3.1 General Safety Notices 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
superheat.
► 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 regulations 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 modied 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 protection switch (FI protection switch).
CAUTION
Danger of frostbite from the skin coming into contact with the coolant
Direct contact of the skin with the coolant can cause frostbite.
► Work on the cooling circuit and in connection with the coolant must be carried out by a
trained technician or an authorised trader holding a coolant certicate.
► Wear gloves when handling coolants (e.g. when emptying or lling the cooling circuit).
► Observe the Safety Notices in force for the respective coolant (R410A or R407C).
Danger of re and explosion caused by inammable gases
A danger of re or explosion arises when any leakages of inammable gases occur at the
installation site of the heat pump.
► Do not install heat pumps at sites where inammable gases can escape.
