Installation Continued
6. Connecting the Faucet to the Drain
NOTE:
THIS IS A GRAVITY DRAIN LINE. ANY LOOPS, KINKS OR SHARP BENDS MUST
BE ELIMINATED BEFORE PROCEEDING. FAILURE TO CREATE A STRAIGHT LINE
TO THE DRAIN MAY RESULT IN REJECT WATER LEAKING THROUGH THE AIR
GAP IN THE FAUCET ONTO THE COUNTERTOP AND BELOW THE FAUCET.
(A)
Align the white 3/8-inch tubing from the faucet with the compression nut on the drain
clamp. Create as straight a path as possible with the tubing. Cut the tubing squarely below
the nut and remove the internal and external burrs.
(B)
Loosen the compression nut two complete turns. Insert the tubing into the nut until it
stops. Tighten with fingers, then tighten 1 to 2 turns with a wrench.
7. Installation of Mounting Screws
(A)
If system is being installed under the kitchen sink, locate it on back or right wall. Make
sure to allow ample space for installation. To change the filter cartridges, a minimum of 1
inches of clearance is required underneath the filter housings. A minimum of 2-inches of
clearance from the left side of the unit is also required or six inches from the left bracket
mounting screw hole. Install mounting screws at least 13
5 ⁄ inches apart. Leave 5/16-inch space between the head of the screw and the wall to slip
3
4
bracket onto screws.
8. Connecting the Faucet to the System
(A)
Locate the red tubing (reject water line) from the drinking water faucet. Place a mark on
the red tubing 5/8-inch from the end. Moisten the end of the tubing with water and insert
tubing into the red quick-connect fitting found behind the membrane (middle) housing.
Insert tubing until the mark is flush with the quick connect opening.
(B)
If desired, use the 1/4-inch elbow included with the installation kit. This elbow can be
pressed in for installations in situations where room is not available to bend the tubing.
This elbow fitting can also be swiveled. Locate the 1/4-inch fitting with the blue quick-
connect collar on the left hand side of the RO system. Align the blue tubing from the
faucet with the quick-connect fitting on the RO system. Place a mark on the blue tubing
5/8-inch from the end. Moisten the end of the tubing with water and insert until the mark is
flush with the quick-connect opening. If tubing is not firmly connected, leaking will occur.
It is important for the tubing to be inserted all the way until the mark is flush with the outer
edge of the quick-connect insert.
NOTE:
Tubing may be quickly and easily removed from the fitting if necessary by
pressing in the collar around the fitting while pulling the tubing with your other
hand.
9. Connecting the Storage Tank to the System
CAUTION:
When tank is full, it weighs approximately 40 lbs. Provide ample support under the
tank.
(A)
Remove the black protective cap to expose the 1/4-inch threaded opening at the top of the
tank.
(B)
Thread the tank valve onto the top of the tank opening by turning it clockwise until snug.
(C)
Locate the green tubing. Place a mark on the green tubing 3/4-inch from each end.
Moisten one end of the green tubing with water and insert with a twisting motion into the
free port of the tank valve until the 3/4-inch mark is flush with the quick connect fitting.
(D)
Install free-end of green tubing to green quick-connect fitting or elbow as directed in step
9C.
NOTE:
Do not cut green tube. This line should be left at the pre-cut length for future service.
(E)
Place entire system over mounting screws on wall and slide down.
CAUTION:
Make certain system is firmly attached to wall to prevent it from falling and
possibly becoming damaged.
NOTE:
Use caution not to bend or pinch the tubing behind the system while attaching
to mounting screws.
NOTE:
The pressurized storage tank has a capacity of 1.9 to 3.2 gallons. The tank's air
pressure is factory set at 5 to 7 psi when tank is empty.
