physical, sensory or mental capabilities or lack of

experience and knowledge if they have been

given supervision or instruction concerning use of

the appliance in a safe way and understand the

hazards involved. Children shall not play with the

appliance. Cleaning and user maintenance

should not be carried out by children without adult

supervision.

1.1.1

Installation

Ensure sufficient space is available to allow correct

installation of the appliance.

See

Position of the appliance section (Installation and

Service Manual).

1.1.2

Water connections

The appliance is intended to be permanently

connected to the water mains.

Maximum / minimum water inlet pressure:

See

Technical specifications section.

The safety valve (not supplied) must be regularly

operated in order to remove limescale deposits and

ensure that it is not blocked.

Draining: shut off the domestic cold water inlet. Open

a hot water tap in the installation and then open the

drain valve on the cold water inlet. When the water

stops flowing, the appliance has been drained.

A pressure reducer (not provided) is necessary when

the supply pressure exceeds 80% of the calibration of

the safety valve or safety unit and it must be located

upstream of the appliance.

As water may flow out of the discharge pipe on the

pressure limiter device, the discharge pipe must be

kept clear and open.

1 Safety

7605313 - v10 - 28082018 5

Connect the pressure limiter device to a drain pipe,

kept open to the air, in a frost-free environment, and

at a continuous downward gradient.

1.1.3 Electrical connections

A disconnection device must be fitted to the

permanent pipes in accordance with installation rules.

If the power cable is damaged, it must be replaced by

the manufacturer, its after sales service or persons

with similar qualifications in order to obviate any

danger.

This appliance must not be powered through an

external switch, such as a timer, or be connected to a

circuit which is regularly switched on and off by the

electricity provider.

Install the appliance in accordance with national rules

on electrical installation.

The control panel for the appliance must remain

switched on to ensure that the impressed current

anode can operate. Failure to comply with this

instruction may cause deterioration to the water

heater tank and cancel its warranty.

4 Description of the product

4.1 Operating principle

The thermodynamic water heater uses unheated ambient air or outdoor air

to prepare domestic hot water.

The refrigerant circuit is a closed circuit in which the R-134a refrigerant

plays the role of an energy carrier.

The heat from the intake air is transferred to the refrigerant in the finned

heat exchanger at a low evaporation temperature.

The refrigerant is drawn in, in vapour form, by a compressor which raises it

to a higher pressure and temperature and sends it to the condenser. In the

condenser, the heat extracted in the evaporator and some of the energy

absorbed by the compressor are released into the water.

The refrigerant is depressurised in the thermostatic expansion valve and

then cooled. The refrigerant can again extract the heat contained in the

intake air from the evaporator.

water).

The number of baths is calculated based on a domestic hot water

temperature of 40 °C.

The tank is filled based on the set point temperature.

5.1 Commissioning the appliance

Caution

Initial commissioning must be performed by a qualified

professional.

Caution

After positioning the appliance, wait one hour before starting it up.

Carry out the commissioning operations in the following order:

1. Connect to the mains.

2. Check that no error codes or messages are shown on the display.

The domestic hot water temperature set point is factory-set to 55 °C

in comfort mode.

3. Select the BOOST ( ) operating mode.

If domestic hot water production is required, the compressor starts

up after 120 seconds.
