1 Safety

1.1 Safety

Danger

This appliance can be used by children aged from

8 years and above and persons with reduced

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

4 300026515 - v10 - 28082018

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.

Wiring diagram:

See

Wiring diagram section (Installation and Service

Manual).

Others

Danger

If flue gas is released or there is a refrigerant

leak:

Do not use a naked flame, do not smoke, do not

operate electrical contacts or switches (doorbell,

light, motor, lift, etc.).

frost injuries.

Locate the probable leak and seal it

immediately.

Warning

According to the appliance settings:

Do not touch the refrigerant connection pipes

with bare hands when the appliance is

operating. Risk of scalding.

Caution

Do not neglect to service the appliance.

In order to limit the risk of being scalded, a

thermostatic mixing valve must be installed on

the domestic hot water flow pipes.

4.3 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.

Minimum distance to be observed for the ducts if intake and backflow are done on the same

façade: 700 mm.

Important

Risk of inconvenience in Eco operating mode: the immersion heater never

switches on. In addition, when the outdoor temperature is low, the output

of the thermodynamic water heater is reduced. The domestic hot water

set point temperature is not reached.

3 Habitable room Can obtain free heat from the garage.

4 Laundry room Unheated room.

Enables the dehumidification of the room and recovery of the energy wasted by washing

machines and tumble dryers.

5 Via crawl space

Connection to the crawl space is possible if the volume is greater than 30 m

The crawl space must be frost-free (temperature > 1 °C)

Important

If the crawl space is poorly insulated, thermal losses from the home will

be greater.

Position of the appliance in a cupboard

1 With EH434 (reduced elbow kit): 800 mm x 800 mm - ducted
