5.3.1 Refrigerantpipingrequirements
INFORMATION
Also read the precautions and requirements in the
"Generalsafetyprecautions"chapter.
Refrigerantpipingmaterial
▪ Pipingmaterial:Phosphoricaciddeoxidisedseamlesscopper.
▪ Pipingtempergradeandthickness:
Outerdiameter
(Ø)
Tempergrade Thickness(t)
(a)
6.4mm(1/4")
9.5mm(3/8")
12.7mm(1/2")
Annealed ≥0.8mm
t
Ø
15.9mm(5/8") Annealed ≥1.0mm
19.1mm(3/4") Halfhard
(a) Dependingontheapplicablelegislationandtheunit's
maximumworkingpressure(see"PSHigh"ontheunit
nameplate),largerpipingthicknessmightberequired.
▪ Flareconnections:Onlyuseannealedmaterial.
Refrigerantpipingdiameter
Usethesamediametersastheconnectionsontheoutdoorunits:
L1liquidpiping Ø9.5mm
L1gaspiping Ø15.9mm
Refrigerantpipinglengthandheightdifference
The piping length and height difference must comply with the
followingrequirements:
H1

Heightdifferencebetweenthehighest
indoorunitandtheoutdoorunit:
H1≤30m
(a) Parenthesisedfigurerepresentstheequivalentlength.
5.3.2 Refrigerantpipinginsulation
▪ Usepolyethylenefoamasinsulationmaterial:
▪ withaheattransferratebetween0.041and0.052W/mK(0.035

5.4 Preparingelectricalwiring
5.4.1 Aboutpreparingelectricalwiring
INFORMATION
Also read the precautions and requirements in the
"Generalsafetyprecautions"chapter.
INFORMATION
Also read "6.7.5 Specifications of standard wiring
components"onpage18.
WARNING
▪ If the power supply has a missing or wrong Nphase,
equipmentmightbreakdown.
▪ Establish proper earthing. Do NOT earth the unit to a
utility pipe, surge absorber, or telephone earth.
Incompleteearthingmaycauseelectricalshock.
▪ Installtherequiredfusesorcircuitbreakers.
▪ Secure the electrical wiring with cable ties so that the
cables do NOT come in contact with sharp edges or
piping,particularlyonthehighpressureside.
▪ Do NOT use taped wires, stranded conductor wires,
extension cords, or connections from a star system.
Theycancauseoverheating,electricalshockorfire.
▪ DoNOTinstall a phase advancingcapacitor,because
this unit is equipped with an inverter. A phase
advancing capacitor will reduce performance and may
causeaccidents.
WARNING
▪ All wiring must be performed by an authorized
electrician and must comply with the applicable
legislation.
▪ Makeelectricalconnectionstothefixedwiring.
▪ All components procured on the site and all electrical
construction must comply with the applicable
legislation.
WARNING
ALWAYSusemulticorecableforpowersupplycables.
