Vacuum first, then charge the liquid refrigerant into air conditioneraccording to the amount marked on the name plate.Please do not let other cooling medium, except specified one (R410A), or air●enter into the cooling circulation system. Otherwise, there will be abnormalhigh pressure in the system casuing damage and possibly personal injuries.1 Power Source Installation2 Cutting and Flaring Work of PipingFlare tooling die 1.Cut pipe 2.Remove burs3.Insert the flare nutCAUTIONFlare tool for R410A Conventional flare toolClutch-type clutch-type(Rigid-type) Wing-nut type (Imperial-type)A 0~0.5mm 1.0~1.5mm 1.5~2.0mmrth leakage breaker (GFCI).4.Flare pipeLean Damage of flare Crack Partial Too outsideCorrect Incorrect3 On DrainageIt becomeshigh midway.The gap with theground is too small.There is the badsmell from a ditchIt waves.The end is imm-ersed in water.Please install the drain hose so as to be downward slope without fail.Please don’t do the drainage as shown below.●●Please pour water in the drain pan of the indoor unit, and● is carried out surely to outdoor.In case that the attached drain hose is in a room, please● apply heat insulation toLess than5cmconfirm that drainageit without fail.Check Items for Test RunPut check mark in boxesGas leak from pipeconnecting ?Heat insulation ofAre the connecting wirings of indoor and outdoor firmlyIs the connecting wiring of indoor and outdoor firmly fixed?Is drainage securely carried out?Is the ground wire securely connected?Is the indoor unit securely fixed?Is power source voltage abided by the code?Is there any noise?Is the lamp normally lighting?Are cooling and heating (when in heat pump) performed normally?Is the operation of room temperature regulator normal?Please kindly explain to our customers how to operatethrough the instruction manual.Check for Installation and Test Run■inserted to the terminal block?■11+2= kgR410A2 kg2=1= BCDF EkgAThis product contains fluorinated greenhouse gases covered bythe Kyoto Protocol.
