Working Temperature:
This unit must be
operated at temperatures between 40°F and
110°F (4°C - 43°C).
Working Pressure:
This water softener
must be operated on pressures
between 30 psi to 125 psi. If the water
pressure is higher than 125 PSI, use a
pressure reducing valve in the water supply
line to the softener.
Voltage = 120V / 60 Hz
Pipe Size = 3/4” and 1”
• At the stated service flow rates, the
pressure drop through these devices will
not exceed 15 psig.
• The manufacturer reserves the right
to make product improvements which
may deviate from the specifications and
descriptions stated herein, without obligation to change
previously manufactured products or to note the change.
Peak flow rates intended for intermittent use only (10
minutes or less) and are for residential applications only.
Do not use peak flow rate for commercial applications
or for a continuous rate when treated water supplies are
geothermal heat pump, swimming pool, etc.
For satisfactory operation, the pumping rate of the well
system must equal or exceed indicated backwash flow rate.
All units come with plastic bypass
