SPECIFICATION
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.
*Choose HIGH EFFICIENCY to minimize salt usage. Your system will
regenerate a little more often but your salt usage can be reduced by
20% compared to the STANDARD setting. Choose STANDARD when
you need to maximize your capacity but still operate the system with
good efficiency. Choose ** IRON & MN if you have problem water
containing Iron, Manganese or hardness in excess of 50 gpg. The high
salt setting will be needed since these minerals are more difficult to
clean out of the resin bed. Note: A resin cleaner will also need to be
periodically added to the brine tank to insure proper operation.
See page 25: Res-Up® Feeder Installation Instructions
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
**Maximum Iron = 2.0 ppm ferrous (clear water iron)
Maximum Hydrogen Sulfide = 0.0 ppm
Maximum Manganese = .75 ppm
pH = 6.5 to 8.5 with no iron present with iron present
6.5 - 7.5
CAUTION!
Do not use where the water is microbiologically
unsafe or with water of unknown quality without
adequate disinfection before or after the unit.
**NOTE
SET HARDNESS
This value is the maximum
compensated water hardness in
grains per gallon of the raw water
supply. It is used to calculate the
system capacity. If Ferrous Iron is
present add 4 gpg for every 1 ppm
of Ferrous Iron, 8 gpg for
Ferrous Manganese.
