Sentinel™ Water Softeners 1” & 1.25” Control Valve with Fully Adjustable Cycles Operation and Instruction Manual for OEM/Dealer Introduction This manual is about a control valve to be used on water softeners or water filters. The manual is designed to aid water treatment equipment manufacturers in the selection of the various control valve options. Information in this manual is different than what is needed for installation and servicing of a particular water treatment system. This manual is not intended to be used as a manual fora complete water softener or filter. Certain parts of the manual will serve as aids to manufacturers in the writing and layout of the manuals for installers and service personnel. The following general warnings and the specifications in Table 1 must appear in the OEM’s System Manual. 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. 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. Avoid any type of lubricants, including silicone, on the clear lip seals. 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, press and hold NEXT and REGEN buttons for 3 seconds or unplug power source jack from the printed circuit board (black wire) and plug back in. 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.

FAQs

What is the purpose of this manual for Sentinel water softeners?

The manual supports water treatment equipment manufacturers in selecting control valve options for softeners or filters. It is not intended to replace a complete installation or servicing manual for a specific water treatment system.

What lubricants should not be used during maintenance?

Avoid Vaseline, oils, other hydrocarbon lubricants, and spray silicone anywhere. Silicone lubricant may be used on black o-rings, but it is not necessary, and lubricants including silicone should be avoided on clear lip seals.

How do you reset the valve electronics after drive assembly or piston maintenance?

Press and hold the NEXT and REGEN buttons for 3 seconds, or unplug the power source jack from the printed circuit board (black wire) and plug it back in. The display should flash all wording, then flash the software version, and reset the valve to the service position.
