Prefilter, Postfilter and Reverse Osmosis Membrane Cartridge Replacement Procedure
When the amber filter light in the faucet base
flashes, it is time to replace the prefilter and
postfilter. This will occur every 6 months.
Be sure to wash your hands before handling
inner parts of the system.
1. Turn OFF the icemaker (if attached to
the system).
2. Turn off water supply to the system.
3. Turn ON faucet to drain tank (may take several
minutes). Turn OFF faucet when tank is empty.
4. Remove the prefilter, postfilter and Reverse
Osmosis cartridge by rotating to the left about
1/3 turn.
5. Follow Sanitizing the Reverse Osmosis System
procedure found on page 19.
6. Remove foil on top of new replacement
cartridges. Install new cartridges into the
manifold by turning to the right about 1/3 turn
until the alignment marks line up and the
cartridges stop. DO NOT OVERTIGHTEN. The
cartridges will rise up as they are turned.
NOTE: The prefilter and postfilter are identical.
You may install either filter in the prefilter or
postfilter position. The reverse osmosis cartridge
is installed in the center position.
7. Turn ON water supply to fill the system
(may take up to four hours). Check for leaks.
8. Remove the battery tray and replace the
battery, positive “+” side down, to reset timer
and monitor function in faucet base (see Battery
Installation for proper procedure).
NOTE: Allow at least 90 seconds to elapse before
installing new battery. This will ensure a full
electronic reset and proper operation for the
next 6 months.
9. If only the prefilter and postfilter are replaced,
turn the faucet ON and empty the filled storage
tank. If the membrane cartridge is replaced, fill
and empty the storage tank a total of four times.
(This will remove the food grade preservatives
contained in new membranes. This preservative
will give product water an unpleasant taste
and odor.)
10. Once the storage tank is full, turn on the
icemaker.
NOTE: System should be sanitized when replacing
the prefilter and postfilter cartridge or the Reverse
Osmosis cartridge. Follow the Sanitizing the Reverse
Osmosis System procedure on page 19.
