EQUIPMENT INSTALLATION

General Warnings And Safety Information

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 connec-
tions 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 back-
wash 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.

General
• Observe all warnings that appear in this manual.
• Keep the media tank in the upright position. Do not turn on side, upside down, or
drop. Turning the tank upside down will cause media to enter the valve.
• Operating ambient temperature is between 34°F (1°C) and 120°F (49°C).
• Operating water temperature is between 34°F (1°F) and 100°F (38°C).
• Working water pressure range is 20 to 120 psi (1.38 to 8.27 bar). In Canada the
acceptable working water pressure range is 20 to 100 psi (1.38 to 6.89 bar).
• Use only regenerant salts designed for water softening. Do not use ice melting, block,
or rock salts.
• Follow state and local codes for water testing. Do not use water that is micro biologi-
cally unsafe or of unknown quality.
• When filling media tank, do not open water valve completely. Fill tank slowly to
prevent media from exiting the tank.
• When installing the water connection (bypass or manifold) connect to the plumbing
system first. Allow heated parts to cool and cemented parts to set before installing any
plastic parts. Do not get primer or solvent on O-rings, nuts, or the valve.
