inflammable mixture may form under certain

temperature and pressure conditions.

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 accidental spillage

Individual precautions:

Avoid contact with the skin and eyes.

Do not intervene without appropriate protective

equipment.

4 Description of the product

4.1 General description

The AWHP-2 MIT-IN-2 iSystem heat pump is composed of two elements:

The outdoor module handles energy production in heating or cooling

mode.

The indoor module is equipped with a specific control system which is

used to adjust the temperature of the heating water to the needs of the

home.

Both units are connected by means of refrigeration (R410A fluid) and

electrical connections.

The system offers the following advantages:

The heating circuit is housed in the insulated volume within the home.

There is no danger of the pipes freezing.

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

to adapt to the needs of the home.
