IMPORTANT SAFEGUARDS

!

Control Valve

•  This glass-filled Noryl (or equivalent) fully automatic control valve 

is designed as the primary control center to direct and regulate all 

cycles of a water softener or filter. 

•  The control valve, fittings, and/or bypass are designed to 

accommodate minor plumbing misalignments but are not 

designed to support the weight of a system or the plumbing. 

•  The nuts and caps are designed to be unscrewed or tightened 

by hand or with a special plastic wrench. If necessary pliers can 

be used to unscrew the nut or cap. Do not use a pipe wrench to 

tighten or loosen nuts or caps. Do not place a screwdriver in the 

slots on caps and/or tap with a hammer. 

•  After completing any valve maintenance involving the drive 

assembly or the drive cap assembly and pistons, unplug the 

power source jack from the printed circuit board (black wire) then 

plug it back in or press and hold NEXT and REGEN buttons for  

3 seconds. This resets the electronics and establishes the service 

piston position. The display should flash all wording, next 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.

 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 closed 

crates, cartons, and other packaging, and inspect for concealed 

damage. The manufacturer is not liable for any damage 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 affects the performance of 

the system.

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

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

tank. Tighten if necessary.
The 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 – 110°F (4°C – 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.

Softener should be located at least 10 feet away from hot water 

heater to protect against hot water back-up.

When piping with copper, solder all piping as subassemblies 

before installing. Internal damage can result from the high heat of 

the torch.
It is recommended that manual isolating valves be installed on 

the inlet and outlet piping along with a system bypass valve. This 

isolates the unit when service is required. Run drain line to a sump, 

drain trench, or other open drain. Open drains are required for 

taking samples and allowing a visual check. Avoid overhead pipe 

runs to drain facility, as undue backpressure affects the operation 

of injectors.

All piping is to meet your local and state codes. 

AVOID CROSS 

CONNECTIONS!

Position brine tank approximately 6" from the softener tank on a 

smooth surface.
Connect the brine air check assembly in the salt/brine tank to the 

brine suction (eductor) connection. If brine tank is located more 

than 6 feet from softener tank, use one size larger tubing. Tubing 

5

8

" should be installed from the brine tank overflow to drain. This is 

a gravity drain designed to divert brine to the drain in the event of a 

malfunction, which would cause overflow of the brine tank.
Be sure inlet/outlet isolating valves are closed and bypass valve is 

open.

Do not exceed water pressure of 120 psi (8.2 bar). Do not 

exceed 110°F (43.3°C). Do not subject unit to freezing 

conditions.
