Water Supply
The water supply is to be carried out according to the figure found in this chapter and the
applicable local and national regulations for water installations. The indicated connection
specifications must be observed.
The installation of the shut-off valve, pressure reducing valve and a water filter should be
made as close as possible to the unit.
Water Quality
For the water supply of the Nortec MH, use exclusively untreated drinking water, Reverse
Osmosis Water, fully demineralised water or partly softened water.
The use of additives such as corrosion inhibitors, disinfectants, etc., is not allowed, since
these additives may endanger health and affect proper operation.
If the Nortec MH shall be operated with softened water, please contact your Nortec supplier.
The connection material must be pressure-proof and certified for use in drinking water supply
systems.
Important: Before connecting the water line to the unit, the line must be flushed thoroughly.
The thread at the humidifier connection is made of plastic. To avoid overtightening, the union nut
of the water pipe must be tightened by hand only.
Water Drain
The water drain is to be carried out according to the figure found in this chapter and the
applicable local and national regulations for water installations. The indicated connection
specifications must be observed.
Make sure the drain line is installed with a constant down-slope to the siphon of the building.
Make sure the drain pipe is correctly fixed and easily accessible for inspections and cleaning
purposes.
The minimum inside diameter of the drain pipe is 1.25" (31.75 mm). It must be maintained
throughout the entire length.
Fully demineralized water is aggressive, therefore when operating the NORTEC MH Series with
fully demineralized water, only us plastic or stainless steel installation materials.
