Installation Instructions
WATER PRESSURE: A minimum of 20 pounds of water pressure (1.3 bar) is required for regeneration valve to operate
effectively.
ELECTRICAL FACILITIES: An uninterrupted alternating current (A/C) supply is required. Note: Other voltages are
available. 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 fi lter unit should be
installed ahead of the water softener.
LOCATION OF SOFTENER AND DRAIN: The softener should be located close to a drain to prevent air breaks and
back fl ow.
BY-PASS VALVES: Always provide for the installation of a by-pass 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.
Installation Instructions
Place the softener tank where you want to install the unit making sure the unit is level and on a fi rm base. 1.
During cold weather, the installer should warm the valve to room temperature before operating. 2.
All plumbing should be done in accordance with local plumbing codes. The pipe size for residential drain line should 3.
be a minimum of 1/2” (13 mm). Backwash fl ow rates in excess of 7 gpm (26 Lpm) or 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 fl ow control.
Refer to the dimensional drawing for cutting height of the distributor tube. If there is no 4.
dimensional drawing, cut the distributor tube fl ush with the top of the tank.
Lubricate the distributor O-ring seal and tank O-ring seal. Place the main control valve on 5.
tank. Note: Only use silicone lubricant.
Solder joints near the drain must be done prior to connecting the Drain Line Flow Control 6.
fi tting (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.
Tefl on tape is the only sealant to be used on the drain fi tting. The drain from twin tank units 7.
may be run through a common line.
Make sure that the fl oor is clean beneath the salt storage tank and that it is level. 8.
Place approximately 1” (25 mm) of water above the grid plate. If a grid is not utilized, fi ll to 9.
the top of the air check (Figure 1) in the salt tank. Do not add salt to the brine tank at this
time.
On units with a by-pass, place in by-pass position. Turn on the main water supply. Open a 10.
cold soft water tap nearby and let run a few minutes or until the system is free from foreign
material (usually solder) that may have resulted from the installation. Once clean, close the
water tap.
Slowly place the by-pass in service position and let water fl ow into the mineral tank. When 11.
water fl ow stops, slowly open a cold water tap nearby and let run until the air is purged from
the unit.
Plug unit into an electrical outlet. Note: All electrical connections must be connected 12.
according to local codes. Be certain the outlet is uninterrupted.
