Heat emission of electrical devices connected inside the chamber may modify the tempera-
ture and humidity range.
The chambers are equipped with a door heating system to prevent condensation in the door area.
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 for several days:
• 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 (Manual mode).
• Only then, shut down the chamber at the main power switch (1) and close
the water
supply tap.
Having turned off the chamber by the main power switch (1), always close the water supply
tap.
If you operate the chamber at high humidity and then immediately turn off the chamber, the internal
wastewater collector may overflow due to the condensate. This may lead to the emergence of water at the
chamber.
NOTICE
Danger of water emerging at the chamber due to the overflow of the internal
wastewater tank by condensate.
Damage to the surroundings of the chamber.
∅ Following high humidity operation, do NOT directly turn off the chamber.
 Pump off the condensate before shut-down:
• Set the humidity to 0 % r.h. The humidity system must be activated
. Operate the
chamber for at least 2 hours.
• Only then, shut down the chamber at the main power switch (1) and close
the water
supply tap.
