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
exactitude (uniformity), the heating-up and recovering times as well as the maximum tem-
perature of the chamber may be negatively affected.
CAUTION
The exhaust air outlet on the top of the chamber will become hot during operation.
Danger of burning.
∅ Do NOT touch the exhaust air outlet during operation.
4.3 Electrical connection
The chambers are supplied ready for connection and come with an IEC connector plug.

• The domestic socket must also provide a protective conductor. Make sure that the connection of the
protective conductor of the domestic installations to the chamber’s protective conductor meets the
latest technology. The protective conductors of the socket and plug must be compatible!
• Prior to connection and start-up, check the power supply voltage. Compare the values to the specified
data located on the chamber’s type plate (left-hand side of the chamber, chap. 1.4).
