water spray.

Protection of the firemen:

Full self-contained breathing apparatus.

Complete body protection.

In the event of acci

dental spillage

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.

Handling Technical measures: ventilation

Precautions to be taken:

No smoking.

Prevent the build-up of electrostatic charges.

Work in a well ventilated place.

Personal protection

Respiratory protection:

If ventilation is insufficient: AX type cartridge mask.

In confined spaces: self-contained breathing apparatus.

Hand protection: protective gloves in leather or nitrile rubber.

Eye protection: safety glasses with side protection.

Skin protection: clothing made principally of cotton

Industrial hygiene: do not drink, eat or smoke at the place of work.

Considerations on dis

posal

Important

Disposal must be done in compliance with prevailing lo

cal and national regulations.

Product waste: consult the manufacturer or the supplier for informa

tion on recovery or recycling.

Soiled packaging: reuse or recycle after decontamination. Destroy in

authorised installations.

4 Description of the product

4.1 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.
