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

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.

4 Description of the product

4.1 General description

The MIV-4 heat pump comprises:

an indoor module, including a domestic hot water tank and a control panel. A reversible outdoor unit for energy production in heating or cooling mode.

Back-up is possible:

Either via an immersion heater that can be set to 3, 6 or 9 kW (versions with electrical back-up) Or via a gas or oil boiler already in use on the installation (versions with hydraulic back-up).

The indoor module and the outdoor unit are connected by means of refrig erant and electrical connections.

The indoor module handles heating and domestic hot water production.

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. The steel domestic hot water tank is fitted with a magnesium anode and lined with food quality standard enamel vitrified at 850°C, which protects the tank from corrosion. The heat exchanger in the domestic hot water tank is a coil welded in side the tank, made of smooth piping. Its external surface, which comes into contact with drinking water, is enamelled. The domestic hot water tank is insulated by Chlorofluorocarbon-free pol yurethane foam, which helps to keep heat losses to a minimum.

4.2 Operating principle

The heat pumps in the MIV-4 range extract the heat found in the air to re store it to the heating and/or domestic hot water circuit via the refrigerant fluid. The efficiency of a heat pump is expressed in the form of a coeffi cient of performance (COP), defined as the ratio between the heat provi ded 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.

11.1 Energy savings

Tips on saving energy:

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). Turn off the radiators in rooms not being used. Do not run hot (or cold) water pointlessly. Install a water-saving shower head to save up to 40% energy. Take showers rather than baths. A bath consumes twice as much water and energy.
