Touching live electrical parts can cause an electric shock.
▶ Before working on electrical parts, disconnect all phases of the
power supply (fuse/circuit breaker) and lock the isolator switch to
prevent unintentional reconnection.
If a fault occurs during operation, a fault code appears in the display

If a fault is present for more than 10 minutes:
▶ Briefly interrupt the power supply and switch the indoor unit back on.
If a fault persists:
