1 Description of the unit
1.1 Packaging
• 1 package : Heat pump and outdoor sensor.
• 1 package : Flexible connections, filter valves,
insulation valves, Brine circuit expansion vessel,
Heating circuit expansion vessel, nipples and joints.
1.2 Definitions
- Water/water / Brine/water : The heat contained in the
ground (soil, rock or a ground water) is the source of
energy. This energy is collected by the brine circuit
(in which circulates the glycol water) and then
transmitted to the water of the heating circuit.
- Brine circuit : The recovery of heat from the ground
(soil, rock or a ground water) takes place by means
of a brine in a closed circuit containing glycol water.
There are two main types of brines in the ground:
horizontal brine circuit or boreholes.
- COP (coefficient of performance): This is the
ratio between the energy transmitted to the
heating circuit and the electrical energy input.
Outdoor temperature has little influence on COP of
ground source heat pump.
Scope of application
This heat pump provides:
- Heating in winter,
- Control of two heating circuits*,
- Production of domestic hot water* (if DHW tank is

1.4 Operation principle
The ground source heat pump uses the energy stored
in rock, ground or water to provide heat to a building
and to sanitary water.
A ground source heat pump is made of 3 main
components:
- The heat pump itself,
- The brine circuit,
- The heating emitters (radiators, heating floor…).
• In the brine circuit: energy is taken from the rock,
ground or water by the brine and then released to
the refrigerant circuit. Brine circuit can be a surface
collector or several bore holes collector.
• The heat pump is made of a refrigerant circuit (ref. 1,
figure 4, page 7) which contains the following
components :
- Evaporator (ref. Ev, figure 7, page 9) : The heat
removed from the ground by the brine is released to
the refrigerant. Refrigerant boiling point is lower than
the brine temperature, the refrigerant moves from
liquid to gaseous states.
- Compressor (ref. Cp, figure 7, page 9) : Pressure
and temperature of the refrigerant are increased.
- Condenser (ref. Cn, figure 7, page 9) : The
refrigerant releases its energy to the heating circuit water.
The refrigerant moves from gaseous to liquid states.
- Expansion valve (ref. Dt, figure 7, page 9) :
Pressure and temperature of the refrigerant are lowered.
• The heat pump is equipped with a control system that
set the heating circuit water temperature according
to outdoor temperature. (heating curves). Room
sensor (optional) can be installed; it corrects the water
temperature according to indoor temperature when
needed.
• The heat pump is equipped with a back-up heater that
provides additional heat when needed.
• The heat pump, as an option, can be ducted to a boiler
which will provide the additional heat when needed.
• Control system function
- The average leaving water temperature of the heating
circuit is controlled by the heating curve.
- Indoor temperature can be scheduled (week/day),
several temperatures can be set.
- Switching from winter/summer operation modes is
automatic.
- Management of back up heater
- Management of ducted boiler* (optional)
- Room sensor*: corrective action on heating curve.
- 2nd heating circuit control
- Domestic hot water: heating schedule, management
of DHW circulating pump.
-Buffer tank* control (mandatory with radiators or
several heating zones / 15l/kW).
*in case heat pump is equipped with the correct option or kit.
• Fan-coil with integrated control system
Do not use a room sensor in the area equipped with fan
coils.
• Protection functions
- Anti-legionella cycle for domestic hot water*.
- Anti-freeze protection: when leaving water temperature
of the heating circuit reaches 5°C, anti-freeze
protection is activated (provided power supply is on).
• Domestic hot water (DHW) operation*
2 DHW temperatures can be set : nominal temperature
(line 1610, 55°C) and reduced temperature (line 1612,
40°C).
Factory schedule for DHW operation (lines 560, 561, 562)
set nominal temperature from 0:00 to 5:00 and from 14:30
to 17:00. Reduced temperature is set the rest of the day.
This schedule optimises the electrical energy consumption
and insures hot water availability and heating comfort.
Setting of reduced temperature can be useful to provide
often witch on of the DHW production.
DHW production is activated when DHW temperature is
12°C below the set temperature.
DHW heating can be completed by water tank back-up
heater when needed.
To insure DHW temperature higher than 45°C, it is
necessary to connect water tank back up heater.
Depending on the DHW schedule (line 1620), comfort
temperature will be maintained 24h/day or only during the
night or as defined in the schedule.
DHW production takes priority over heating. Nevertheless,
in case of simultaneous demand for DHW and heating,
the control system manages both heating times to insure
comfort.
A function to switch from “reduced” to “comfort” is available
on the user interface (see ref. 8, figure 23, page 28).
Anti-legionella cycles can be scheduled.
1.5 Performances
1.5.1 Running-in period
Compressor needs a running-in period.
Rating performances will be reached after a minimum of
48 hours running operation.
1.5.2 Expansion valve setting
Your appliance has been factory set to insure safe
operation and optimum performance
Interventions on refrigerant load or expansion valve
setting could be authorised only in case of extremely
stable hot or cold sources and under manufacturer
control.
Do not proceed to any changes without
agreement from manufacturer. Any mishandling
can cause serious damages.

2.2.3 Handling
The ground source heat pump should not be laid down
during transportation. Lying down transportation may
damage internal pipes and compressor suspension.
Any damage caused by lying down transportation are
not covered by the warranty. On short distances, it is
possible to use a hand truck without exceeding a 45°
angle.
If necessary, the ground source heat pump can be
tilted only when manual handled (to go through a door,
use a staircase). This operation must be conducted
very carefully and the appliance must be immediately
restored to upright position.
2.3 Installation location
The choice of the location for installation is particularly
important insofar as any later movement is a tricky
operation requiring the intervention of a qualified person.
Choose the location of the heat pump after discussion
with the customer.
The heat pump should be placed on a clean level slab
to support the weight of the machine.

2.5 Brine circuit Installation
2.5.1 Dimensioning of the brine circuit
• Refer to the instructions supplied with the Brine circuit
kit.
The Brine circuit must be sized to pass the flow rate and
collect the calories according to the ground source HP
characteristics.
The length of the Brine circuit can vary
depending on soil type, climate zone, or heating
system (radiators, heated floor, etc..).
With the Brine circuit kit, according to the available
surface, the soil or earthmoving equipment available,
it is possible to realize different geometries.
Likewise if the length of delivered tube corresponds to
the worst case (excluding extreme cases such as dry
sand, pozzolan, etc..), according to the type of the soil
it is possible to modulate the loop surface and the total
length used.
The diameter of the pipe between the heat pump and
the brine circuit collector, must be at least to 1'1/4 inch
(33x42 mm).
Calculate the pipes diameter according to the flow rates
and lengths of hydraulic networks.
Tightening torque : 15 to 35 Nm.
The use of glycol is mandatory. Use monopropylene
glycol only. The recommended concentration is 30%
minimum.
Never use monoethylene glycol.

2.6 Installation of the Heat Pump
2.6.1 Installation precautions
In accordance with EN 378-1 -2017 standard
(Refrigerating systems and heat pumps - Safety and
environmental requirements), the system's hydraulic
unit and all refrigeration connections passing through
inhabited areas must comply with the minimum room
volume requirements shown hereafter.
The minimum volume of a room (in m3) is calculated
using the formula: "fluid fill load" (in kg) / 0.39.
Alternatively, you must ensure that :
- The location has natural ventilation through another
room where the combined volume of the two rooms is
greater than "liquid fill load" (in kg) / 0.39 kg/m3. The
opening between the two rooms must have a door
clearance of at least 1 cm.
- Or that the location is mechanically ventilated.

2.7 Hydraulic connection
of the heating circuit
2.7.1 General
The tightness operation shall follow the plumbing state
of the art:
- Use suitable seals (fibre seals, o-rings).
- Use Teflon tape or hemp.
- Use sealing paste (synthetic depending on the case).
The use of glycol is not necessary (except in special cases).
If you are using a glycol/water mix, an annual check of
the quantity of glycol is necessary. Use monopropylene
glycol only. The recommended concentration is 30%
minimum. Never use monoethylene glycol.
In some installations, the presence of different
metals can cause corrosion problems; the
formation of metal particles and sludge in the
hydraulic circuit can appear.
In this case, it is advisable to use a corrosion
inhibitor in the proportions indicated by its
manufacturer.
- Please refer to the chapter "Treatment of domestic
and heating water" in our price catalogue.
It is also necessary to ensure that the treated
water does not become aggressive.
2.7.2 Rinsing out the installation
Before connecting the heat pump to the heating circuit,
rinse out the heating system correctly to eliminate
any particles that may affect the appliance's correct
operation.
Do not use solvents or aromatic hydrocarbons (petrol,
paraffin, etc.).
Add an alkaline product to the water and a dispersant.
Rinse the installation several times before filling it
definitively.
2.7.3 Connection
The heating circuit pump is integrated to the heat pump.
- Connect the central heating pipes on the heat pump in
accordance with the flow direction.
The pipe diameter between the heat pump and the heat
collector must be at least one inch (26x34 mm).
Calculate the diameter of the pipes according to the
flow rates and the lengths of the hydraulic systems.
Tightening torque: 15 to 35 Nm.
- Use connection hoses to avoid transmitting noise and
vibrations to the building.
- Install the filter valve on the Heating return circuit in
the recommended sense.
- Install dirt separator on the Heating circuit return.
- Install the expansion vessel of the heating circuit.
- Connect the drains from the drain valve and the safety
valve to the main sewer system (except when glycol
is used).
2.7.4 Filling and venting the installation
Check the pipe connection, the tightness of the
connectors and the stability of the heat pump.
Check the direction in which the water is circulating and
that all the valves are opened.
Proceed the installation filling.
Do not run the circulating pump while filling. Open all
the drain valves in the installation and the bleeder valve
for the hydraulic unit (P) to remove the air contained in
the pipes.
Close the drain and bleeder valves and add water until
the pressure in the hydraulic circuit reaches 1 bar.
Check that the hydraulic circuit has been correctly
vented.
Check there is not a leak.
After the "Commissioning", page 25, once the
machine has started, vent again.
2.7.5 Connection of Fan-coil
or Dynamic radiator circuit
A buffer tank shall be installed
(minimum capacity 15l/kW).
