System Installation
Pre-Installation Considerations
• A minimum of 25psi of water pressure is required for regeneration
valve to operate effectively.
• 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.
• 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.
• The softener should be located close to a drain.
• Always provide for the installation of a bypass valve. A system
bypass is included with this system.
• The full weight of the plumbing system must be supported by
pipe hangers or other means.
• Do not install the system where it would block access to the water
heater, main water shutoff, water meter, or electrical panels.
• Install the system in a place where water damage is least likely
to occur if a leak develops.
• If applicable, use di-electric unions where dissimilar metals
are present.
The main control valve and all plumbing connections have
right-hand threads. Turn clockwise to install.
NOTICE
If O-ring lubricant is required, only use a silicone based
compound formulated for potable water O-ring applica-
tions. Watts recommends Ordering Code #68102757 Silicone
Lubricant. 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.
NOTICE
WARNING
!
Do not exceed water pressure of 125psi (8.6 bar). Do
not exceed 110°F (43°C). Do not subject unit to freezing
conditions.
