4.3 Connection to an exhaust/ventilation system (optional)
Active suction from the chamber must only be effected together with external air. Therefore, the chamber’s
exhaust air duct shall not be immediately connected to an active exhaust system.
When connecting to an active exhaust system, proceed as follows:
• Perforate the connecting piece between the exhaust air duct and the exhaust system.
Or
• Use an exhaust air funnel placed in a distance of 3-5 cm / 1 to 2 in from the exhaust air duct. The
funnel’s opening must be at least twice as large as the diameter of the exhaust air duct.
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 duct on the chamber rear will become hot during operation
CAUTION
Danger of burning by touching hot chamber parts during operation.
Burns.
∅ Do NOT touch the exhaust duct during operation.
4.4 Inserting the racks
Observe the correct orientation of the racks:
Standard rack: The lateral brackets must be above the rack surface when inserting the rack.
Optional heavy load rack: The lateral brackets must be below the rack surface when inserting the rack.
