6. Soldering of joints near the drain port must be done prior to
connecting the Drain Line Flow Control fitting (DLFC).
Leave at least 6" (15 cm) between the DLFC and solder
joints when soldering pipes that are connected on the
DLFC. Failure to do this could cause interior damage to the
DLFC.
7. Plumber tape is the only sealant to be used on the drain
fitting.
8. Make sure that the floor is clean beneath the salt storage
tank and that the tank is level.
9. Place approximately 1" (25 mm) of water above the grid
plate. If a grid is not utilized, fill to the top of the air check
(Figure 1) in the salt tank. Do not add salt to the brine tank
at this time.
CAUTION
If grid plate is used, cut air check height just below
the grid plate. This is critical on 6", 7", 8" and 9"
tanks. The brine refill water must come above the
grid plate and make contact with the salt.
10. On units with a bypass, place in bypass position. Turn on
the main water supply. Open a cold soft water tap nearby
and let run a few minutes or until the plumbing is free from
foreign material (usually solder) that may have resulted
from the installation. Once clean, close the water tap.
11. Slowly place the bypass in service position and let water
flow into the mineral tank. When water flow stops, slowly
open a cold water tap nearby and let water run until the air
is purged from the plumbing lines.
12. Plug the transformer into an electrical outlet.
NOTE: All electrical connections must be connected according
to local codes. Be certain the outlet is uninterrupted.

Electrical Connection
The controller operates on 12-volt DC power supply. Do not
operate the controller with a power supply other than the one
supplied by the manufacturer for this model. For installation
location assistance, see Transformer Port Location on page
32.
NOTE: The power source should be constant. Be certain
the power adapter is not on a switched outlet. Power
interruptions longer than eight hours may cause the
controller to lose the time setting. When power is restored,
the time setting must then be re-entered.
INSTALLATION
Water Pressure
A minimum of 20 psi (1.4 bar) of water pressure is required for
the regeneration valve to operate effectively.
Electrical Facilities
An uninterrupted power supply is required. The control uses a
transformer to supply 12 VDC. Please make sure your voltage
supply is compatible with your unit before installation.
Existing Plumbing
Condition of existing plumbing should be free from lime and
iron buildup. Piping that is built up heavily with lime and/or iron
should be replaced. If piping is clogged with iron, a separate
iron filter unit should be installed ahead of the system.
Location of System and Drain
You must have an air gap on the drain line to prevent back flow
of drain water into the system. A 2x the drain line pipe diameter
air gap is required with a minimum 1" air gap.

Installation Locations
FOR DRY LOCATIONS ONLY.
Bypass Valves
Always provide for the installation of a bypass valve if unit is not
equipped with one.
CAUTION
Water pressure is not to exceed 125 psi (8.6 bar),
water temperature is not to exceed 110°F (43°C),
and the unit cannot be subjected to freezing
conditions.
WARNING:
The system must be depressurized before
removing any connections for servicing.
Installation Instructions
1. Place the media tank where you want to install the unit.
Make sure the unit is level and on a firm base.
2. During cold weather, the installer should warm the valve to
room temperature before operating.
3. All plumbing should be done in accordance with local
plumbing codes. The pipe size for a residential drain line
should be a minimum of 1/2" (13 mm). Backwash flow rates
in excess of 7 gpm (26.5 Lpm) or drain line length in excess
of 20' (6 m) require 3/4" (19 mm) drain line. Commercial
drain lines should be the same size as the drain line flow
control.
NOTE: The tank should have the distributor tube installed
and have the proper amount of regenerant in place.
4. Refer to the valve spec sheet for cutting height of the
distributor tube.
5. Lubricate the distributor O-ring seal and tank O-ring
seal. Place the main control valve on tank. Note: Only use
silicone lubricant.
