INSTALLATION

12
STEP 1

Prepare the Appliance

Remove all packaging or installation materials from brine cabinet.
STEP 2 Prepare the Placement Area
1. Ensure the placement area is clean.
2. Turn off electricity and water supply to the water heater. For gas water heaters, turn the
gas cock to "Pilot".
3. Examine inlet plumbing to ensure that the pipe is not plugged with lime, iron, or any
other substance. Clean or replace plugged plumbing.
NOTICE (FOR WELL WATER ONLY): A minimum 3/4" pipe is required between the pressure tank and the
water softener for it to function properly. This note does not apply to city water, only to well water.
Ensure inlet/outlet and drain connections meet the applicable state and local codes.
Check arrows on bypass valve to ensure the water flows in the proper direction.
(see Bypass Valve Overview)
NOTICE: Do not install water softener backwards.
STEP 3 Turn Off Water Supply
1. Turn off the water supply.
2. Open the hot and cold water taps to depressurize the lines.
Place water softener in desired location using the system configuration diagram as a guide.
The diagram applies to a basement, slab, crawl space, and outside installations.
For most installations, install appliance after the pressure tank and any water filter appliance
or water meter; and before the water heater unless otherwise recommended. When
installing additional filters, such as a carbon filter for well water, place the filter after any
water conditioning appliance unless otherwise recommended.
Water Heaters: If less than 10' (3 m) of pipe connects the water treatment appliance(s) to the
water heater, install a check valve between water treatment appliance and water heater as
close to the water heater as possible. An expansion tank may also be used. Ensure the water
heater has an adequately rated temperature and pressure safety relief valve.
NOTICE: It is strongly recommended to cover the unit if installed outdoors.
STEP 4 Connect Water Lines
Connect water lines in compliance with all state, local, building, plumbing, and electrical
codes. Valve connection fittings on the back of the unit are 1" MNPT. They can be connected
to your home's plumbing supply with a variety of connectors or fittings (sold separately). You
can plumb your softener to CPVC, PEX, or copper. If using copper fittings do not allow solder
torch to melt the plastic threads on valve.
