Children shall not play with the appliance. Cleaning and user maintenance shall not be made by children without supervision.

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.

AWHP-2 MIT-IN-2 iSystem 1. Safety instructions

10/06/2015 - 7616372-001-05

WARNING

Take precautions when dealing with domestic hot water.Depending on the settings of the heat pump, the domestic hot water temperature may exceed 65°C.

CAUTION

Use only original spare parts.

WARNING

Only qualified professionals are authorised to work on the appliance and the installation.

Insulate the pipes to reduce heat losses to a minimum.

WARNING

The installation must comply in all matters to the standards and rules which govern the work and interventions in individual and collective homes, and other constructions.

CAUTION

The heating water and the water in the domestic circuit must never come into contact with each other.

Electrical connection

4 Allowance must be made for a means of disconnection

in the fixed pipes in accordance with the regulations on installations.

4 Always have the power cord replaced by a qualified

installer if it is damaged.

WARNING

Depending on the settings of the appliance:

4 The temperature of the radiators may reach

80°C.

4 Do not touch the refrigeration connection

pipes with your bare hands while the appliance is running. Danger of burns or frost injury.

CAUTION

Do not neglect to service the appliance. Contact a qualified professional or take out a maintenance contract for the annual servicing of the appliance.

1.2 Recommendations

WARNING

Only qualified professionals are authorised to work on the appliance and the installation.

4 Regularly check that the water pressure in the

installation is between 1,5 and 2 bar.

4 Ensure that the appliance is accessible at all times for

maintenance purposes.

4 Avoid draining the installation. 4 Use only original spare parts. 4 Never remove or cover labels and rating plates affixed

1.3 Specific safety instructions

1.3.1. Safety data sheet: R-410A refrigerant

Product identification

4 Refrigerant name: R-410A

Hazard identification

4 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 and eye injuries.

4 Product classification: This product is not classified as

a "hazardous preparation" according to European Union regulations.

CAUTION

If refrigerant is mixed with air, it may lead to pressure surges in the refrigeration pipes and cause an explosion and other hazards.

Composition / Information on the ingredients

4 Chemical nature: Mixture of R-32 and R-125. 4 Ingredients that may lead to hazardous situations:

Substance name

Concentration CAS number CE number Classification Global warming potential

1,1-Difluorométhane R-32 50% 75-10-5 200-839-4 F+ ; R12 650

Pentafluoroethane R-125 50% 354-33-6 206-557-8

First aid

4 If inhaled: Evacuate the subject from the contaminated

area and take him into the open air. If feeling unwell: Call a doctor.

1. Safety instructions

AWHP-2 MIT-IN-2 iSystem

10/06/2015 - 7616372-001-05

4 In the event of contact with the skin: Treat frost

injuries as burns. Rinse in abundant water, do not remove clothing (risk of adhesion to the skin). If skin burns appear, call a doctor immediately.

4 In the event of contact with the eyes: Rinse

immediately in water, holding the eyelids well apart (at least 15 minutes). Consult an ophthalmologist immediately.

Fire prevention measures

4 Appropriate extinguishing agents:

- Carbon dioxide (CO2)

- Powders

- Foam

- Water spray.

4 Inappropriate extinguishing agents: None to our

knowledge. In the event of fire nearby, use the appropriate extinguishing agents.

4 Specific hazards:

- Toxic and corrosive vapours may be released by the effect of the heat.

- Elevated pressure: in the presence of air, an inflammable mixture may form under certain temperature and pressure conditions.

4 Special intervention methods: Cool the volumes

exposed to heat with water spray.

4 Protection of the firemen:

- Full facepiece self-contained breathing apparatus

- Complete body protection.

In the event of accidental spillage

4 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 (Risk of

asphyxia).
