Note Respect the minimum and maximum water inlet pres sure to ensure correct operation of the heat pump: re fer to the chapter Technical Specifications.

Caution Only genuine spare parts may be used.

Warning Only qualified professionals are authorised to work on the heat pump and the heating system.

Note Insulate the pipes to reduce heat losses to a mini mum.

Caution Ensure that the boiler is regularly serviced. Contact a qualified installer or arrange a maintenance contract for the servicing of the boiler.

Warning Do not touch the flue gas pipes. Depending on the boiler settings, the temperature of the flue gas pipes can rise to over 60°C.

Note Regularly check for the presence of water and pres sure in the heating installation.

1 Safety

Caution The system must satisfy each point in the rules in force in the country that govern works and interven tions in individual homes, blocks of flats or other build ings.

Note Heating water and domestic water must not come into contact with each other.

Electrical connection

Caution

The heat pump must always be connected to the protective earthing. Earthing must comply with the prevailing installation standards. Earth the appliance before making any electrical

connections. For the type and calibre of the protective equipment: refer to the chapter Recommended Cable Cross-sec tions in the Installation and Service Manual.

Caution A disconnection method must be allowed in the fixed pipes in accordance with the rules on installation in force in the country.

Caution If a power cord comes with the appliance and it turns out to be damaged, it must be replaced by the manu facturer, its after sales service or persons with similar qualifications in order to obviate any danger.

Caution In order to prevent any danger owing to the unexpec ted reset of the thermal circuit breaker, this appliance must not be powered through an external switch, such as a timer, or be connected to a circuit which is regu 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.

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

Name

Proportion Number CE Number CAS

Difluoromethane R32 50% 200–839–4 75-10-5

Pentafluoroethane R125 50% 206-557-8 354-33-6

The Global-Warming Potential of R410A gas is 2087.5.

Tab.2 Precautions for use

First aid If inhaled:

Evacuate the subject from the contaminated area and take him into the open air. 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

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.

In the event of acciden tal 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 ophthalmologist 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.
