2. Safety instructions and recommendations AWHP MIT-IN iSystem

2 Safety instructions and

recommendations

2.1 Safety instructions

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.

2.2 Recommendations

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.

WARNING

4 Any intervention on the appliance and heating

equipment must be carried out by a qualified engineer.

4 For a proper operating of the boiler, follow carefully

the instructions.

24/09/2012 - 300027606-001-01

AWHP MIT-IN iSystem 2. Safety instructions and recommendations

Keep this document close to the place where the boiler is installed.

CAUTION

4 Use tools and pipe components especially designed

for use with R410A refrigerant.

4 Install the appliance on a solid, stable structure able

to bear its weight.

4 Use phosphorous-deoxidised copper for pipes

without welds and copper alloy to connect the pipes carrying the refrigerant.

4 Use only R410A gas to fill the pipes with refrigerant. 4 Do not install the appliance in a place where it may

be exposed to steam, sulphuric gas or combustion, an atmosphere with a high salt content, or which may be covered by snow.

4 Ensure correct earthing. 4 Store the refrigeration connection pipes away from

dust and humidity (danger of damage to the compressor) and cover both ends until the expansion process is complete.

4 Do not use a load cylinder.

CAUTION

4 Activate the main switch at least 12 hours before the

appliance starts to function. Using the appliance just after it is switched on may seriously damage the internal parts.

4 When switching off the appliance, wait for at least 5

minutes of post-operation before deactivating the main switch. Danger of breakdown or water leak.

CAUTION

In order to limit the risk of being scalded, the installation of a thermostatic mixing valve on the domestic hot water flow piping is compulsory.

Before carrying out any maintenance work requiring the shutdown of the inside module, also cut the power supply to the outside module to prevent any errors in communication.

3. Technical description AWHP MIT-IN iSystem

3 Technical description

3.1 General description

The AWHP MIT-IN iSystem heat pump is composed of two elements:

4 The outside unit handles energy production in hot or cold mode. 4 The inside module handles thermal exchange between the R410A

fluid and the hydraulic circuit.

The two units are connected by means of refrigeration and electrical connections.

The system offers the following advantages:

4 The heating circuit is housed in the insulated volume within the

home. There is no danger of the pipes freezing.

4 Thanks to the DC inverter system, the heat pump modulates its

output to adapt to the needs of the home.

4 The control panel uses the outside temperature sensor to adjust

the temperature of the heating circuit according to the outside temperature.

3.3.1. General

The outside module produces heat or cold (in reversible versions) and transmits it to the heating circuit via the refrigerant in the plate exchanger. The outside module is capable of operating at outside temperatures down to -20°C (-15°C in the case of a 6MR or 8MR heat pump).

The DIEMATIC iSystem control panel is used to programme and regulate the heat pump according to the outside temperature.

By activating the pumps and, where necessary, the mixer valve, the regulator handles the regulation of the heating.

Connection of a CDR4 simplified remote control or a CDI4 interactive remote control enables the auto-adaptivity of the gradient and the parallel offset of the heating curve.

The antifreeze function on the installation is active whatever the operating mode. It is triggered as soon as the outdoor temperature reaches the limiting value preset to +3°C.

The installation of a buffer tank is not necessary if the volume of water in the circuit is higher than or equal to 3 litres/kW: Therefore, for a heat pump with an output of less than 11 kW, with a water volume of less than 33 litres, the installation of a buffer tank is necessary.

4.4.1. Location of the appliance

This data plate is affixed to the inside side panel of the appliance in the factory.

When installation has been completed, affix the data plate provided in the instructions bag to the casing of the appliance in a position where it can be seen.

Ensure that the outside module is optimally positioned in relation to neighbours as it is a source of noise.

CAUTION

4 There must be no obstacles hindering the free

circulation of air around the outdoor module (intake and output).

4 No not locate the outside unit close to where people

sleep.

4 Do not locate the unit opposite a wall with windows. 4 Avoid placing it close to a terrace, etc..

Choose a location away from prevailing winds.

AWHP MIT-IN iSystem 4. Installation

In some cases, additional precautions are necessary owing to the fact, for example, of too short a distance between you and your neighbours. When installing a noise reduction screen, respect the following recommendations:

4 Locate the noise reduction screen as close as possible to the noise

source whilst allowing for the free circulation of air in the exchanger on the outside unit and maintenance work.

Place the outside unit on a base (concrete base frame, sill, concrete blocks, etc.) with no rigid connection with the building served in order to prevent any transmission of vibrations. Ensure

sufficient above ground elevation (100 to 150 mm) to keep it above water. For regions where heavy snowfalls occur, raise this above ground protection by at least 200 mm compared with the average depth of the covering of snow.

CAUTION

If the outside temperatures become negative, take the necessary precautions to prevent the risk of freezing in the evacuation pipes. Prevent any risk of the condensates freezing in an area through which they flow.

The heating cord keeps the condensates from freezing: See EH113 leaflet.

Distances to be observed

WARNING

To ensure that the heat pump functions correctly, respect the minimum and maximum connection lengths between the heat pump and the indoor module.
