4 Description of the product

4.1 General description

The hybrid heat pump comprises:
an indoor module for controlling the heating circuit water a reversible outdoor unit for the production of energy in heating mode and in cooling mode.
The indoor module comprises:
a hydraulic module, which integrates the functions for the heat pump's indoor module a wall-mounted condensing gas boiler and a connection kit, installed on the front of the hydraulic module
The indoor module and the outdoor unit are connected by means of refrigerant and electrical connections.
The system offers the following advantages:
An extremely compact solution which can be easily integrated into the most confined areas of any residence. A single control system to manage the entire system (heat pump and boiler). Choose the type of energy according to cost or CO2 emissions.
The heating circuit is housed in the insulated volume within the home. Thanks to the DC inverter system, the hybrid heat pump modulates its output to adapt to the needs of the residence. The control system uses the outside sensor to adjust the temperature of the heating circuit according to the outside temperature. The outer casing of the hydraulic module is made of painted steel sheeting.

4.2 Operating principle

Heat pumps in the Alezio G hybrid range extract heat from the air and return it to the heating circuit via the refrigerant fluid. The efficiency of a heat pump is expressed in the form of a coefficient of performance (COP), defined as the ratio between the heat provided and the power consumed.
The heat pump comprises an evaporator, a compressor, a condenser and an expansion valve. The indoor module includes the condenser. The other components (evaporator, compressor and expansion valve) are located in the outdoor unit.
1. The refrigerant fluid in the circuit is converted from the liquid state to the gaseous state in the evaporator, making it possible to recover heat from the air.
2. The compressor increases the fluid pressure, which thus increases the temperature.
3. In the condenser, the fluid transfers the heat to the heating circuit while converting to the liquid state.
4. The refrigerant passes through the thermostatic expansion valve and returns to the initial state at low pressure and low temperature before returning to the evaporator.

8.1 General

8 Maintenance

Maintenance operations are important for the following reasons:
To guarantee optimum performance. To extend the life of the equipment. To provide an installation which offers the user optimum comfort over time.
Caution Only qualified professionals are authorised to carry out maintenance work on the heat pump and the heating system.
Danger of electric shock Before any work, switch off the mains electricity to the heat pump and the hydraulic back-up if present.
Caution 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 pressures, which may cause serious injuries.
Caution Do not drain the installation, except in cases of absolute necessity. E.g.: several months' absence with the risk of temperatures in the building falling below freezing.
8.1.1

Troubleshooting

Caution All work on the refrigeration circuit must be done by a qualified professional, 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.
Caution This appliance is fitted with pressurised equipment, including the refrigeration pipes.
Caution Use only original parts to replace a defective refrigeration component.
Caution Use only dehydrated nitrogen for detecting leaks or for pressurised tests.
Caution Only a qualified professional is authorised to set, correct or replace the safety devices.
8.2

Standard inspection and maintenance operations

An annual inspection with tightness check is obligatory. Schedule a service by a qualified professional at a cold time of the year to check the following points:
1. Operation of the installation.
2. Thermal output, by measuring the difference in temperature between heating flow and return.
3. The setting for the safety thermostats.

8.2.1 Checking the water pressure

1. Check the water pressure.
The water pressure must be at least 0.8 bar.
2. If the water pressure is lower than 0.8 bar, top up the central heating system.
8.3

Cleaning the casing

1. Clean the outside of the appliance using a damp cloth and a mild detergent.

8.4 Venting the system

Fig.48 Venting the system
Any air in the boiler, the pipes or the valves must be removed in order to prevent unwanted noises that may occur during heating or when tapping water. Proceed as follows:
1. Open the valves of all the radiators connected to the system.
2. Set the room thermostat to the highest possible temperature.
3. Wait until the radiators are warm.
4. Ensure that the boiler is disconnected from the power supply.
5. Wait approximately ten minutes, until the radiators feel cold.
6. Vent the radiators. Work from the lowest to the highest.
7. Open the venting valve with the bleed key, keeping a cloth pressed against the vent.
Warning The water may still be hot.
8. Wait until water comes out of the venting valve and then close the venting valve.
9. Turn the boiler on.
A four-minute venting cycle is performed automatically.
10. After venting, check that the water pressure in the system is still adequate. If necessary, top up the central heating system.
11. Adjust the room thermostat or temperature control.

11.1 Energy savings

Energy-saving advice:
Do not block ventilation outlets. Do not cover the radiators. Do not hang curtains in front of the radiators. Install reflective panels behind the radiators to prevent heat losses. Insulate the pipes in rooms that are not heated (cellars and lofts). Close the radiators in rooms not in use. Do not run hot (or cold) water pointlessly. Install an energy-saving shower head, which can save up to 40 % energy. Take showers rather than baths. A bath consumes twice as much water and energy.
