GENERAL WARNINGS

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. 

HYDROCARBONS SUCH AS KEROSENE, BENZENE, GASOLINE, ETC., MAY DAMAGE PRODUCTS THAT 

CONTAIN O-RINGS OR PLASTIC COMPONENTS. EXPOSURE TO SUCH HYDROCARBONS MAY CAUSE THE 

PRODUCTS TO LEAK. DO NOT USE THE PRODUCT(S) CONTAINED IN THIS DOCUMENT ON WATER SUPPLIES 

THAT CONTAIN HYDROCARBONS SUCH AS KEROSENE, BENZENE, GASOLINE, ETC.

THIS WATER METER SHOULD NOT BE USED AS THE PRIMARY MONITORING DEVICE FOR CRITICAL OR 

HEALTH EFFECT APPLICATIONS

Do not use Vaseline, oils, other hydrocarbon lubricants or spray silicone anywhere. A silicone lubricant may be used on 

black o-rings but is not necessary.

The nuts and caps are designed to be unscrewed or tightened by hand or with the special plastic wrench. If necessary a 

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. 

Do not use pipe dope or other sealants on threads. Use Teflon tape on the threaded inlet, outlet and drain fittings. Teflon 

tape is not necessary on the nut connection or caps because of o-ring seals.
After completing any valve maintenance involving the drive assembly or the drive cap assembly and pistons unplug power 

source jack from the printed circuit board (black wire) and plug 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, then flash the 

software version  and then reset the valve to the service position.

All plumbing should be done in accordance with local plumbing codes. The pipe size for the drain line should be a 

minimum of ½”. Backwash flow rates in excess of 7 gpm or length in excess of 20’ require ¾” drain line.
Solder joints near the drain must be done prior to connecting the drain line flow control fitting. Leave at least 6” between 

the drain line control fitting and solder joints when soldering pipes that are connected on the drain line control fitting. 

Failure to do this could cause interior damage to the drain line flow control fitting.
When assembling the installation fitting package (inlet and outlet), connect the fitting to the plumbing system first and 

then attach the nut, split ring and o-ring. Heat from soldering or solvent cements may damage the nut, split ring or o-ring. 

Solder joints should be cool and solvent cements should be set before installing the nut, split ring and o-ring. Avoid getting 

primer and solvent cement on any part of the o-rings, split rings, bypass valve or control valve.

Plug into an electrical outlet. Note:  All electrical connections must be connected according to local codes. (Be certain the 

outlet is uninterrupted.)

Install grounding strap on metal pipes.

 (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. When the LERCV1 control valve is manufactured as a softener, the control 

valve can be ordered to perform downflow or upflow regeneration. When the LERCV1 control valve is set up as a filter, the 

control valve can be set to perform downflow regeneration or simply backwash. The control valve can be set to regenerate 

on demand (consumption of a predetermined amount of water) and/or as a time clock (passage of a particular number of 

days). The control valve can be set so that a softener can meet the Water Quality Association (WQA) Standard S100 or 

NSF/ANSI Standard 44 efficiency rating.

It is not recommended to change control valves from downflow to upflow brining or vice versa in the field. The 

valve bodies for downflow and upflow are unique to the regeneration type and should not be interchanged. A 

mismatch of valve body and regeneration piston will result in hard water bypass during service.

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.
