5.1- Placement and positioning
INSTALLATION PRECAUTIONS:
•The appliance must not be installed near
a perpetual ame or other source of ignition.
• The appliance must be installed in such a way as
to avoid mechanical damage.
5.1.1- Placement choice
• It is FORBIDDEN to install the appliance:
- outside;
- in rooms exposed to frost, or where the temperature is less than
5°C, including when the appliance is in operation;
- in humid rooms with signicant vapour emissions;
- to operate the appliance with air intake which contains solvents or
ammable materials.
• Avoid placing near bedrooms to reduce noise pollution.
5.1.3 - On-ground installation
A tripod (see § Options)allows to install
the domestic hot water heat pump on the
ground, in the case where the wall will not
support the weight of the water heater.
The height of the tripod is adjustable from

To adjust the tripod horizontally, each foot
is equipped with an adjustment screw to be
used for this purpose.
Even for on-ground tting, the domestic
hot water heat pump should be anchored
to the wall to avoid any danger of tipping or
falling.
5.1.4 - Wall mounting
For a durable and perfectly vertical anchoring, it is recommended to use
the wall fastening bracket(s) (available as an optional extra).
This bracket is pre-
drilled with various
interaxial distances:
250mm, 350mm or
440mm. This enables
inpart,amoredurable
wall mounting
through the use of 4
xation points instead
of 2, and also allows
for easier positioning
with the use of a level.
Ensure the solidity of
the wall to be able to
support the weight
of a full water heater.
Weight with water:
Water heater 150L = 207.5kg
Leave a space of 300mm free under the appliance for access to the
anode and the electrical back-up.

The domestic hot water heat pump is not compatible with a radiator
circuit (the volume of water in the radiators is insucient, and
condensation will form on the surface of the radiators during the
summer months).
5.2.3 - Radiators
To avoid operation of the heat pump using the electrical back-up
instead of the heat pump, a minimum surface area for underoor
heating should be respected according to the capacity of the
appliance:
5.2.4 - Minimum surface area for underoor
heating
Domestic hot water heat pump Minimum surface area of
underoor heating
150 L 60 m²
5.2- Hydraulic connections to
underoor heating
The appliance is connected using the return ow of the underoor
heating network via a derivation module provided with the tank.
5.2 .1- Underoor heating derivation module
5.2.1.1- Description
The floor derivation module is a hydraulic accessory which is
delivered as standard with the heat pump, which allows the
connection of the domestic hot water heat pump to the water return
ow from the underoor heating circuit.
For water return over 50°C, installation of a primary circuit
thermostatic mixing valve is necessary >50°C (see §Options).

The length and diameter of the plumbing inlet/outlet connection
between the oor derivation module and the domestic hot water
heat pump must be adapted to the circulator so that the ow drawn
from the oor is more than 250 l/h.
Example above without thermostatic mixing valve: with 20m of
connection with an interior diameter of 14 mm, the total loss of load
is 2.00m for a owrate of 325 l/h.
It is recommended to install a lter on the inlet piping of the water
heater to protect the circulator and the plated heat exchanger.

5.2.7 - Underoor heating circuit circulator
To help the circulator equipping the domestic hot water heat pump
if it is distanced from the derivation module (long distance or the
diameter of connection is too weak), let the underoor heating circuit
circulator (rep.17) run permanently, summer and winter.
This allows to limit operation of the appliance using the electrical
back-up instead of the heat pump.
If there are thermostatically controlled valves equipping the
recirculating pumps for the underfloor heating circuit on the
appliance, (rep.18), leave them permanently open (by manually
opening them or by disassembling the thermostatic head).
The permanently irrigated flooring should have the minimum
surface area necessary for the capacity of the appliance.
This is to avoid damaging the circulator equipping the domestic hot
water heat pump and limits the running of the electrical back-up
instead of the heat pump.
5.2.6 - Thermostatic mixing valves equipping the
water loops of the underoor heating circuit
With the presence of a 3-way mixing valve (rep.16), it is imperative to place the derivation kit between the underoor heating collector and
the 3-way valve bypass as indicated on the diagram below:
5.2.5 - 3-way mixing valve for underoor heating circuit

- INSTALLER DOMESTIC HOT WATER HEAT PUMP 150L MANUAL -

5.2.9 - Filling water
The materials used for the production of a heating circuit have
diering properties. These properties can create a phenomena
of corrosion through the creation of a galvanic bridge in new
installations as well as in older ones.
The lling of the water circuit must be done only with water from
the domestic water network using untreated water (no softener).
Using water from any other source (well water, rain water, etc..) will
render the warranty null and void.
5.2.10 - Treatment of the heating circuit
Central heating systems MUST BE
CLEANED to eliminate debris (copper,
bres, soldering uxes) related to set-up and
installation, as well as to avoid chemical reactions
between the metals.
It is also important to TO PROTECT THE
CENTRAL HEATING SYSTEM AGAINST RISKS
OF: CORROSION, LIMESCALE, AND MICROBIAL
DEVELOPMENT by using an APPROPRIATE
corrosion inhibitor for all types of installations
(steel or cast-iron radiators, underoor heating).
PRODUCTS USED FOR THE TREATMENT OF
HEATING WATER USED MUST COMPLY WITH
ALL NATIONAL STANDARDS IN THE COUNTRY
OF INSTALLATION.
We recommend the use of products in the SENTINEL range for
preventative and curative treatment of the heating circuit.
• For new installations : (less than 6 months old):
- Clean the installation with a universal cleaner to eliminate
the debris from the installation (copper, bres, soldering
uxes) Example: SENTINEL X300 or SENTINEL X800.
- Thoroughly rinse the installation until the water runs clear,
with no traces of impurities left.
- Protect the installation against corrosion with a corrosion
inhibitor, example: SENTINEL X100. Or against corrosion
and freezing with an inhibitor with an anti-freeze additive.
Example: SENTINEL X500 or SENTINEL R600.
• For existing installations:
- Desludge the installation with a desludging product
to eliminate any sludge from the installation. Example:
SENTINEL X400 or SENTINEL X800.
-Thoroughly rinse the installation until the water runs clear,
with no traces of impurities left.
5.2.11- Purging the installation
The oxygen present in the air is extremely corrosive. Therefore,
for a permanent purging of the installation to be effective,
place automatic or manual air purgers at each high point of the
installation, and manual purgers on each radiator.
All deterioration of the appliance due to
an inappropriate quality of water and/
or the presence of corrosion in the absence of
treatment products as described above, and/or
an improper purging of air of the installation will
render the warranty null and void.
RENDERING THE WARRANTY NULL AND VOID
• Connect the oor derivation module to the return ow of the
underoor heating of the installation. Take care of the proper
orientation of the check valve (see § «Underoor heating derivation
module» and «Description»).
- Protect the installation against corrosion with a corrosion
inhibitor, example: SENTINEL X100. Or against corrosion
and freezing with an inhibitor with an anti-freeze additive.
Example: SENTINEL X500 or SENTINEL R600.
Corrosion inhibitor:
- protects against the formation of limescale
- prevents «pinhole» type corrosion
- prevents in new installations,the formation of sludge and
the proliferation of bacteria
(in low temperature networks: algae)
- prevents the formation of hydrogen
- eliminates the sound of the generators
Treatment products from other manufacturers can be used if they
guarantee that the product is appropriate for all the materials used
in the appliance and oers ecient resistance to corrosion. To nd
this information refer to their user manual.
5.3 - Connection to the domestic water
supply
• A new pressure-relief valve (not included)must be installed and set
to 6 bars on the domestic cold water supply of the appliance. The
use of a membrane valve is recommended.This valve must conform
to all local and national standards.
• The pressure-relief valve should be installed as close as possible to
the appliance’s cold water inlet and the water ow should never be
hampered by any accessory (valve, pressure-reducer, etc.).
• The pressure-relief valve drainage outlet should be sized
according to building regulations and standards and must never
be obstructed. It should be connected to a vertically draining
pipe, using a funnel which allows an open space of at least 20mm
and which is at least equal in diameter to the appliance’s piping
connection.
• The pressure-relief valve drainage outlet must be installed in a
frost-free place and in a downward-sloping position.
• If the pressure of the domestic cold water supply is higher than 5
bars, a pressure-reducer should be installed above the pressure-
relief valve near the starting point of the installation (a pressure
of 3-4 bars is recommended).
• It is advised to t a shut-o valve above the pressure-relief valve.
• For installations equipped with:
- piping of a small diameter
- ceramic plate valves
A domestic water expansion vessel, or anti-hammer valves which
are adapted to the installation should be installed as close as
possible to the shut-o valve.
5.2.8 - Treatment of the water in the heating
circuit
If the domestic hot water heat pump is connected to an installation
with existing underoor heating, it is necessary to thoroughly rinse
and treat the installation.
It is MANDATORY to read the additional
document concerning the quality of
water used for lling the installation.This
document is included with this manual as well
as in the packet with the warranty information.
This document also contains information which is
PERTINENT to the WARRANTY of the material.

- INSTALLER DOMESTIC HOT WATER HEAT PUMP 150L MANUAL - 13
The warranty does not apply if any of these
points have been neglected or if the water
quality did not allow correct treatment within
the legal framework or if regular inspections of
the anode are not carried out.
• The following materials should be used for the
domestic hot water circuit:
- copper
- stainless steel
- brass
- plastic
If the materials used in the domestic hot water circuit
are incompatible, corrosion damage may occur.
Domestic hot water pipes with a cast-iron or steel link, or with

bridge.
• Thoroughly flush the supply line piping before connecting the
appliance to the domestic installation so as not to introduce any
particles, metallic or other, into the appliance.
• Respect the standards in eect in the country of use, notably domestic
water regulations and pressure safety regulations.
• The maximum domestic hot water temperature at the distribution
points should never surpass 50oC for toilets, and 60oC for other uses.
Adequate thermostatic mixing valves should be installed to avoid
risk of burns.
• In regions with extremely hard water (TH>25°F), it is recommended
to treat water with a softener. The softened water must respect the
criteria dened by the DTU 60-1 (TH>12°F).
• The appliance must operate using water with a TH between 12°F
and 30°F. In regions with extremely hard water (TH>25°F), it is
recommended to treat water with a softener.
• Not following the conditions shown below, see DTU 60-1, will lead
to the warranty of the tank to be rendered null and void (the values
are given for a water at 20°C).

Do not connect the domestic hot
water heat pump to the eletrical line
of a pre-existing water heater which
used the peak / o-peak hours contact.
The domestic hot water heat pump must be
permanently connected to the power supply,
and the peak / o-peak control is done by
either programming, or through the use of an
independent cable.
Grounding is mandatory.
Power supply = 230V single phase + ground.
The power supply should comply with all regulations in eect in the
country of installation, as well as the NFC 15-100 standard.
A method of disconnection which ensures a total power-cut
in category III conditions should be installed in xed piping in
compliance with the installation rules.
Protect the appliance with:
• a 6 A all-pole circuit breaker with a minimum 3mm contact
opening.
• a protective 6 A circuit breaker with a 30mA dierential.
If the power supply cable is damaged it must be replaced by the
manufacturer, their customer service technicians, or by a qualied
technician to avoid any risk of injury or danger.
It is also possible to connect the electricity provider dry contact to
the domestic hot water heat pump without using programming.
- Contact open = Load shedding
- Contact closed = Normal operation
The load shedding level can be selected and programmed for the
appliance (see § «Load shedding»).
By default, the electrical back-up does not run during peak hours.

the appliance or connecting it to the electrical
supply.
6.1 - Control panel
6 - SET-UP AND USE
• Leave the appliance unplugged.
• Open the hot water valve located at the highest point of the
installation.
• Open the cold water inlet located on the safety group.
• Fill the tank until water is coming out of the hot water vavle located
at the highest point of the installation.
• Close the hot water valve
Before turning on the appliance, verify that the entire circuit is
watertight.
The domestic hot water heat pump operates primarily with the heat
pump as long as the temperature of the water from the underoor
heating return ow is between
18°C and 50°C. Once the temperature
is lower than 18°C or over 50°C, the water is no longer heated by the
heat pump, but by the electrical back-up.
The temperature of the domestic hot water provided by the heat
pump is adjustable to up to 60°C.
In the case of high domestic hot water consumption, the domestic
hot water heat pump has a comfort function, t°C mini which increases
the heating capacity when there is less than 1/3 of the tank’s volume
left at over 38°C (see § «t°c mini -minimum temperature-»). There is
also a setting to activate the electrical back-up if the heating time
is too long (see § «max time»).
If more domestic hot water is required from time to time, the
domestic hot water heat pump has a « boost» function (activated
by the user) which ensures that the water heats to the desired
temperature (
for example: 50°C ) quickly with the help of the heat
pump and electrical back-up.This function is deactivated as soon as
the required temperature is reached (end of heating cycle).
From time to time, check that there are no alerts (in case of an alert,
please refer to § «Error message codes»).
