1 Safety
1.1 General safety instructions
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 shall
not be made by children without supervision.
Warning
In the event of a refrigerant leakage:
Switch off the appliance.
Open the windows.
Do not use a naked flame, do not smoke, do not operate
electrical contacts.
Avoid contact with the refrigerant. Danger of frost injuries.
Locate the probable leak and seal it immediately. Use only
original parts to replace a defective refrigeration component.
Do not touch the refrigeration connection pipes with your bare hands while
the heat pump is running. Danger of burn or frost injury.
Warning
To limit the risk of burns, install a device limiting the temperature
of the hot water, such as a thermostatic mixing valve, for example.
France: Order of 30th November 2005 modifying article 36 of the
order of 23rd June 1978 relating to fixed installations for heating
and the supply of domestic hot water in residential buildings,
offices, or establishments open to the general public.
Take precautions with the domestic hot water. Depending on the heat
pump settings, the domestic hot water temperature may exceed 65 °C.
Do not touch radiators for long periods. Depending on the heat pump
settings, the temperature of the radiators may exceed 60 °C.
The installation must satisfy all aspects of the rules in force in the country
that govern work and interventions in individual homes, blocks of flats or
other buildings.
Respect the minimum and maximum water pressure and temperature
(70°C) to ensure the appliance operates correctly. See chapter on
Technical Specifications.
Install the appliance in accordance with national rules on electrical
installation.
A disconnection device must be fitted to the fixed wiring in accordance
with installation rules.
If a power supply cable comes with the appliance and it turns out to be
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 be connected to the protective earthing.
Earthing must comply with the prevailing installation standards.
Earth the appliance before making any electrical connections.
Type and calibre of the protective equipment: refer to the "Recommended
cable cross-sections" chapter. See the Installation and Service Manual.
To connect the appliance to the electricity mains, refer to the "Electrical
Connections" chapter. See the Installation and Service Manual.
If the appliance is not wired in the factory, carry out the wiring according to
the wiring diagram described in the chapter Electrical Connections. See
the Installation and Service Manual.
1 Safety
7611407 - v07 - 14022022 GSHP 5

In order to avoid the danger of an unexpected thermal circuit breaker
reset, 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.
Separate the very low voltage cables from the 230/400 V power supply
cables.
Danger
Before any wiring work on the electrical circuit, switch off the
power supply, check that no voltage is present and secure the
circuit breaker with a circuit breaker lockout.
Before any work on the appliance, carefully read all documents that
accompany the product. These documents are also available on our
website. See the last page.

1.2 Recommendations
Important
Keep this document close to the place where the appliance is
installed.
Important
Allow the space required to correctly install the heat pump. Refer
to the Overall space needed for the heat pump section in the
installation and service manual.
Important
Only qualified professionals are authorised to assemble, connect,
commission and service the installation.
Caution
Remove the heat pump casing only to perform maintenance and
repair work. Always put the casing back in place after such work.
Important
Never remove or cover the data plates and labels affixed to the
heat pump.
The data plates and labels must be legible throughout the entire
lifetime of the heat pump. Immediately replace damaged or
illegible instructions and warning labels.
Warning
Do not bring the heating water and the domestic water into contact
with each other in the the heating system.
Caution
To enjoy warranty cover, no modifications must be made to the
heat pump.
Caution
The frost protection function does not work if the heat pump is
powered off.

Caution
It is preferable to use HOLIDAYS mode rather than switching off
the heat pump to handle the following functions:
Unblocking the circulating pumps,
frost protection.
1.3 Specific safety instructions
Warning
Refrigerant fluid and pipes:
Use only R410A refrigerant fluid to fill the installation.
Use tools and pipe components especially designed for use with
R410A refrigerant fluid.
Use copper pipes deoxidised with phosphorus to carry the
refrigerant fluid.
Store the refrigerant connection pipes away from dust and
humidity (risk of damage to the compressor).
Do not use a load cylinder.
Protect the heat pump components, including the insulation and
structural elements. Do not overheat the pipes as brazed
components may cause damage.
Contact between the refrigerant fluid and a flame may result in
emissions of toxic gases.
1.3.1 Refrigerant R410A
Product identification
Emergency call: Anti-poison Centre INRS/ORFILA [phone]
Hazard identification
Effects harmful to health:
The vapours are heavier than air and may lead to asphyxia owing to
reduced oxygen levels.
Liquefied gas: contact with the liquid may cause serious frost burn and
eye injuries.
Product classification: this product is not classified as a "hazardous
preparation" according to European Union regulations.
If the R410A refrigerant is mixed with air, it may cause pressure surges in
the refrigeration pipes and lead to an explosion and other hazards.
Composition of / Information on the ingredients
Chemical nature: R-410A is composed of Difluoromethane R32 and
Pentafluoroethane R125
Tab.1 Composition of R-410A fluid
Name Proportion Number CE Number CAS
Difluoromethane R32 50% 200–839–4 75-10-5
Pentafluoroethane R125 50% 206-557-8 354-33-6
The Global Warming Potential (GWP) of the R410A is 2088 following the
IPCC fourth assessment report (1924 following IPCC fifth assessment
report).

Avoid contact with the skin and eyes.
Do not intervene without appropriate protective equipment.
Do not inhale the vapours.
Evacuate the hazardous area.
Stop the leakage.
Eradicate all sources of ignition.
Ventilate the spillage area mechanically.
Cleaning / decontamination: allow any residual product to evaporate.
In the event of contact with the eyes: Rinse immediately with water, holding the eyelids well
apart (for at least 15 minutes). Consult an ophthalmologist immediately.
Handling Technical measures: ventilation
Precautions to be taken:
No smoking.
Prevent the build-up of electrostatic charges.
Work in a well ventilated place.
Personal protection Respiratory protection:
If ventilation is insufficient: AX type cartridge mask.
In confined spaces: self-contained breathing apparatus.
Hand protection: protective gloves in leather or nitrile rubber.
Eye protection: safety glasses with side protection.
Skin protection: clothing made principally of cotton
Industrial hygiene: do not drink, eat or smoke at the place of work.
Considerations on disposal Important
Disposal must be done in compliance with prevailing local and national
regulations.
Product waste: consult the manufacturer or the supplier for information on recovery or recy
cling.
Soiled packaging: reuse or recycle after decontamination. Destroy in authorised installa
tions.

4 Description of the product
4.1 General description
The heat pumps in the GSHP range are geothermal heating systems
based on so-called mixed “Water-Water’’ technology.
The heat pumps in the GSHP range comprise three main elements that
enable them to heat a home whilst being as environmentally friendly as
possible:
An underground collector
One or more heating circuits
A heat pump
The heat pumps in the GSHP range have the following specifications:
Compact appliance ready for connection.
Single phase or three-phase power supply.
Integrated expansion vessel (models: GSHP 5 MR-E, GSHP 5 TR-E,
GSHP 9 MR-E, GSHP 9 TR-E, GSHP 12 MR-E, GSHP 12 TR-E, GSHP
15 TR-E).
Reversible heat pump.
Installation inside the building only.
Silent running.
Casing in soundproofed thermo-lacquered sheet steel.
2 plate exchangers.
Control panel with integrated control system.
