Beware of condensation
When water vapor comes into contact with the surface of
cold material, water drops are produced.
If condensation occurs, correct operation may not be possi-
ble, or the unit may not function correctly.
This is not a malfunction, however, the unit should be dried.
(To do this, turn the POWER switch ON and leave the unit
as it is for several hours.)
Be especially careful in the following conditions :
When the unit is brought from a cold place to a warm place,
and there is a large temperature difference.
When a heater starts operating.
When the unit is brought from an air-conditioned place to a
place of high temperature with high humidity.
When there is a large difference between the internal tem-
perature of the unit and the ambient temperature, or in con-
ditions where condensation occurs easily.
