General and Commercial Installation Checklist
1. Place the softener tank where you want to install the unit.
.
NOTE:
Be sure the tank is level and on a firm base.
2. During cold weather it is recommended that the installer warm the valve to room temperature before
operating.
3. Perform all plumbing according to local plumbing codes.
— Use a 1/2” minimum pipe size for the drain.
— Use a 3/4” drain line for backwash flow rates that exceed 7 gpm or length that exceeds 20’ (6 m).
4. Both tanks must be the same height and diameter and filled with equal amounts of media.
5. The distributor tube must be flush with the top of each tank. Cut if necessary. Use only non-aerosol silicone
lubricant.
6. Lubricate the distributor o-ring seal and tank o-ring seal. Place the main control valve on one tank and the
tank adapter on the second tank.
. NOTE:
If required, solder copper tubing for tank interconnection before assembling on the main control valve
and tank adapter. Maintain a minimum of 1” distance between tanks on final assembly.
7. Solder joints near the drain must be done before connecting the Drain Line Flow Control fitting (DLFC).
Leave at least 6” (152 mm) between the DLFC and solder joints when soldering pipes that are connected on
the DLFC. Failure to do this could cause interior damage to DLFC.
8. Use only Teflon tape on the drain fitting.
9. Be sure the floor under the salt storage tank is clean and level.
10. Place approximately 1” (25 mm) of water above the grid plate. If a grid is not utilized, fill to the top of the air
check in the salt tank. Do not add salt to the brine tank at this time.
11. On units with a bypass, place in Bypass position.
— Turn on the main water supply.
— Open a cold soft water tap nearby and let water run a few minutes or until the system is free of foreign
material (usually solder) resulting from the installation. Close the water tap when water runs clean.
12. Place the bypass In Service position and let water flow into the mineral tank. When water flow stops, slowly
open a cold water tap nearby and let water run until air is purged from the unit. Then close tap.
Electrical
13. Make all electrical connections according to codes. Plug the valve into an approved power source. Do not
insert meter cable into the meter yet.
14. Tank one has control valve and tank two has adapter.
15. Look on the right side of the control valve, it has indicators showing which position the control valve is in
during Regeneration and which tank is In Service.
NOTE:
Make sure the meter cable is not inserted in the meter dome. Swing the timer out to expose the
program wheel (to swing timer out) grab onto the lower right corner of timer face and pull outward.
