1 Description of the unit
1.1 Package
•
1 package: Outside unit
•
1 package: hydraulic module and outdoor sensor
1.2 Definitions
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
(coefficient of performance): this is the
relationship between the energy transmitted to the
heating circuit and electrical energy consumed.

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 fluid (R410A) circulates.
-
In the evaporator (rep. 13, fig 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, fig 7, page 11): The
vaporised refrigerant brought to high pressure and
takes on more calories.
-
In the condenser (rep. 15, fig 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, fig 7, page 11): The
liquefied 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.
Regulation functions
- The heating circuit’s initial temperature is controlled
by the temperature control.
- The power of the outside unit is modulated
according to initial heating temperature via the
“inverter” compressor.
-
Control of the electric back-up heating.
-
The daily timer program enables you to define the
periods for comfortable or reduced ambient
temperature.
-
Summer/winter mode switchover is automatic.
-
Control of the supplementary boiler* (the electric
back-ups are deactivated).
-
The room thermostat* (optional) provides a
corrective action for the temperature control
-
Control of a second heating circuit*.
-
Domestic hot water: Heating time programme,
control of the operation of the DHW circulation
pump.
-
Control of swimming pool heating*.
Protection functions
-
Anti-legionella cycle for domestic hot water.
* If the heat pump is equipped with optional
equipment and the associated kits.
Domestic hot water (DHW) operating principle
Two domestic hot water (DHW) temperatures can be
parametered: comfort temperature (line 1610 to 60
°C) and reduced temperature (line 1612 to 40 °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.
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 DHW “ boost” function is available on the front of
the user interface (see ref. 1, fig. 39, p 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 Installation
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
(figure 10).
Accessories provided with the hydraulic module
(figure 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
qualified 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
(Figure 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
F
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 (fig. 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 (fig. 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 significant dirt or flowing water (under
a defective gutter for example).
•
Water may drain away from the outside unit when it
is operating. You can let this defrosted water run off
over a gravel or sand bed or a concrete slab with a
diamond point and a sinkhole in the ground. 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 § 2.4.3, page 16).
•
Nothing should obstruct the air circulation through
the evaporator and from the fan (fig. 12).
•
Keep the outside unit away from heat sources and
inflammable 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 receiving the outside unit must be able
generally to support its weight; provide a solid fixing
and do not transmit any vibration to the dwelling.
Anti-vibratory blocks are available, please consult
your retailer (Atlantic).
2.4.2
Outside unit positioning
The outside unit must be raised at least 50mm above
the ground. In snowy areas, this height must be
increased (figure 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 figure 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)toblockthe
opening of the condensate tank.
Allow for the condensate to flow away under the
force of gravity (waste water, rain water, gravel bed).
F
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.

2.6 Refrigeration connections
F
This appliance uses refrigerant R410A.
Comply with the legislation for handling refrigeration
fluids.
2.6.1
Rules and precautions
•
After every intervention on the refrigeration circuit
and before final 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 (Hydrofluorocarbons).
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 fitted 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
F
Lubrication with mineral oil (for R12, R22) is
forbidden.
- Only lubricate with polyolester refrigeration oil
(POE). If POE is not available, fit without
lubrication.
•
Brazing on the refrigeration circuit (if
necessary)
- Silver brazing (40% minimum recommended).
-
Brazing only under dry nitrogen internal flux.
•
To eliminate any filings 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.
Proceed to insulate the gas and liquid pipes to avoid
any condensation.
Use insulating sleeves resistant to temperatures
over 120°C. In addition if the humidity level in the
areas where the refrigeration pipes pass risks
exceeding 70%, protect the pipes with insulating
sleeves. Use a sleeve thicker than 15mm if the
humidity reaches 80%, and a sleeve 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 insulating sleeves 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 (fibreglass 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 (figure 13).
The minimum length of the refrigeration
connections is 5m for correct operation.
The appliance will be excluded from guarantee if it is
used with refrigeration connections less than 5m
long.
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 (figure 23).
2.6.3
Creating the flarings
-
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 filings into the pipe.
-
Remove the flared connection nut situated on the
valve to be connected and slip the pipe into the nut.
-
Proceed to flare, letting the pipe overflow the flaring
tool.
-
After flaring, 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.
F
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 flared connections
F
The small pipe must always be connected
before the large one.
F
Take particular care positioning the tube
opposite its connector so as not to risk
damaging the threads. A carefully aligned
connector can be fitted easily by hand
without much force being required.
F
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.

2.7 Filling the installation with gas
F
This operation is reserved for installers
familiar with the legislation for handling
refrigeration fluids.
F
Creating a vacuum with a vacuum pump is
essential.
F
Never use equipment used beforehand with
any refrigerant other than a HFC.
2.7.1
Creating a vacuum and filling the
refrigeration connections with gas
(see figure 22).
-
Remove the protective plugs (B) from the charging
hole (Schrader) in the gas valve (large diameter).
-
Connect the blue hose (on the side with a valve
pusher in good condition) from the set of
manometers (manifold).
-
Connect the yellow hose to a vacuum pump and
open the blue valve on the set of manometers.
-
Create a vacuum until the residual pressure in the
circuit falls below 0.01 bar.
-
Let the pump continue to operate for another 15
minutes after reaching the vacuum.
- Close the blue valve on the set of manometers and
then stop the vacuum pump without
disconnecting any of the hoses in place.
- Wait 10 minutes. If the pressure rises during this
10-minute period, there is a leak in the circuit. Trace
it and repair it: then start again.
When the pressure has remained stable for 10
minutes after the vacuum pump stops, the circuit is
considered to be gas-tight.
- Remove the access plugs (A) from the valve
controls.
F
If an additional charge is requires, add the
additional charge before filling the hydraulic
module with gas. Please refer to the section
(“Additional charge”, page 22).
-
First of all fully open the small valve and then the
large one using a hex key (counterclockwise
direction) without forcing excessively against the
stop.
-
Remove the blue hose rapidly.
-
Refit the 2 plugs and tighten them to the
recommended tightening torque (see figure 21).
The outside unit does not contain any additional
refrigerant, enabling the installation to be purged.
Flushing is strictly forbidden.
2.7.2
Sealing test
Once the refrigeration circuit has been gassed as
described above, check that all the refrigeration
connectors are gas-tight:
6 connectors for models 050 and 065, 5 connectors
for model 080 and 4 connectors for models 095, 128
and 155.
The sealing test must be performed with an
approved gas detector.
If the flarings have been made correctly, there should
be no leaks.
If there is a leak, make the connection again.

Additional charge
The charge in the outside units corresponds to the
maximum distances between the outside unit and
the hydraulic module defined in Figure 13.
If the distances are greater, an additional charge of
R410A is required.
The additional charge depends on the distance
between the outside unit and the hydraulic module
for each type of appliance (Fig. 23)
The additional charge of R410A must necessarily be
made by an approved refrigeration engineer.
•
Example for a heat pump model 155
An outside unit 32m away from the hydraulic module
will require an additional charge of:
Additional charge = (32 - 20) x 40 = 480 g
The charge must be introduced after creating the
vacuum and before the hydraulic module is filled with
gas, as follows:
-
Disconnect the vacuum pump (yellow hose) and
connect a bottle of R410A instead in the fluid
extraction position.
-
Open the bottle’s valve.
-
Bleed the yellow hose by loosening it slightly on the
manifold side.
-
Place the bottle on scales with a minimum accuracy
of 10g. Note the weight.
-
Carefully open the blue valve slightly and check the
valueshownonthescales.
-
As soon as the value displayed has dropped by the
value for the calculated additional charge, close the
bottle and disconnect it.
-
Then rapidly disconnect the hose connected to the
appliance.
-
Proceed to fill the hydraulic module with gas.
F
Warning
•
Only use R410A!
•
Only use tools suitable for R410A (set of
manometers).
•
Always charge in the fluid phase.
•
Never exceed the length or the maximum difference
in level.

2.8 Connecting
the heating circuit hydraulically
2.8.1 General
The connection must comply with good trade
practice according to local building regulations.
The heating circulating pump is built into the
hydraulic module.
Connect the central heating pipes to the hydraulic
module, complying with the direction of circulation.
The diameter of the pipes between the hydraulic
module and the heating collector must be at least 1
inch (24x36mm).
Calculate the diameter of the pipes according to the
flow rates and the lengths of the hydraulic systems.
Use union connectors to facilitate removing the
hydraulic module.
Preferentially use connection hoses to avoid
transmitting noise and vibrations to the building.
Connect the drains from the drain valve and the
safety valve to the main sewer system.
Reminder: Seal everything when fitting in
accordance with prevailing trade practice for
plumbing work:
-
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.
If you are using a glycol/water mix, provide for an
annual check on the quantity of glycol.
In certain installations, the presence of different
metals can cause corrosion problems; the formation
of metal particles and sludge in the hydraulic circuit
is then seen.
In this case, it is advisable to use a corrosion inhibitor
in the proportions indicated by its manufacturer.
It is also necessary to ensure that the treated water
does not become aggressive.
2.8.2
Rinsing out the installation
Before connecting the hydraulic module to the
installation, 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.).
In the case of an old installation, provide a sufficiently
large decanting pot with a drain on the return from
the boiler and at the lowest point in the system in
order to collect and remove the impurities.
Add an alkaline product to the water and a
dispersant.
Rinse the installation several times before filling it
definitively.
2.8.3
Filling and purging the installation
Check the pipe fixings, the tightness of the
connectors and the stability of the hydraulic module.
Check the direction in which the water is circulating
and that all the valves open.
Proceed to fill the installation.
Do not operate the circulating pump while filling.
Open all the drain valves in the installation and the
bleed valve for the hydraulic module to remove the
air contained in the conduits.
Close the drain and bleed valves and add water until
the pressure in the hydraulic circuit reaches 1.5 bar.
If the pressure is lower than 0,5 bar, the Heat Pump
stops and posts error 369.
Check that the hydraulic circuit has been purged
correctly.
Check that there are no leaks and that the circulating
pumps are not seized (if need be, release them).
After the “Start-up” stage (see p. 30), once the
machine has started, purge the hydraulic module
again (2 litres of water).

2.10 Outdoor sensor
The outdoor sensor is required for the heat pump to
operate correctly.
Consult the fitting instructions on the sensor’s
packaging.
Place the sensor on the coldest part, generally the
northern or north-eastern side.
In any case, it must not be exposed to the morning
sun.
It must be installed so as to be easily accessible but
at least 2.5m from the floor.
It is essential that it avoid any sources of heat such
as flues, the upper parts of doors and windows,
proximity to extraction vents, the underneath of
balconies and under-eave areas which would isolate
the sensor from variations in the outside air
temperature.
-
Connect the outdoor sensor to the M and B9
terminals on the heat pump control board (fig. 38,
p. 29).
2.11 Room thermostat and/or remote
control
The room thermostat (remote control) is optional.
Consult the fitting instructions on the sensor’s
packaging.
The sensor must be installed in the living room area
on a very uncluttered wall, 1.5m above the floor.
Avoid direct sources of heat (chimney/flue,
television, cooking hobs), draughty areas
(ventilation, door, etc.).
Air leaks in the seals in the constructions are often
translated into cold air blowing through the electrical
conduits. Lag the electrical conduits if there is a cold
draught on the back of the IR sensor.

Start-up
-
Close the installation’s main circuit breaker.
On first commissioning (or in winter), in order to allow
the compressor to pre-heat, engage the installation’s
main circuit breaker (power supply to the outside
unit) some hours before starting up the tests.
-
Engage the heat pump’s ON/OFF button.
When the power is switched on and every time that
the ON/OFF button is switched off and then switched
on again, the outside unit will take approximately 4
minutes to start up, even if the setting is requesting
heating.
- Make all the specific adjustments to the setting
(configuring the installation).
- Press the key
- Hold down the key for 3s and select the level of
access used with the aid of the knob .
-
Confirm with the key
-
Parameter the heat pump’s setting
-
Consult the settings’ list (page 34).
On commissioning (or the case of error 10), the
electrical backup heaters are liable to start up even if
the outside temperature at the time is above the
heaters’ trigger temperature.
The regulating system uses an average initial
outside temperature of 0°C and requires some time
to update this temperature.
To mitigate this situation, the sensor must be
connected correctly. Re-initialise parameter 8703
(implementation level, consumer diagnostic menu).

3.3 Temperature control
The heat pump’s operation is subject to the
temperature control.
The set temperature for the water in the heating
circuit is adjusted according to the outside
temperature
The temperature control may be chosen
automatically by the machine (self-adaptation) or set
manually by the installer (Parameters 720, 721 and
726).
If there are thermostatic valves on the installation,
these must be fully open or adjusted for higher than
the normal set temperature.
3.4 Manual adjustment
During installation, the temperature control must be
parametered according to the heat emitters and the
dwelling’s insulation.
The temperature control’ curves (Fig. 41) refer to an
ambient setting of 20°C.
The slope of the temperature control (parameter
720) determines the impact of the variations in the
outside temperature on the initial heating
temperature variations.
The higher the slope, the more a slight reduction in
the outside temperature causes a significant
increase in the initial water temperature in the
heating circuit.
The off-set in the temperature control (parameter
721) alters the initial temperature of all the curves,
without altering the slope (Fig. 42).
Thecorrectiveactionsinthecaseofany
inconvenience are detailed in the table (Figure 43).
3.5 Self-adaptation
When this function is active (parameter 726), the
temperature control are automatically adjusted; it is
therefore futile to alter the slope or the off-set in the
temperature control (parameters 720 and 721).
When this function is first activated, the end user
may experience some inconvenience for a few days.
This period of no more than a week is required by the
regulator to determine the slope and off-set in the
temperature control.
We advise against changing the temperature
settings during this period.
The following instructions must be observed for the
self-adaptation system to operate correctly:
-
A room thermostat must be connected.
-
The influence of the ambient temperature"
(parameter 750) must be set between 1 and 100%.
-
Depending on the installation, the room thermostat
may have a greater or lesser influence on the
temperature control.
-
The room in which the room thermostat is installed
must not contain any thermostatic valves. If this is
the case, the valves must be open fully.
