The chambers must NOT be stacked.
Danger by stacking.
Damage to the chambers.
∅ Do NOT place chambers 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.
For the user there is no risk of temporary overvoltages in the sense of EN 61010-1:2010.

4.1 Installing the racks
Insert 4 rack supports for each rack into the slots of the lateral inner chamber walls. They serve as a support
for the rack.

4.2 Connection to an exhaust/ventilation system (optional)
Active suction from the chamber must only be effected together with external air. Therefore, the exhaust
air outlet on the top of the chamber shall not be immediately connected to an active exhaust system.
When connecting to an active exhaust system, proceed as follows:
• Remove the black exhaust air flap.
• Perforate the connecting piece of the exhaust system or place an exhaust air funnel in a distance of 3-
5 cm / 1 to 2 in from the exhaust air outlet. The funnel’s opening must be at least twice as large as the
diameter of the exhaust air outlet.
If improperly connected to an active exhaust/ventilation system, the spatial temperature ex-
actitude (uniformity), the heating-up and recovering times as well as the maximum tempera-
ture of the chamber may be negatively affected.
The exhaust air outlet on the top of the chamber will become hot during operation.
CAUTION
Danger of burning by touching the exhaust air outlet parts during operation.
Burns.
∅ Do NOT touch the exhaust air outlet during operation.
