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 20.
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 OVER TIGHTEN. 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 up, 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 fill and empty the storage tank two (2) times. 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
20.
