4.2 Connection to a suction plant (optional)
When directly connecting a suction plant the spatial temperature exactitude, the heating-up and the
recovering times and the maximum temperature will be negatively influenced. So no suction plant should
be directly connected to the exhaust duct.
Active suction from the chamber must only be performed together with extraneous air.
Perforate the connecting piece to the suction device or place an exhaust funnel at some
distance to the exhaust duct.
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.
5. Start up
5.1 Turning on the chamber
Warming chambers may release odors in the first few days after commissioning. This is not a
quality defect. To reduce odors quickly we recommend heating up the chamber to its nominal
temperature for one day and in a well-ventilated location.
1.
Insert the power plug into a suitable socket (chap. 4.1).
2.
Turn on chambers at the main power switch (10)
The green “Standby“ LED illuminates.
3.
Press
until the display lights up.
The controller is now in normal display (actual value display).
If the chamber is operating (time functions “Continuous operation”, or “Timer
operation” with the set time just running down chap. 6.3), the
actual
temperature value
(example: 22 °C) is displayed
If the chamber is in time function “Timer operation” with no time programmed or the set time run-off (chap.
6.3), the chamber is inactive (no heating). The display alternately shows the
actual temperature value
(example: 22 °C) and “
tOff
”:
Adjust the temperature safety device following any changes of the set-point (chap. 7).
5.2 Heating operation display
The heating is active as soon as the red heating control light in the bottom
right corner of the display slowly begins to flash depending on the heat
requirement (example: 70 °C):
