1.4 Safetyprecautions
CAUTION
Install the system in full accordance with this
installation manual.
Incorrectinstallationcancausebursts,personalinju-
ry,waterleaks,refrigerantleaks,electricshocksand
re.
Pay attention to the measurement values before
working on the cooling system, especially when
servicing in small rooms, so that the limit for the
refrigerant’s concentration is not exceeded.
Consultanexperttointerpretthemeasurementval-
ues.Iftherefrigerantconcentrationexceedsthelimit,
theremaybeashortageofoxygenintheeventofany
leak,whichcancauseseriousinjury.
Use original accessories and the stated compo-
nents for the installation.
Ifpartsotherthanthosestatedbyusareused,
waterleaks,electricshocks,reandpersonalinjury
mayoccurastheunitmaynotworkproperly.
Ventilate the working area well – refrigerant leak-
age may occur during service work.
Iftherefrigerantcomesintocontactwithnaked
ames,poisonousgasiscreated.
Install the unit in a location with good support.
Unsuitableinstallationlocationscancausetheunitto
fallandcausematerialdamageandpersonalinjury.
Installationwithoutsucientsupportcanalsocause
vibrationsandnoise.
Ensure that the unit is stable when installed, so
that it can withstand earthquakes and strong
winds.
Unsuitableinstallationlocationscancausetheunitto
fallandcausematerialdamageandpersonalinjury.
The electrical installation must be carried out by
a qualied electrician and the system must be
connected as a separate circuit.
Powersupplywithinsucientcapacityandincorrect
functioncancauseelectricshocksandre.
Use the stated cables for the electrical connec-
tion, tighten the cables securely in the terminal
blocks and relieve the wiring correctly
to prevent overloading the terminal blocks.
Looseconnectionsorcablemountingscancauseab-
normalheatproductionorre.

Do not install the unit where corrosive gas (for
example nitrous fumes) or combustible gas or
steam (for example thinner and petroleum gases)
can build up or collect, or where volatile combus-
tible substances are handled.
Corrosivegascancausecorrosiontotheheatex-
changer,breaksinplasticpartsetc.andcombustible
gasorsteamcancausere.
Do not use the unit where water splashes may
occur, for example in laundries.
Theindoorsectionisnotwaterproofandelectric
shocksandrecanthereforeoccur.
Do not use the unit for specialist purposes such
as for storing food, cooling precision instru-
ments, freeze-conservation of animals,
plants or art.
Thiscandamagetheitems.
Do not install and use the system close to equip-
ment that generates electromagnetic elds or
high frequency harmonics.
Equipmentsuchasinverters,standbysets,medical
highfrequencyequipmentandtelecommunications
equipmentcanaecttheunitandcausemalfunctions
andbreakdowns.Theunitcanalsoaectmedical
equipmentandtelecommunicationsequipment,
sothatitfunctionsincorrectlyornotatall.
Do not install the outdoor unit in the locations
stated below.
● Locationswhereleakageofcombustiblegascan
occur.
● Locations where carbon bre, metal powder or
otherpowderthatcanentertheair.
● Locations where substances that can aect the
unit, forexample, sulphide gas, chlorine,acid or
alkalinesubstancescanoccur.
● Locationswithdirectexposuretooilmistorsteam.
● Vehiclesandships.
● Locationswheremachinesthatgeneratehighfre-
quencyharmonicsareused.
● Locations where cosmetic or special sprays are
oftenused.
● Locationsthatcanbesubjectedtodirectsaltyat-
mospheres.Inthiscase,theoutdoorunitmustbe
protectedagainstdirectintakesofsaltyair.
● Locationswherelargeamountsofsnowoccur.
● Locationswherethesystemis exposed tochim-
neysmoke.
Check, after completed installation or service,
that no refrigerant leaks from the system in gas
form. Ifrefrigerantgasleaksintothehouseand
comesintocontactwithanaerotemp,anovenoroth-
erhotsurface,poisonousgasesareproduced.
Switch o the compressor before opening/
breaching the refrigerant circuit.
Iftherefrigerantcircuitisbreached/openedwhilstthe
compressorisrunning,aircanentertheprocesscir-
cuit.Thiscancauseunusuallyhighpressureinthe
processcircuit,whichcancauseburstsandpersonal
injury.
Switch o the power supply in the event of a ser-
vice or inspection.
Ifthepowersupplyisnotshuto,thereisariskof
electricshocksanddamageduetotherotatingfan.
Do not run the unit with removed panels or pro-
tection.
Touchingrotatingequipment,hotsurfacesorhigh
voltagepartscancausepersonalinjuryduetoentrap-
ment,burnsorelectricshocks.
Cut the power before starting electrical work.
Failuretocutthepowercancauseelectricshocks,
damageandincorrectfunctionoftheequipment.
CARE
Carry out the electrical installation with care.
Donotconnectthegroundleadtothegasline,wa-
terline,lightningconductorortelephoneline'sground
lead.Incorrectgroundingcancauseunitfaultssuch
aselectricshocksduetoshort-circuiting.
Use main switch with sucient breaking
capacity.
Iftheswitchdoesnothavesucientbreaking
capacity,malfunctionsandrecanoccur.
Always use a fuse with the correct rating
in the locations where fuses are to be used.
Connectingtheunitwithcopperwireorother
metalthreadcancauseunitbreakdownandre.
Cables must be routed so that they are not
damaged by metal edges or trapped by panels.
Incorrectinstallationcancauseelectricshocks,
heatgenerationandre.
Do not install the unit in close proximity to loca-
tions where leakage of combustible gases can
occur.Ifleakinggasescollectaroundtheunit,re
mayoccur.

If the bottom frame of the outdoor section is cor-
roded, or in any other way damaged, due to long
periods of operation, it must not be used.
Usinganoldanddamagedframecancausetheunit
tofallandcausepersonalinjury.
If soldering near the unit, ensure that solder
residue does not damage the drip tray.
Ifsolderresidueenterstheunitduringsoldering,
smallholescanappearinthetrayresultinginwater
leakage.Topreventdamage,keeptheindoorunitin
itspackingorcoverit.
Do not allow the drainage pipe to exit into
channels where poisonous gases, containing
sulphides for example, can occur.
Ifthepipeexitsintosuchachannel,anypoisonous
gaseswillowintotheroomandseriouslyaectthe
user'shealthandsafety.
Insulate the unit's connection pipes so that the
ambient air moisture does not condense on them.
Insucientinsulationcancausecondensation,which
canleadtomoisturedamageontheroof,oor,furni-
tureandvaluablepersonalproperty.
Do not install the outdoor unit in a location where
insects and small animals can inhabit.
Insectsandsmallanimalscanentertheelectronic
partsandcausedamageandre.Instructtheuser
tokeepthesurroundingequipmentclean.
Take care when carrying the unit by hand.
Iftheunitweightsmorethan20kg,itmustbecarried
bytwopeople.Wearsafetyglovestominimisethe
riskofcuts.
Dispose of any packaging material correctly.
Anyremainingpackagingmaterialcancauseperson-
alinjuryasitmaycontainnailsandwood.
Do not touch any buttons with wet hands.
Thiscancauseelectricshocks.
Do not touch any refrigerant pipes with your
hands when the system is in operation.
Duringoperationthepipesbecomeextremelyhotor
extremelycold,dependingonthemethodofopera-
tion.Thiscancauseburninjuriesorfrostinjuries.
Do not shut o the power supply immediately
after operation has start.
Waitatleast5minutes,otherwisethereisariskof
waterleakageorbreakdown.
Do not control the system with the main switch.
Thiscancausereorwaterleakage.Inaddition,the

Savingtips
Yourheatpumpinstallationproducesheatandcool-

Factorsthataecttheenergyconsumptionare,for

tion,theinsulationlevelofthehouseandwhetherthe
househasmanylargewindowsurfaces.Theposition
ofthehouse,e.g.windexposureisalsoanaecting
factor.
Alsoremember:
● Openthethermostatvalvescompletely(exceptin
the rooms that are to be kept cooler for various
reasons, e.g. bedrooms). The thermostats slow
the ow in the heating system, which the heat
pump wants to compensate with increased tem-
peratures. It then works harder and consumes
moreelectricalenergy.
● Reduce or adjust the settings for heating in any
externalcontrolsystems.
