Installation Steps and Start-Up Procedures, Cont.
Connect Gravity Overflow Connection and Secure Brine Well
Into Proper Position
The gravity overflow line drains away excess water should
the tank fill with too much water or the appliance
malfunction.
A. Attach the overflow elbow to the cabinet by removing
the safety shutoff from the brine well. (See Figure 5.)
1. Place the elbow through the hole in the cabinet wall
and the hole in the brine well.
2. Screw the overflow nut onto the overflow elbow
and tighten. This will also hold the brine well in the
proper position.
3. Reassemble the safety shutoff into the brine well.
Note: Ensure that the elbow is in the down position.
B. Connect 1/2-inch I.D. tubing (size cannot be reduced)
between the overflow elbow and a floor drain, laundry
tub, or other suitable waste receptor. This tubing is not
supplied with the appliance. Ensure that the overflow
line ends at a drain that is at least 3 inches (8 cm) lower
than the bottom of the overflow elbow. Maintain a
minimum of 2-inch (5 cm) air gap between the overflow
line and the flood level rim of the waste receptor to
prevent back-siphoning. The gravity line cannot be run
overhead.

Elbow
The drain line carries away the backwash water as part of the regeneration cycle.
A. Connect the drain line to the drain end cap with a 5/8-inch I.D. tubing (supplied). The size
cannot be reduced.
Note: If the drain line is 25 feet (7.6 meters) or longer, increase the drain line to 3/4-inch I.D
tubing using the appropriate fittings. The end of the drain line must be equal to or lower in
height than the control valve.
Caution: The drain line must not be kinked, crimped, or restricted in any way.
B. Route the drain line to a floor drain, laundry tub, or other suitable waste receptor. Maintain a
minimum 2-inch (5 cm) air gap as with the overflow line. This drain line should make the
shortest run to the suitable drain.
C. The drain line may be elevated up to 8 feet (2.4 m) from the discharge on the appliance as
long as the water pressure in the system is 40 psi (2.8 bar) or more.
A. Place the bypass valve in the Bypass position.
B. Turn on the main water supply.
C. Open the nearest cold water faucet to flush the plumbing of any excess soldering flux, air, or
any other foreign material until the water runs clear.
