•
Before any work inside the appliance, you must cut the electricity supply to the appliance
as there is a risk of electric shock which may cause material damage, serious injury or even
death.
•
Incorrectly tightened terminals may cause the terminal box to heat up, which can invalidate
the warranty.
•
Only a qualified and experienced technician is authorised to carry out cabling work within the
appliance or to replace the power cord.
•
The installer must consult the electricity provided if necessary and ensure that the equipment
is connected correctly to an electricity network with impedance under 0.095 ohm.
•
The heat pump's electrical supply must be provided through a protection and circuit breaking device (not supplied)
complying with the standards and regulations in force in the country where it is installed,
•
The appliance is provided for connection to a general power supply with a TT or TN.S neutral regime.
•
Electrical protection: by circuit breaker (D curve, rating to be defined according to the table § ‘’5.2 I Technical
specifications’’), with a suitable dedicated differential protection device (circuit breaker or switch).
•
Additional protection may be required during installation to guarantee the II overvoltage category.
•
The power supply must correspond to the voltage indicated on the appliance's information plate.
•
The power cord must be insulated against any cutting or hot elements that may damage or crush it.
• The appliance must be connected to an earth socket.

The electrical connection lines must be fixed.
•
Use the gland to pass the power cord into the appliance.
•
Use the power cord (RO2V type) adapted for outdoor or buried use (or run the cable into a protection duct) with an
external diameter of between 9 and 18mm.
•
We recommend burying the cable at a depth of 50 cl (85 cm under a road or path) in an electrical duct (red ribbed).
•
If this buried cable meets another cable or pipe (gas, water, etc.), there must be more than 20 cm between them.
•
Connect the power supply cord to the spring-cage terminal block (see § «1.4.1 I Wiring on a spring-cage terminal
block») inside the appliance.
