After extensive operation at humidity levels > 70% r.h., condensation from excessive humidity can lead to
corrosion during storage. In this case the chamber must first be dried.
NOTICE
Danger of corrosion on the housing due to condensation by excess humidity after
operating at humidity values > 70 % r.h. for a long period.
Damage to the chamber.
Let the chamber dry for several days before shut-down:
• Set the humidity to 0 % r.h. To enable dehumidification, the humidifying and dehu-
midifying system must be activated (deactivated “Humidity off” function chap. 8).
• 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.
When after storage in a cold location you transfer the chamber to its warmer installation site, condensation
may form. Before start-up, wait at least one hour until the chamber has attained ambient temperature and
is completely dry.
In case of a prolonged temporal decommissioning: Leave the chamber door open or remove the access
port plugs.
3.4 Location of installation and ambient conditions
Set up the chamber on a flat, even surface, and in a well-ventilated, dry location and align it using a spirit
level. The site of installation must be capable of supporting the chamber’s weight (see technical data,
chap.25.4). The chambers are designed for setting up inside a building (indoor use).
NOTICE
Danger of overheating due to lack of ventilation.
Damage to the chamber.
∅ Do NOT install the chamber in unventilated recesses.
Ensure sufficient ventilation for dispersal of the heat.
Observe the prescribed minimum distances when installing the chamber.
Do not install or operate the chamber in potentially explosive areas.
DANGER
Danger of explosion due to combustible dusts or explosive mixtures in the vicinity
of the chamber.
Serious injury or death from burns and / or explosion pressure.
∅ Do NOT operate the chamber in potentially explosive areas.
KEEP explosive dust or air-solvent mixtures AWAY from the vicinity of the chamber.
There is a condensate collection pan under the chamber. Water could be spilled when emptying the pan.
