With temperatures below +3 °C / 37.4 °F , water must be completely removed from the humidifying sys-
tem.
CAUTION
Storage below +3 °C / 37.4 °F with filled steam humidifying system.
Freezing in the steam generator.
Damage to the chamber.

Contact BINDER Service before any transportation below +3 °C / 37.4 °F .
Permissible ambient humidity: max. 70 % r.H., non-condensing
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 chamber completely before shut-down:
•
Set the humidity to 0 % r.H. To enable dehumidification, the humidifying and dehu-
midifying system must be activated (deactivated function “Humidity off”, 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
freshwater can.
When after storage in a cold location you transfer the chamber to its warmer installation site, condensa-
tion 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 constant climate 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.24.4). The chambers are designed for setting up inside a building (indoor use).
CAUTION
Danger of overheating.
Damage to the chamber.
∅
Do NOT set up chamber in non-ventilated recesses.

Ensure sufficient ventilation for dispersal of the heat.
•
Permissible ambient temperature range during operation : +18 °C / 64.4 °F to +32 °C / 89.6 °F . At
elevated ambient temperature values, fluctuations in temperature can occur.
The ambient temperature should not be substantially higher than the indicated ambient tem-
perature of +22 °C +/- 3 °C /
71.6 °F +/- 5.4 °F to which the specified technical data relate.
Deviations from the indicated data are possible for other ambient conditions.
With each degree of ambient temperature >25 °C / 77 °F , the refrigeration power decreases
by 1.5 K.
