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 PWF controller.  

This manual is a reference and will not include every system 

installation situation. The person installing this equipment should 

have:

•  Training on the control valve.
•  Knowledge of water conditioning and how to determine proper 

control settings.

•  Adequate plumbing skills.

Control Valve Function and  

Cycles of Operation

The time clock control valve has two calendar options for 

regeneration frequency: 1. an option where the user can choose the 

number of days (1-99) between each backwash; and 2. a seven-

day option where the user can choose which day(s) of the week a 

backwash should occur.
The control valve uses no traditional fasteners (e.g. screws); instead 

clips, threaded caps and nuts and snap type latches are used. 

Caps and nuts only need to be firmly hand tightened because radial 

seals are used. Tools required to service the valve include one small 

blade screw driver, one large blade screw driver, pliers and a pair of 

hands. A plastic wrench is available which eliminates the need for 

screwdrivers and pliers. Disassembly for servicing takes much less 

time than comparable products currently on the market. Control 

valve installation is made easy because the distributor tube can be 

cut ½" above to ½" below the top of tank thread. The distributor 

tube is held in place by an o-ring seal and the control valve also has 

a bayonet lock feature for upper distributor baskets.
The AC adapter power pack comes with a 15 foot power cord and is 

designed for use with the control valve. The AC adapter power pack 

is for dry location use only. If the power goes out, only the time of 

day needs to be reset. All other values are permanently stored in the 

nonvolatile memory.

 

Installation Preview

Conduct a visual check of all equipment for any damage that may 

have occurred during shipment.

If there is obvious damage to any equipment, it should be noted 

on the carrier’s Bill Of Lading. Open and inspect the contents of all 

closed crates, cartons, etc. and inspect for concealed damage. The 

manufacturer is not liable for any dam-age during transit.
Position the equipment in its proper location, setting on a flat 

surface. Level equipment as required. Equipment out of plumb can 

exhibit poor flow characteristics, which will affect the performance of 

the system.

Units are shipped with media (resin & gravel), distributions tube, and 

control valve installed. Double-check the valve installation on the 

tank. Tighten if necessary.
Unit should be positioned with the valve control facing forward.
Check the main line water pressure. The softener is designed for a 

minimum of 20 psi and a maximum of 125 psi working pressure. If 

the line pressure exceeds this limit, a pressure-reducing valve should 

be installed.
Maximum allowable water temperature is 40°F (4°C) – 110°F (38°C). 

A 120vac 60 cycle electrical source must be available for operation 

of the controller.
Connect raw water supply line to the inlet valve connection. Connect 

treated water outlet to service line. It is suggested that the pipe size 

be equal or one size larger than the valve connection.

Installation Guidelines:
  

seconds. This resets the electronics and establishes the 

service piston position. The display should flash all word-

ing, then flash the software version  and then reset the 

valve to the service position. 

•  The control valve is compatible with a variety of 

regenerants and resin cleaners. The control valve is 

capable of routing the flow of water in the necessary paths 

to regenerate or backwash water treatment systems. The 

injector regulates the flow of brine or other regenerants. 

The control valve regulates the flow rates for backwashing, 

rinsing, and the replenishing of treated water into a 

regenerant tank, when applicable.

•  Control valve installation is made easy because the 

distributor tube can be cut ½” above to ½” below the top 

of tank thread. The distributor tube is held in place by an 

o-ring seal and the control valve also has a bayonet lock 

feature for upper distributor baskets.
