Heat emission of electrical devices connected inside the chamber may modify the tempera-
ture and humidity range.
If the set points for temperature or humidity are outside the optimum range, condensation can arise in the
door area. Operating the chamber at humidity values > 70 % r.h. for a long period may lead to corrosion on
the housing.
NOTICE
Danger of corrosion on the housing due to condensation by excess humidity.
Damage to the chamber.

Dry the chamber completely before shut-down:
•
Set the humidity to 0 % r.h. The humidity system must be activated.
•
Set the temperature set point to 60 °C /
140 °F
for approx. 2 hours.
• Only then, shut down the chamber at the main power switch (1) and empty the fresh-
water can.
Having turned off the chamber by the main power switch (1), empty the freshwater can.
If you operate the chamber at high humidity and then immediately turn off the chamber, the condensate
collection pan may overflow due to the condensate. This may lead to the emergence of water at the cham-
ber.
Regularly check the filling level of the condensate collection pan.
19.1 Function of the humidifying and dehumidifying system
Humidifying system
The humidifying and dehumidifying system is located in the humidity generation module. In a cylindrical
container with a volume of approx. 0,07 liters an electrical resistance heating evaporates water. The water
content is kept close to the boiling point, and thus steam can be immediately generated 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 into the condensate collection pan.
Freshwater
Freshwater is supplied by manually filling a freshwater can. The freshwater can be placed on top of the
chamber or in an optionally available magnetic support.
In order to ensure accurate humidifying, observe the following points with regard to
the freshwater supply:
•
Water type: deionized (demineralized) water
•
To ensure humidification during 24 hours even at high humidity set-points, we recommend
filling the freshwater can at the end of each day.
•
Water intake temperature NOT below +5 °C /
41 °F
and not exceeding 40 °C /
104 °F
