3 Description
3.1 General description
The ALEZIO heat pump comprises:
4An outside module for energy production in hot mode only when
it is combined with an uninsulated inside module.
4A reversible outside module for energy production in hot or cold
mode when it is combined with an insulated inside module
4An inside module with a control panel to handle the 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:
4The heating circuit is housed in the insulated volume within the
home. There is no danger of the pipes freezing.
4Thanks to the DC inverter system, the heat pump modulates its
output to adapt to the needs of the home.
4The control panel uses the outside temperature sensor to adjust
the temperature of the heating circuit according to the outside
temperature.

5 Checking and maintenance
5.1 General instructions
CAUTION
4An annual inspection is compulsory.
4We recommend taking out a maintenance contract.
4Maintenance operations must be done by a qualified
engineer.
4Only original spare parts must be used.
