Beware of condensation 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

13、 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.
