Remarks: the above are not only the maximum frequency limitations of the complete appliance which are
affected by the environment, but also the maximum ability limitation of the system. When the starting ability is
not the maximum, its maximum frequency limitation is calculated by the following equations:
The frequency limitation which is affected by the temperature and under the condition of actual ability
˙
the
actural running system ability*the maximum frequency which is limited by the temperature and under the
condition of maximum ability/the maximum designing ability of the system

The outdoor fan control (exchange fan)
When the fan is changed among every airflow speed (including stop blowing), in order to avoid the airflow
speed from skipping frequently, it must be kept under each mode for over 30 seconds, and then it can be
changed to another mode (when refrigerating, the time is changed to 15 seconds).
