FOUR-WAY VAHU 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).
Due to our policy of continuous product innovation, some specications may change without notication.
