Split system1 Instructions to be read before using the equipmentPlease comply with the following instructions in orderto avoid any risk of injury or inappropriate use of theappliance.1.1 Safety instructions1.1.1 Start-up""Do not switch the appliance on until everyfillings have been done.""Do not try to install this appliance yourself.""This heat pump requires an appropriatelyqualified person to install it.""The installation must always be connected tothe Earth and fitted with a protective circuitbreaker.""Do not modify the electricity supply.""The appliances are not fireproof and shouldtherefore not be installed in a potentiallyexplosive atmosphere.1.1.2 Use""Do not let children insert foreign bodies intothe fan protection grill or climb on top of theoutdoor unit. The fins on the air exchanger areextremely fine and cause cuts.""Nothing should obstruct the air circulationthrough the evaporator and from the fan.""Do not climb on the top of the outdoor unit.""The room in which the appliance is operatingmust be correctly ventilated in order to preventany loss of oxygen if there is an escape ofrefrigerant gas.""Consult your Installer before making anychanges or modifications to the premises wherethe appliance is installed.""Do not place any heat source under the roomcontrol unit .1.1.3 Maintenance""Do not try to repair this appliance yourself.""This appliance does not contain any componentscapable of being repaired by the user himself.Removing one or other of the covers can exposeyou to dangerous electrical voltages.""In any case, switching off the current is notsufficient to protect you from any externalelectrical shocks (capacitors).""Do not open the outdoor unit or the hydraulicunit while they are operating.""Switch off the power supply if there are anyabnormal noises, smells or smoke coming fromthe appliance and contact your installer.""Switch off the power to the appliance beforeyou clean it.""Do not use aggressive cleaning liquid orsolvents to clean the body work.""Do not use a pressure washer to clean theoutdoor unit. This could damage the airexchanger and the water might penetrate intothe electrical circuits.Operation manual "1328 - EN" - 3 -

Split system1.2 Precautions and warnings regardingyour installation.1.2.1 The outdoor unitThe outdoor unit contains the equipment for capturingenergy from the ambient air.Your installer has placed this unit in a location thatenables it to operate in an optimum manner.Nothing should obstruct the air circulation through theevaporator and from the fan.The control system for your heating system is designedin flow temperature for the water based on the outdoortemperature (water control).In cold periods, this water freezes in contact with theexchanger and is drained away by regular defrostingcycles.The control system automatically controls the defrostingcycle, whose operation can lead to the quite normalemission of steam.1.2.2 The hydraulic unitThe hydraulic unit contains the heat pump completecontrol system, in charge of controlling the heatingcomfort level and the production of domestic hot water(if the installation is fitted with a DHW tank with electricalback-up heating).The heat pump is equipped with an electric back-upsystem, which is designed to provide additional heatduring the coldest periods.1.2.3 Control systemYour installer has carefully adjusted your installation. Donot modify setting parameters without his agreement. Ifin doubt, do not hesitate to contact him.The control system for your heating system is designedin flow temperature for the water based on the outdoortemperature (water control).The installation of a room thermostat (option) allows toimprove operation of the regulation (the influence of theroom temperature is taken into account).1.2.4 Fan convectors with integrated control systemDo not use a room sensor in the area.1.2.5 The radiatorsTo ensure the function of the regulation with roominfluence, it's necessary that the room in which the roomthermostat is installed has no thermostatic valve or thatthey must be completely open.1.2.6 Floor-heating systemsNew floor-heating systems require to be initially heatedslowly to avoid any problems with cracking. Checkwith your installer that this initial heating procedurehas indeed been performed before using your heatingsystem freely.To be efficient, floor-heating systems do not need tobe very hot and never should be. At most, the systemsshould be warm to the touch in cold weather.The great stability in a regulation system for floor-heatingsystems avoids sharp differences in temperature.However, this stability involves a reaction time of theorder of several hours, (approx 6 hours).Any changes to the setting must be made slowly, leavingthe installation time to react. Adjusting the system toexaggerated setting or in an untimely manner alwaysresults in significant temperature fluctuations duringcourse of the day.Similarly if your dwelling has a floor-heating system,do not reduce the heating or switch it off if you will beabsent for a short period. The reheating period is alwaysquite long (approx 6 hours).1.2.7 Domestic hot water (DHW)This function is designed as an option through the useof a DHW tank with electrical backup heating.When the DHW production is required, the heat pumpadapts to this demand with higher priority.No space heating is produced while the domestic hotwater is being prepared.Domestic hot water (DHW) is produced by the heatpump and then topped up, if necessary, by electricalbackup heating or the boiler.To ensure a DHW setting over 45°C, the electricalbackup heating or the boiler must be left on.The electrical backup heating enables anti-legionellacycles to be conducted efficiently.- 4 -Operation manual "1328 - EN"

Split system2 Overall view of the installationYour heat pump has been configured by your installer. Itis composed of the following main elements :--The outdoor unit is positioned, as its name indicates,outside your dwelling and extracts energy from theoutside air.--The hydraulic unit positioned in your boiler room, cellar,garage or even your kitchen, transfers the energy tothe heating circuit (and the domestic hot water).--The outdoor sensor detects the outdoor temperature.Optional equipment :--Room thermostat.--Room control unit.Heat pumps are systems that can be connected to anyform of low temperature heat distribution systems : theheat captured by the heat pump can therefore be usedin different ways :--Floor-heating systems.--Radiators or fan coil heaters.--Domestic hot water (DHW).OutdoorsensorRoomthermostatRoomcontrol unitHeating circuitFloor heating systemor / andControl optionsOptionsdependingon the systemconfigurationsHeating circuitRadiators orfan convectorsor2nd circuit kitDHW kitDHW tank(with electricalback-up heating)The hydraulic unitBoilerconnexion kitThe outdoor unitfigure 1 - Overall view of the configuration of a complete installationOperation manual "1328 - EN" - 5 -
