Installation

All plumbing must conform to local codes. The two tanks should be plumbed to an interconnecting manifold, Figure 6. It is highly recommended that separate brine lines be used for each tank. It is critical for the resin, resin volume, inlet piping, etc. to be identical for both tanks.

WARNING: Do not use tools to tighten plastic fittings. Over time, stress may break the connections. Hand tighten the nuts.

WARNING: Do not use petroleum grease on gaskets when connecting bypass plumbing. Use only 100% silicone grease products when installing any Autotrol brand valve. Non-silicone grease may cause plastic components to fail over time.

WARNING: The inlet water must be connected to the inlet port of the valve. When replacing non- Autotrol valves, the inlet and outlet may be reversed. Ensure that the plumbing is not installed in the oppposite order. Tank media may be pushed into the valve.

WARNING: Filter media may need to be properly conditioned before the filter is placed into full operation. Consult the original equipment manufacturer for proper procedure.

Location Selection

The following considerations must be taken into account when selecting the location for the water conditioning system.

•Locate the system as close to a drain as possible.

•If supplementary water treating equipment is required, make sure that adequate additional space is available. Locate the brine tank in an accessible place so that salt can be easily added.

•Do not install any system with less than 10 feet

(3 m) of piping between the outlet of the conditioners and the inlet of the water heater. Water heaters can transfer heat down the cold water pipe into the control valve. Hot water can severely damage the conditioners.

Aten-foot (3-m) total pipe run (including bends, elbows, etc.) is a reasonable distance to prevent hot water damage. A positive way to prevent hot water from flowing from a heat source to the conditioners is to install an expandable accumulator tank before the hot water heater. Always conform to local codes.

•Do not locate the unit in an area where the ambient temperature is ever below 34oF (1oC) or over 120oF (49oC).

•Maximum allowable water temperature is 100oF (38oC).

•Do not install the unit near acid or acid fumes.

•Do not expose the unit to petroleum products.

Water Line Connection

A bypass valve system must be installed to accommodate occasions when the water conditioning system must be bypassed for supplying hard water or servicing. See Figures 7 and 8.
