3-3 Electric connections:
CAUTION: before connecting the appliance, make sure that the supply power line is disconnected from the network.
Characteristics of the general power supply:

mode of neutral TT and TN.S; the circuit of heat pump must be connected to an earthing circuit
Connections:

The electric installation must be carried out by a professional qualified (like an electrician) according to the rules and standards in
force in the country of installation.

The power supply of the heat pump must come preferably from an exclusive circuit and having the bodies of lawful protection.

Controller must be installed or indoor wall and the place is easy for use.
Electric protection of which must lay out the heat pump:

circuit breaker curves D or standard fuse of protection Am, gauged with 16A

differential protection of 30 mA
In the event of connection to an electrical plug by the user:
- - The heat pump is being provided with an electric cable, it is possible to connect it with a plug.
- The plug must be checked in conformity with the power of the appliance by a qualified technician.
- The plug must be safe from the rain, of easy access to be cleaned and one will have to regularly check the good condition of this plug.
BEFORE THE STARTUP OF HEAT PUMP, IT IS SIGNIFICANT TO
INCLUDE/UNDERSTAND THE OPERATING AND THE SETTINGS OF WHICH YOU WILL
TAKE NOTE IN THE FOLLOWING PARAGRAPHS
3-4 Running of reversible heat pump :
By using the free energy contained in the ambient air, the heat pump enables to heat the water of the water in a
very economic way.
Your heat pump is a heat machine that can transfer the heat from a low temperature place (ambient air) to a
higher temperature place.
Running in heating mode :
The heat of the air is absorbed by the cold, liquid refrigerant, through the evaporator (radiator with wings), in
which it’s vaporized; then the compressor increases the pressure and the temperature, and sends it into
the condenser
(exchanger) where it loses its heat by transmitting it to the water and it comes back in the liquid state; it loses its pressure and
cools again into the pressure reducer before returning to the evaporator for a new cycle.
Running in cooling mode or defrosting mode :
4 way valve enables to reverse the cycle of the refrigerant ; the liquid fluid is vaporized into the exchanger (that
becomes the evaporator) by taking the heat of the water of the water, passes into the compressor which heats it then into the
radiator (which becomes the condenser) where it comes back at the liquid state.
Note: Single water heater without cooling water mode; Single water chiller without heating water mode and defrosting mode.
