5.5.2 Notes on water installation
Water supply
The water supply is to be carried out according to the gure found in chapter
5.5.1 and the applicable local regulations for water installations. The indicated
connection specications must be observed.
– The installation of the lter valve (accessory “Z261”, alternatively a
shutoff valve and a 5 µm water lter can be used) should be made as
close as possible to the steam humidier.
– Admissible mains pressure 1.0 to 10.0 bar (hammer-free system)
For mains pressures >10 bar, the connection must be made via a pres-
sure reducing valve (adjusted to 1.0 bar). For mains pressures <1.0 bar
please contact your Nordmann supplier.
– Notes on water quality:
– For the water supply of the Nordmann ES4, use exclusively untreated
drinking 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 Nordmann ES4 shall be operated with softened or partly sof-
tened water, please contact your Nordmann supplier.
– The connection material must be pressure-proof and certied for use
in drinking water systems.
– Important! Before connecting the water line, the line should be well
ushed out.
CAUTION!
The thread at the humidier 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 gure found in chapter
5.5.1 and the applicable local regulations for water installations. The indi-
cated connection specications must be observed.
– Make sure that the drain pipe is correctly xed and easily accessible for
inspections and cleaning purposes.
– The draining temperature is: 80…90 °C. Use temperature-resistant
installation materials only!
