30mAINSTALLATION MANUAL FOR OUTDOOR UNIT24(6) Additional charge of refrigerant5. Electric wiringOutdoor unit is precharged at a factory for the piping length up to 5m. Additional charge is not requiredup to 5m.Notes (i) Basic refrigerant charge amount means refrigerant amount when refrigerant piping length is 5m.(ii) When the refrigerant piping length exceeds the length that additional refrigerant charge is notrequired, charge additional refrigerant based on to the calculated amount of refrigerant per unitpiping length.Example of additional charge amount calculationCalculate the additional charge amount when the piping length is 25 m.Additional charge amount of refrigerant =0.70kg(Calculate the amount in any case.)WARNINGDANGER OF BODILY INJURY OR DEATHTURN OFF ELECTRIC POWER AT CIRCUIT BREAKER OR POWER SOURCE BEFOREMAKING ANY ELECTRIC CONNECTIONS. GROUND CONNECTIONS MUST BECOMPLETED BEFORE MAKING LINE VOLTAGE CONNECTIONS.(1) Selection of size of power supply and interconnecting wires.Precautions for Electric wiringElectric wiring work should be conducted only by authorized personnel.Do not connect more than three wires to the terminal block. Always use round type crimped terminallugs with insulated grip on the ends of the wires.Use copper conductor only.Select wire sizes and circuit protection from table below. (This table shows 20 m length wires withless than 2% voltage drop.)(25 - 5 ) x 0.06 = 1.2Additional charge amount (kg)Additional charge amount per 1m (kg/m)Length that additional refrigerant charge is not required (m)Total length of the piping (one way) (m)HeatpumpLength thatadditionalcharge is notrequiredMaximumpipinglengthAdditionalchargeamount (ii)per meterBasicrefrigerantchargeamount (i)Factory charge amountof refrigerantOutdoor unit Indoor unitItemModel3.44 3.52 0 0.06 5m 50m(v)(viii)2.32 2.40 0 0.06 5m (vii)(viii) 30m36,42 series24,28 seriesItemModel Phase3Switch breaker(A)Circuit breakerOvercurrent protectorrated capacity (A)Power sourcewire size(minimum)30 20 2.5mm21 40 26 4.0mm236,42 series, 28 series(380-400V,3N~,50Hz)24,28,36 series (1PH,220-230V~, 50Hz)SwitchbreakerEarth leakage breakerLeakcurrent30 30mA40
