Notes on water installation
Water supply
The water supply is to be carried out according to the figure found in
local regulations for water installations. The indicated connection specifications must be observed.
– The installation of the
filter valve
(accessory "Z261", alternatively a shut-off valve and a 125 µm
water filter can be used) should be made as close as possible to the steam humidifier.
Note: on double units each unit must be connected separately via a filter valve (or shut-off valve and
water filter) to the water supply.
– Admissible water supply pressure:
–
1.0…10.0 bar
(units
without
drain water cooling)
–
2.0…10.0 bar
(units
with
drain water cooling)
Note: the supply water system must be hammer-free. For mains pressures >10 bar, the connection
must be made via a pressure reducing valve (adjusted to 2.0 bar). For mains pressures <1.0 bar
(units
without
drain water cooling) <2.0 bar (units
with
drain water cooling) please contact your
Nordmann supplier.
– Supply rate: 1 l/min per 15 kg/h steam capacity
–
Notes on water quality
:
– For the water supply of the Nordmann Omega Pro, 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.
– The connection material must be
pressure-proof
and
certified for use in drinking water systems
.
–
Important!
Before connecting the water line
, the line must be well flushed out
.
CAUTION!
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 figures found in
and the applicable
local regulations for water installations. The indicated connection specifications must be observed.
– Draining rate: approx. 2,5l/min per 15 kg/h steam capacity
– The draining temperature is: 80…90 °C (with optional drain water cooling <60°C). Use temperature-
resistant installation materials only!
– Make sure that the drain pipes, the funnel(s) and the siphon(s) are correctly fixed and easily acces-
sible for inspections and cleaning purposes.
– Always lead the supplied drain hose from the connector to the left down to the funnel (see
On double unit the drain hoses must be connected with hose clamps to a collector with constant
downslope (min. 15 %/8.5°). The drain of the collector must be led with constant downslope (min.
15 %/8.5°) into a funnel with trap (see
). The funnel must be positioned with a lateral off-set
to the left side of the unit, to prevent damage to humidifier due to rising steam.
