Before Installation; Treatment Device Flow Scheme - A.O. Smith OPAL NW Series User Manual

BEFORE INSTALLATION
A. O.Smith water treatment system's operating water temperature is between minimum 5˚C (41˚F) and maximum
40˚C (104˚F). It has risk of freezing to operate the device below 5˚C as it carries risk of damage to filters when
operated at above 40˚C.
It is necessary to select a suitable location first for installation of A. O.Smith water treatment device. It must be
considered during selection that installation place should be close to cold water line of the RO device and to the
drainage and sufficient space should be left for working in case of malfunction and filter replacement.
Water treatment device is designed for water with specifications close to tap water, whose inlet conductivity
is max. 600 ppm and the turbidity is max 3 NTU. If raw water source and specifications are unknown, the raw
water should be sent for analysis before installation of the device in order to check the suitability.
"If the device is used beyond the limit values mentioned in technical specification part of the users' manual,
the requested quality will not be achieved for product water. Usage of such feed water will cause variation in
replacement periods of filters and membrane.
Inlet pressure is between 3 - 6 bar for water treatment devices without pump and between 1 - 6 bar for water
treatment devices with pump. The optimum working pressure is 3 bar. In case the inlet pressure is above 4
bar, it is recommended to install a pressure reducer to prevent more wastewa- ter discharge. Do not connect
the device to power socket before it is installed.Our company will not be liable for any problems caused by
nonobservance of the above warnings.
