DANGER
Electrical shock!
The heat pump contains current-carrying components and the heat
pump capacitor must be discharged once the power supply has been
disconnected.
▶ Isolate the system from the supply.
▶ Wait at least five minutes before carrying out electrical work.
DANGER
Poisonous gas leakage!
The refrigerant circuit contains substances that can be transformed into
poisonous gas if they come into contact with air or open fire. Even in
small concentrations, these gases can cause respiratory failure.
▶ Leave the area immediately if the refrigerant circuit is leaking and
ventilate thoroughly.
NOTICE
