▪ Generalinstallationsiterequirements.Seethe"General
safetyprecautions"chapter.
▪ Service space requirements. See the "Technical data"
chapter.
▪ Refrigerant piping requirements (length, height
difference).Seefurtherinthis"Preparation"chapter.
Mindthefollowing:
▪ Selectaplacewhereraincanbeavoidedasmuchaspossible.
▪ Take care that in the event of a water leak, water cannot cause
anydamagetotheinstallationspaceandsurroundings.
▪ Choosealocationwherethehot/coldairdischargedfromtheunit
ortheoperationnoise,willNOTdisturbanyone.
▪ Heatexchanger fins are sharp and injury is possible. Choose an
installationlocation where thereisnorisk for injury(especiallyin
areaswherechildrenplay).
DoNOTinstalltheunitinthefollowingplaces:
▪ Soundsensitiveareas(e.g.nearabedroomandthelike),sothat
theoperationnoisewillcausenotrouble.
Note: If the sound is measured under actual installation
conditions, the measured value might be higher than the sound
pressurelevelmentionedinSoundspectruminthedatabookdue
toenvironmentalnoiseandsoundreflections.
INFORMATION
Thesoundpressurelevelislessthan70dB(A).
▪ In places where a mineral oil mist, spray or vapour may be
presentin the atmosphere. Plastic parts may deteriorate and fall
offorcausewaterleakage.
It is NOT recommended to install the unit in the following places
becauseitmayshortenthelifeoftheunit:
▪ incoastalareasorotherplaceswheretheaircontainshighlevels
ofsalt.Corrosionmayoccur,
▪ wherethevoltagefluctuatesalot,
▪ invehiclesorvessels,
▪ whereacidicoralkalinevapourispresent.
When the outdoor unit is subject to windy and/or low ambient
temperatures,mindthefollowingguidelines:
Strongwinds(≥18km/h)blowingagainsttheoutdoorunit’sairoutlet
causesshortcircuit(suctionofdischargeair).Thismayresultin:
▪ deteriorationoftheoperationalcapacity;
▪ frequentfrostaccelerationinheatingoperation;
▪ disruption of operation due to decrease of low pressure or
increaseofhighpressure;
▪ a broken fan (if a strong wind blows continuously on the fan, it
maystartrotatingveryfast,untilitbreaks).
It is recommended to install a baffle plate when the air outlet is
exposedtowind.
Itisrecommendedtoinstalltheoutdoorunitwiththeairinletfacing

6.5 Checkingtherefrigerantpiping
6.5.1 Aboutcheckingtherefrigerantpiping
Theoutdoorunit'sinternalrefrigerantpipinghasbeenfactorytested
for leaks. You only have to check the outdoor unit's external
refrigerantpiping.
Beforecheckingtherefrigerantpiping
Make sure the refrigerant piping is connected between the outdoor
unitandtheindoorunit.
Typicalworkflow
Checking the refrigerant piping typically consists of the following
stages:
1 Checkingforleaksintherefrigerantpiping.
2 Performing vacuum drying to remove all moisture, air or
nitrogenfromtherefrigerantpiping.
If there is a possibility of moisture being present in the refrigerant
piping (for example, rainwater may have entered the piping), first
carryoutthe vacuum drying procedure below until all moisture has
beenremoved.
6.5.2 Precautionswhencheckingthe
refrigerantpiping
