Correction of cooling and heating capacities according tothe connecting pipe length.The data of cooling capacities (marked on the name plate)are based on 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 10 metres.APPLICABLE FOR ALL MODELSBefore shipment, this air conditioner is filled with the ratedamount of refrigerant subject to 10m piping length.
