Filter Replacement Schedule & Procedure
Your carbon filter protects your system from damaging chlorine and
water disinfection agents. It is recommended that you change your
carbon filter cartridge every 6 months. Failure to do so will void your
warranty. Order RHG #20066-C.
Your DI filter has a limited lifespan based on the amount of dissolved
solids it is removing from the water. DI filter cartridges need to be
replaced as needed for your cleaning application.
Order RHG #20066-D.
To change your filter cartridge, first disconnect any hoses from the
elbow in the insert at the top of the filter housing. Remove the stainless
steel U-Pin. Depress the insert into the housing
slightly
. Filter inserts can
be pried out using the stainless U-Pin. (See diagram included in this
literature) Remove the spent filter cartridge and replace.
To install the new filter, put the new filter into the housing the same
way the previous one was installed. There is an o-ring on the filter.
This o-ring should go at the top end of the housing. Insert the filter from
the opposite end first. Be sure to run water through the system without
any booster motor/pump assembly powered on to purge all air out of
the system before or you risk damaging the filters.
Reassemble filter housing and reconnect hoses. You may need to
relubricate your filter housing insert to ensure a tight seal. Use a silicone
valve stem lubricant. RHG uses Dow Molykote 111. Flush new carbon
filter cartridge if needed.
RO membranes have a much longer service life and in the experience of
RHG may last the life of the system. However ROs are only warrantied
for factory defect and may eventually diminish in performance or fail. If
you experience a reduction in RO performance in your H2Pro system,
contact RHG directly to troubleshoot.
RO MEMBRANES SHOULD NOT BE ALLOWED TO DRY OR COLLECT STAGNANT
WATER IN THE BOTTOM OF THE MEMBRANE. THIS WILL DIMINISH
PERFORMANCE, POTENTIALLY TO THE POINT OF FAILURE. TO PREVENT THIS,
ROs SHOULD BE RUN ON A REGULAR BASIS, AT LEAST EVERY TWO WEEKS, AFTER
FIRST USE, EVEN DURING “OFF-SEASON”.
