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 measures
have been taken – in compliance with
either German Technical and Scientific
Association for Gas and Water
(DVGW) guidelines (DIN EN1717) or
local regulations – that eliminate back-
flow of polluted water into drinking
water treatment facilities. This may
require the installation of a system sep-
arator of the CA type (minimum mea-
sure, allowable only when free
discharge into the drainage 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
(104°F)
•
Allowable range of water pressure: 1 to
10 bar /14.5 to 145 psi (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
The following applies to electrode steam
humidifiers:
•
Use feed water without chemical addi-
tives and with a conductivity between
200 and 800 µS/cm only. Beyond con-
ductivity levels of 800µS/cm up to a
maximum of
1250µS/cm and below
conductivity levels of 200µS/cm to a
minimum of
125µS/cm, special adjust-
ments are required. In this case please
contact your specialist dealer.
•
As an option for installation by the cus-
tomer, the DVGW-conform
HyFlow
system separator or a after market sys-
tem separator of the BA/CA type are
available from HygroMatik.
The following applies to heater steam
humidifiers:
•
min. conductivity of feedwater: 3µS/cm
•
from a water hardness of 15° German
hardness, a preceding water softening
is recommended
•
operation with fully softened water (0°
German hardness) is possible
