must not be undertaken by children without

supervision.

Applicable areas of use

The appliance is intended for use an appliance

for the production of domestic hot water: it must

be connected to a heating installation, and while

complying with the instructions, connected to

the drinking water network.

The intended use of the appliance includes the

following points:

•Following the instructions for operating,

installing and maintaining this appliance and

all of its components.

• Ensuring the compliance of the appliance to all

inspection and maintenance conditions which

are listed in this manual.

Danger of death by electrocution

• Touching live electrical wires can cause severe

bodily injury, and lead to death by electrocution.

All installation and maintenance work must be

carried out with the appliance switched o and

by a qualied professional. Before carrying out

any work on the appliance:

-Cut-o the electricity supply.

- Ensure that there is no possibility of the power

supply becoming active again.

-Wait at least 5 minutes for the capacitors to

lose their charge.

• Do not get water on any of the control or

electrical components. Always disconnect the

appliance from the electricity supply before

carrying out work on any of the electrical

components.

Danger of death if the pressure relief valves

are missing or defective

A defective pressure relief valve may prove

dangerous and could lead to burns or other

injuries by, for example, the pipes bursting.

The information presented in this document does

not contain all of the schematic diagrams needed

for a professional installation of the pressure relief

valves.

• Install the necessary pressure relief valves on

the circuit.

• Inform the user concerning the function and

the placement of the pressure relief valves.

• Respect all applicable national and international

regulations, standards and decrees.

Risk of material damage

The heat pump can only work when lled with

water. Never switch on the appliance if it is not

Note:

The Heat Pump is exclusively designed for heating purposes.

It cannot be used for cooling.

The manufacturer cannot be held responsible for any other usage

of the appliance.

4.1 - Operation

The Heat pump is a closed and pressurised system in which the

refrigerant serves as the medium for transferring energy.

The evaporator dis a cooling exchanger which draws calories from

the air. The humidity in the air condenses on contact with the cold

surface, and forms condensation which must be drained regularly

during operation of the Heat pump (evacuation in h).

The condenser eis a plated heat exchanger which allows to transfer

the heat towards the heating water of the installation g.

The operating range of the Heat pump ranges from an air

temperature of -20°C to 40°C.

It is FORBIDDEN:

•tooperatetheHeatpumpusing airintake

containing solvents or explosive materials.

• to use air intake containing grease, dust, or

aerosol particles.

• to connect vented exhaust hoods to the

appliance.

Use of the appliances are FORBIDDEN if

the installation is not lled with water.

4.2 - Accessories (included)

5.1 - Standard conguration

5 - INSTALLATION

•The Heat pump must be installed outside exclusively.

• Avoid any obstruction of the airow of the ventilator.

Ensure that there is nothing blocking the exchanger’s air circulation. Ensure that the Heat pump is placed so that

it is sheltered from dominant winds.

It is prohibited to install the Heat pump:

• In a non-ventilated room.

• Near sources of excessive heat, combustible

materials, or near ventilation points of adjacent

buildings.

• Near a kitchen or workshop exhaust ducts; this

can result in a mixture of oil and air settling onto

the heat exchanger ns which could hamper its

performance.

• In an area with ammable gaz, acidic substances,

or alkalines which could cause irreversible

damage to the copper-aluminium heat

exchanger.

PROHIBITED INSTALLATION

• Avoid installing the Heat pump in a

location subject to noise reverberation such

as near windows or near the corners of buildings.

• As the condensates draining trough slopes

downward, the Heat pump must be installed on a

level base.

• The Heat pump must be easily accessible so as to

facilitate access for inspections and maintenance.

5.2 - Placement

The Heat Pump is designed to be installed outdoors exclusively, while respecting a minimum of free space around the appliance in an area free

from excessive levels of dust. It should never be placed in an enclosed space.

The Heat Pump is designed to operate in rainy weather conditions, although it can be installed under a well-ventilated shelter (Withan opening

large enough to allow sucient air ow for intake and exhaust).

Regarding the fan, the free space from any obstacles must be at least 2m.

+6dB (A)

5.2.1 - Noise levels

The Heat Pump is equipped with a large diameter fan so as to allow for an appropriate air ow rate. This ow rate can rise up to 9.000 m3/h. The

fan speed is adjustable to limit the noise level.

Depending on the installation conditions, the noise levels may be dierent, in particular if the walls closest to the Heat Pump cause a reverberation

and amplication of noise.

The diagrams below show dierent installation examples for dierent placements.

5.2.2 - Safe area

The heat pump contains a ammable refrigerant. In case of leak, the refrigerant could accumulate near the ground (higher density than air). or

spread through openings in the building. In order to limit the risk of a toxic, suocating, explosive or dangerous atmosphere, a safety perimeter

must be established around the machine.This perimeter must not include a window, door, or any openings towards the interior of the building.

5.2.2.1 - Ground security area

Observe this area if the heat pump is in free eld.

- MANUAL HTi70 11  14 KW HEAT PUMPS -9

5.2.2.2 - Security area in front of a wall

This area must be respected if the heat pump is against a wall and close to the opening of a building.

5.4 - Condensate evacuation

When the appliance is operating in frost protection mode, the

condensed water must be drained o. In order for the condensates

to drain properly, the drainage trough and hole 1must be clean and

free of all debris (leaves, grass, etc...).

During cold weather, ice may form on the evaporator.The heat pump

has an automatic defrosting system to eliminate this phenomenon.

Do not use tools to remove the glass as this could damage the

evaporator.

The condensates can be connected to the drain with the optional

external defrost kit (Ref. 754101). It’s made up of a reinforced PVC

pipe and a heating cord allowing drainage in freezing weather.

It’s also possible to let the condensates ow freely at the back of

the heat pump. In this case, it’s necessary to provide in the ground

a device allowing a drainage of water in depth.

5.3 - Setting up

The Heat pump must be installed on a hard and stable base, which is suciently raised from ground level to

avoid risks of damage in case of ooding or snow.

- Put the heat pump in his 4 attachment tabs (b)

- If needed, attach the heat pump to the oor using these 4 xing lugs (c). (ref. 754601) screws not supplied.
