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 up to +40 °C / 64.4 °F to 104 °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 +25 °C / 77 °F to which the specified technical data relate. For other ambi-
ent conditions, deviations from the indicated data are possible.
• Permissible ambient humidity: 70 % r.H. max., non-condensing.
• 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 160 mm / 6.30 in, sides 100 mm / 3.94 in. Spacing
above the chamber of at least 100 mm / 3.94 in must also be accounted for.
• 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 160 mm / 6.30 in, sides 100 mm / 3.94 in.
• Spacing above the chamber of at least 100 mm / 3.9 in must also be accounted for.
Two devices up to size 115 can be stacked on top of each other. For this purpose place rubber pads under
all feet of the upper chamber to prevent the device from slipping.
NOTICE
Risk of damages by sliding or tilting of the upper chamber.
Damage to the chambers.
When stacking, place rubber pads under all feet of the upper chamber.
Stack only chambers of the same size.
Chambers sizes 260 and 720 must NOT be stacked.
NOTICE
Danger by stacking.
Damage to the chambers.
∅ Do NOT place chambers sizes 260 or 720 on top of each other.
Other requirements
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.
Do not conduct the power cable above the exhaust duct.
