1 . Outdoor unit 1. Unit selection (based on cooling load) 11. Indoor unit selection Select the indoor unit based upon cooling load and unit capacity. (The indoor unit capacity should larger than the load.) Indoor units can be of different capacities, however total capacity must be checked against the outdoor unit capacity table. 12. Outdoor unit selection Allowable combinations are described on the indoor unit combination total capacity index table. For a standard indoor unit and outdoor unit combination, select the nearest value of the total indoor unit capacity index that is less than a 100% outdoor unit combination capacity index. Indoor unit combination total capacity index outdoor unit 130% 120% indoor unit combination rate 110% 100% 90% % % 60% % RVMH060GBM RVMH100GAM RVMH100FAM (ISO) The system enables the connection of indoor units with a total capacity of between to 130% of that of the corresponding outdoor unit but where this capacity ratio exceeds 100% then the actual capacity of each indoor unit will fall a little short of its individual rated capacity when all the units are operated simultaneously. (Except Middle East models) Indoor unit capacity index Hz Unit size capacity index Hz Unit size capacity index

2 13. Real function data (1) Select the exact capacity according to outdoor unit model and combination rate using outdoor unit capacity table. According to given indoor and outdoor, find outdoor unit capacity and power input using the table. Each indoor unit capacity (power input) is calculated as follow. IUC=OUC x INX/TNX IUC: Each indoor unit capacity (power input) OUC: Outdoor unit capacity (power input) INX: Each indoor unit capacity index TNX: Total capacity index (2) If the capacity is smaller than the load, change unit to a larger capacity indoor unit and repeat the selection process. 3
