Proper Installation
This water softening system must be properly installed and located in accordance with the
Installation Instructions before it is used or the warranty will be void.
Do not
install or store where it will be
exposed to temperatures below freezing or
exposed to any type of weather. Water
freezing in the system will break it. Do not
attempt to treat water over 100°F.
Do not
install in direct sunlight. Exces-
sive sun or heat may cause distortion or
other damage to non-metallic parts.
Maximum allowable inlet water pressure is
125 psi. If daytime pressure is over 80 psi,
night time pressure may exceed the maxi-
mum. Use a pressure reducing valve to
reduce the pressure.
Softener resins may degrade in the pres-
ence of chlorine or chloramines above 2
ppm. If there is chlorine or chloramines in
excess of this amount, it can reduce the
life of the resin. In these conditions, a car-
bon filter with a chlorine reducing media
may be considered. Contact US Water
Systems for Chlorine and Chloramine re-
moval equipment.
WARNING:
Discard all unused parts
and packaging material after installation.
Small parts remaining after the installation
could be a choke hazard.
