General Commercial Pre-Installation Check List

WATER PRESSURE: A minimum of 25 pounds of water pressure is required for regeneration valve to operate effectively.

ELECTRICAL FACILITIES: A continuous 115 volt, 60 Hertz current supply is required. (Other voltages available.) Make certain the current supply is always hot and cannot be turned off with another switch.

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 ﬁlter unit should be installed ahead of the water softener.

LOCATION OF SOFTENER AND DRAIN: The softener should be located close to a drain. BY-PASS VALVES: Always provide for the installation of a by-pass valve. CAUTION: Water pressure is not to exceed 120 p.s.i., water temperature is not to exceed 110° F, and the unit cannot

be subjected to freezing conditions.

INSTALLATION INSTRUCTIONS

1. Place the softener tank where you want to install the unit making sure the unit is level and on a ﬁrm base. (Maximum 7 feet apart for twin units.) To provide for expansion and contraction of plastic resin tanks and rigid plumbing loads, use FLEXIBLE FITTINGS at the valve.

2. Allplumbing should bedone in accordance with local plumbing codes. The pipe sizeforthe drain line should be the same size as the drain line ﬂow control connection. Water meters are to be installed on soft water outlets. Twin units with (1) one meter shall be installed on common soft water outlet of units.

3. Make sure that the ﬂoor is clean beneath the salt storage tank and that it is level.

4. Place approximately 1″ of water above the grid plate (if used) in your salt tank. Salt may be placed in the unitat this time.

5. Place in by-pass position. Turn on the main water supply. Open a 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.

6. Place the by-pass in service position.

7. Manually index the softener control into “service” position and let water ﬂow into the mineral tank. When water ﬂow stops, close inlet valve, place control in “backwash” position to relieve head of air, then graduallyopen inlet valve to purge remaining air in tank. Return control to “service” position.

8. Electrical: All electrical connections must be connected according to codes. Use electrical conduit if applicable. Plug into power supply.

DRAIN

INLET

Hard water enters at valve inlet  ﬂows thru service adapter piston for by-pass, and up thru coupling to regeneration valve inlet. Flow continues thru the regeneration valve piston down the distributor tube  thru the bottom distributor and up thru the mineral  around the piston and out the drain. If optional no hard water by-pass piston is used, water ﬂow to service outlet is prevented by an extension on the service outlet until the end of the rapid rinse cycle or brine tank reﬁll cycle, depending on options chosen.

Hard water enters at valve inlet  ﬂows thru nozzle and thru throat to brine valve to reﬁll the brine tank. Inlet ﬂow also continues down thru mineral to the bottom distributor. Conditioned water ﬂows up thru the distributor tube, around the piston and out the outlet. Note: An option is available to keep service valve in by-pass position until the end of brine tank reﬁll cycle.
