Proper Installation
This RO 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 ex-
posed to temperatures below freezing or ex-
posed to any type of weather. Water freez-
ing in the system will break it. Do not attempt
to treat water over 100°F.
Do not install in direct sunlight. Excessive
sun or heat may cause distortion or other
damage to non - metallic parts.
Properly ground to conform with all govern-
ing codes and ordinances.
Use only lead - free solder and flux for all
sweat - solder connections, as required by
state and federal codes.
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 (PRV)
to reduce the pressure.
RO membranes will degrade in the presence
of chlorine or chloramines. In these condi-
tions, it is wise to consider purchasing a
backwashing carbon filter system with a
chlorine reducing media. Contact US Water
Systems for Chlorine and Chloramine remov-
al equipment.
WARNING: Discard all unused parts and
packaging material after installation. Small
parts remaining after the installation could be
a choke hazard.
