6. Water connection
Risk of scalding!
Very hot water to be found in and around the
steam humidifier during and after operation
.
Have all installation work done by expert staff
in order to avoid scalding hazards due to
improper water guidance.
Risk of electrical shock!
Hazardous electrical voltage!
Before starting installation work ensure that
the unit is not yet connected to the power
supply.
General Rules
•
Obey local water utility regulations
•
Verify that necessary safety mea-
sures have been taken – in compli-
ance with either German Technical
and Scientific Association for Gas
and Water (DVGW) guidelines (DIN
EN1717) or local regulations – that
eliminate backflow of polluted water
into drinking water treatment facili-
ties. This may require the installation
of a system separator of the CA type
(minimum measure, allowable only
when free discharge into the drai-
nage system is given). 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.
•
Supply water must not exceed
40 °C
•
Allowable range of water pressure:
1 to 10 bar (100 x 10
3
to 100 x 10
4
Pa)
• For connection to the water supply
pipe, make use of a water hose
• Blow-down water must drain freely
•
Min. conductivity of feedwater:
3µS/cm
6.1 Water supply
Foreign material in water supply pipe may
cause premature wear of the solenoid
valve.
Flush the water supply pipe before making
connection to the solenoid valve. This is of
particular importance in case of a newly
installed pipe.
» Install a shut-off valve (SV) in the
supply line.
» Install a water filter (WF) if required
due to bad water quality.
Shut-off valve (SV) and water filter (WF) are
not included in the delivery.
For connection to the water supply line, the
water hose (56) with cap nuts (1) on both
ends supplied with the unit may be used.
