General Warnings And Safety Information
The 268 and 255 water conditioner’s control valve conforms to NSF/ANSI 44
and 61 for materials and structural integrity only. Generic systems were tested
and certified by WQA as verified by the performance data sheet.
Electrical
There are no user-serviceable parts in the AC adapter, motor, or controller. In
the event of a failure, these should be replaced.
• All electrical connections must be completed according to local codes.
• Use only the power AC adapter that is supplied.
• The power outlet must be grounded.
• To disconnect power, unplug the AC adapter from its power source.
Mechanical
• Do not use petroleum based lubricants such as vaseline, oils, or
hydrocarbon based lubricants. Use only 100% silicone lubricants.
• 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 pliers or
pipe wrenches.
• All plumbing must be completed according to local codes.
• Soldering near the drain line should be done before connecting the drain
line to the valve. Excessive heat will cause interior damage to the valve.
• Observe drain line requirements.
• Do not use lead-based solder for sweat solder connections.
• The drain line must be a minimum of 1/2-inch diameter. Use
3/4-inch pipe if the backwash flow rate is greater than 7 GPM
(26.5 Lpm) or the pipe length is greater than 20 feet (6 m).
• Do not support the weight of the system on the control valve fittings,
plumbing, or the bypass.
• It is not recommended to use sealants on the threads. Use Teflon* tape
on the threads of the 1-inch NPT elbow, the drain line connections, and
other NPT threads.
