• LIBERTY300 Solar is composed of a hot water tank, a solar
heat exchanger, components of the refrigerating circuit, the
air circuit and of the water circuit, as well as all the control,
settings and monitoring panels designed for automatic
functioning.
• the solar heat exchanger is located in the bottom part of
the tank. This heat exchanger must be connected to one or
more solar collector (not included). A pump (not included) is
necessary to make the uid circulate in the solar circuit.
• Solar components must be installed according to specications
and instructions of the manufacturer.
• LIBERTY300 Solar is equipped with an air to water heat
pump, used as back up. When solar energy is no more available,
the heat pump starts and heats the water to the temperature
setting with up to 3 times less energy than electric heater.
• An additional electric heater (1500W) located in the middle
of the tank will be used in case of air temperature out of the
operating range of the heat pump, and when solar is not
running.
LIBERTY300 Solar has dierent temperature sensors in the
tank and in the solar collector. When the temperature dierence
between the collector and the tank increases, the pump starts
and heat recovery from the sun energy begins.
When the temperature gap between collector and water is too
low, the pump stops, avoiding energy losses.
• LIBERTY300 Solar has a single controller for managing the
dierent energy sources: solar and heat pump. The heat pump
starts when the temperature setting is not reached and when
solar energy is not available.
• A drop in the aspiration temperature provokes a diminishing
in the performance of the heat pump and a prolonging of the
heating time for domestic hot water (see Fig.28 & 29 in the
appendix). A sensor measures the temperature of the aspired air
directly in the upstream from the evaporator of the heat pump.
When this temperature descends below the limit of -7°C, the
water is no longer heated by the heat pump but by the electrical
backup.
• The exible isolated air sheathing (ND160, max total lenght
10m with exible duct or ND160 max total lenght 20m with
rigid ducts) can be connected to the connection anges on
LIBERTY300 Solar. To insure an ecient functioning of the
heat pump, it is of general convenience to avoid all mixture
between input and output air. One of the possible solutions is
to use an elbow joint at the opening of the output.
To be considered when choosing the nal placement:
• D.W.H.P must not be installed outdoor
• D.W.H.P must be installed in a room outdoor from
frost. Also, the temperature of the air taken in must
range between -7°C and 35°C. When the temperature
is below -7°C or above 35°C, the water is no longer
heated by the heat pump, but by the electrical backup.
• inlate air must be clear of any pollution, and dust.
• The air taken in must not originate from a heated room.
• The device must not be placed in a room which risks
explosion due to gases, vapours or dust and must not
intake air from rooms with the same risks.
• For a higher sound comfort avoid installation near
bedrooms.

3.3 - Installation with air duct
3.4 - Air duct sizing
3.5 - Plumbing connections
3.2.2 - Positioning
• The oor must be able to support the weight of the device
(weight of D.W.H.P when full = approx. 440kg)
• Position D.W.H.P and adjust the stands in such a way that it is
level. A slight inclination to the right of the device (1° max.) is
acceptable.
Installation in a room smaller
than 20m² requires ducts to
take air in and to blown air out
View from above
In case air ducting, the speed fan must be
changed (see § «Change of fan speed»
Maximum length of ducts + elbow (1m) =
Flexible duct : 10m
Rigid duct : 20m
Outdoor air Heated or
unheated
room
0,5 m mini
2 m mini
The connection of D.W.H.P must be done using insulated
air ducts of a nominal diameter of 160mm. The piping can be
connected either on the intake side, the blowing side or both.
Example :
(1) : Elbow 70°C – ø160 (Réf. 710133)
(2) : Insulated flexible hose

(Réf. 710136)
(1)(2)
• It is mandatory to install a new pressure-relief valve (not
included) set to 7 bars on the domestic cold water supply of the
device. Membrane type valve are recommended.
This pressure-relief valve must conform to the domestic
standard.
• The pressure-relief valve must be installed as close as possible to
the cold water inlet of the device and the passage of water
must never be hindered by any accessory (valve, pressure
controller, etc...)
• The drain outlet of the pressure-relief valve must be sized
following the requirements of construction standard and must
never be blocked. It must be connected by use of a funnel,
allowing a minimum 20mm open space, to a vertical draining
pipe of a diameter equal to the piping connection of the device.
• The drain outlet of the pressure-relief valve must be installed in
a frost-free place and pointing downward.
• If the pressure of the domestic cold water supply is higher than
5 bars, install a pressure reducer above the pressure-relief valve
at the beginning of the installation (a pressure of 4 to 5 bars is
recommended).
• It is advised to install a shut-o valve above the pressure-relief
valve.
• In cases of installations equipped with
- piping of a small diameter
- ceramic plate valves
it is necessary to install, as close as possible to the shut-o
valves, a domestic expansion vessel adapted to the installation.
• For the domestic hot water circuit, use the following materials:
- copper
- galvanised steel
- brass
Depending on materials used in the hot water circuit,
incompatibilities could result in damage due to corrosion.

- INSTALLATION GUIDE 10.13.19.GB.03 - 5
NB: • Domestic hot water recycling: in
order to save energy, it is recommended
not to use domestic hot water recycling.
When a recycling line is attached to the
hot water distribution systen, foresee the
possibility of a shut-o mechanism (valve
or faucet) in order to limit useless energy
loss. The connection of the recycling line is
carried out in funtion of need (with a timing command).
• Condensate run-o (see section “Condensate line connections”)

DRAINING OF LIBERTY300 Solar
The drain valve must be installed in the lower position of inlet
water circuit
Draining is operated as follow :
- Connect the drain valve to the house drain circuit (10)
- Shut o the water feed valve (1)
- Open valves in upper position of the domestic hot
water circuit to let air enter
- Drain the tank by opening the drain valve (10)
In consequence, the connection of the device to the
copper piping of the domestic hot water should
ALWAYS be carried out via a cast iron tting, or
steel, or with the help of dielectric connections (not
included) which will help to avoid any iron/copper
galvanic bridge.
• Rinse the supply line piping before attaching it to the domestic
installation of the device in order to avoid the introduction of
any particles, metallic or other.
• Respect the current standard in the country of use, notably those
that concern domestic and pressure safety conditions.
• The maximum temperature of the domestic hot water at
delivering points should never surpass 50°C for the toilet and
60°C for other uses. Install thermostatic mixing valves adequate
enough to avoid any burn risks.
• In regions where the water contains high levels of limestone
(TH > 20°F), it is recommended to treat water with a softener.
Softened water should conform to the criteria dened by the
country’s norms.
• In all cases, softened or not, the latter should conform to the
country’s hot water additional clause norms concerning:
- chloride levels
- resistivity (between 2200 and 4500 ohm/cm)
- 12°F < TH < 30°F
- …
The warranty does not apply if these
points are neglected or if the water quality
did not allow the correct treatment in the legal
framework.
The water cycling loop is not
recommanded. This is source of energy
losses and lack of hot water.The cycling
loop must be insulated and the circulating
pump must be controled by a timer or any other
system avoiding permanent running.
3.6 - Condensate line connections
3.7 - Solar conductor connections
• the condensate tube must be connected directly to the sewer. It
must run-o into open air before entering in a siphon. It should
lead to the open air in a siphon to be imperatively added and
lled with water,
• do not attach it to a boot,
• no not bend the tube,
• keep the tube vertical and open toward the bottom.
LIBERTY300 Solar is delivered with temperature sensors at
inlet and outlet of the heat exchanger (size M1/2”). The hydraulic
circuit of the solar collector has to be connected to these inlet and
outlet ports.
Any component needed to complete the hydraulic circuit must
be installed according to the mounting instructions of the solar
equipment manufacturer.
- Heat exchanger inlet connector = high position, short cable, red
ring
- Heat exchanger outlet connector = low position, long cable,
blue ring

Temperature in the solar collector is measured by the means of a
PT1000 sensor, included in the LIBERTY300 Solar packaging.
This temperature sensor must be located in the solar collector
according to the collector manufacturer instructions. This
temperature sensor must be plugged to input 5 («entrée 5») of
the electric board of LIBERTY300 Solar (see gure below).
For the connection from collector sensor to the tank controler, use
an extension cable with 2 wires, minimum section 0.5mm².
The solar pump (not included) must be plugged to the electric board
of LIBERTY300 Solar as follow:
For pump consumming up to 200W, connection can be made
directly at connector «Entrée 2» («Solar pump» on the gure below)
with a 3G 0,75mm² cable.
Bigger pump have to be supplied through an intermediary relay.
Relay coil should be connected to «Entrée 2» («Solar pump»).
The device is polarised, respect the
polarity:
• Brown wire = 230V phase
• Blue wire = Neutral
• Green/Yellow wire = Ground
Grounding is mandatory In cases of high domestic hot water
uses and when the device operates
with a low air temperature, the heating time
is longer than 8h (See Fig.7-4 & 7-5 in the
appendix). It is recommended to adapt the
timing programme according to use.
For solar inputs, no other sensor can be
plugged except PT1000 type

3.8.1 - Solartemperaturesensor andsolar pump
3.8.2 - Peak time / o peak time operation
It is possible to program an operating time range (for example
during 8 o-peak hours). This programming can be easily carried
out with the control panel (see section programming).
To forbid operation of electric back up during peak time, an
external control can be connected.
• Open contact = electric backup o
• Closed contact = electric backup autorized
the dry contact does not control the heat pump operation, but
only the electric backup
NB: • LIBERTY300 Solar can also operate using
an internal timing program (see section“Time
programming”).
• Pass a 0.75 mm² 2 wire cable with metal tips through an available
cable gland at the back of the device and bring the extremity of
the cable to the electronic card. The other end of the cable is to
be connected to the electrical service provider’s contact.
• Remove the black protection cover of the electronic card.
• Insert the 2 wire cable via a grommet of the electronic card.
• Attach the 2 wire cable on the entry of the electronic card
marked “Entrée 3”after having removed the existing red bridge.

3.8.3 - Ventilation control
D.W.H.P can be used to permanently ventilate a room .This ventilation
can be used to renew the air. In this case, the connection of a humidity
sensor (entry 2) allows to activate the operation of the ventilator in
function to the ambiant humidity. In all cases, the ventilator always
operates with the heat pump.
• swith open = the ventilator does not operate
• switch closed = the ventilator operates
Set the regulator to mode“Ventilation with external control”
(PAR05 = 3)
4 - SET UP AND USE
LIBERTY300 Solar functions mainly with sun heat recovery
through the solar collector. The water tank is heated up to 65°C as
long as solar collector is sun exposed.
When solar energy is not available, the tank is heated via the air
to water heat pump. The temperature setting is dened by the
end user (initial setting 50°C). Heat pump operates as long as
the temperature of the air taken in remains with the authorized
range of -7°C to +35°C. Outside of this range, the electrical backup
ensures the heating of domestic hot water.
The temperature of domestic hot water supplied by the heat
pump is adjustable to 60°C. In function of the volume of
consumed water and to ensure savings, it is recommended
to limit the temperature of domestic hot water to a lower
temperature.
Occasionally, a defrosting can occur. If the temperature of the air
taken in is sucient, the defrosting is carried out by ventilation
only. If the air temperature of too low, the defrosting is carried out
with the help of the compressor to melt the frost.
The ventilation speed is adjustable in function of the temperature
of the air taken in. The variation of ventilation speed is automatic
for a lowered sound level and the optimisation of the coecient
of performance.
LIBERTY300 Solar possesses a ventilation function (parameter
PAR.05). Along with its normal function associated with the heat
pump, the ventilator can be permanently activated or activated
by external command to ventilate a room (see section“PAR.05 –
Ventilation mode”).
In case of high domestic hot water consumption, LIBERTY300
Solar possesses a comfort function that increases the heating
capacity when there remains only 1/3 of the volume of the tank
above 38°C (see section“PAR.10 – Minimum temperature”°.
In instances where there is a need for high amounts of domestic
hot water, LIBERTY300 Solar possesses a “boost” function
(activated by the user) which ensures the quick heating of water
to the desired temperature (50°C for example) with the help of the
heat pump and the electrical backup. This function is deactivated
as soon as the desired temperature is achieved (e.g. 50°C).
Periodically check for alarms (in case of alarm, see section “Error
message”).

Parameter 04 allows the set the interval between two anti-
legionellosis cycles.
During the anti-legionellosis cycle the temperature of the water is
raised to 60°C by the heat pump.
If the default for domestic hot water is already set to 60°C (see
section “Desired water temperature settings”) there will be no
anti-legionellosis cycle since it is already permanent.
• Press the dial to access the anti-legionellosis
cycle settings
• Default setting : 0
No anti-legionellosis cycle, except when
returning from vacations and after frost
periods of more than 3 days.
• Setting of a periodic cycle:
• Turn the dial to change the number of days.
• Press the dial to accept the changes.
Example: PAR.04 = 8, the anti-legionellosis cycles happens every 8
days at 22:00.

The start-up setting of the electrical backup can be shifted (either
in + or in -) according to the comfort setting chose by the user
(e.g. 55°C)
If the temperature of the air is out of functioning range (<-7°C
or >+35°C), the heat pump cannot function, it is the electrical
backup that automatically takes control.
Since this backup is more energy consuming than the heat pump,
and to achieve savings, a lower domestic hot water temperature
can be dened for the latter (e.g.: PAR.09 = -5°C, the setting
therefore becomes 55°C – 5°C = 50°C)
However, since the electrical backup only heats the upper part
of the tank, if the consumption of hot water is high it could be
necessary to dene a higher temperature for the electrical backup
(e.g. : PAR.09 = +10°C, the setting therefore becomes 55+C + 10°C
= 60°C)
The temperature of the automated electrical backup cannot, in
any case, surpass 65°C.

It is possible to authorise the operation of the electrical backup

temperature to 43°C and will stop and the heat pump will nish

5 - MAINTENANCE AND
REPAIR
To maintain performance, it is recommended to have the device
inspected by a qualied person every two years.
NB
During maintenance or the shutting down of
D.W.H.P, follow the environmental protection rules
with respect to recovery, recycling and disposal of
consumable parts and components.
• All intervention on the refrigerating
circuit must be done by a qualied person
with a category 1 certicate of aptitude.
•The release of the refrigerant into the
atmosphere is not permitted, the refrigerant
recovery must be done before any intervention
on the refrigeration circuit.
•Turn D.W.H.P o before opening it.
•Wait for the complete stop of the ventilator
before any intervention.
• Make the anode inspection every year
• Do not spring water on electical parts
The inspection of the water circuit is limited to the inspection of
the lters and of eventual leaks. Clean or replace the dirty lters.
Check that the condensate draining is operating correctly:
- Remove the upper cover (see section “Peak time / o-
peak time functioning”).
- Verify that the evacuation orice is not blocked.
- Clean the condensate recovery container where deposits
brought in by the air can accumulate.
- Clean the condensate tube.
The pressure limiter has to be checked and cleaned, régularly to
prevent any disfunctionning.
Check the leak tighteness on every tting, ange and hydraulic
connections.
5.1 - Water circuit / condensate draining
5.2 - Air intake circuit
Maintenance work is limited to the cleaning of the evaporator (at
least once a year according to the cleanliness of the air taken in).
If the lters are used, check regularly that they are not dirty. Clean
them if necessary.
NB
Sharp edged ns : wound risk. Be careful not to
deform or damage the ns.
Counters menu gives information about the number of start/stop
cycle of the heat pump, the electric heater and the solar pump.

5.3 - Anti-corrosion anode
5.4 - Troubleshooting
5.5 - N.T.C. Sensors characteristics
The anti-corrosion anode is installed in the hot water tank and
must be regularly electrically tested as well as a minimum of every
years after the activation of D.W.H.P. Replace it if necessary.
- Drain water out of the tank
- Unscrew the anode from the tank
- Check the anode diameter at the thinest point :
diameter must be higher than 15mm
- Change the anode if its diameter is less than 15mm
(the initial diameter being 33mm)
An anti-corrosion anode in bad
working condition shortens the length
of operation of the device and nullies the
warranty.
• The solar pump does not start while sun has been
shining for a moment
Check that:
• Temperature setting for hot water has been reached and
therefore no solar load is requested.
• Protection against overheating is triggered:
- Check that temperature in collectors “SOLAR COL.”is
over 70°C. Operation will be automatically authorised
again once temperature of collector is back under 70°C.
• Solar pump operates normally :
- Start a manual operation of the pump (“RUN SOLAR” in
installer menu). This manual operation is not possible
when system is under overheating protection.
• Solar pump operates normally :
NB
If protection against overheating occurs too often:
• Check that solar pump is set on a sucient speed
• Check that system is not oversized (too large area
of collectors, too low water consumption)
• The heat pump does not work
Verify that :
• Temperature setting is higher than the water temperature in
the tank.
• The device has the proper power supply and that the polarity
is respected:
Phase on brown wire
Neutral on blue wire
Ground on green / yellow wire
• The light is on.
• The device is not in vacation mode ( symbol)
• The temperature of the air taken in is lower than -7°C or
higher than +35°C.
• An external manipulation or a programmed hourly range is
not preventing the operation ( symbol,“econo-mode”lit).
• An error is displayed on the screen (see section on error
codes).
• Lack of Hot water
Verify that:
• Water consumption is higher than the tank capacity.
• The authorized operating range is not too short (12 hours
minimum if connected with duct).
• The programmed water temperature is not too low.
• Condensates do no run-o (presence of water
under the device)
Verify that:
• The condensate evacuation system is not dirty of blocked.
Clean if necessary:
Remove the cover (see section “Peak time / o-peak time
functioning”).
Check for blockage.
• The tube is not bent or not moking a loop straight down.
• The tube gives o into open space.
• The electrical backup does not work
Verify that:
• An external manipulation or an hourly programming is not
preventing the operation ( symbol,“econo-mode”lit).
• The security limiter thermostat of the electrical backup has
not been set o following an overheating (>85°C). In this
case, rearm it (see section“Security devices”).
• Before rearming : verify that :
