Heat pump Alfea S
1 Description of the unit
1.1 Package
• 1 package : Outside unit.
• 1 package : hydraulic module and outdoor sensor.
1.2 Denitions
Split: The heat pump consists of two elements (an
outside unit for outside and a hydraulic module for
inside the dwelling).
Air/water: The surrounding air is the energy source. This
energy is transmitted to the water in the heating circuit
by the heat pump.
Inverter: the fan and compressor speeds are modulated
according to the heating requirements.
This technology enables you to save on energy and
operate on a single-phase power supply, whatever the
heat pump’s output, by avoiding heavy intensities on
start-up.
COP (coefcient of performance): this is the relationship
between the energy transmitted to the heating circuit
and electrical energy consumed.
Scope of application
This heat pump provides :
Heating in winter,
- Control of two heating circuits*,
- Production of domestic hot water*
(provided that combined with a DHW tank).
- Cooling* in summer (for oor heating-cooling system
or fan-convectors).
- Installation with boiler connection* as a supplementary
heating for the coldest days.
- Heating the swimming pool*.
* : These options require the use of additional kits
(see § "Optional equipment").

Heat pump Alfea S
1.6 Operating principle
The heat pump transmits the energy contained in the
surrounding air into the dwelling to be heated.
The heat pump consists of four main elements, in which
a refrigerant uid (R410A) circulates.
- In the evaporator (rep. 13, gure 7, page 11) :
The energy is taken from the surrounding air and is
transmitted to the refrigerant. Because it has a low
boiling point, it changes from the liquid state to the
vapour state, even in cold weather (down to -15 °C
outside temperature).
- In the compressor (rep. 10, gure 7 , page 11) :
The vaporised refrigerant brought to high pressure
and takes on more calories.
- In the condenser (rep. 15, gure 8, page 12) :
The energy in the refrigerant is transmitted to the
heating circuit. The refrigerant returns to liquid state.
- In the expansion valve (rep. 9, gure 7, page 11) :
The liqueed refrigerant is brought back to low pressure
and returns to its initial temperature and pressure.
The heat pump is equipped with a controller, which
controls the internal temperature based on the outside
temperature measurement and governed by the
temperature control.
The room thermostat (optional) provides a corrective
action for the temperature control.
The hydraulic module is equipped with an electric back-
ups system, which is triggered to provide additional heat
during the coldest periods.

Domestic hot water (DHW) operating principle
Two domestic hot water (DHW) temperatures can be
parametered: comfort temperature (line 1610 to 50 °C)
and reduced temperature (line 1612 to 25 °C).
Setting for reduced temperature can be useful to prevent
the DHW from switching on too often and for too long
during the day.
The production of domestic hot water (DHW) is triggered
when the temperature in the tank falls 7°C (setting from
line 5024) below the set temperature.
The heat pump produces the domestic hot water, which
is then supplemented, if required, by electrical backup
heating from the tank.
To ensure a DHW setting over 45°C, the electrical
backup heating or the boiler must be left on.
Depending on how the parameter (1620) is set, comfort
temperature can be reached 24h/day or only at night or
depending on the heat pump programme.
If the contract concluded with the energy provider
includes a subscription to day/night tariff, the electrical
backup is subordinate to the supplier’s power tariff and
the comfort temperature may only be reached at night.
If no particular contract is concluded, the comfort
temperature can be reached at any time, including
during the day.
The production of DHW 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 function to switch from "reduced" to "comfort" is
provided on the front of the user interface (see ref. 1,
gure 39, page 31 ).
This DHW boost enables the DHW to be heated to the
comfort temperature at any time during the day. The
boost function is cancelled automatically when the
demand for hot water has been met.
If the heating installation is equipped with a DHW
circulation pump, the pump’s operation during DHW
cycles can be parametered.
Anti-legionella cycles can be programmed.

2.1 Regulation installation
and maintenance conditions
The appliance must be installed and the maintained by an
approved professional in accordance with the prevailing
regulations and code of practice, in particular :
The legislation on the handling of refrigerants.
2.2 Unpacking and reservations
2.2.1 Receipt
Carefully check, in the carrier’s presence, the general
appearance of the appliances and check that the outside
unit is not laid on its side or back.
In the case of any dispute, state any appropriate
reservations to the carrier in writing within 48 hours and
send a copy of this letter to the After-Sales service.
2.2.2 Handling
The outside unit should not be laid on its side or back
during transport.
Laying the unit down during transport is likely to damage
the internal tubes and the compressor suspensions.
Any damage caused by transportation of the unit lying
down is not covered by the warranty.
If necessary the outside unit may be tilted only 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 upright
position.
2.2.3 Accessories provided
Accessories provided with the outside unit (gure 10).
Accessories provided with the hydraulic module
(gure 11).
2.3 Installation position
The choice of the position for installation is particularly
important insofar as any later movement is a delicate
operation requiring the intervention of a qualied
person.
Choose the site of the outside unit and the hydraulic
module after discussion with the customer.
Observe the maximum and minimum distances between
the hydraulic module and the outside unit (gure 13);
the guarantee of the performances and the system’s
service life depend on this.
2.4 Installation of the outside unit
2.4.1 Installation precautions
"The outside unit must only be installed outside
(outdoors). If a shelter is required, it must have
broad openings on the 4 walls and observe the
installation clearances (gure 12).
• Choose a site that is preferably sunny and sheltered
from strong cold predominant winds (mistral,
tramontana, etc…).
• The unit must be easily accessible for future installation
and maintenance work (gure 12).
• Ensure that it is possible to make the connections to
the hydraulic module easily.
• The outside unit is able to withstand bad weather but
avoid installing in a position where it is likely to be
exposed to signicant dirt or owing water (under a
defective gutter for example).

• Water may drain away from the outside unit when it
is operating. Do not install the appliance on a paved
terrace; choose a well-drained place (e.g. gravel
or sand). If the installation is in an area where the
temperature can be lower than 0°C for a long period,
check that the presence of ice does not present any
danger. A drainage pipe can also be connected to
outside unit (see para 2.4.3, page 16).
• Nothing should obstruct the air circulation through the
evaporator and from the fan (gure 12).
• Keep the outside unit away from heat sources and
inammable products.
• Make sure the appliance not disturb the surrounding
area or users (noise level, draught generated, low
temperature of the air being blown out, with the risk of
freezing plants in its path).
• The surface supporting the outside unit should :
- be permeable (soil, gravel, etc),
- support its weight easily,
- provide a solid xing and
- not transmit any vibration to the dwelling.
Anti-vibratory blocks are available, please consult your
retailer.
• The wall brackets is strongly discouraged due to
vibration.

2.4.2 Outside unit positioning
The outside unit must be raised at least 50 mm above
ground level. In areas prone to snow, this height should
be increased but should not exceed 1,5 m (gure 14).
- Fasten the outside unit by means of screws and
rubber tightening or toothed lock washers to avoid
their coming loose.
2.4.3 Condensate drain hose
(see gure 14).
If the use of a discharge pipe is imperative :
- Use the elbow provided (C) to connect a 16mm
diameter hose for draining away the condensate.
- Use the stopper or stoppers provided (B) to block the
opening of the condensate tank.
Allow for the condensate to ow away under the force of
gravity (waste water, rain water, gravel bed).
"If the installation is made in an area where
the temperature can be lower than 0°C for
a long period, provide the drain pipe with a
trace resistance to avoid it icing up. The trace
resistance must heat not only the pipe but
also the bottom of the appliance’s condensate
collection tank.

2.5 Installing the hydraulic module
2.5.1 Installation precautions
• The room in which the appliance operates must comply
with the prevailing regulations.
• To facilitate maintenance and to allow access to the
various components, we recommend that you provide
sufcient space all around the hydraulic module
(gure 15).
• Be careful not to bring inammable gas near to the
heat pump during its installation, in particular when it
requires brazing.
The appliances are not reproof and should not therefore
be installed in a potentially explosive atmosphere.
2.5.2 Positioning the hydraulic module
-1, 2, 3 : Remove the front panel
(2 screws A, gure 16).
-4, 5 : Remove the sides
(4 screws B, gure 17).
- Fix the support solidly (3 screws and plugs) to a at,
hard-wearing wall (not a light partition) ensuring that it
is correctly levelled.
- Hook the appliance onto its support.
- Ret the sides.
- Ret the front facing.

2.6 Refrigeration connections
"This appliance uses refrigerant R410A.
Comply with the legislation for handling refrigeration
uids.
2.6.1 Rules and precautions
• After every intervention on the refrigeration circuit and
before nal connection, take care to replace the plugs
in order to avoid any pollution from the refrigeration
circuit.
• Tools
- Set of manometers with hoses exclusively reserved
for HFCs (Hydrouorocarbons).
- Vacuum pump specially for HFCs.
- Provision on using tools that have been in contact with
HCFCs (R22 for example) or CFCs.
- Use of a traditional vacuum pump is authorized if, and
only if, it is tted with a non-return valve on the suction
side.
The manufacturer declines any liability with regard to the
guarantee if the above instructions are not observed.
• Flared connections
"Lubrication with mineral oil (for R12, R22) is
forbidden.
- Only lubricate with polyolester refrigeration oil (POE).
If POE is not available, t without lubrication.
• Brazing on the refrigeration circuit (if necessary)
- Silver brazing (40% minimum recommended).
- Brazing only under dry nitrogen internal ux.
• To eliminate any lings in the pipes, use dry nitrogen
to avoid introducing any humidity that may adversely
affect the appliances operation. In general, take every
precaution to avoid humidity penetrating into the
appliance.
• Use pipe insulators resistant to temperatures over
120°C. In addition if the humidity level in areas where
the refrigeration pipes are installed is expected to
exceed 70%, protect the pipes with pipe insulators.
Use an insulating material thicker than 15mm if the
humidity level is 70~80%, and an insulating material
thicker than 20mm if the humidity exceeds 80%. If the
recommended thicknesses are not observed under the
conditions described above, condensation will form on
the surface of the insulation material. Lastly, take care
to use pipe insulators whose thermal conductivity is
0.045 W/mK or less when the temperature is 20°C. The
insulation must be impermeable to resist the passage
of steam during the defrosting cycles (breglass wool
is prohibited).
2.6.2 Refrigeration connections
The outside unit must be connected to the hydraulic
module with copper pipes and connections (refrigeration
quality), insulated separately.
Comply with the pipe diameters and the permitted pipe
lengths (gure 13).
The minimum length of the refrigeration connections
is 5m for correct operation (except model S5 and S6,
see gure 13).
The appliance will be excluded from guarantee if it is
used with refrigeration connections less than 5m long
(models S8, S10, S13, S16).
Manipulate the pipes and take them through walls with
protective plugs in place.
If the distance between the outside unit and the hydraulic
module exceeds the length of the maximum conduits
indicated in the table, an additional charge of R410A
must be loaded.
The quantity of R410A added must be adapted to the
length of the refrigeration circuit in order to the heat
pump’s performance without damaging the compressor
(gure 23).
2.6.3 Creating the arings
- Cut the pipe to an appropriate length with a pipe-cutter
without deforming it.
- Carefully deburr it, holding the pipe towards the bottom
to avoid introducing lings into the pipe.
- Remove the ared connection nut situated on the valve
to be connected and slip the pipe into the nut.
- Proceed to are, letting the pipe overow the aring
tool.
- After aring, check the condition of the working radius
(L). This must not show any scratch or trace of any
fracturing. Also check the dimension (B).

2.6.4 Shaping the refrigeration pipes
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 breaking them.
"Warning
• Remove the insulation material locally to bend the
pipes.
• Do not bend the copper to any angle over 90°.
• Never bend pipes more than 3 times in the same
position otherwise traces of fracturing may appear
(from strain-hardening the metal).
2.6.5 Connecting the ared connections
"The small pipe must always be connected before
the large one.
"Take particular care positioning the tube opposite
its connector so as not to risk damaging the
threads. A carefully aligned connector can be
tted easily by hand without much force being
required.
"The refrigeration circuit is very sensitive to dust
and humidity: check that the area around the
connection is clean and dry before removing the
plugs protecting the refrigeration connectors.
