When water vapor comes into contact with the surface of cold
material, water drops are produced.

or the unit may not function correctly.

(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 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 tempera-
ture of the unit and the ambient temperature, or in conditions
where condensation occurs easily.
