The water supply is to be carried out according to the figure above
and the applicable local regulations for water installation.
The indicated connection specifications must be observed.
– Admissible supply water temperature 33.8 to 77.0ºF (1 to 25ºC).
– Admissible mains pressure 30 to 80 (hammer-free system).
Notes on water quality:
For the water supply of the Nortec RS, use exclusively untreated
drinking water, water from RO system or de-ionized water.
– The use of additives such as corrosion inhibitors, disinfectants,
etc. is not allowed, since these additives may endanger health
and affect proper operation.
– Conductivity should be between 1 and 1500
μS/cm. Note that
conductivity less than 1 μS/cm is
very aggressive water (this is
equivalent to a resistivity of 1 M
Ω
or greater). It is recommended
to blend such water with other less-treated water to ensure the
supply is not overly aggressive.
– Hardness should be between 0 and 12 grains/gallon.
– Silica content should be between 0 and 12 ppm.
– pH should be between 6.5 and 7.5.
– Chloride content should be between 0 and 50 ppm.
– The connection material must be pressure-proof and certified
for use with the particular supply (drinking water, RO, or DI water).
– Important! Before connecting the water line, the line must be
well flushed out.
The water drain is to be carried out according to the figure found in
Section 5.6.1 of the RS Series Installation Manual, 2582419 and
the applicable local regulations for water installations. The
indicated connection specifications must be observed.
– Make sure that the drain pipe is correctly fixed and easily
accessible for inspections and cleaning purposes.
– The draining temperature is maximum 140ºF (60ºC). Use
temperature-resistant materials only!
– Lead drain line down to the funnel with a constant downslope
(min. 1.2°).
Note: On units with two steam tanks, each drain line must be led
into a separate funnel with trap.
– Attach drain line in such a way, that it cannot slip out of the
funnel or bottom out in the funnel.
– The open end of the drain line must not touch the funnel (min.
air gap 0.79" (2 cm)).
– We recommend to install the funnel with an lateral off-set of 8"
(20 cm) to the side of the unit, to prevent damage to humidifier
due to rising steam.
