Correction of cooling and heating capacities according tothe connecting pipe length.The data of cooling capacities (marked on the name plate)are based on 7.5 metres connecting pipe and horizontalinstallation.(Cooling)Equivalent Length = actual pipe length +number of elbow x ELE + number of oiltrap x ELOELE: equivalent length of elbow.ELO: equivalent length of oil trap.10.2. REFRIGERANT ADDITIONALCHARGE•••• The piping length exceeds 30 metres.APPLICABLE FOR ALL MODELSBefore shipment, this air conditioner is filled with the ratedamount of refrigerant subject to 30m piping length. (Therated amount of refrigerant is indicated on the name plate.)But when the piping length exceeds 30m, additional chargeis required according to the following table.For other pipe length of other installation multiplyby the following correction factor to determine therevised cooling capacity.(Heating)Outer diameter of gasside pipe mm (inch)9.52 0.1812.7 (1/2) 0.2015.88 (5/8) 0.2519.05 (3/4) 0.35Model Ref.
