Note:
Non-Air Gap Faucet – Comes with the system. (Air Gap may be purchased separately - part number H-
T5022.) Some states require the use of an air gap faucet. Check your local plumbing code to assure
compliance.
Note:
The plastic faucet bracket (included) may be used in locations where there is no countertop to
install the faucet onto.
3. Connect Tubing
Connect the other end of the yellow tubing to the elbow in the “out” end of the post
filter.
4. Additional Point of Use Connection (Optional)
To connect an additional point of use (icemaker, extra faucet, etc.), place an additional
tee connector in the ¼” yellow tubing line between the faucet and the outlet of the post-
filter. Ensure that all tubing and fittings used for RO product water are poly material, and not copper. Due to
RO product water being very pure, it can leach the minerals from copper tubing which will cause a metallic
taste in the water or ice and cause the copper tubing to develop pinhole leaks over time.
Turning the System On for the First Time
Make sure all water supply /drain lines are secure and free from leaks.
Slowly turn the feed valve counterclockwise until fully open (the handle should be in line with the tubing as it
enters the connection). Check the stem seal for leakage. If necessary, tighten stem nut lightly.
Turn storage tank valve one quarter turn counterclockwise to open the valve (the handle should be in line with
the tubing as it enters the connection).
Open the product water faucet and let the water flow until all the air has been expelled from the system. This
will take about an hour.
Close the product water faucet. In 30 minutes, check the connections for leaks and correct if necessary.
Do Not Use the First Two Reservoirs of Water
Allow the reservoir to fill for 4-6 hours. Dispense this water to drain. This process
removes the factory installed sanitizing solution from the entire system and sends it to the
drain. Repeat this process one more time. Allow the tank to fill for 4-6 hours and
dispense this water to the drain. Do not drink this water!
Note: Air bubbles may be present in the product water after initial system startup, causing a milky color in the
water. This is normal and safe to drink. The air bubbles will disappear within a few days of regular use.
