Installation Instructions Cont’d
1. Position the conditioner on a flat surface, near a drain and a 115 volt AC outlet. The unit is provided with a 24V
adapter.
2. Study the layout of the present water lines and drains in order that you can determine the best location for your water
conditioner and plan your installation. Your conditioner must not be subjected to freezing or to water temperatures
above 110°F which will void the warranty.
3. All plumbing should be done in accordance with local plumbing codes. The pipe size for the drain line should be a
minimum of 1/2”. However, a 3/4” drain line is required where backwash flow rates are in excess of 7 gpm or the
length of the drain line is greater than 20 feet.
4. Soldering joints near the drain must be done prior to connecting the drain line flow control (DLFC). Leave at least 6”
between the DLFC and the solder joints when soldering pipes that are connected on the DLFC. Failure to do this
could cause interior damage to the DLFC.
5. Teflon tape is the only sealant to be used on the drain fitting.
6. Make sure that the floor is clean and level beneath the salt storage tank.
7. Place approximately 1” 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.
8. On units with a bypass, place in BYPASS 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. Once clean, close the water tap.
9. Place the bypass in the SERVICE position and let water flow into the mineral tank. When water flow stops, slowly
open a cold water tap nearby and let run until the air the air is purged from the unit.
10. Plug unit into an electrical outlet. NOTE: all electrical connections must be connected according to local codes.
