Watts W110 Series - Manual (Page 4)

Safety Information
This water conditioner’s control valve conforms to UL/CE Standards .
Generic valves were tested and certified for compliance as verified by
the agency listing .
• Please review the entire Installation and Operation Manual
before installing the water conditioning system .
• As with all plumbing projects, it is recommended that a
trained professional water treatment dealer install the water
conditioning system . Please follow all local plumbing codes for
installing this water conditioning system .
• This system will not make microbiologically unsafe water safe .
Water that is unsafe must be treated separately from this
conditioner .
• This water conditioning system is to be used only for potable
water .
• Inspect the water conditioning system for carrier shortage or
shipping damage before beginning installation .
• Use only lead-free solder and flux, as required by federal and
state codes, when installing soldered copper plumbing .
• Use caution when installing soldered metal piping near the
water conditioning system . Heat can adversely affect the
plastic control valve and bypass valve .
• All plastic connections should be hand tightened . Teflon® tape
may be used on connections that do not use an O-ring seal .
Do not use pipe dope type sealants on the valve body . Do not
use pliers or pipe wrenches.
• Do not use petroleum-based lubricants such as Vaseline, oils
or hydrocarbon-based lubricants . Use only 100% silicone
lubricants .
• Use only the power transformer supplied with this water
conditioning system .
• All electrical connections must be completed according to local
codes .
• The power outlet must be grounded .
• Install an appropriate grounding strap across the inlet and
outlet piping of the water conditioning system to ensure that a
proper ground is maintained .
• To disconnect power, unplug the AC adapter from its power
source .
• Observe drain line requirements .
• Do not support the weight of the system on the control valve
fittings, plumbing, or the bypass .
• Do not allow this water conditioning system to freeze . Damage
from freezing will void this water conditioning system’s
warranty .
• Operating ambient temperature: 34° to 120°F (1° to 49°C) .
• Operating water temperature: 34° to 100°F (1° to 38°C) .
• Operating water pressure range : 25 to 120 psi (1 .38 to 8 .27
bar) .
• Observe all warnings that appear in this manual .
• Keep the media tank in the upright position . Do not turn upside
down or drop . Turning the tank upside down or laying the tank
on its side can cause media to enter the valve .
• Use only regenerants designed for water conditioning . Do not
use ice melting salt, block salt or rock salt .
During cold weather it is recommended that the installer warm
the valve to room temperature before operating .

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 ProSense 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 .
Pre-Installation Considerations
A. Water Pressure
A minimum of 25 pounds of water pressure is required for
regeneration valve to operate effectively .
B. Electrical Facilities
A continuous 115 volt, 60 Hertz current supply is required . Make
certain the current supply is always hot and cannot be turned off
with another switch .
C. Existing Plumbing
Condition of existing plumbing should be free from lime and iron
buildup . Piping that is built up heavily with lime and/or iron should
be replaced . If piping is clogged with iron, a separate iron filter unit
should be installed ahead of the water softener .
D. Location Of Softener And Drain
The softener should be located close to a drain .
E. Bypass Valves
Always provide for the installation of a bypass valve .
F. Valve to Tank Installation Instructions
1 . Spin the valve onto the tank, ensuring the threads are not cross-
threaded .
The main control valve and tank adaptor have right-hand threads, or
clockwise, to install
2 . Rotate the valve freely without using force until it comes to a stop
(this position is considered zero) .
3 . Rotate the valve clockwise from zero, between ¼ turn and ½
turn to fully tighten . No tools are needed . Hand tight is enough .
Overtightening may cause valve or tank damage .
If lubricant is required, a silicone compound is strongly
recommended . Dow Corning® Silicone Compound (available from
Watts), is recommended for best possible results . Dow Corning ® 7
Release Compound is used in the manufacture of this control valve .
The use of other types of lubricants may attack the control’s plastic
or rubber components . Petroleum-based lubricants can cause
swelling in rubber parts, including O-rings and seals .
