Care and cleaning–Filter replacement procedures.

To obtain replacement filters, call GE Appliance Parts at 800-626-2002.

Pre/Post Filter Cartridge Replacements FX18P	Activated Carbon
Reverse Osmosis Cartridge Replacement FX18M	Thin Film Polyamide

You must replace the prefilter cartridge at least every six months to protect the Reverse Osmosis membrane from being destroyed by chlorine and/or from plugging with sediments in the water supply valve.

It is time to replace the Reverse Osmosis cartridge when the amber “RO” light, on the faucet base, flashes continually while Reverse Osmosis water is taken from the faucet.

To signal correct replacement interval for prefilter, postfilter and batteries, the amber “FILTER” indicator light, on the electronic faucet base, will begin to flash after six months, or 900 gallons of product water use, whichever occurs first.

Remove the Filters

Be sure you have cleaned your hands with anti-bacterial soap before handling inner parts of the system.

1 Turn water supply valve to the Reverse Osmosis system off; turn clockwise. Turn RO faucet on and allow tank to completely drain (this will take a few minutes).

NOTE: If the Reverse Osmosis Filtration System is connected to your icemaker, YOU MUST turn off the icemaker by raising the feeler arm before servicing the filter, changing the filters or purging the filtration system. After completing work, allow four hours for unit to refill, then lower the feeler arm to resume icemaking.

2 Pull the Reverse Osmosis system away from cabinet; leave tubing connected. Place a dry towel under the system.

3 Remove the clamp retainers and sections from top of unit.

4 Lift the Reverse Osmosis cap straight up (slight resistance is normal) from the Reverse Osmosis housing (no need to disconnect tubing) and move aside.

NOTE: If the cap o-ring remained in the Reverse Osmosis housing, replace it on the cap.

5 Remove the Reverse Osmosis cartridge and the outer prefilter cartridge from the Reverse Osmosis housing and place the Reverse Osmosis cartridge in a clean plastic bag. Discard the prefilter cartridge. Dispose of water from the Reverse Osmosis housing.

6 Turn off tank shutoff valve (red color).

7 Disconnect tubing at both ends of postfilter. Remove postfilter from holder and discard. Disconnect postfilter tube at tank shutoff valve. Retain postfilter tube.

8 Hold a container under tank shutoff valve. Open shutoff valve and drain water from tank. (Expect up to 1/2 gallon.)

9 Sanitize the system. Go to Sanitizing the RO System section and follow steps 1–8.
