‘Push-In’ Tubing Connector This product is outfitted with user friendly ‘Push-In’ connectors. Proper use of the connectors is shown in the diagrams below. It is most important that the tubing selected for use with these connectors be of high quality, exact size and roundness, and with no surface nicks or scratches. If it is necessary to cut the tubing, use a plastic tubing cutter or sharp razor knife. Make a clean square cut.
7. Reconnect the 3/8” yellow tubing to the back of the filtration assembly. Reconnect the 1/4” orange tubing to the feed water fitting on the filtration assembly. IMPORTANT NOTES • If you encounter difficulty in removing the tubing from the tank, make sure the tank valve is closed and then cut the yellow tubing approximately 1” away from the tank valve fitting to relieve the pressure. Remove the 1” piece from the tank fitting.
How to Replace the Prefilter and Postfilter Cartridges 1. Close the feed water valve and tank valve, then partially drain the cooler reservoir. Wait five (5) minutes for the assembly to completely depressurize. 2. Twist the filter cartridge 1/4 turn to the left so that the ears on the cartridge are able to disengage from the head. Firmly pull the cartridge from the head. It may be necessary to twist the cartridge slightly from side to side to help free it. (See Illustration A, below.) 3.
