1Instructions to be read before using the
equipment.
Please comply with the following instructions in order
to avoid any risk of injury or inappropriate use of the
appliance.
1.1 Safety instructions
1.1.1 Start-up
FDo not switch the appliance on until every
fillings have been done.
FDo not try to install this appliance yourself.
FThis heat pump requires an appropriately
qualified person to install it.
FThe installation must always be connected to
the Earth and fitted with a protective circuit
breaker.
FDo not modify the electricity supply.
FThe appliances are not fireproof and should
therefore not be installed in a potentially
explosive atmosphere.
1.1.2 Use
FDo not let children insert foreign bodies into
the fan protection grill or climb on top of the
outside unit. The fins on the air exchanger are
extremely fine and cause cuts.
FNothing should obstruct the air circulation
through the evaporator and from the fan.
FDo not climb on the top of the outside unit.
FThe room in which the appliance is operating
must be correctly ventilated in order to
prevent any loss of oxygen if there is an
escape of refrigerant gas.
FConsult your Installer before making any
changes or modifications to the premises
where the appliance is installed.
FDo not place any heat source under the
remote control.
1.1.3 Maintenance
FDo not try to repair this appliance yourself.
FTh i s a ppl i ance d o e s not co n t a in an y
components capable of being repaired by the
user himself. Removing one or other of the
covers can expose you to dangerou s
electrical voltages.
FIn any case, switching off the current is not
sufficient to protect you from any external
electrical shocks (capacitors)
FDo not open the outside unit or the hydraulic
unit while they are operating.
FSwitch off the power supply if there are any
abnormal noises, smells or smoke coming
from the appliance and contact your installer.
FSwitch off the power to the appliance before
you clean it.
FDo not use aggressive cleaning liquid or
solvents to clean the body work.
FDo not use a pressure washer to clean the
outside unit. This could damage the air
exchanger and the water might penetrate into
the electrical circuits.
Instruction manual “1353-EN” 3
Heat pump, split, single service

1.2 Precautions and warnings regarding
your installation.
1.2.1 The outside unit
The outside unit contains the equipment for
capturing energy from the ambient air.
Your installer has placed this unit in a location that
enables it to operate in an optimum manner.
Nothing should obstruct the air circulation through
the evaporator and from the fan.
The ambient air is cooled in the outside unit in
contact with an exchanger. The water that the air
contains condenses and flows from the outdoor unit.
In cold periods, this water freezes in contact with the
exchanger and is drained away by regular defrosting
cycles. The control system automatically controls the
defrosting cycle, whose operation can lead to the
quite normal emission of steam.
1.2.2 The hydraulic unit
The hydraulic unit contains the heat pump complete
control system, in charge of controlling the heating
comfort level and the production of domestic hot
water (if a DHW tank is connected).
The hydraulic module is equipped with an electric
back-up system, which is designed to provide
additional heat during the coldest periods.
1.2.3 Control system
Your installer has carefully adjusted your installation.
Do not modify setting parameters without his
agreement. If in doubt, do not hesitate to contact him.
The control system for your heating system is
designed:
-either as a fixed flow temperature for the water (only
for low temperature radiators with thermostatic
valve controls).
-Or as a flow temperature for the water based on the
external temperature (water control) with the
installation of an ambient air sensor (option).
This second solution (water control) is the only one
usable for Floor-heating systems. It is also very
effective for thermostatically controlled radiators.
1.2.4 Floor-heating systems
•New floor-heating systems require to be initially
heated slowly to avoid any problems with cracking.
Check with your installer that this initial heating
procedure has indeed been performed before using
your heating system freely.
•To be efficient, floor-heating systems do not need to
be very hot and never should be. At most, the
systems should be warm to the touch in cold
weather.
•The great stability in a regulation system for
floor-heating systems avoids sharp differences in
temperature. However, this stability involves a
reaction time of the order of several hours, (approx
6 hours).
•Any changes to the setting must be made slowly,
leaving the installation time to react. Adjusting the
system to exaggerated setting or in an untimely
manner always results in significant temperature
fluctuations during course of the day.
•Similarly if your dwelling has a floor-heating system,
do not reduce the heating or switch it off if you will be
absent for a short period. The reheating period is
always quite long (approx 6 hours).
1.2.5 Domestic hot water (DHW)
This function is designed as an option through the
use of a DHW tank with electrical backup heating.
When the DHW production is required, the heat
pump adapts to this demand as a priority.
No space heating is produced while the domestic hot
water is being prepared.
The heat pump produces the domestic hot water,
which is then supplemented, if required, by electrical
backup heating inside the tank.
The electrical backup heating enables anti-legionella
cycles to be conducted efficiently.

Heat pump, split, single service

2Overall view of the installation
Your heat pump has been configured by your
installer. It is composed of the following main
elements:
-The outside unit is positioned, as its name
indicates, outside your dwelling and extracts
energy from the outside air.
-The hydraulic unit positioned in your boiler room,
cellar, garage or even your kitchen, transfers the
energy to the heating circuit (and the domestic hot
water).
-T h e o u t d o o r s e n s o r d e t e c t s t h e o u t s i d e
temperature.
Optional equipment:
-Room thermostat
-Remote control
Heat pumps are systems that can be connected to
any form of low temperature heat distribution
systems: the heat captured by the heat pump can
therefore be used in different ways:
-Floor-heating systems
-Radiators or warm fan coil heaters
-Domestic hot water (DHW)

3.2 Appliance start up.
•The installation and 1st start up of the appliance
must be done by a qualified installer. That person
will also give you instructions on starting and
running the appliance.
•Ensure that the installation is fully filled with water
and has been correctly bled and that there is a
sufficient press u r e of 1.5 to 2 bars on the
manometer (Ref. 2, fig. 4).
•Close the installation’s main circuit breaker.
In winter, so that the compressor can be preheated,
close the installation’s main circuit breaker (outside
unit’s power supply) some hours before pressing the
on/off button.
3.3 Quick start-up
Once your installer has started your installation for
the first time:
•Engage the heat pump’s ON/OFF button.
During the regulator initialisation phase, the display
shows all the symbols and then “Data, update” and
then “State heat pump”.
•Select the “AUTO” heating mode (Fig. 5).
•Select the DHW mode (Fig. 5)
if the installation is fitted with a DHW tank with
electrical back-up heating.
•Set the current date and time (Fig. 6).

4Maintenance
In order to insure your appliance operates correctly
for many years, the maintenance operations
described below are required at the start of each
heating season. Generally, these are performed as
part of a service contract.
4.1 Checking that the floor system is
full
The pressure in the floor system when it is cold and
when it has stopped must be 1.5 bars.
If filling and re-pressurisation are required, check
what type of fluid has been used initially.
If in any doubt, contact your installer.
Warning, if frequent filling is required, have the
installation’s sealing checked.
4.2 Checking the outside unit
Dust off the exchanger if necessary, being careful not
to damage the fins.
Check that there is nothing obstructing the passage
of air.
4.3 Checking the refrigeration circuit
When the coolant fluid charge is in excess of 2kg
(095, 112, 128, 140,155 and 160 models), it is
compulsory to have an approved after sales service
check the refrigeration circuit every year. Consult
your heating technician.
