PE Tube Supplied with Reverse Osmosis System
STEP 1 – Install Cold Water Supply Fitting
Check and comply with your local plumbing codes before you start installation. Refer to the
Specifications and Dimensions page 3 for supply water requirements. The Water Supply
Fitting can be adapted to a 3/8” or ½” supply line with the enclosed adapter. See Figure 4
for more details.
INSTALL THE COLD WATER SUPPLY FITTING
1. As shown in Figure 4, the hot and cold water supply
shut-off valve can be located under the kitchen or
bathroom sink. Close both valves and open the sink
faucet to release any pressure in the water supply lines.
Make sure the sink faucet water has stopped flowing
before proceeding to the next step.
Note: Typically, the cold-water supply shut-off valve is
located on the right side. However, in order to ensure
this, please keep the hot water on for two minutes.
Feel the two hoses with your palm. The hot water
supply riser hose should be warm, and the other pipe
which is cold should be the cold-water supply pipe.
2. Before disconnecting the cold-water supply line, have a
bucket and towel ready to capture any water left-over in
the water supply line.
3. Disconnect the existing cold-water supply line from the
water shutoff valve and water faucet supply line.
4. Inspect the water supply fittings to make sure that the
gasket is inside the female threaded portion of the fitting.
5. Before installing the water supply fitting onto the
cold-water shutoff valve, be sure to wrap the threads with
thread-tape. Be careful not to cross thread or over-tight-
en.
6. Connect the existing cold-water line to the male
threaded portion of the water supply fitting and hand-tight-
en. Be careful not to cross thread or over-tighten. Once
threaded properly, tighten with an adjustable wrench.
7. When the water supply fitting is connected to the
cold-water supply, make sure the water shutoff valve is in
the closed position, refer to Figure 5.
8. Hold off on attaching the “white” PE tube to the water
supply fitting, this water connection will be made in Step 6
