1 - PREPARE FOR INSTALLATION:

Check the Following: Main Water Supply Line, Drain Access, Electrical Outlet, and Clearances to comlepte the install.

Location of Tank: Units can be installed, almost anywhere. Inside or outside. However, use your common sense. Valves may be

water resistant, not water proof. Protect any system from the elements. Review issues on water flow rates and pressure, and envi-

ronmental and water temperature ranges. The tank should have access to the supply water, provide filtered water to the home, be

located close to a clean working drain, have an electrical outlet available, and be connected according to all local plumbing codes.

Water Temperature Range: Feed water temperature not to exceed 110°F or be allowed to go below 40°F. Protect unit from

exceeding high temperatures and direct sunlight, and never allow unit, the drain line and any water to freeze.

Electrical: An uninterrupted alternating current (A/C) supply is required. The system is ideally located within 4-6 feet of a 110 volt

outlet to allow the unit to be plugged in. A 24 volt motor and transformer is available for longer electrical runs (use 10-2 regular

lamp gauge wire). The 24 volt transformer must be located inside.

Existing Plumbing: Condition of existing plumbing should be free from lime and iron buildup. Piping that is built up heavily and

clogged with lime and/or iron should be replaced. Problem with iron? Our separate iron filter unit should be installed ahead of

any other unit. Old galvinized or combinations of plumbing materials can cause water issues and conditions.

Drain Connection: Nominal drain line and drain size should be a minimum of 1/2". **Backwash flow rates of 7 GPM (1354 units) with

drain line exceeding 20' in length require 3/4" line and drain. Install, non-restrictive, check valve in drain line, if drain water is expected

to flow over 5' above the height of the drain port. Never restrict the backwash drain water flow.Teflon tape is the only sealant to be used

on the drain fitting.

Check Incoming Water Pressure and Flow Rates: A minimum of 35 PSI and 8 GPM is required for backwash valve to operate

effectively. Water pressure not to exceed or to surge in excess of a maximum of 75 PSI for the system. Unsure of pressure or it's ability

to surge? A pressure reducing valve (PRV), or limiting pressure to 75 PSI is recommended for this and many other kitchen and bath

products in your home. Automatic valve is rated for 100 PSI and the tank is rated for 150 PSI, however the overall system with various

connections has limitations to excessive pressure. Water pressure measuring 75 PSI during the day may surge to over 100 PSI at

night when the automatic backwash occurs.

Install (often required by code) a pressure regulator (PRV) if the water pressure exceeds or can surge above 75 PSI.

2 - UNBOX UNIT: CHECK TANK AND VALVE AND LOCATE BYPASS AND MALE YOKE:

1) PLACE THE TANK WHERE YOU WANT TO INSTALL THE UNIT.

•

Make sure the tank is level and on a firm base. Black bases on tanks are glued-on and self-leveling. If necessary, lift tank - tap

base to floor - on the bottom side, in order to level unit. Take note of the clearances necessary to complete the installation.

2) CHECK AND TIGHTEN VALVE HEAD ON THE TANK.

•

Hand Tighten the Valve Head in a Clockwise Direction. Make sure the stainless tank cover or plastic dome (1354 units) does

not interfere or cut into the connections. Stainless covers are non-functional, if "dinged" in handling, turn to good side.

3) CONNECT BYPASS VALVE AND MALE YOKE TO VALVE HEAD.

•

Make sure bypass valves are facing up. Keep bypass valve level (horizontal). Do not put, upward or downward, pressure on

bypass valve, this will not allow nipples and o-rings to seat squarely and completely.
