To avoid possible harm to persons or damage to products, read and follow these safety notes.
3.1 General Safety Notes for preventing electric shocks and
other hazards to health
WARNING
Danger to life from electric shock!
The devices are operated with 230 V or 400 V alternating current. Improper installation can present
a danger to life from electric shock as well as a danger of re occurring due to overheating.
► Electrical installation work must be undertaken by a trained electrician.
► Service and maintenance work must only be carried out by an accredited electrician or an
authorised dealer.
► Keep children and people unfamiliar with the equipment away from any installation work.
► Adherence to national and local standards and provisions is to be observed when
carrying out any installation work.
► Ensure that all cables and power connections, including those already in place, are of
adequate dimensions for the electrical power of the heat pump.
► Only use licensed power cords for connecting to a power source. No modied cables or
extension cables are to be used for connecting to the power source.
► The heat pumps must be duly earthed. Earthing is not to be undertaken via gas or water
pipes, lightning conductors or earthing for a telephone system.
► Adherence is to be paid to the respective national electrical wiring regulations and safety
arrangements with regard to residual current. Panasonic recommends using a residual
current circuit breaker (RCCB).
CAUTION
Danger of frostbite from the skin coming into contact with the refrigerant
Direct contact of the skin with the refrigerant can cause frostbite.
► Work on the refrigeration circuit and in connection with the refrigerant must be carried out
by a trained technician or an authorised trader holding a refrigerant handling certicate.
► Wear gloves when handling refrigerants (e.g. when emptying or lling the refrigeration
circuit).
► Observe the Safety Notes in force for the respective refrigerant (R32, R410A or R407C).
Danger of re and explosion caused by inammable gases
A danger of re or explosion arises when any leakages of inammable gases occur at the
installation site of the heat pump.
► Do not install heat pumps at sites where inammable gases can escape.
Danger due to toxic gases if the refrigerant comes into contact with re
Toxic gases can be created when escaped refrigerants come into contact with re.
For this reason, if refrigerants escape during installation or operation:
► Extinguish any sources of re (if present).
► Thoroughly ventilate the room in which the heat pump is installed.
