How to change the Filter Cartridge
Please Read Through Each Step Before Beginning
The filter change is recommended once per year
We recommend that this
system be inspected by a qualified service technician on a yearly basis.
STEP 1 Turn off the feed water valve to the RO system. Turn off Valve on the
storage tank. Open RO faucet an allow all pressure to bleed off. (Allow
a few minutes for the system to drain completely).
STEP 2 Unscrew the filter housing and remove the used filter cartridge.
(A special wrench is available from your Dealer).
STEP 3 Carefully remove the o-ring seal from its groove and rinse out the
housing.
Be aware that the o-ring may lift out of the groove or stick to the cap.
STEP 4 Wipe the o-ring clean with a soft rag or towel and visually inspect for
any nicks, cuts, or abrasions. If damaged, replace the o-ring.
STEP 5 Lubricate the o-ring lightly with a suitable o-ring lubricant. Replace the
o-ring in the groove. This o-ring is important as it provides the
watertight seal between the housing and the cap.
STEP 6 Measure the new filter to be sure that it is the proper length (9 7/8”).
STEP 7 Place the new filter cartridge in the housing and carefully screw into
place.
HAND TIGHTEN ONLY!!
STEP 8 Tighten all connections. (On prefilter replacement, disconnect the red
feed line at membrane housing). Open the water supply valve. (On
prefilter replacement only, allow water to run from the red line until you
get a steady stream of water). Reconnect line to housing and inspect all
connections for leaks.
STEP 9 Turn storage tank valve on. Allow water to flow from RO faucet until it
runs clear. Close faucet. System is now ready to use.
The expected life of this equipment is approximately Ten (10) years
dependent on local water conditions including but not limited to minerals,
additives and water pressure.
Note: The filter assembly should be protected against freezing to avoid
expansion, cracking, and a subsequent leakage.
