SAFETY INFORMATION
This water conditioner’s control valve conforms to UL/CE
Standards. Generic valves were tested and certified for
compliance as verified by the agency listing.
• Please review the entire Installation and Operation
Manual before installing the water conditioning system.
• As with all plumbing projects, it is recommended that
a trained professional water treatment dealer install
the water conditioning system. Please follow all local
plumbing codes for installing this water conditioning
system.
• This system will not make microbiologically unsafe water
safe. Water that is unsafe must be treated separately
from this conditioner.
• This water conditioning system is to be used only for
potable water.
• Inspect the water conditioning system for carrier shortage
or shipping damage before beginning installation.
• Use only lead-free solder and flux, as required by
federal and state codes, when installing soldered copper
plumbing.
• Use caution when installing soldered metal piping near
the water conditioning system. Heat can adversely affect
the plastic control valve and bypass valve.
• All plastic connections should be hand tightened. Teflon ®
tape may be used on connections that do not use an
O-ring seal. Do not use pipe dope type sealants on the
valve body. Do not use pliers or pipe wrenches.
• Do not use petroleum-based lubricants such as Vaseline,
oils or hydrocarbon-based lubricants. Use only 100%
silicone lubricants.
• Use only the power transformer supplied with this water
conditioning system.
• All electrical connections must be completed according to
local codes.
• The power outlet must be grounded.
• Install an appropriate grounding strap across the inlet and
outlet piping of the water conditioning system to ensure
that a proper ground is maintained.
• To disconnect power, unplug the AC adapter from its
power source.
• Observe drain line requirements.
• Do not support the weight of the system on the control
valve fittings, plumbing, or the bypass.
• Do not allow this water conditioning system to freeze.
Damage from freezing will void this water conditioning
system’s warranty.
• Operating ambient temperature: 34° to 120°F (1° to
49°C).
• Operating water temperature: 34° to 100°F (1° to 38°C).
• Operating water pressure range : 25 to 120 psi (1.38
to 8.27 bar). In Canada the acceptable operating water
pressure range is 25 to 100 psi (1.38 to 6.89 bar).
• Observe all warnings that appear in this manual.
• Keep the media tank in the upright position. Do not turn
upside down or drop. Turning the tank upside down or
laying the tank on its side can cause media to enter the
valve.
• Use only regenerants designed for water conditioning. Do
not use ice melting salt, block salt or rock salt.
During cold weather it is recommended that the installer warm
the valve to room temperature before operating.

HOW TO USE THIS MANUAL
This installation manual is designed to guide the installer
through the process of installing and starting up water
conditioning systems featuring the ProSense controller.
This manual is a reference and will not include every system
installation situation. The person installing this equipment
should have:
• Training on the ProSense control valve.
• Knowledge of water conditioning and how to determine
proper control settings.
• Adequate plumbing skills.
PRE-INSTALLATION CONSIDERATIONS
Water Pressure
A minimum of 25 pounds of water pressure is required for
regeneration valve to operate effectively.
Electrical Facilities
A continuous 115 volt, 60 Hertz current supply is required.
Make certain the current supply is always hot and cannot be
turned off with another switch.
Existing Plumbing
Condition of existing plumbing should be free from lime and
iron buildup. Piping that is built up heavily with lime and/or iron
should be replaced. If piping is clogged with iron, a separate
iron filter unit should be installed ahead of the water softener.
Location Of Softener And Drain
The softener should be located close to a drain.
Bypass Valves
Always provide for the installation of a bypass valve.
Tank and Probe Assembly
Use only 100% silicone lubricant on the probe O-rings
(Figure 2). Do not allow the lubricant to come into contact with
the probe pins. Install the probe assemblies into the tank and
secure with the locking clasp (Figure 3).
Important: The pins on the probes will only fit into the bulkhead
fittings one way. The pins must go into the matching holes at
the bottom of the fitting. The probe with the shortest length of
wire must be on top.
NOTE: Do not attempt to tighten or loosen the Bulkhead
fittings as they are secured with a locking
adhesive.
