Drain Line Connection
1. Ideally located, the unit will be above and not more than 20 feet (6.1 m) from the
drain. For such installations, use an appropriate adapter fitting (not supplied), to
connect 1/2-inch (1.3-cm) plastic tubing to the drain line connection of the control
valve.
2. If the unit is located more than 20 feet (6.1 m) from drain, use 3/4-inch (1.9-cm)
tubing for runs up to 40 feet (12.2 m). Also, purchase appropriate fitting to
connect the 3/4-inch tubing to the 1/2-inch NPT drain connection.
3. If the unit is located where the drain line must be elevated, you may elevate the
line up to 6 feet (1.8 m) providing the run does not exceed 15 feet (4.6 m) and
water pressure at conditioner is not less than 40 psi (2.76 bar). You may
elevate an additional 2 feet (61 cm) for each additional 10 psi (0.69 bar).
4. Where the drain line is elevated but empties into a drain below the level of the
control valve, form a 7-inch (18-cm) loop at the far end of the line so that the
bottom of the loop is level with the drain line connection. This will provide an
adequate siphon trap.
5. Where the drain empties into an overhead sewer line, a sink-type trap must be
used.
IMPORTANT: Never insert drain line into a drain, sewer line or trap. Always
allow an air gap between the drain line and the wastewater to prevent the
possibility of sewage being back-siphoned into conditioner.

Brine Line Connection
It will be necessary to install the brine tube and line to a fitting installed on the air
check. Teflon
*
tape all threaded connections.
Be sure all fittings and connections are tight so that premature checking does not
take place. Premature checking is when the ball in the air check falls to the bottom
before all brine is drawn out of the brine tank. See Placing Conditioner into
Operation section.
