OPTIONAL INSTALLATION

Connecting your Reverse Osmosis System to Refrigerator Icemaker / Water Dispenser

CAUTION:

  If you are connecting this unit to your refrigerator/icemaker with initial RO installation, wait to turn on the icemaker until 

the post-polishing filter has been flushed according to Step 11.

CAUTION:

 Use plastic tubing and fittings. Do not use copper tubing or brass fittings. 

NOTE:

  For optimum performance, it is recommended that the distance between the RO system and the refrigerator icemaker/water 

dispenser be no greater than 10 feet (3 m). At distances greater than 10 feet, the water pressure from the system may not be 

adequate to deliver water to the refrigerator. 

MATERIALS REQUIRED

 (available from your local hardware store):

•  3/8-inch x 3/8-inch x 3/8-inch (0.952 cm x 0.952 cm x 0.952 cm) compression or quick-connect tee
• 10 feet (3 m) of 3/8-inch (0.952 cm) polyethylene tubing
• Shut-off valve

1. Turn off refrigerator water supply and icemaker (consult manufacturer’s guidelines).
2. Close tank valve (on top of storage tank).
3. Turn off water to RO system at the cold water supply, or at the feed water supply adapter.
4. Open drinking water faucet to relieve pressure.
5.  Locate tubing (permeate) leading to your drinking water faucet. Cut and insert the

3/8-inch x 3/8-inch x 3/8-inch compression or quick-connect tee into the permeate tubing.

Consult manufacturer’s guidelines before installing the supply adapter.

NOTE: 

When cutting the permeate tubing, you may experience some water leakage.

6.   Using a length of 3/8-inch polyethylene tubing, connect the

icemaker/dispenser line with the free port on the compression tee.

7.  The shut-off valve should be installed as close to this port of the tee

as possible. Shut-off valve should be installed in the OFF position

Consult manufacturer’s guidelines before installing the shut-off valve.

8. Completely open cold water supply.
9. Open tank valve.

 10. Turn off the drinking water faucet.
