MITSUBISHI ELECTRIC SDP-Eco 1630 III - Manual (Page 43)

Chapter 4 Operation
When shutting down the machine by pressing the power ON/OFF key, the
dehumidifying heater will automatically run unless the main power is also shut
down. The dehumidifying heater attached below the plate setting section inhibits
condensation in the machine by heating plates when humidity is high and
temperature is low. The low temperature keeps the machine away from fire
danger.
During the final inspection, do not open the front door until the display
panel is turned off; otherwise the final inspection will stop in the middle
of the operation. Caution
