CAUTION
The exhaust duct will become hot during operation.
Danger of burning.
∅ Do NOT touch the exhaust duct during operation.
5. Start up
Having connected the electrical supply (chap. 4.1), turn on the chamber by the main power switch (1).
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.
5.1 Air change
Opening the air flap in the exhaust duct serves to adjust the air change.
Without connecting a suction plant:
• If the air flap is open and the fan is operating, fresh air comes in via aeration gaps.
• If the air flap is completely open, the spatial temperature accuracy can be negatively influenced.
5.2 Settings at the RD3 program controller
After turning the chamber on with the main power switch (1) the controller is in Normal Display / fixed
value operation mode.
Depending on the temperature value entered before LED (3a) is lit if the heating is active, or no LED if the
actual temperature is equal to or above the set-point.
In Display 1 of the controller the actual temperature value is displayed.
• With inactive week program timer:
In Display 2 of the controller the actual date and time are displayed. Example:
15.05.06 13:52
• With active week program timer:
In Display 2 of the controller the actual date and time and the states of the week program timer
channels are displayed. Examples:
15.05.06 13:52 - -
15.05.06 13:52 - �
