If the refrigerant leaks in theroom and comes in contact with fire from a burner, aheater, or a cooker, this may result in fire, or the formationof a harmful gas.Turn off any combustible heating devices, ventilate theroom, and contact the dealer where you purchased theunit.Do NOT use the unit until a service person confirms thatthe part from which the refrigerant leaked has beenrepaired.4.5.3 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 0.01 kg)INFORMATIONPiping length is the one-way length of liquid piping.4.5.4 To determine the complete rechargeamountINFORMATIONIf a complete recharge is necessary, the total refrigerantcharge is: the factory refrigerant charge (see unit nameplate) + the determined additional amount.4.5.5 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.4.5.6 To fix the fluorinated greenhouse gaseslabel1 Fill in the label as follows:bContains fluorinated greenhouse gases21 1122 kgtCO2 eqGWP × 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 Quantity of fluorinated greenhouse gases of the totalrefrigerant charge expressed as tonnes CO2 equivalent.f GWP = Global warming potentialNOTICEApplicable legislation on fluorinated greenhouse gasesrequires that the refrigerant charge of the unit is indicatedboth in weight and CO2 equivalent.Formula to calculate the quantity in CO2 equivalenttonnes: GWP value of the refrigerant × total refrigerantcharge [in kg] / 1000Use the GWP value mentioned on the refrigerant chargelabel. That GWP is based on the current legislation onfluorinated greenhouse gases.
