Table 34: Multi F Standard Wall-Mounted Indoor Units Heating Capacity Table.
TC = Total Capacity (kBtu/h).
Nominal capacity as rated 0 ft. above sea level and a 0 ft. level difference between outdoor and indoor
units. Corresponding refrigerant piping length is accordance with standard length of each outdoor unit.
Nominal heating capacity rating obtained with air entering the indoor unit at 70ºF dry bulb (DB) and
60ºF wet bulb (WB), and outdoor ambient conditions of 47ºF dry bulb (DB) and 43ºF wet bulb (WB).
