When the heating operation is started,
the indoor fan does not start
immediately and the damper at the
bottom air outlet occasionally does not
open.

This is because the preheating device is working.
It will not start to drive the fan until the refrigerating
cycle warms up and warm air blows. Wait for a while.
The damper does not open either during preheating
or for one minute after preheating is finished.
