Water Installation
Warning:
For installation, note the following:
•
Have all work performed by a professional.
•
Disconnect power supply prior to installation. Obey regula-
tions of local public utilities.
•
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 - to eliminate backflow of pol-
luted water into drinking water treatment facilities. This can
mean installing a system separator and a free discharge in
the drainage system. Within the humidifier, two double
check valves (58) are located in the water supply lines.
They prevent - in accordance with DIN EN 61770 - the
backflow of water.
•
The water supply temperature may not exceed 40 °C/
104°F. Flushed-out water must be able to drain freely.
•
The water supply line must have a minimum diameter of
DN 12 (3/8").
•
If (chemical) additives are present in the humidification
water, health risks and/or impaired unit operation cannot
be ruled out. Use of additives is not advised unless specif-
ically recommended by the unit manufacturer.
•
When employing demineralized water or purified conden-
sate, do not use copper or brass in the supply or drain
lines of the HeaterLine unit. These materials can be cor-
roded by demineralized water or purified condensate.
Instead, use stainless steel or temperature-resistant plas-
tic pipes.
•
Water installation pressure: 1bar min., 10bar max./
14.5 psi min., 145 psi max.
•
For water installation please use the water connecting
hose that is delivered with the unit.
6.1
Water Quality
The HeaterLine Type steam humidifier is designed for use with:
•
tap water with a total hardness of max. 18.8°e
•
demineralized water (min. conductivity 3µS/cm)
•
fully cleaned condensate (min.conductivity 3µS/cm)
•
partially or fully softened water
Boiling normal tap water always produces lime. Lime deposits
on the surface of the heater elements may reduce their lifetime.
We recommend to use a water treatment device in order to pre-
vent scaling. In case of any questions regarding water treatment
devices please contact HygroMatik.
