5.8 Performance when opening the door
When you open the door the fan starts running with minimum speed (30 %).
After 60 seconds from opening the door, heating, refrigeration, and fan turn off. The compressor contin-
ues operating during 5 minutes without cooling function.
After closing the door, heating, refrigeration, and fan turn on again.

Warming chambers may release odors in the first few days after commissioning. This is not a quality de-
fect. To reduce odors quickly we recommend heating up the chamber to its nominal temperature for one
day and in a well-ventilated location.
For control reasons the refrigeration machine starts with a delay time. The refrigeration ma-
chine also turns off with a 5 minutes delay. This explains why the compressor may remain
operating also during positive temperature jumps.
