compressor crankcase heaters must remain switched on in these intervals).
Disconnect the unit from the power supply only in the event of prolonged
disuse (e.g. seasonal shutdowns). For temporary shutdown of the unit
refer to the guide lines given in paragraph 6.3.1.
If the unit fails to start:
do not change internal electrical connections on penalty of immedia-
te invalidation of the warranty.
Warning: The operating mode changeover should only be seasonal.
Frequent changeover from summer to winter operating mode and vice-
versa could cause damage to the compressors.
controller functions are activated.
The defrost timeout alarm is automatically cleared from the active alarms menus when a defrost cycle terminates
normally because the defrost end pressure has been reached. In any event, the alarms historical file will contain
a record of all defrost cycles that were terminated forcibly due to a timeout intervention.
Consecutive defrost cycles must be at least 30 minutes apart. If a forced defrost signal persists inform the Service
organisation.
