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.
