4 Description of the product

4.1 General description

The hybrid heat pump comprises:

an indoor module for the production of 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 groups together the functions for the heat
pump's indoor module
a wall-mounted condensing gas boiler, installed on the front of the hy
draulic module

The indoor module and the outdoor unit are connected by means of refrig
erant 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.
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 sheet
ing.

4.2 Operating principle

Heat pumps in the Alezio G hybrid range extract heat from the air and re
turn it to the heating circuit via the refrigerant. The efficiency of a heat
pump is expressed in the form of a coefficient of performance (COP), de
fined 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 this 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.

7.1 General

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
Maintenance work must be carried out by a qualified professional.

Danger
Before any work, switch off the mains electricity to the heat pump
and the hydraulic or electrical back-up if connected.

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 necessi
ty. E.g.: several months' absence with the risk of temperatures in
the building falling below freezing.

7.1.1 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 nitro
gen). 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 compo
nent.

Caution
Use only dehydrated nitrogen for detecting leaks or for pressur
ised tests.

Caution
The safety devices may only be set, corrected or replaced by a
qualified professional.

7.2

Standard inspection and maintenance operations

An annual inspection with tightness check is obligatory. Schedule a serv
ice by a qualified professional at a cold time of the year to check the fol
lowing points:

1. Have a qualified professional check that the installation is perform
ing correctly at each periodic service.

2. Have a qualified professional check the heat output by measuring
the difference in temperature between heating flow and return.

3. Have a qualified professional check the safety thermostat settings.

7 Maintenance

7611444 - v02 - 11122015 43

7.2.1 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.

7.3

Cleaning the casing

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

7.4

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 ad
equate. If necessary, top up the central heating system.

11. Adjust the room thermostat or temperature control.

8.1 Error codes

8.1.1 Error codes on the PCB EHC-02

An A.xx.xx or H.xx.xx error code corresponds to a temporary status of the
hybrid heat pump after a fault is detected. If an error code remains after
several automatic start-up attempts, the hybrid heat pump switches to fail
ure mode. Failure mode is indicated by a E.xx.xx type fault code. The hy
brid heat pump only restarts once the fault is resolved.

Note
An error code is linked to a PCB. If an error code is displayed,

11.1 Energy savings

Tips on saving energy:

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).
Turn off the radiators in rooms not being used.
Do not run hot (or cold) water pointlessly.
Install a water-saving shower head to save up to 40% energy.
Take showers rather than baths. A bath consumes twice as much water
and energy.
