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 tech-
nical data, chap. 23.4). The chambers are designed for setting up inside a building (indoor use).
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.
Ambient conditions
• Permissible ambient temperature range during operation: +18 °C / 64.4 °F to +32 °C / 89.6 °F. At ele-
vated 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 re-
lates. Deviations from the indicated data are possible for other ambient conditions.
With each degree of ambient temperature > +25 °C / 77°F, the refrigeration power de-
creases 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 hu-
midity may lead to condensation on the chamber.
• Installation height: max. 2000 m / 6562 ft. above sea level.
Minimum distances
• 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 / 3.9 in, sides 160 mm / 6.29 in.
• Spacing above the chamber of at least 100 mm / 3.9 in must also be accounted for.
