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 110 volt, 60 Hertz current supply is required. Make certain the current supply is always hot and cannot be turned off with another switch. (Other voltages available.)

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 100˚ 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 4 feet apart for twin units.)

2. All plumbing should be done in accordance with local plumbing codes. The pipe size for the drain line should be the same size as the drain line ﬂow control female 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. Solder joints near the drain must be done prior to connecting the Drain Line Flow Control ﬁtting. Leave at least 6″ between the DLFC and solder joints when soldering when the pipes are connected on the DLFC. Failure to do this could cause interior damage to the DLFC.

4. Teﬂon tape is the only sealant to be used on the drain ﬁtting. The drain from twin units may be run through a common line.

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

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

7. On units with a by-pass, 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.

8. Place the by-pass in service position.

9. Manually index the softener control into “service” position and let water ﬂow into the mineral tank. When water ﬂow stops, open a cold water tap nearby and let run until air pressure is relieved.

10. Electrical: All electrical connections must be connected according to codes. Use electrical conduit if applicable. Remote meter systems and Twin meter system wiring diagrams are on page 25. Plug into power supply.
