CAUTION
Condensation by excess humidity.
Danger of corrosion on the housing after operating at humidity values > 70 % r.H.
for a long period.
Dry the appliance completely before shut-down:
•
Set the humidity to 0 % r.H. and turn on humidity switch (3).
•
Set the temperature set point to 60 °C /
140 °F
for approx. 2 hours (Manual mode).
•
Only then, shut down the unit at the main power switch (2) and close the water sup-
ply tap.
Having turned off the unit by the main power switch (2), always close the water supply tap.
If you operate the unit at high humidity and then immediately turn off the unit, the internal wastewater
collector may overflow due to the condensate. This may lead to the emergence of water at the unit.
CAUTION
Overflow of the internal wastewater tank due to condensate.
Emergence of water at the unit.
∅
Following high humidity operation, do NOT directly turn off the unit.
Pump off the condensate before shut-down:
•
Set the humidity to 0 % r.H. and turn on humidity switch (4). Operate the unit for at
least 2 hours.
•
Only then, shut down the unit at the main power switch (3) and close the water sup-
ply tap.
12.1 Function of the humidifying and dehumidifying system
Humidifying system
The humidifying system is located in the humidity generation module. In a cylindrical container with a
volume of about 2 liters an electrical resistance heating evaporates water. The produced steam is main-
tained on a stable pressure level and is thus available in sufficient quantity for rapid humidity increases or
for compensation of humidity losses, e.g. by door openings. Condensation forming on the outer walls of
the useable volume is led through a water drain in the outer chamber into the waste water can which is
pumped off automatically to the wastewater pipe when required.
Freshwater
You can supply the unit with freshwater via a water pipe or by manually filling a freshwater can (option,
chap. 14.7). You can mount
the can on the rear of the unit or place it next to the unit.
In order to ensure accurate humidifying, observe the following points with regard to the
freshwater supply:
•
Supply pressure 1 to 10 bar when connecting to a water pipe
•
Water type: deionized (demineralized) water
•
To ensure humidification during 24 hours even at high humidity set-points with manual
water supply, we recommend filling the freshwater can (option) at the end of each day.
•
Water intake temperature NOT below +5 °C /
41 °F
and not exceeding 40 °C /
104 °F
.
