINATION
Replace the prefilter cartridge whenever it becomes excessively dirty (observed
visually or by flow restriction). Follow the change instructions provided with the
cartridge. Replace filter cartridges when capacity is reached, or when flow becomes
inadequate, but at least annually. All filter cartridges on multiple cartridge systems
should be changed at the same time. The system pressure gauge or accessory (sold
separately) Everguard Low Pressure Alarm (LPA) provide a quick, simple means of
determining when the filter cartridge(s) should be checked. Installed on the system
outlet manifold, the gauge or LPA can be used to monitor both dynamic (flowing)
and static (line) pressure. The cartridge(s) should be changed when the pressure
gauge needle is in the red area while equipment is in operation, and yet the needle
shows adequate line pressure between cycles. Observe the needle during the next
equipment on cycle. If the needle registers adequate pressure, it can be assumed
that the temporary low-pressure condition was caused by a brief power failure or
other incoming pressure disruption. If the low pressure condition is not due to an
external condition, check/change the prefilter first. If the low pressure condition is
still not corrected, change the filter cartridges.
