Installation Procedure

5 Purgetheairfromthesystemusingvacuumpumpfor

about10minutes.

ꞏ

Closethevalveofthelowpressuresideofmanifold

gaugeclockwise.

ꞏ

Makesurethatpressuregaugeshows-0.1MPa(-76

cmHg)afterabout10minutes.Thisprocedureisvery

importanttoavoidagasleak.

ꞏ

Turnoffthevacuumpump.

ꞏ

Removethehoseofthelowpressuresideofmanifoldgauge.

6 Openthestopvalveofbothliquidandgassides.

7 Mountthevalvestemnutsandtheserviceportcapto

thevalve,andtightenthematthetorqueof183kgfꞏcm

withatorquewrench.

8 Checkforgasleakage.

ꞏ

Atthistime,especiallycheckforgasleakagefromthe3-way

valve’sstemnuts(Aport),andfromtheserviceportcap.

CAUTION

ꞏ

Connecttheindoorandoutdoorunitsusingpipeswith

flaredconnections(notsupplied).Forthelines,use

insulated,unwelded,degreasedanddeoxidizedcopper

pipe,(CuDHPtypetoISO1337orUNIEN12735-1),

suitableforoperatingpressuresofatleast4200kPaand

foraburstpressureofatleast20700kPa.Copperpipefor

hydro-sanitaryapplicationsiscompletelyunsuitable.

ꞏ

Forsizingandlimits(heightdifference,linelength,

max.bends,refrigerantcharge,etc.)see“Connecting

refrigerantpipesection”.

Step 9 Adding refrigerant (R-410A)

ꞏ

Theoutdoorunitisloadedwithsufficientrefrigerantfor

thestandardpiping.Thus,refrigerantmustbeaddedifthe

pipingislengthened.Thisoperationcanonlybeperformed

byaqualifiedrefrigerationspecialist.Todetermine

thequantityofrefrigerantcharge,seeCalculating the

quantity of refrigerant toaddonpage 21.

1 Checkifthestopvalveisclosedcompletely.

2 AC018/024TXQFCH:Chargetherefrigerantthroughthe

serviceportofthegasstopvalve.

AC036/048TXQF**:Chargetherefrigerantthroughthe
