WS1TT Drawings and Service Manual
Introduction
This manual is about a control valve to be used on water softeners or water
fi
lters. 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 for a
complete water softener or
fi
lter.
General Warnings
The control valve,
fi
ttings 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 Te
fl
on tape on the threaded inlet, outlet and drain
fi
ttings. Te
fl
on 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
fl
ash all wording, then
fl
ash 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
fl
ow rates in excess of 7 gpm (26.5 lpm) or length in excess of 20

drain line.
Solder joints near the drain must be done prior to connecting the drain line
fl
ow control
fi
tting. Leave at least 6
”
between the drain
line control
fi
tting and solder joints when soldering pipes that are connected on the drain line control
fi
tting. Failure to do this could
cause interior damage to the drain line
fl
ow control
fi
tting.
When assembling the installation
fi
tting package (inlet and outlet), connect the
fi
tting to the plumbing system
fi
rst 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.
