6.8.3 Tochecktheinsulationresistanceofthe
compressor
NOTICE
If, after installation, refrigerant accumulates in the
compressor, the insulation resistance over the poles can
drop,butifitisatleast1MΩ,thentheunitwill notbreak
down.
▪ Usea500Vmegatesterwhenmeasuringinsulation.
▪ Donotuseamegatesterforlowvoltagecircuits.
1 Measuretheinsulationresistanceoverthepoles.
If Then
≥1MΩ InsulationresistanceisOK.Thisprocedure
isfinished.
<1MΩ InsulationresistanceisnotOK.Gotothe
nextstep.
2 TurnONthepowerandleaveitonfor6hours.
Result: The compressor will heat up and evaporate any
refrigerantinthecompressor.
3 Measuretheinsulationresistanceagain.
7 Commissioning
7.1 Overview:Commissioning
This chapter describes what you have to do and know to
commissionthesystemafteritisinstalled.
Typicalworkflow
Commissioningtypicallyconsistsofthefollowingstages:
1 Checkingthe"Checklistbeforetestrun".
2 Performingatestrunforthesystem.
7.2 Precautionswhencommissioning
INFORMATION
During the first running period of the unit, the required
powermaybehigherthanstatedonthenameplateofthe
unit.This phenomenoniscaused bythe compressor,that
needs a continuous run time of 50 hours before reaching
smoothoperationandstablepowerconsumption.
NOTICE
Beforestartingupthesystem,theunitMUSTbeenergised
for at least 6 hours. The crankcase heater needs to heat
up the compressor oil to avoid oil shortage and
compressorbreakdownduringstartup.
NOTICE
NEVER operate the unit without thermistors and/or
pressure sensors/switches. Burning of the compressor
mightresult.
NOTICE
Do NOT operate the unit until the refrigerant piping is
complete (when operated this way, the compressor will
break).
NOTICE
Coolingoperation mode.Performthe testrunincooling
operationmodesothatstopvalvesfailingtoopencanbe
detected. Even if the user interface was set to heating
operationmode,theunitwillrunincoolingoperationmode
during23minutes(althoughtheuserinterfacewilldisplay
theheatingicon),andthenautomaticallyswitchtoheating
operationmode.
NOTICE
If you cannot operate the unit in test run, see "7.5 Error
codeswhenperformingatestrun"onpage21.
WARNING
Ifthepanelsontheindoorunitsarenotinstalledyet,make
sureto powerOFF thesystem afterfinishing thetestrun.
To do so, turn OFF operation via the user interface. Do
NOTstopoperationbyturningOFFthecircuitbreakers.
7.3 Checklistbeforetestrun
DoNOToperatethesystembeforethefollowingchecksareOK:
Theindoorunitsareproperlymounted.
Incaseawirelessuserinterfaceisused:Theindoorunit
decorationpanelwithinfraredreceiverisinstalled.
Theoutdoorunitisproperlymounted.
Thefollowingfieldwiringhasbeencarriedoutaccording
tothisdocumentandtheapplicablelegislation:
▪ Betweenthelocalsupplypanelandtheoutdoorunit
▪ Betweentheoutdoorunitandtheindoorunit
ThereareNOmissingphasesorreversedphases.
The system is properly earthed and the earth terminals
aretightened.
The fuses or locally installed protection devices are
installed according to this document, and have not been
bypassed.
The power supply voltage matches the voltage on the
identificationlabeloftheunit.
