Hisense ao-09u3r25e 9K Outdoor Heat Pump Single-zone Mini-split

Product Description

The HISENSE ao-09u3r25e is a single-zone outdoor heat pump condensing unit designed for ductless mini-split systems. Rated at 9,000 BTU/h for both cooling and heating, it operates on 208/230V power and uses R-32 refrigerant. With a SEER2 rating of 22.5 and an HSPF2 of 9.0, it delivers strong efficiency for residential and light-commercial applications. The unit draws 3.4 amps during cooling and is protected by a maximum 15-amp fuse. HVAC technicians pair this outdoor condenser with a compatible single-zone indoor air handler to complete the system. Its compact cabinet measures 28.125 inches wide, 21.25 inches tall, and 9.5 inches deep, making it suitable for installations with limited clearance.

This outdoor unit is intended for single-zone ductless mini-split installations in residential and small commercial settings. It supports cooling operation across a wide ambient range of 5 to 118 degrees F and heating down to -5 degrees F, making it viable in cold-climate applications. The unit connects to one indoor air handler with a nominal capacity of 9,000 BTU/h. Liquid line connection is 0.25 inches and suction fitting is 0.375 inches, with a maximum total pipe run of 65.59 feet. A licensed HVAC technician should perform installation and refrigerant handling in accordance with local codes and EPA Section 608 requirements.
