EQUIPMENT INSTALLATION

General Warnings And Safety Information
Electrical
There are no user-serviceable parts in the AC adapter, motor,
or controller . In the event of a failure, these should be replaced .
• All electrical connections must be completed according to
local codes .
• Use only the power AC adapter that is supplied . If the AC
adapter is replaced use a Class II, 12 volt, 150 mA supply .
• The power outlet must be grounded and always on .
• To disconnect power, unplug the AC adapter from its
power source .
• Install an appropriate grounding strap across the inlet
and outlet piping of the water system to ensure proper
grounding is maintained .
Mechanical
• Do not use petroleum based lubricants such as vaseline,
oils, or hydrocarbon based lubricants . Use only 100%
silicone lubricants .
• All plastic connections should be hand tightened. Teflon
tape should be used on connections that do not use an
O-ring seal . Do not use pliers or pipe wrenches .
• All plumbing must be completed according to local codes .
• Soldering of the plumbing should be done before
connecting to the valve . Excessive heat will cause interior
damage to the valve .
• Observe drain line requirements .
• Do not use lead-based solder for sweat solder
connections .
• The drain line must be a minimum of 1/2-inch diameter.
Use 3/4-inch pipe if the pipe length is greater than
20 feet (6 m) .
• Do not support the weight of the system on the control
valve fittings, plumbing, or the bypass.
• It is not recommended to use sealants on the threads .
Use Teflon* tape on all NPT threads.

General
• Observe all warnings that appear in this manual .
• This system is not intended to be used for treating water
that is microbiologically unsafe or of unknown quality
without adequate disinfection before or after the system .
• Keep the unit in the upright position . Do not turn on side,
upside down, or drop . Turning the tank upside down will
cause media to enter the valve .
• Operating ambient temperature is between 34°F (1°C)
and 120°F (49°C) .
• Operating water temperature is between 35°F (1°F) and
100°F (38°C) .
• Working water pressure range is 20 to 125 psi
(1 .38 to 8 .61 bar) . In Canada the acceptable working
water pressure range is 20 to 100 psi (1 .38 to 6 .89 bar) .
• Use only salts designed for water softening . Acceptable
salt type is sodium chloride pellet salt .
• Follow state and local codes for water testing . Do not
use water that is micro biologically unsafe or of unknown
quality .
• When filling media tank, do not open water valve
completely . Fill tank slowly to prevent media from exiting
the tank .
• Always make modifications to house plumbing first.
Connect to valve last .
• Plastic parts and O-rings may be damaged by heat and
solvents . When constructing plumbing connections allow
heated parts to cool and protect parts from solvents .
System Recharge Cycles
Service (Downflow):
Untreated water is directed down through the resin bed and up
through the riser tube . The hardness ions attach themselves
to the resin and are removed from the water . The water is
conditioned as it passes through the resin bed .
When a recharge cycle starts, the softener goes through
seven cycles . During the recharge cycle the softener will allow
untreated water to bypass into the building .
1 . Backwash 1 (Upflow):
The flow of water is reversed by the control valve and
directed down the riser tube and up through the resin bed .
During the backwash cycle, the bed is expanded and debris
is flushed to the drain.
2 . Brine Draw (Downflow):
The brine draw cycle takes place during the slow rinse
cycle . The control directs water through the brine injector
and brine is drawn from the salt tank . Brine draw is
completed when the air check in the salt tank closes .
Slow Rinse (Downflow):
The brine is directed down through the resin bed and up
through the riser tube to the drain . The hardness ions are
displaced by sodium ions and are sent to the drain . The
resin is recharged during the brine cycle .
3 . Repressurize Cycle (Hard Water Bypass Flapper Open):
This cycle closes the flappers for a short time to allow the
air and water to hydraulically balance in the valve before
continuing the recharge .
4 . Fast Rinse 1 (Downflow):
The control directs water down through the resin bed and
up through the riser tube to the drain . Any remaining brine
residual is rinsed from the resin bed .
5 . Backwash 2 (Upflow):
The flow of water is reversed by the control valve and
directed down the riser tube and up through the resin bed .
During the backwash cycle, the bed is expanded and debris
is flushed to the drain.
6 . Fast Rinse 2 (Downflow):
The control directs water down through the resin bed and
up through the riser tube to the drain . Any remaining brine
residual is rinsed from the resin bed .
7 . Brine Refill:
Water is directed to the salt tank at a controlled rate, to
create brine for the next recharge .
