3.4 Location of installation and ambient conditions
Set up the chamber on a flat, even surface, free from vibration, 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. 20.4 and 20.5). The chambers are designed for setting up inside a building (indoor
use).
CAUTION
Danger of overheating.
Damage to the chamber.
∅ Do NOT set up chambers 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
temperature of +22 °C +/- 3 °C / 71.6 °F ± 5.4 °F to which the specified technical data relates.
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.
• Permissible ambient humidity: 70 % r.H. max., non-condensing.
When operating the chamber at temperature set-points below ambient temperature, high ambient
humidity may lead to condensation on the chamber.
• Installation height: max. 2000 m / 6562 ft. above sea level.
When placing several chambers of the same size side by side, maintain a minimum distance of 250 mm /
9.84 in between each chamber. Wall distances: rear 100 mm / 3.94 in, sides 160 mm / 6.29 in. Spacing
above the chamber of at least 100 mm / 3.94 in must also be maintained.
Two chambers of the same size can be piled on top of each other. For this purpose place rubber pads
under every foot of the upper chamber to prevent the device from slipping.
CAUTION
Sliding or tilting of the upper chamber.
Damage to the chambers.
 When stacking, place rubber pads under every foot of the upper chamber.
 Stack only chambers of the same size.
To completely separate the chamber from the power supply, you must disconnect the power plug. Install
the chamber in a way that the power plug is easily accessible and can be easily pulled in case of danger.
For the user there is no risk of temporary overvoltages in the sense of EN 61010-1:2010.
With an increased amount of dust in the ambient air, clean the condenser fan (by suction or blowing)
several times a year.
Avoid any conductive dust in the ambiance according to the chamber layout complying with pollution
degree 2 (IEC 61010-1).
