Installing Tubing Into Fittings
Push the tube into the fitting and up to the
tube stop
Pull on the tube to check that it is secure.
Test the system before use.
Cut the tube square and remove burrs
and sharp edges. Ensure that the out-
side diameter is free from score marks.
For soft or thin walled plastic tubing we
recommend the use of a tube insert.

Installing Tubing Connections
With all components in place, complete final tubing
connections using these guidelines:
Tubing should follow contour of the cabinets
Cut tubing to desired length using square cuts and
proper cutting device
Make no sharp bends
Keep tubing from the post-filter to the faucet as
short as practical for good flow.
Leave enough tubing that the system can easily be
pulled out from the cabinet for easy filter changes.

2. Connect 3/8” tubing from tank to RO unit.

Sanitize System
Sanitize the System (Recommended)
Sanitizing is recommended immediately after installation of the Reverse Osmosis system. It’s also recom-
mended after servicing inner parts. It is important that the person installing or servicing the system have clean
hands while handling inner parts of the system.
1. Turn off the water supply to the RO system and close the ball valve on the storage tank.
2. Open the RO faucet.
3. Use an eyedropper (not included) and common household bleach (5.25%).
4. Add 3 ml. of bleach into open end of 3/8 tube connected to tank. Handle bleach according to bleach
manufacturer’s recommendations.
5. Connect tubing back to tank ball valve.
6. Sanitizing the system will be completed during the Flush System and Check Operation steps on the follow-
ing page.
Note: The bleach must be removed from the system before drinking the water. See Flush System instructions
on the next page.
