SECTION 2: INSTALLATION
WATER LINE CONNECTION
A bypass valve system should be installed on all water conditioning systems. Bypass valves isolate the condi-
tioner from the water system and allow unconditioned water to be used. Service or routine maintenance proce-
dures may also require that the system is bypassed.
CAUTION: The inlet water must be connected to the inlet port of the valve. When replacing other makes
of valves, the inlet and outlet may be reversed. It is also possible for the plumbing to be installed in an
opposite order. Do not solder pipes with lead-based solder.
CAUTION: Do not use tools to tighten plastic fi ttings. Over time, stress may break the connections.
When the bypass valve is used, only hand tighten the nuts.
CAUTION: Do not use petroleum grease on gaskets when connecting bypass plumbing. Use only 100%
silicone grease products. Non-silicone grease may cause plastic components to fail over time.
DRAIN LINE CONNECTION
NOTE: Standard commercial practices are expressed here. Local codes may require changes to the fol-
lowing suggestions. Check with local authorities before installing a system.
1) The unit should be above and not more than 20 ft (6.1 m) from the drain. Use an
appropriate adapter fi tting to connect 1/2 inch (1.3 cm) plastic tubing to the drain
line connection of the control valve.
2) If the backwash fl ow rate exceeds 5 gpm (22.7 lpm) or if the unit is located 20 - 40
ft (6.1 - 12.2 m) from drain, use 3/4 inch (1.9 cm) tubing. Use appropriate fi ttings
to connect the 3/4 inch tubing to the 3/4 inch NPT drain connection on valve.
3) The drain line may be elevated up to 6 ft (1.8 m) providing the run does not exceed
15 ft (4.6 m) and water pressure at the conditioner is not less than 40 psi. Eleva-
tion can increase by 2 ft (61 cm) for each additional 10 psi of water pressure at
the drain connector.
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. Where the drain empties into an overhead sewer, a sink-type trap must be
used. Secure the end of the drain line to prevent it from moving.
CAUTION: Never insert drain line directly into a drain, sewer line or trap. Always allow an air gap be-
tween the drain line and the wastewater to prevent the possibility of sewage being back-siphoned into
the conditioner.
In the event of a malfunction, the BRINE TANK OVERFLOW will direct “overfl ow” to the drain instead of spilling
on the fl oor. This fi tting is located on the side of the brine tank.
Do not elevate overfl ow line higher than overfl ow fi tting.
Do not tie into drain line of control unit. Overfl ow line must be a direct, separate line from overfl ow fi tting to drain,
sewer or tub. Allow an air gap as per drain line instructions.
