INSTALLATION INSTRUCTIONS WATER SOFTENERS

GENERAL INFORMATION

1. Operating pressure range is 30-100 psi. If pressures over 100 psi are encountered, a regulator must be installed.
NOTE: The control valve will not operate correctly if feeding into an atmospheric tank. A pressure control device
must be added to the outlet to maintain the minimum pressure.
2. Power requirements are shown on inside cover of the control valve. You can also tell by wire color on the motor.
Black wires are 115 volt. Yellow wires are 220 volt. Blue wires are 24 volt.
3. Standard units are designed to soften unheated water not to exceed 100F. Special valve assemblies are available
to handle heated water supplies exceeding 100 F. Consult factory if applicable.
4. Each softener tank is shipped with distributor manifold and control valve preassembled. Take care when uncrating
and erecting so that no items are damaged.
5. The distributor assembly has been shipped inside the fiberglass mineral tank. Check to make sure that there is no
damage to the riser pipe, baskets, laterals or hub (if applicable).
NOTE: A prefilter should be used on installations in which free solids are present
LOCATE SOFTENER
1. Select a location that is accessible and near a floor drain that has adequate carrying capacity to handle the
softener backwash flow (see specification table for flow rate). Allow a minimum of 24" above the tank for
loading media.
2. Erect the softener tank(s) on a concrete or other firm foundation and level.
3. Position the brine tank according to the illustration and supplementary brine tank information. Keep the brine tank
as close as possible to the softener tank(s).
Note: The distance between the softener and brine tanks will affect the brine injector performance, as the distance
increases the injector performance decreases. This may cause an inadequate regeneration. Maximum
recommended distance is 5 ft.
4. A grounded electric receptacle is required for the control valves.
