Maximum operating temperature 110°F (43.3°C); Electrical requirements 110V/60Hz (220V/50Hz); Operating pressure 20-100 psi. All types water softener
salt may be used (See MAINTENANCE). Specifi cations subject to change without notice.
NOTES:
1) Meter Initiated Softeners: Dial settings based on this capacity. Consult dealer before changing salt dosage.
2) Actual capacity may vary substantially depending on water analysis and operating conditions. Softening capacities for systems containing 1.0 cubic feet
and larger are based on Radium 226/228, Barium and Softening.
3) For satisfactory performance indicated fl ow rates and duration should not be exceeded. Flow rates specifi ed are adequate for normal residential applica-
tions. Do not use Service Flow Rate when sizing commercial applications or if treated water is to supply a geothermal heat pump, swimming pool, etc.
(contact dealer before selecting equipment).
4) For system to operate properly, pumping rate of well pump MUST be suffi cient to backwash unit at rate specifi ed.
