INSTALLATION

Air to Water Heat Pump Split single service

For professionals. To be kept by the user for future reference

EN

■ Installation and maintenance rules

The appliance must be installed and maintained
by an approved professional in accordance with
current regulations and codes of practice.

• Warning, hydraulic unit should not be installed
in an air current.

■ Handling

The outdoor unit must not be placed in a horizontal
position during transport.

If not kept upright during transport, the appliance
could be damaged through displacement of
the refrigerant and damage to the compressor
suspension.

Any damage caused by transportation in a horizontal
position is not covered by the warranty.

If necessary, the outdoor unit may be tilted only
during manual handling (to go through a door or up
a staircase). This operation must be conducted very
carefully and the appliance must be immediately
restored to the upright position.

■ Containment of refrigeration circuits

All refrigeration circuits are sensitive to contamination
from dust and moisture. If such pollutants penetrate

the refrigeration circuit, they can a󰀨ect the reliability

of the heat pump.

Make sure that the connections and refrigeration
circuits (hydraulic unit, outdoor unit) are
protected correctly.

In the event of a subsequent failure and following
an inspection, the presence of moisture or
foreign bodies in the compressor oil would
automatically void the warranty.

- Check upon receipt that the ttings and refrigeration
circuit caps mounted on hydraulic unit and outdoor
unit are properly seated and secured (cannot be
loosened with bare hands). If this is not the case,
tighten them using a C spanner.

- Check also that the refrigeration connections are
sealed (plastic caps or tubes crimped at the ends
and brazed). If the caps must be removed during
the installation (tubes to be re-cut for example),
put them back as soon as possible.

■ Hydraulic connections

The connection must comply with industry standard
practice according to current regulations.

Remember: Seal everything when tting in

accordance with industry standard practice for
plumbing work:

- Use suitable seals (bre gasket, O-ring).

- Use Teon or hemp tape.

- Use sealing paste (synthetic depending on the
case).

Use glycol/water mix if the minimum ow

temperature is set below 10°C. If you are using a
glycol/water mix, arrange for an annual check on the
quality of the glycol. Use monopropylene glycol only.
The recommended concentration is 30% minimum.

Never use monoethylene glycol.

• In some installations, the presence of di󰀨erent
metals can cause corrosion problems; the
formation of metal particles and sludge can
appear in the hydraulic circuit.

• In this case, it is advisable to use a corrosion
inhibitor in the proportions indicated by the
manufacturer.

• You must also ensure that treated water does
not become corrosive.

■ Electrical connections

• Before any maintenance operation, ensure

that the general power supply is switched o󰀨.

• Specications of electricity supply

The electrical installation must be carried out in
accordance with prevailing rules.

Electrical connections will only be made once all
other installation operations (fastening, assembly,
etc.) have been completed.

Warning!

The contract signed with the energy provider must

be su󰀩cient not only to cover the heat pump's power

requirements but also the combined sum of all the
appliances likely to be operating at the same time. If
the power is too low, check the power rating stated
in your contract with your energy provider.

Never use a power socket for the power supply.
The heat pump must be supplied directly with power

(without external switch) by special protected leads
from the electric panel via dedicated bipolar circuit
breakers, C curve for the outdoor unit, C curve for
the electrical heating and domestic water backups
(see tables page 35).

The electrical installation must be tted with a 30mA

RCD.
This appliance is designed to operate using a

nominal voltage of 230 V or 400 V, +/- 10%, 50 Hz
(depending on model).

• General remarks on electrical connections

It is essential to maintain neutral-phase polarity
when making electrical connections.

Rigid wires are preferable for xed installations,

particularly in a building.
Tighten the cables using the cable glands to prevent

the feed wires from being accidentally disconnected.
The earth connection and its continuity must be

ensured.

• Cable glands
To ensure the stability of power (Low Voltage) and

sensor (Extra-Low Voltage) cables, it is essential
that the cable glands are tightened according to the
following recommendations:

Size of cable

gland (PE)

(mm)

PG7 1 to 5 1.3 1

- Always select wire that complies with current
standards.

- Bare the end of the wire to around 25 mm.

- With round end pliers, form a loop with a diameter
which matches the tightening screws on the
terminal.

- Tighten the terminal screw rmly onto the

loop created. Insu󰀩cient tightening can cause
overheating, leading to breakdown or even re.

Denitions

►

- Split: The heat pump consists of two elements
(an outdoor unit to be installed outdoors and a hydraulic
unit to be installed inside the dwelling).

- Air/water: The surrounding air is the energy source.
This energy is transmitted to the heating circuit water
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 pulling signicant

amounts of current at start-up.

- COP (Coe󰀩cient of Performance): This is the
relationship between the energy transmitted to the
heating circuit and consumed electrical energy.

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 (R410A) circulates.

- In the evaporator (ref. 13, g. 8, page 12):
The calories are taken from the outside air and
transmitted to the refrigerant. Because it has a low
boiling point, it changes from a liquid to a vapour, even
in cold weather (down to -25°C outside temperature).

- In the compressor (ref. 10, g. 8, page 12):
The vaporised refrigerant is pressurised and takes on
even more calories.

- In the condenser (ref. 14, g. 9, page 13):
The energy of the refrigerant is transmitted to the
heating circuit. The refrigerant returns to its liquid state.

- In the expansion valve (ref. 9, g. 8, page 12):

The liqueed refrigerant is returned to a low pressure

and regains its initial temperature and pressure.

The heat pump is equipped with a controller which
controls the room temperature based on the outdoor
temperature measurement. The room thermostat
(option) provides a corrective action for the temperature
control.

The hydraulic unit is tted with an electrical backup or

boiler connection which intervenes to provide additional
heat during the coldest periods.

• Control functions

- The heating circuit's ow temperature is controlled by
the temperature control.

- Depending on the heating ow temperature,

the outdoor unit's power is modulated by the "Inverter"

compressor.

- Control of the backup electrical heating.

- The daily timer program is used to set the periods
where the ambient temperature is comfortable or
reduced.

- Summer/winter time mode switchover is automatic.

- Management of the boiler backup*.

- Room sensor*: The room sensor provides a corrective
action for the temperature control.

- Control of a second heating circuit*.

- Domestic hot water*: Heating timer program.

- Managing cooling*.

* Where the heat pump is tted with options and associated kits.

• Protective functions

- Anti-legionella cycle for domestic hot water.

- Frost protection: Frost protection cuts in if the heating

circuit's ow temperature falls below 5°C (provided
that the heat pump's electrical power supply is not

interrupted).

• Domestic hot water (DHW) operating principle

Two domestic hot water (DHW) temperatures can be
set: comfort and reduced.

The default DHW program is set to the comfort
temperature between 00:00 and 05:00 and between
14:30 and 17:00 and to the reduced temperature for the
rest of the day. This optimises electrical consumption
while ensuring comfortable heating and water
temperatures.

The reduced temperature setpoint may be useful to
avoid restarting the DHW too often and for too long
during the day.

The production of domestic hot water (DHW) is started
when the temperature in the tank drops to 7°C below
the temperature setpoint.

The heat pump produces the domestic hot water, which

is then additionally heated, if required, by the tank's

electrical backup or by the boiler. To ensure a DHW
setpoint over 55°C, the electrical backup heating must
be left on.

Depending on the setting, the comfort temperature can
be reached 24h/day or only at night or following the
DHW program.

If the contract signed with the energy provider includes

a day/night tari󰀨, the electrical backup is subject to the
supplier’s power tari󰀨 and the comfort temperature may

only be reached at night.
If no particular contract has been signed, 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 managed
by cycles that regulate the amount of time assigned
to heating and production of DHW in the event of
simultaneous demand.

Anti-legionella cycles can be programmed.

connections

Bend the pipes into position and make holes
for them through the oor or walls either with
their protective caps in place or after brazing.

Keep the protective caps in place or ends
brazed until the appliance is commissioned.

The outdoor unit must be connected to the hydraulic unit

only with brand new separately insulated copper
connections (refrigerant quality).

Maintain the same pipe diameters (g. 19).

Observe the maximum and minimum distances

between the hydraulic unit and the outdoor unit
(g. 19, page 24); the guarantee of performance and
the service lifespan of the system depend on this.

The minimum length of the refrigeration
connections for correct operation is 5 m.

The appliance's warranty will be void if it is operated

with refrigeration connections less than 5 m long
(tolerance +/- 10%).

If the refrigeration connections are exposed to
weathering or UV radiation and the insulation is not
resistant, protection must be provided.

Installation precautions

▼

The outdoor unit must only be installed
outside. If a shelter is required, it must have
broad openings on all 4 sides and installation
clearances must be observed.

• Choose the location of the appliance after discussion
with the client.

• We recommend choosing a site that is sunny but
sheltered from strong cold prevailing winds.

• The unit must be easily accessible for future installation
and maintenance work (page 20).

• Ensure that connections to the hydraulic unit can be
made easily.

• The outdoor unit is able to withstand bad weather but
avoid installing it 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 ow out of the outdoor unit when it is
operating. Do not install the unit on a paved terrace;
choose a well-drained location (e.g. gravel or sand).
If installation is carried out in an area where the
temperature stays below 0°C for long periods, check
that the presence of ice does not present any danger.
A drainage pipe can also be connected to the outdoor
unit (see g. 14).

• Nothing should obstruct the air circulation through the
evaporator and out from the fan (g. 13).

• Keep the outdoor unit away from heat sources and

ammable products.

• Make sure that the unit does not disturb the
surrounding area or inhabitants (noise level, draught,
low temperature of the ejected air freezing the plants
in its path).

• The surface on which the appliance is installed must:

- Be permeable (soil, gravel, etc.).

- Support its weight easily.

- Allow a solid fastening base,

- Not transmit any vibration to the dwelling. Anti-vibratory
blocks are available as an option.

• The wall bracket cannot be used where it is likely to
transmit vibrations. Installing the unit on the ground is
preferred.

Positioning Outdoor Unit

▼

The outdoor 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 12).

- Fasten the outdoor unit by means of screws and
rubber tightening or toothed lock washers to prevent
them from coming loose.

H

In areas with heavy snowfall, if the intake and
outlet of the outdoor unit is blocked with snow,

heating may become di󰀩cult and a failure is

likely to occur.

Construct a canopy or place the unit on a high stand

(local conguration).

- Place the unit on a solid stand in order to minimise
impacts and vibrations.

- Do not place the unit directly on the ground as this will
cause problems.

Condensate drain pipe

▼

The outdoor unit can generate a large volume
of water (called condensate).

If the use of a drain pipe is necessary:

- Use the elbow provided (C) and connect a 16 mm­diameter hose for draining the condensate.

- Use the plug(s) provided (B) to block the opening of
the condensate drain pan.

Allow for the condensate to ow away under the force of

gravity (waste water, rain water, gravel bed).

If installation is carried out in an area where the

temperature stays below 0°C for long periods,

equip the drain pipe with trace heating to
avoid it icing up. Trace heating must heat not
only the drain pipe but also the bottom of the
appliance's condensate collection tank.

* In areas with heavy snowfall,

(H) must be higher than the average snow layer.

• 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 not to bring ammable gas

near the heat pump during installation,
in particular when brazing is required.

The appliances are not reproof and should

not therefore be installed in an explosive
environment.

- To avoid condensation inside the condenser, remove
the refrigeration circuit caps only when making the
refrigeration connections.

 Refrigeration connections

This appliance uses refrigerant R410A.

Comply with the legislation on handling of refrigerants.

Rules and precautions

►

Connections must be made on the same day

the installation is lled with gas (see para.

"Filling the installation with gas", page 26).

• Minimum tools required

- Set of pressure gauges (Manifold) with hoses

exclusively designed for HFCs (Hydrouorocarbons).

- Vacuum gauge with isolation valves.

- Vacuum pump specically for HFCs (using a standard

vacuum pump is allowed if, and only if, it is tted with

a non-return valve on the suction side).

- Flaring tool, Pipe-cutter, Deburring tool, Spanners.

- Certied refrigerant leak detector (sensitivity 5g/year).

Using tools that have been in contact with
HCFCs (R22 for example) or CFCs is prohibited.

The manufacturer declines any liability with
regard to the warranty if the above instructions
are not observed.

• Flared connections

Lubricating with mineral oil (for R12, R22)
is prohibited.

- Lubricate only with polyolester oil (POE). If POE is not
available, t without lubrication

Coat the ared surface

with POE refrigeration oil.

Do not use mineral oil.

described above, condensation will form on the
surface of the insulation material. Lastly, use insulating
sleeves whose thermal conductivity will be less than

or equal to 0.045 W/mK if the temperature is equal to

20°C. The insulation must be impermeable in order to
withstand the passage of vapour during the defrosting
cycles (glass wool is prohibited).

Shaping the refrigeration pipes

►

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 breaking them.

Remove the insulation material from the section of
pipe to be bent.

Do not bend copper to an angle greater than 90°.
Never bend pipes more than 3 times in the

same place otherwise traces of fracturing may
appear (hardening of the metal).

Creating the arings

▼

- Cut the pipe to an appropriate length with a pipe-cutter
without damaging it.

- Carefully deburr it, holding the pipe pointing downward

to avoid introducing lings into the pipe.

- Remove the ared connection nut situated on the
valve to be connected and slide the pipe into the nut.

- Proceed to are it, letting the pipe protrude out of the

aring tool's tube.

- After aring, check the state of the working radius (L).
This must not present any scratches or signs of
fracturing. Also check the dimension (B).

• Brazing the refrigeration circuit (if necessary)

- Silver brazing (40% minimum recommended).

- Brazing only with dry nitrogen internal ux.

• Other remarks

- After each maintenance operation on the refrigeration

circuit and before nal connection, take care to put

the caps back in position to avoid any pollution of the
refrigeration circuit.

- To eliminate any lings getting into 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
into the appliance.

- Proceed with thermal insulation of the gas and liquid
pipes to avoid any condensation. Use pipe insulators
resistant to temperatures over 90°C. In addition, if the
humidity level in areas where the refrigerant 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 reaches 70 ~ 80%,
and an insulating material thicker than 20mm if
the humidity exceeds 80%. If the recommended
thicknesses are not observed under the conditions

Additional lling

▼

If additional lling is required, do it before
lling the hydraulic unit with gas. Refer to

paragraph "Additional lling", page 28.

- Remove the access plugs (A) from the valve controls.

- First of all fully open the liquid valve (small) and
then the gas valve (large) using an Allen (hex) key
(anti-clockwise direction) without using excessive
force against the stop.

- Quickly disconnect the hose from the Manifold.

- Ret the 2 original caps (be sure they are clean) and
tighten them to the recommended tightening torque
indicated in the table g. 20, page 25. A seal is
achieved in the caps only with metal to metal.

The outdoor unit does not contain any additional
refrigerant allowing the installation to be bled.

Bleeding by ushing is strictly forbidden.

Final sealing test

▼

The sealing test must be carried out using a certied

gas detector (sensitivity of 5g/year).

Once the refrigeration circuit has been gassed as

described above, check that all the refrigeration

connectors are gas-tight (4 connectors). If the arings

have been made correctly, there should be no leaks.
If necessary, check the seal of the refrigeration valve
caps.

If the event of a leak:

- Return the gas to the outdoor unit (pump down).
The pressure should not drop below atmospheric
pressure (0 relative bar read on the Manifold) so as not
to contaminate the recovered gas with air or moisture.

- Redo the connection,

- Restart the commissioning procedure.

Additional load None 750 g

The amount needed to ll the outdoor units corresponds

to the maximum distances between the outdoor unit

and the hydraulic unit as dened here page 24. If the

distances are greater, an additional amount of R410A
is required. For each type of appliance, this additional
amount depends on the distance between the outdoor

unit and the hydraulic unit. Any additional lling with

R410A must be carried out by an approved specialist.

• Example of additional ll:

An outdoor unit which is 17 m away from the hydraulic

unit will require an additional ll of:
Additional ll = (17 - 15) x 50 = 100 g

Filling must be carried out after creating a vacuum and
before gassing the hydraulic unit, as follows:

- Disconnect the vacuum pump (yellow hose) and
connect a bottle of R410A in its place in the uid

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
value shown on the scales.

- As soon as the value displayed has dropped by the

value for the calculated additional ll amount, close the

bottle and disconnect it.

- Quickly disconnect the hose connected to the
appliance.

- Proceed to ll the hydraulic unit with gas.

The outdoor unit begins cooling operation about
3 minutes after being switched on.

- 4- The circulation pump starts.

- 5- Close the liquid valve on the outdoor unit maximum

30 secs after the outdoor unit starts.

- 6- Close the gas valve on the outdoor unit when
the pressure is below 0.02 relative bar read on the
Manifold, or 1-2 minutes after the liquid valve has been
closed, while the outdoor unit continues to operate.

- 7- Disconnect the power supply.

- 8- Recovery of the refrigerant is complete.

Notes:

- The pump down operation cannot be activated even
if DIP SW1 is set to ON while the heat pump is in
operation.

- Do not forget to switch DIP SW1 back to OFF after
the pump down operation has been completed.

- Select the heating mode.

Temperature control

►

The heat pump's operation is subject to the temperature

control.
The heating circuit water temperature setpoint is

adjusted according to the outdoor temperature.
If there are thermostatic valves on the installation,

these must be fully open or set higher than the normal
temperature setpoint.

Setting

▼

During the installation, the temperature control must be

congured to suit the radiators and level of insulation of

the dwelling.
The temperature control graphs (g. 37) refer to a room

temperature setpoint of 20°C.

The temperature control's gradient determines the

impact of variations in the outdoor temperature on

variations in the heating ow temperature.

The steeper the gradient, the more likely a slight
reduction in the outdoor temperature will cause a

signicant increase in the water ow temperature in the

heating circuit.

The temperature control o󰀨-set modies the ow

temperature of all graphs, without modifying the gradient
(g. 38).

Corrective actions to take in the case of discomfort are
listed in the table (g. 39).

 Maintenance of the installation

Before any maintenance operation,

ensure that the general power supply is switched o󰀨.

Hydraulic checks

►

If frequent rells are required it is absolutely

essential that you check for any leaks. If

relling and a pressure reset are necessary,
check what type of uid was used initially.

Recommended lling pressure: between 1 and 2 bar
(the exact lling pressure is determined by the water

pressure in the installation).

Every year,

- Check the expansion circuit pressure (pre-ination of
1 bar) and the correct operation of the safety valve.

If the installation is tted with a hot water tank:

- Check the safety valve on the cold water supply inlet.
Make it operate as advised by the manufacturer.

- Check the back ow preventer.

Checking the outdoor unit

►

- Remove any dust from the exchanger, if necessary,
while making sure not to damage the blades.

- Straighten the blades using a comb.

- Check that there is nothing blocking the air ow.

- Check the fan.

- Verify that condensate drain is not obstructed.

• Checking the refrigeration circuit

If the amount of refrigerant in the system exceeds
2kg (models > 10kW), the refrigeration circuit must be
checked annually by an approved engineer (they must

have a certicate of competence for the handling of

refrigerants).

- Check there are no leaks (connections, valves…).

Electrical checks

►

- Check the connections and re-tighten if necessary.

- Check the state of the cables and plates.

 Other maintenance

Emptying the hydraulic unit

►

- Remove the front panel of the hydraulic unit.

- Open the drain plug,

- Check that the hydraulic unit's bleeder valve opens
automatically,

- Open the installation’s bleeder valve(s).

- 78 -

Distribution valve

►

If the installation is tted with a hot water tank.
Ensure the distribution valve is tted in the correct

direction.
Channel AB: Outlet to the hydraulic unit.
Channel A open: Return from DHW tank.
Channel B open: Return from the heating circuit.

Waterstage / Installation / 2011 - EN

 Instructions for the end user
