larly switched on and off by the electricity provider.
Note
This manual can also be found on our internet site.
1.2 Recommendations
Caution
Install the hydraulic module and the boiler for the hy
brid system in a location protected from freezing.
Caution
If the home is unoccupied for a long period and there
is a risk of frost, drain the hybrid system.
Note
Keep the hybrid system accessible at all times.
1 Safety
7611444 - v02 - 11122015 7
Note
Never remove or cover labels and data plates affixed
to the appliances. Labels and data plates must be
legible throughout the entire lifetime of the appliance.
Immediately replace damaged or illegible instructions
and warning stickers.
Note
Remove the casing only to perform maintenance and
repair work. Put the casing back in place after mainte
nance and repair work.
Warning
Only qualified persons are authorised to assemble, in
stall and maintain the installation.
Warning
The hybrid heat pump (heat pump and boiler) must be
disassembled and disposed of by a qualified installer
in accordance with local and national regulations.
Warning
If the mains lead is damaged, it must be replaced by
the original manufacturer, the manufacturer's dealer
or another suitably skilled person to prevent hazard
ous situations from arising.
Caution
The hybrid system should be in Summer or Frost Pro
tection mode rather than switched off to guarantee the
following functions:
Anti blocking of pumps
Frost Protection
Note
Regularly check the presence of water and pressure
in the heating installation.
Note
Keep this document close to the place where the ap
pliance is installed.
Caution
Do not make any modifications to the hybrid system
without the written consent of the manufacturer.
Caution
Do not neglect to service the hybrid system. Contact a
qualified professional or take out a maintenance con
tract for the annual servicing of the hybrid system.

1.3 Specific safety instructions
Warning
Refrigerant fluid and pipes:
Use only R410A refrigerant fluid to fill the installa
tion.
Use tools and pipe components especially designed
for use with R410A refrigerant fluid.
Use copper pipes deoxidised with phosphorus to
carry the refrigerant fluid.
Store the refrigerant connection pipes away from
dust and humidity (risk of damage to the compres
sor).
Do not use a load cylinder.
Protect the heat pump components, including the in
sulation and structural elements. Do not overheat
the pipes as brazed components may cause dam
age.
Contact between the refrigerant fluid and a flame
may result in emissions of toxic gases.
1.3.1 Refrigerant fluid R410A
Hazard identification
Effects harmful to health:
The vapours are heavier than air and may lead to asphyxia
owing to reduced oxygen levels.
Liquefied gas: contact with the liquid may cause serious
frost burn and eye injuries.
Product classification: this product is not classified as a
"hazardous preparation" according to European Union reg
ulations.
If the R410A refrigerant is mixed with air, it may cause pres
sure surges in the refrigeration pipes and lead to an explo
sion and other hazards.
Composition of / Information on the ingredients
Chemical nature: R-410A is composed of Difluoromethane
R32 and Pentafluoroethane R125
Tab.1 Composition of R-410A fluid

7611444 - v02 - 11122015 19
4 Description of the product
4.1 General description
The hybrid heat pump comprises:
an indoor module for the production of heating circuit water
a reversible outdoor unit for the production of energy in heating mode
and in cooling mode.
The indoor module comprises:
a hydraulic module, which groups together the functions for the heat
pump's indoor module
a wall-mounted condensing gas boiler, installed on the front of the hy
draulic module
The indoor module and the outdoor unit are connected by means of refrig
erant and electrical connections.
The system offers the following advantages:
An extremely compact solution which can be easily integrated into the
most confined areas of any residence.
The heating circuit is housed in the insulated volume within the home.
Thanks to the DC inverter system, the hybrid heat pump modulates its
output to adapt to the needs of the residence.
The control system uses the outside sensor to adjust the temperature of
the heating circuit according to the outside temperature.
The outer casing of the hydraulic module is made of painted steel sheet
ing.
4.2 Operating principle
Heat pumps in the Alezio G hybrid range extract heat from the air and re
turn it to the heating circuit via the refrigerant. The efficiency of a heat
pump is expressed in the form of a coefficient of performance (COP), de
fined as the ratio between the heat provided and the power consumed.
The heat pump comprises an evaporator, a compressor, a condenser and
an expansion valve. The indoor module includes the condenser. The other
components (evaporator, compressor and expansion valve) are located in
the outdoor unit.
1. The refrigerant fluid in this circuit is converted from the liquid state to
the gaseous state in the evaporator, making it possible to recover heat
from the air.
2. The compressor increases the fluid pressure, which thus increases
the temperature.
3. In the condenser, the fluid transfers the heat to the heating circuit
while converting to the liquid state.
4. The refrigerant passes through the thermostatic expansion valve and
returns to the initial state at low pressure and low temperature before
returning to the evaporator.
