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 +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 unit.
•
Installation height: max. 2000 m /
6562 ft.
above sea level.
When placing several units of the same size side by side, maintain a minimum distance of 250 mm /
9.84
in
between each unit. Wall distances: rear 100 mm /
3.94 in
, sides 160 mm /
6.31 in
. Spacing above the
unit of at least 100 mm /
3.94 in
must also be maintained.
CAUTION
Danger by stacking.
Damage to the units.
∅
Do NOT place alternating climate chambers on top of each other.
To completely separate the unit from the power supply, you must disconnect the power plug. Install the
unit in a way that the power plug is easily accessible and can be easily pulled in case of danger.
With an increased amount of dust in the ambient air, clean the condenser fan (by suction or blowing) sev-
eral times a year.
Avoid any conductive dust in the ambiance according to the unit layout complying with pollution degree 2
(IEC 61010-1).
Do not install or operate the alternating climate chamber MK in potentially explosive areas.
DANGER
Explosion hazard.
Danger of death.
∅
Do NOT operate the unit in potentially explosive areas.
∅
KEEP explosive dust or air-solvent mixtures AWAY from the vicinity of the unit.
