G. PREFILL AND SANITIZE THE STORAGE TANK
Prefilling the storage tank is always recommended so that there is pressure to check for leaks as well as sufficient water to flush the carbon postfilter. The SQC RO Drinking Water Appliance is furnished with a container of special sanitizing gran- ules. It is important to use a sanitizer when prefilling the tank.
1)Thread the taped 3/8" x 1/4" tank fitting into the tank valve. Do not over tighten. Open the tank valve so that the tank valve handle is parallel to the valve body. Locate the enclosed container of sanitizing granules, open it and pour the contents into the end of the tank valve.
2)Disconnect the 3/8" yellow tubing from the back of the purification assembly and connect one end of it into the tube fitting located on the tank valve.
3)Connect the other end of the 3/8" yellow tubing to the 3/8" x 1/4" union connector included in the tank sanitization kit.
4)Connect the free end of the 1/4" orange feed water tubing to the other end of the 3/8" x 1/4" union connector.
5)Open the feed water tapping valve (making sure the tank valve is still open) and allow the tank to fill (about 3 minutes).
6)Close the feed water tapping valve and the tank valve. Disconnect the 3/8" yellow tubing from the tank valve elbow fitting and set the tank aside while proceeding with the rest of the installation (the sanitizatizing solution should be kept in the tank for at least 15 minutes).
NOTE: 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.
NOTE: If an alternate storage tank is used, it should be sanitized with household bleach
7)Reconnect the 3/8" yellow tubing to the back of the purification assembly. Reconnect the 1/4" orange tubing to the feed water fitting on the purification assembly.
The drain saddle should always be installed above (before) the trap and on the vertical or horizontal tailpiece. Never install the drain saddle close to the outlet of a garbage disposal because plugging of the RO drain line may occur. (See Fig. 4)

1)Position the threaded half of the drain saddle at the selected location and mark the pipe through the threaded opening.
2)Drill a 1/4" hole at the marked location through one side of the drain tailpiece.
3)Position both halves of the drain saddle on the drain pipe so that the threaded opening is lined up with the hole in the drain pipe.
4)Use the screws and nuts to clamp the drain saddle onto the drain pipe. Make sure that there is equal space between saddle halves on each side. Do not overtighten. (See Fig. 5)
5)Orient the elbow in the direction of the RO faucet location.
IMPORTANT: After the installation is complete, it is recommended that the 3/8" x 1/4" union connector be saved for future use in tank sanitization.
H. INSTALL THE DRAIN CONNECTION
IMPORTANT: Before starting this procedure, inspect the condition of the drain piping, especially in older homes where the traps and tailpieces can be deceptively thin and frail. If they are in poor condition, it is wise to inform the customer that the condition should be remedied.
IMPORTANT: Some local plumbing codes may prohibit the use of

IMPORTANT:
Hole should be located on top of the pipe if drain saddle is positioned horizontally.
