2 Safety instructions and
recommendations
2.1 Safety instructions
DANGER
If smoke is released or in case of refrigerant leak:
1. Do not use a naked flame, do not smoke, do not
operate electrical contacts or switches ( doorbell,
light, motor, lift, etc..).
Contact between refrigerant and a flame may result
in emissions of toxic gases.
2. Open the windows.
3. Trace possible leaks and seal them immediately.
WARNING
Before any work, switch off the mains supply to the
appliance.
WARNING
Do not touch the refrigeration connection pipes with your
bare hands while the appliance is running. Danger of
burns or frost injury.
2.2 Recommendations
WARNING
4Any intervention on the appliance and heating
equipment must be carried out by a qualified
engineer.
4For a proper operating of the boiler, follow carefully
the instructions.
AWHP-2 MIT-IN-2 iSystem 2. Safety instructions and recommendations
25/06/2014 - 7616371-001-04 9

Keep this document close to the place where the boiler is
installed.
CAUTION
4Use tools and pipe components especially designed
for use with R410A refrigerant.
4Install the appliance on a solid, stable structure able
to bear its weight.
4Use phosphorous-deoxidised copper for pipes
without welds and copper alloy to connect the pipes
carrying the refrigerant.
4Use only R410A gas to fill the pipes with refrigerant.
4Do not install the appliance in a place where it may
be exposed to steam, sulphuric gas or combustion,
an atmosphere with a high salt content, or which may
be covered by snow.
4Ensure correct earthing.
4Store the refrigeration connection pipes away from
dust and humidity (danger of damage to the
compressor) and cover both ends until the expansion
process is complete.
4Do not use a load cylinder.
CAUTION
4Activate the main switch at least 12 hours before the
appliance starts to function. Using the appliance just
after it is switched on may seriously damage the
internal parts.
4When switching off the appliance, wait for at least 5
minutes of post-operation before deactivating the
main switch. Danger of breakdown or water leak.
CAUTION
In order to limit the risk of being scalded, the installation of
a thermostatic mixing valve on the domestic hot water flow
piping is compulsory.
Before carrying out any maintenance work requiring the
shutdown of the inside module, also cut the power supply
to the outside module to prevent any errors in
communication.

3 Technical description
3.1 General description
The AWHP-2 MIT-IN-2 iSystem heat pump is composed of two
elements:
4The outside unit handles energy production in hot or cold mode.
4The inside module handles thermal exchange between the R410A
fluid and the hydraulic circuit.
The two units are connected by means of refrigeration and electrical
connections.
The system offers the following advantages:
4The heating circuit is housed in the insulated volume within the
home. There is no danger of the pipes freezing.
4Thanks to the DC inverter system, the heat pump modulates its
output to adapt to the needs of the home.
4The control panel uses the outside temperature sensor to adjust
the temperature of the heating circuit according to the outside
temperature.

3.3 Operating principle
3.3.1. General
The outside module produces heat or cold (in reversible versions) and
transmits it to the heating circuit via the refrigerant in the plate
exchanger.
The outside module is capable of operating at outside temperatures
down to -20°C (-15°C in the case of a 4 kW or 6 kW heat pump).
The DIEMATIC iSystem control panel is used to programme and
regulate the heat pump according to the outside temperature.
By activating the pumps and, where necessary, the mixer valve, the
regulator handles the regulation of the heating.
Connection of a CDR4 simplified remote control or a CDI4 interactive
remote control enables the auto-adaptivity of the gradient and the
parallel offset of the heating curve.
The antifreeze function on the installation is active whatever the
operating mode. It is triggered as soon as the outdoor temperature
reaches the limiting value preset to +3°C.
The installation of a buffer tank is not necessary if the volume of water
in the circuit is higher than or equal to 3 litres/kW: Therefore, for a
heat pump with an output of less than 11 kW, with a water volume of
less than 33 litres, the installation of a buffer tank is necessary.
