4. Carefully remove any remaining sealant from the service fixture hole.
5. Using the Teflon tape supplied, wrap two to three turns of tape on the male pipe
thread of the valve, and the tube fitting.
6. Put the threaded end of the fixture through the hole, orienting the valve as shown in
Figure 10-1. Using the silicone sealant, apply a bead of silicone on the outside
surface of the cabinet side, around the valve body. This will provide a pressure tight
seal around the valve body. Place the washer on the valve thread, and then install
the coupler. Holding the valve body in position, use a wrench or pliers to thread the
coupling on until the valve is captured on the side panel.
7. Thread the tubing connector onto the coupling until it can no longer be turned by
hand. Holding the coupling secure with a wrench or pliers, turn the tube fitting
approximately one more revolution, using pliers or a wrench. Orient the tube fitting
such that it is easy to access it with the incoming service tube.
8. Connect the ¼-inch O.D. service tube to the tube fitting by pressing the tube all the
way into the fitting, turning the tubing nut until hand tight, and then approximately
one more turn using pliers or a wrench.
Do not route the service tubing under the sash weight channel. Route the tubing
between the weight channel and the exterior side panel.
9. Make sure the service fitting in the Purifier is in the off position before pressurizing
the service line. Once pressurized, check the valve body, the coupling, and the tube
fitting for leaks. Tighten any leaking joints.
10. Reattach the side panel.
