3 Description
3.1 General description
The ALEZIO heat pump comprises:
4A reversible outside module for energy production in hot or cold
mode.
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 inside module handles domestic hot water production.
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.
4The steel tank is lined with food quality standard enamel vitrified
at 850°C, which protects the tank from corrosion.
4The coil-shaped heat exchanger welded into the tank is made of
smooth piping, its external surface, which comes into contact with
drinking water, being enamelled.
4The appliance is insulated by CFC-free polyurethane foam, which
reduces heat losses to a minimum.
4The outside casing is made of painted steel sheeting.
4The tank is protected against corrosion by a magnesium anode.

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.
5.2 Periodic checks
WARNING
Only qualified professionals are permitted access to the
inside of the appliance.
If the pressure gauge is not accessible, contact the
installer.
4Have the installation's water pressure checked.
If the water pressure is lower than 1 bar, more water should
be added. If necessary, top up the water level in the heating
system (recommended hydraulic pressure between 1,5
and 2,0 bar).
¼ See chapter: "Top up the installation with water",
page 20.
4Carry out a visual check for the presence of any water leaks.
4Open and close the radiator valves several times a year (this
prevents the valves from seizing up).
4Clean the outside of the heat pump using a damp cloth and a mild
detergent.
CAUTION
Only qualified professionals are permitted to clean the
inside of the appliance.
