1.1 Packaging
• 1 package: Outdoor unit
• 1 package: Hydraulic unit and outdoor sensor.
1.2 Denitions
- Split: The heat pump is formed by two elements (an
outdoor unit to be installed outdoors and a hydraulic
unit to be installed indoors).
- Air/water: The outdoor air is the energy source. This
energy is transmitted to the heating water by the heat
pump.
- Inverter: The speeds of the fan and the compressor
are modulated to suit the heat requirements. This
technology saves energy and permits operation with
a single phase power supply, regardless of the power
rating of the heat pump, by avoiding high current
demands on start-up.
-COP (coe󰀩cient of performance): this is the ratio
between the energy transmitted to the heating circuit
and the electrical energy consumed.
Optional equipment
• Wired room thermostat UA55 (ref. 076 310)
for correcting the ambient temperature.
• HP Pack (ref. 602 231)
for reporting consumption per use (Heating / DHW).
• Dual circuit kit (ref. 076446)
for connecting 2 heating circuits.
• Cooling kit (ref. 076 313).
• Anti-vibration pads (ref. 523 574).
• White PVC oor support (ref. 809 532) or
Black rubber oor support (ref. 809 536).
• Condensate drain pan (ref. 074 008).
• Container bottom tracer (ref. 809 644).
Scope
This heat pump provides:
- Heating in winter,

Loria duo 6000 heat pump

1.5 Operating principle
The heat pump transmits the energy contained in the
surrounding air into the residence to be heated.
The heat pump consists of four main elements, in which
a refrigerant (R410A) circulates.
- In the evaporator (reference 12, gure 6, page 9):
The energy is taken from the surrounding air and is
transmitted to the refrigerant. Because it has a low
boiling point, it changes from liquid state to vapour
state, even in cold weather (down to -15°C outdoor
temperature).
- In the compressor (reference 9, gure 6, page 9):
The vaporised refrigerant is brought to high pressure
and takes on more calories.
- In the condenser (reference 23, gure 6, page 9):
The energy in the refrigerant is transmitted to the
heating circuit. The refrigerant returns to its liquid state.
- In the expansion valve (reference 8, gure 6, page 9):
The liqueed refrigerant is brought back to low pressure
and returns to its initial temperature and pressure.
The heat pump has a regulator that controls the indoor
temperature based on the measurement of the outdoor
temperature, known as weather-dependent control.
The room thermostat (optional) corrects the weather-
dependent setpoint.
The hydraulic unit is equipped with an electrical back-up
system, which is designed to provide additional heat
during the coldest periods.
• Regulation functions
- The initial temperature of the heating circuit is
controlled by the weather-dependent setpoint.
- The power of the outdoor unit is modulated according
to the need via the "inverter" compressor.
- Control of the electrical back-up.
 Additional heating when the HP alone is
insu󰀩cient.
 Assist mode.
- The daily timer programme enables you to dene
the periods for comfortable or reduced ambient
temperature.
- Switching between summer/winter operation is
automatic.
- Room thermostat*: The room thermostat corrects the
weather-dependent setpoint.
- Domestic hot water.
• Protection functions
- Compressor protection via heating back-up.
- Heat exchanger protection via heating back-up.
- Legionella cycle for domestic hot water.
- Minimum ow detection.
- Sediment trap to protect the HP heating circuit
- Frost protection.
- Safety thermostats for electrical back-ups.
* When the heat pump is equipped with options and associated kits.

• Domestic hot water (DHW) operating principle.
Two domestic hot water (DHW) temperatures can be
set:
- Comfort temperature ( ) and
- Reduced temperature ( )
(See user interface description page 40 or room
thermostat):
The DHW programme ( ) is set by default
to a comfort temperature ( ) according to 2 pre-set
phases (see "DHW time programme", page 45) and
a reduced temperature ( ) for the rest of the day,
which optimises electricity consumption while ensuring
comfortable levels of hot water and heating.
The production of domestic hot water (DHW) is triggered
when the temperature in the tank falls 7°C below the
temperature setpoint.
The heat pump produces domestic hot water (DHW),
which is then heated further, if required, by the electrical
back-up system inside the tank.
To ensure that the DHW setpoint is reached, the
electrical back-up system must be left on.
DHW production takes priority over heating;
nevertheless the production of DHW is controlled by
cycles that control the times assigned to the heating
and the production of DHW in the event of simultaneous
demand.
A DHW boost function is available (on the user interface:
user level , setting "95", page 47) or on the room
thermostat page 41. This DHW boost is used to heat
the DHW to the comfort temperature at any time of day.
The boost function is cancelled automatically when the
demand for hot water has been met.
Legionella cycles may be authorised (see parameter:
Legionella function No. "73", page 46).
• Dynamic radiators or fan-coil heaters with integrated control system
Do not use a room thermostat in the zone concerned.

position.
In the event of disagreement, write to the carrier within
48 hours mentioning all reserves and send a copy of
this letter to the After Sales Department.
2.2.2 Handling
The outdoor unit must not be in a horizontal position
during transport. Transport in a horizontal position may
damage the appliance by moving the refrigerant and
damaging the compressor's suspensions. Damage
caused by transportation in a horizontal position is
not covered by the warranty.
If necessary, the outdoor unit may be tilted during manual
handling (to go through a door or use a staircase).
This operation must be conducted very carefully and the
appliance must be immediately restored to the upright
position.
2.2.3 Containing the refrigerant circuits
All refrigerant circuits are susceptible to contamination
from dust and moisture. If such pollutants enter the
refrigeration circuit, they can a󰀨ect the reliability of the
heat pump.
"Please ensure correct containment of the
connections and refrigerant circuits (hydraulic
unit, outdoor unit).
"In the case of subsequent failure and after
inspection, the detection of moisture or
foreign objects in the compressor oil would
systematically make the warranty null and void.
- Check upon receipt that the refrigeration circuit caps
and connections mounted on the hydraulic unit and
outdoor unit are properly sealed and locked (cannot
be loosened with bare hands). If this is not the case,
tighten them using a wrench.
- Also check that the refrigerant connections are sealed
(plastic caps or tubes crushed at the ends and brazed).
If the caps must be removed during installation (for
example tubes cut), reposition them as quickly as
possible.

2.3 Positioning the refrigerant connections
"Manipulate the pipes and pass through slabs
or walls with protective plugs in place or after
brazing.
"Keep the protective caps or brazed ends until
commissioning the product.
The outdoor unit and the hydraulic unit must only be
connected using copper connections (refrigerating
grade), insulated separately.
Comply with with the pipe diameters (gure 18, page 21).
Observe the maximum and minimum distances
between the hydraulic unit and the outdoor unit (gure
18, page 21); the guarantee of the performances and
the system's service life depend on this.
The minimum length of the cooling connections is 5
m for correct operation.
The appliance's warranty will become void if it is applied
with cooling connections that are shorter than 5 m
(tolerance +/-10%).
If the refrigeration connections are exposed to
weathering or UV rays and the insulation is not UV-
resistant, protection must be provided.

2.4 Installing the outdoor unit
2.4.1 Installation precautions
"The outdoor unit must only be installed
outdoors. If a shelter is required, it must have
broad openings on all 4 walls and comply with
the installation clearances.
• Choose the installation site after talks with the
customer.
• Prioritise a site that is sunny and sheltered from strong
cold predominant winds (mistral, tramontane, etc.).
• The unit must be easily accessible for future installation
and maintenance work.
• Ensure that the connectors can be easily connected to
the hydraulic unit.
• The outdoor unit can be exposed to bad weather,
however avoid installing it in places where it will
become dirty or have excessive water dripping onto it
(for example under a leaky drainpipe).
• Water may be released from the outdoor unit when in
operation. Do not install the appliance on a terrace;
install it in a well-drained location (bed of gravel or
sand). If installed in a region where the temperature
may drop below 0°C for a long period of time, check
that the ice does not cause any danger. A drainage
pipe can also be connected to the outdoor unit
(see page 17).
• Nothing should obstruct the air from circulating through
the evaporator and out of the fan.
• Keep the outdoor unit away from sources of heat or
inammable products.
• Ensure that the appliance does not disturb neighbours
or users (noise level, draughts caused, low temperature
of the air blown causing a risk of freezing plants in its
path).
• The surface on which the outdoor unit is mounted
must:
- Be permeable (earth, gravel bed...),
- Support its weight comfortably,
- Allow for secure attachment,
- Not transmit any vibrations to the residence.
Anti-vibration pads are available as an optional extra.
• The wall bracket cannot be used in conditions likely to
transmit vibrations, where installation on the ground is
preferred.

2.4.2 Positioning the outdoor unit
The outdoor unit must be raised by at least 50
mm from the ground. In snowy regions, this height
must be increased but must not exceed 1.5 m
(gure 13).
- Fasten the outdoor unit using screws and elastic
tightening or toothed lock washers to prevent them
from coming loose.
"Warning In regions with heavy snowfall, if the
outdoor unit's entrance and exit are blocked by
snow it may be di󰀩cult to heat up and may probably
cause a breakdown. Build a canopy or position the
unit on a high stand (local conguration).
- Put the appliance on a solid support to minimise
impact and vibration.
- Do not set the unit directly on the ground as this may
generate disruptions.
2.4.3 Connecting the condensate evacuation pipe
(see gure 13).
"The outdoor unit can generate a large volume of
water (called condensate).
If an evacuation pipe must be used:
- Install the condensate drain pan (BR) (optional, see
page 4).
- Use the elbow provided (C) and connect a hose of 16
mm diameter to discharge the condensates.
- Use the plug(s) supplied (B) to plug the orice of the
condensate drain pan.
Provide for the gravitational discharge of the
condensates (waste water, rainwater, gravel bed).
"If the appliance is installed in a region where the
temperature may fall below 0°C for long periods,
t the drain hose with a trace heater to prevent it
from icing over. The trace heater must not only
heat the drain hose but also the bottom of the
appliance's condensate drain pan.

2.5 Installing the hydraulic unit
2.5.1 Installation precautions
• Choose the installation site after talks with the
customer.
• The room where the appliance operates must comply
with the regulations in force.
• To ease maintenance operations and provide access
to the various parts, su󰀩cient space should be left
around the hydraulic unit.
• 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: "uid ll 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 ll 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.
• Be careful to keep the heat pump away
from inammable gas during installation,
in particular when it requires brazing.
The appliances are not reproof and should therefore
not be installed in a potentially explosive atmosphere.
- To avoid condensation inside the condenser, remove
the refrigerant circuit caps only when positioning the
refrigerant connections.
- If the refrigerant connection is only made at the end of
the installation, ensure that the refrigerant circuit caps*
remain in place and tight throughout the installation
process.
* (Side of the hydraulic unit and side of the outdoor
unit).
- After any intervention on the refrigeration circuit and
before nal connection, replace the caps in order
to avoid any pollution from the refrigeration circuit
(sealing using tape is prohibited).

"This appliance uses refrigerant R410A.
Comply with the legislation for handling refrigerants.
3.1 Rules and precautions
"Connections must be made on the day of the
lling the installation with gas (see § 3.4, page
22).
• Tooling
- Pressure gauge kit (Manifold) with hoses exclusively
reserved for HFCs (Hydrouorocarbons).
- Vacuum gauge with isolation valves.
- Special HFC vacuum pump (use of a traditional
vacuum pump is authorised if and only if it is tted with
a non-return valve on the suction side).
- Flaring tool, pipe-cutter, Deburrer, Wrenches.
- Approved refrigerant detector (sensitivity 5g/year).
"The use of tools that have been in contact with
HCFCs (R22 for example) or CFCs is prohibited.
"The manufacturer shall not be held liable with
regard to the warranty if the above instructions
are not complied with.
• Flared connections
"Lubrication with mineral oil (for R12, R22) is
prohibited.
- Only lubricate with polyolester refrigeration oil (POE).
If POE oil is not available, t without lubrication.
Coat the ared surface with
PEO refrigerant oil.
Do not use mineral oil.
• Brazing on the refrigeration circuit (if necessary)
- Silver brazing (40% minimum recommended).
- Brazing with a dry nitrogen stream only.
• Important notes:
- After any intervention on the refrigeration circuit and
before nal connection, replace the caps in order to
avoid any pollution from the refrigeration circuit.
- To eliminate any lings in the pipes, use dry nitrogen
to avoid introducing any humidity that may adversely
a󰀨ect the appliance's operation. In general, take every
precaution to avoid humidity penetrating the appliance.
- Insulate the gas and liquid pipes to avoid condensation.
Use insulating sleeves that resist temperatures of
over 90°C. In addition, if the level of humidity around
the refrigerating pipes could exceed 70%, protect
the latter with insulating sleeves. Use an insulating
material thicker than 15mm if the humidity level
reaches 70~80%, and an insulating material thicker
than 20mm if the humidity level exceeds 80%. If the
recommended thicknesses are not complied with under
the conditions described above, condensation will form
on the surface of the insulation material. Finally, use
insulating sleeves with a thermal conductivity equal to
0.045 W/mK or less when the temperature is 20°C.
The insulation must be impermeable to prevent steam
from passing during the defrosting cycles (glass wool
is prohibited).
3.2 Shaping the refrigeration pipes
3.2.1 Bending
The refrigeration pipes must be shaped only on a
bending machine or with a bending spring in order to
avoid any risk of crushing or breakage.
"Warning!
• Remove the nearby insulation before bending the
tubes.
• Do not bend copper to an angle of more than 90°.
• Do not bend tubes more than 3 times at the same
point to prevent the pipe from splitting (hardening of
the metal).
3.2.2 Creating the arings
- Cut the pipe to an appropriate length with a pipe-cutter
without deforming it.
- Carefully deburr it, holding the pipe downwards to
avoid introducing lings into the pipe.
- Remove the are nut from the connector on the valve
to be connected and thread the tube through the nut.
- Flare it and leave the tube protruding from the aring
tool.
- After aring, check the condition of the face (L).
This must not show any scratches or traces of
fracturing. Also check the dimensions (B).
