Go to the next step.3 Evacuate for at least 2 hours to a pressure on the manifold of−0.1 MPa (−1 bar).4 After turning OFF the pump, check the pressure for at least1 hour.5 If you do NOT reach the target vacuum or cannot maintain thevacuum for 1 hour, do the following:▪ Check for leaks again.▪ Perform vacuum drying again.NOTICEBe sure to open the gas stop valve after piping installationand vacuuming. Running the system with the valve closed,the compressor may break down.4.5 Charging refrigerant4.5.1 To determine the additional refrigerantamountIf the total liquidpiping length is…Then…≤10 m Do NOT add additional refrigerant.>10 m R=(total length (m) of liquidpiping–10 m)×0.020R=Additional charge (kg)(rounded in unitsof 0.1 kg)INFORMATIONPiping length is the one way length of liquid piping.4.5.2 To charge additional refrigerantWARNING▪ Only use R32 as refrigerant. Other substances maycause explosions and accidents.▪ R32 contains fluorinated greenhouse gases. Its globalwarming potential (GWP) value is 675. Do NOT ventthese gases into the atmosphere.▪ When charging refrigerant, always use protectivegloves and safety glasses.Prerequisite: Before charging refrigerant, make sure the refrigerantpiping is connected and checked (leak test and vacuum drying).1 Connect the refrigerant cylinder to the service port.2 Charge the additional refrigerant amount.3 Open the gas stop valve.4.5.3 To fix the fluorinated greenhouse gaseslabel1 Fill in the label as follows:bContains fluorinated greenhouse gases21 1122 kgtCO2eqGWP × kg1000==+kg=kg=GWP: XXXRXXXaf cdea If a multilingual fluorinated greenhouse gases label isdelivered with the unit (see accessories), peel off theapplicable language and stick it on top of a.b Factory refrigerant charge: see unit name platec Additional refrigerant amount chargedd Total refrigerant chargee Greenhouse gas emissions of the total refrigerant chargeexpressed as tonnes CO2-equivalentf GWP = Global warming potentialNOTICEIn Europe, the greenhouse gas emissions of the totalrefrigerant charge in the system (expressed as tonnesCO2-equivalent) is used to determine the maintenanceintervals. Follow the applicable legislation.Formula to calculate the greenhouse gas emissions:GWP value of the refrigerant × Total refrigerant charge [inkg] / 10002 Fix the label on the inside of the outdoor unit near the gas andliquid stop valves.4.6 Connecting the electrical wiringDANGER: RISK OF ELECTROCUTIONWARNINGALWAYS use multicore cable for power supply cables.4.6.1 About electrical complianceOnly for ERGA04~08DAV3 (not for ERGA06+08DAV3A)Equipment complying with EN/IEC 61000‑3‑12 (European/International Technical Standard setting the limits for harmoniccurrents produced by equipment connected to public low-voltagesystems with input current >16 A and ≤75 A per phase.).4.6.2 Specifications of standard wiringcomponentsComponent ERGA04~08DAV3 ERGA06+08DAV3APowersupplycableMCA(a) 24.0 A 15.7 AVoltage 230 VPhase 1~Frequency 50 HzWire sizes Must comply with applicable legislationInterconnection cable Minimum cable section of 1.5 mm² andapplicable for 230 VRecommended field fuse 25 A 16 AEarth leakage circuitbreakerMust comply with applicable legislation(a) MCA=Minimum circuit ampacity.
