16Step F - Connect TubesHOW TO CUT AND CONNECT THE TUBESYour Reverse Osmosis system includes push-in fittingsfor quick tubing connection. Review the followinginstructions before connecting the tubes in the nextstep. Failure to follow these instructions may lead tofuture leaks.Cut tubes to length1. Use a sharp cutter or knife to cut the end of tubing.Always cut the tubing square. See Fig. 19.2. Inspect the tube up to 1” from the end to be surethere are no nicks, scratches or other rough spots. Ifneeded, cut the tubing again. See Fig. 19.NOTE: Tubing lengths should allow for theremoval of the assembly from the hanger wash-ers for servicing. If tubing lengths are shortenedfor neater appearance, it may be necessary tokeep the assembly on the hanger washers forservice.Connect tubesNOTE: Remove protective foam plugs before con-necting tubes (See Fig. 18). Discard foam plugs.1. Push tubing through collet, until it engages the o-ring. See Fig. 20. Continue pushing until the tubebottoms out against the back of the fitting. See Fig.21. Do not stop pushing when the tube engages theo-ring. Failure to follow these instructions may leadto future leaks. When a 1/4” tube is fully engaged,11/16” of the tube has entered the fitting. When a3/8” tube is fully engaged, 3/4” of the tube hasentered the fitting. Mark tube with a piece of tape ormarker. See Figs. 20 & 21.2. If additional tubing is required, see parts list at theend of this manual.To Disconnect Tubes1. Push the collet inward with a finger tip. See Fig.23.2.
