Prefilter, Postfilter and Reverse Osmosis Membrane Cartridge Replacement Procedure

Tips Installation Instructions Operating Instructions Safety

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.

ON

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.

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.
