PNVR18ZWH01 General Electric Water Filter System - Instructions

First I removed the round faucet handle, slide the black knob behind that opens and closes the water flow. Secondly dis-lodged the base of the faucet up from the electronic base. Little bit of pressure is required. If necessary use screw driver to prea. Carefull might break the plastic base of the faucet. Once removed, using adjustable wrench, remove the bottom and top nuts of the pipe connecting faucet. Remove the old gasket. Do not reuse this gasket as it will leak. Screw-in the new faucet with gasket to base with water pipe using 2 nuts and wrench. Tighten lower nut as hard as you can, but top nut that secures the base and faucet liver, make sure it is good enough. Position base and front of faucet exactly in middle, so that black knob falls exactly behind the faucet arm. Put base along with faucet back onto electronic base, slide in the black knob and finally put faucet arm(lever) straight down. If necessary, grease O-rings on faucet arm(lever) with silicon.
