6. Water Installation
Warning:
When installing the water installation, note the follow-
ing:
•
Have all work performed by a professional.
•
Disconnect power supply before installation.
•
Obey local public utility
regulations
•
Verify that necessary safety measures have been taken
– in compliance with either German Technical and Sci-
entific Association for Gas and Water (DVGW) guide-
lines (DIN EN1717) or local regulations – to eliminate
backflow of polluted water into drinking water treatment
facilities. This can mean installing a backflow preventer
and a free discharge into the drainage system. Within
the humidifier, a double check valve (58) is located in
the water supply line. It prevents - in accordance with
DIN EN 61770 - the backflow of water. Alternatively, a
DVGW-conform HyFlow may be used that makes fur-
ther safety measures obsolete.
•
Use feed water without chemical additives and with a
conductivity between 200 and 800 µS/cm only. Above
conductivity levels of 800µS/cm to a maximum of
1250µS/cm and below conductivity levels of 200µS/cm
to a minimum of
125µS/cm, special adjustments are
required. In this case please contact HygroMatik.
•
The water supply temperature may not
exceed 40° C.
•
Water installation pressure: 1 - 10 bar (100 x 10
3
to 100
x 10
4
pascal).
•
Blow-down water must be able to drain.
•
For water installation please use the water connecting
hose that is delivered with the unit.
6.1 Operation with Softened Water
Warning:
Unless special measures are taken, feeding softened
water into the HygroMatik steam humidifier is dangerous. It can
cause
•
unacceptably high conductivity
•
the formation of salt bridges between the electrodes
and the electrode leads on the inner surface of the top
part of the steam cylinder
•
foaming in the steam cylinder
Salt bridges cau se e lectrical arcs. Th ese are in dicated b y the
presence of black grooves in the top part of the cylinder. The top
part must be replaced to prevent further damage to the cylinder
material, as well as short circuits which trip main circuit breakers.
Foam comes into contact with the maximum wa ter level sensor
electrode and triggers a signal indicating the cylinder is f illed to
capacity, even though this is false and the nominal current has
not yet been reached.
Note:
Please contact HygroMatik if you wish to operate the unit
