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 ele-
vated ambient temperature values, fluctuations in temperature can occur.
The ambient temperature should not be substantially higher than the indicated ambient tem-
perature of +25 °C / 77 °F to which the specified technical data relate. For other ambient condi-
tions, deviations from the indicated data are possible.
• Permissible ambient humidity: 70 % r.h. max., non-condensing.
When operating the chamber at temperature set-points below ambient temperature, high ambient humidi-
ty may lead to condensation on the chamber.
• Installation height: max. 2000 m / 6562 ft. above sea level.
Minimum distances:
• Distance between each chamber when placing several chambers of the same size side by side: 250
mm / 9.84 in
• Lateral wall distance: 200 mm / 7.87 in
• Wall distance rear: 300 mm / 11.81 in
• Chambers with optional water cooling (without options compressed air dryer and / or voltage and fre-
quency changer): Wall distance rear 100 mm / 3.94 in.
• Chambers with optional compressed air dryer: Wall distance rear approx. 1 m / 3.28 ft so that it is pos-
sible to read the status display of the compressed air dryer on the chamber rear.
• Chambers with voltage and frequency changer: rear wall distance of the alternating climate chamber
approx. 1 m / 3.28 ft to set up the voltage and frequency changer
• To completely separate the chamber from the power supply, you must disconnect the power plug. In-
stall the chamber in a way that the power plug is easily accessible and can be easily pulled in case of
danger.
• Spacing above the chamber: 100 mm / 3.94 in
CAUTION
Danger by stacking.
Damage to the chambers.
∅ Do NOT place the chambers on top of each other.
With an increased amount of dust in the ambient air, clean the condenser fan several times a year. We
recommend checking the fan grid (behind the left maintenance access flap) every week. In case of visible
dirt accumulation, disconnect the chamber and clean the fan grid by suction.
Avoid any conductive dust in the ambiance according to the chamber layout complying with pollution de-
gree 2 (IEC 61010-1).
