INSTALLATION
Figure 1. Piping Diagram
Electrical Requirements:
The automatic control valve requires a constant power supply - 110V AC. We recommend a GFCI (ground fault circuit
interrupter) outlet within 5 feet of the softener. Extension cords are not recommended.
If water pipes are used to ground electrical system, you will need to install a jumper wire across the filter unit.

Instruction manual
Unpack the unit and place it at the location where you intend to install the unit.
Stand back and look at the softener to make sure it is standing straight up and not tilted to one side. Make sure your
chosen location will be fairly level, dry, and protected from possible freezing conditions. The softener can sit directly on
the floor and will not corrode. DO NOT set the softener or salt tank onto make shift platforms
as this can cause damage or may cause it to topple.
The system has 3 connections - an inlet, an outlet, and a drain line connection. If you are
looking at the back of the unit (fig 2A), the inlet is on the left side.
Warning:
Make sure that
you have correctly identified the inlet of the system. REVERSING THE CONNECTIONS WILL
RESULT IN RESIN BEADS BEING THROWN INTO YOUR HOME'S PLUMBING SYSTEM CAUSING
DAMAGE TO IT AS WELL AS THE SOFTENER.
The following pipe can be used for installing your new system - Copper, CPVC, and PEX are the most popular.
