ERQ100~140A7V1BInverter condensing unit4PW51321-1Installation manual10See figure 6.To avoid compressor breakdown. Do not charge the refrigerantmore than the specified amount.■ This outdoor unit is factory charged with refrigerant anddepending on pipe sizes and pipe lengths some systems requireadditional charging of refrigerant. See "How to calculate theadditional refrigerant to be charged" on page 10.■ In case re-charge is required, refer to the nameplate of the unit.The nameplate states the type of refrigerant and necessaryamount.Installation limitationsHow to calculate the additional refrigerant to be chargedAdditional refrigerant to be charged R (kg)R should be rounded off in units of 0.1 kgR=(Total length (m) of liquid piping size at Ø9.5)x0.054Determine the weight of refrigerant to be charged additionallyreferring to the item "Additional refrigerant charge" in "How tocalculate the additional refrigerant to be charged" on page 10 and fillin the amount in the "Additional refrigerant charge label" attached tothe unit.Precautions when adding R410ABe sure to charge the specified amount of refrigerant in liquid state tothe liquid pipe.Since this refrigerant is a mixed refrigerant, adding it in gas form maycause the refrigerant composition to change, preventing normaloperation.■ Before charging, check whether the refrigerant cylinder isequipped with a siphon tube or not.10.1.
