Do not use a load cylinder. Protect the heat pump components, including the insulation and structural elements. Do not overheat the pipes as brazed com ponents may cause damage. Contact between the refrigerant fluid and a flame may result in emissions of toxic gases.

France: Pursuant to Article L. 113-3 of the French Consumer Code, the in stallation of equipment must be done by a certified operator whenever the refrigerant load is in excess of two kilograms or when a refrigerant connec tion is necessary (the case with split systems, even when fitted with a quick coupling device).

All work on the refrigeration circuit must be done by a qualified professio nal, according to prevailing codes of practice and safety in the profession (recovery of the refrigerant, brazing under nitrogen). All brazing work must be done by qualified welders.

Do not touch the refrigeration connection pipes with your bare hands while the heat pump is running. Danger of burn or frost injury.

In the event of a refrigerant leakage:

1. Switch off the appliance.

2. Open the windows.

3. Do not use a naked flame, do not smoke, do not operate electrical contacts.

4. Avoid contact with the refrigerant. Danger of frost injuries.

Locate the probable leak and seal it immediately. Use only original parts to replace a defective refrigeration component.

Use only dehydrated nitrogen for detecting leaks or for pressurised tests.

Do not allow the refrigerant fluid to escape into the atmosphere.

1.5 Domestic water safety

In accordance with safety rules, a safety valve calibrated to 0.7 MPa (7 bar) is mounted on the tank's domestic cold water inlet.

A pressure reducer (not provided) is required when the supply pressure exceeds 80% of the safety valve or safety unit calibration and must be lo cated upstream of the appliance.

There must be no cut-off devices between the safety valve or unit and the domestic hot water tank.

The hydraulic installation must be capable of handling a minimum flow rate at all times.

Heating water and domestic water must not come into contact with each other. Domestic water must not circulate through the exchanger.

Limit temperature at the draw-off point: the maximum domestic hot water temperature at the draw-off point is subject to special regulations in the various countries in which the appliance is sold in order to protect the user. These special regulations be observed when installing the appliance.

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

1 Safety instructions and recommendations

7682850 - v02 - 09012018 MIV-4S 7

In order to limit the risk of being scalded, a thermostatic mixing valve must be installed on the domestic hot water flow pipes.

1.6 Hydraulic safety

When making the hydraulic connection, it is imperative that the standards and corresponding local directives be respected.

If radiators are connected directly to the heating circuit: install a differential valve between the indoor module and the heating circuit.

Keep a heating circuit without thermostatic valve and or without solenoid valve in order to avoid having all valves closed at the same time.

Fit drainage valves between the indoor module and the heating circuit.

Do not add any chemical products to the heating water without first con sulting a water treatment specialist. For example: antifreeze, water soften ers, products to increase or reduce the pH value, chemical additives and/or inhibitors. These may cause faults in the heat pump and damage the heat exchanger.

1.7

Recommendations for operation

The frost protection function does not work if the heat pump is switched off.

If the home is unoccupied for a long period and there is a risk of frost, drain the indoor module and the heating system.

Keep the heat pump accessible at all times.

Never remove or cover the labels and data plates affixed to appliances. Labels and data plates must be legible throughout the entire lifetime of the appliance.

Immediately replace damaged or illegible instructions and warning stick ers.

Give preference to the OFF or frost protection mode rather than switching off the system to leave the following functions running:

Anti blocking of pumps Frost Protection

Regularly check the presence of water and pressure in the heating sys tem.

Do not touch radiators for long periods. Depending on the heat pump set tings, the temperature of the radiators may exceed 60°C.

Do not drain the installation, except in cases of absolute necessity. E.g.: several months' absence with the risk of temperatures in the building fall ing below freezing.

1.8

Specific instructions for service, maintenance and breakdowns

Maintenance work must be carried out by a qualified professional.

Only a qualified professional is authorised to set, correct or replace the safety devices.

Before any work, switch off the mains electricity to the heat pump, the in door unit and the hydraulic or electrical back-up if connected.

Wait for approx. 20-30 seconds for the outdoor unit capacitors to be dis charged, and check that the lights on the outdoor unit PCBs have gone out.

Before working on the refrigeration circuit, switch off the appliance and wait a few minutes. Certain items of equipment such as the compressor and the pipes can reach temperatures in excess of 100 °C and high pres sures, which may cause serious injuries.

Locate and correct the cause of power cut before resetting the safety ther mostat.

1 Safety instructions and recommendations

8 MIV-4S 7682850 - v02 - 09012018

Only genuine spare parts may be used.

Removal and disposal of the heat pump must be carried out by a qualified professional in accordance with prevailing local and national regulations.

Do not allow the refrigerant fluid to escape into the atmosphere.

After maintenance or repair work, check the entire heating system to en sure that there are no leaks.

Remove the casing only to perform maintenance and repair work. Put the casing back in place after maintenance and repair work.
