If feeling unwell: call a doctor.
In the event of contact with the skin:
Treat frost injuries like burns. Rinse with copious amounts of tepid
water, do not remove clothing (risk of adhesion to the skin).
If skin burns appear, call a doctor immediately.
In the event of contact with the eyes:
Rinse immediately with water, holding the eyelids well apart (for at
least 15 minutes).
Consult an ophthalmologist immediately.
Fire prevention meas­
ures
In the event of acci­
dental spillage
Appropriate extinguishing agents: All extinguishing agents can be
used.
Inappropriate extinguishing agents: none to our knowledge. In the
event of fire nearby, use the appropriate extinguishing agents.
Specific hazards:
Rise in pressure: in the presence of air, an inflammable mixture
may form under certain temperature and pressure conditions.
Toxic and corrosive vapours may be released by the effect of the
heat.
Special intervention methods: cool the volumes exposed to heat with
water spray.
Protection of the firemen:
Full self-contained breathing apparatus.
Complete body protection.
Individual precautions:
Avoid contact with the skin and eyes.
Do not intervene without appropriate protective equipment.
Do not inhale the vapours.
Evacuate the hazardous area.
Stop the leakage.
Eradicate all sources of ignition.
Ventilate the spillage area mechanically.
Cleaning / decontamination: allow any residual product to evaporate.
In the event of contact with the eyes: Rinse immediately with water,
holding the eyelids well apart (for at least 15 minutes). Consult an oph­
thalmologist immediately.

4.1
Description of the product
General description
The ALEZIO EVOLUTION heat pump comprises:
An outdoor unit for energy production in heating mode only when it is
combined with an uninsulated indoor module.
A reversible outdoor unit for energy production in heating or cooling
mode when it is combined with an insulated indoor module.
An indoor module with a control panel to handle the heat exchange be­
tween the R410A fluid and the hydraulic circuit.
Both units are connected by means of refrigeration and electrical connec­
tions.
The system offers the following advantages:
The heating circuit is housed in the insulated volume within the home.
Thanks to the DC inverter system, the heat pump modulates its output
to adapt to the needs of the home.
The control panel uses the outside sensor to adjust the temperature of
the heating circuit according to the outside temperature.
4.2
Operating principle
4.2.1
Circulating pump
Note
The benchmark for the most efficient circulating pumps is EEI ≤
0.20.
4.2.2
Hybrid operating mode
Note
The hybrid operating mode is only available for appliances with
hydraulic back-up.
The appliance offers a choice between several hybrid operating modes.
The modes available offer either optimised energy consumption according
to energy cost, or optimised energy consumption according to primary en­
ergy consumption. Both hybrid operating modes are available via the pa­
.
rameter
In optimised primary energy consumption mode, the control system
chooses the generator that consumes the least primary energy.
In optimised energy cost mode, the control system chooses the cheap­
est generator according to the coefficient of performance of the heat
pump and according to energy cost.

Maintenance
7.1
General instructions
Maintenance operations are important for the following reasons:
To guarantee optimum performance.
To extend the life of the equipment.
To provide an installation which offers the customer optimum comfort
over time.
Caution
An annual service of the heat pump is mandatory.
7.2
Maintenance instructions
1. Check the hydraulic pressure in the installation.
Note
If the water pressure is lower than 1 bar, more water should be
added. If necessary, top up the water level in the heating system
(recommended hydraulic pressure between 1.5 and 2.0 bar, or be­
tween 0.15 and 0.2 MPa)..
Fig.23
2. Carry out a visual check for any water leaks.
3. Open and close the radiator valves several times a year.
This helps to prevent the valves from seizing up.
4. Clean the outside of the heat pump using a damp cloth and a mild
detergent.
Beware of water leaks
Caution
Only qualified professionals are permitted to clean the inside of
the heat pump.
AD-0001507-A
7.3
Topping up the installation with water
If necessary, top up the water level in the heating system (recommended
hydraulic pressure between 1.5 and 2 bar, or between 0.15 and 0.2 MPa).
1.
2.
3.
4.
5.
Open the valves on all radiators connected to the heating system.
Set the room thermostat to as low a temperature as possible.
Put the heat pump in shut-down/frost protection mode.
Open the fill valve.
Close the fill valve when the pressure gauge shows a pressure of
1.5 bar (0.15 MPa).
6. Put the heat pump in heating mode.
7. When the pump has stopped, vent again and top up the water pres­
sure.
Note
Filling and venting the installation twice a year should be sufficient
to obtain an adequate hydraulic pressure. If it is often necessary
to top up the installation with water, contact your installer.
7.4
Venting the heating system
It is essential that you vent any air in the domestic hot water tank, the
pipes and the taps to prevent the annoying noises likely to be produced
during heating or when drawing off water.

Energy savings
Energy-saving advice:
Do not block ventilation outlets.
Do not cover the radiators. Do not hang curtains in front of the radiators.
Install reflective panels behind the radiators to prevent heat losses.
Insulate the pipes in rooms that are not heated (cellars and lofts).
Close the radiators in rooms not in use.
Do not run hot (or cold) water pointlessly.
Install an energy-saving shower head, which can save up to 40 % ener­
gy.
Take showers rather than baths. A bath consumes twice as much water
and energy.
10.2
Room thermostat and settings
Various models of room thermostat are available. The type of thermostat
used and the parameter selected impact total energy consumption.
A modulating regulator, which may be combined with thermostatic
valves, is eco-friendly in terms of energy and offers an excellent level of
comfort. This combination allows you to set the temperature separately
for each room. However, do not install thermostatic radiator valves in the
room in which the room thermostat is located.
Complete opening and closing of the thermostatic radiator valves cau­
ses undesirable variations in temperature. Therefore, these must be
opened/closed progressively.
Set the room thermostat to a temperature of approximately 20°C to re­
duce heating costs and energy consumption.
Lower the thermostat setting to approximately 16°C at night or when you
are not at home. This reduces heating costs and energy consumption.
Lower the thermostat setting well before airing the rooms.
Set the water temperature to a lower level in summer than in winter (e.g.
60°C and 80°C respectively) when an ON/OFF thermostat
is used.
When clock thermostats and programmable thermostats are to be set,
do not forget to take any holidays and days when no one is at home into
account.
