Hisense amo4-36u3t25u 36K Multi-zone Outdoor Heat Pump

Product Description

The HISENSE amo4-36u3t25u is a 36,000 BTU/h multi-zone outdoor heat pump unit designed for ductless mini-split systems operating on 208/230 volts with R-454B refrigerant. It supports between one and four connected indoor units and delivers a nominal cooling and heating capacity of 36,000 BTU/h. Efficiency ratings reach SEER2 22 in a non-ducted configuration and HSPF2 10, making this unit a strong performer in residential and light commercial applications. The unit draws 32 amps at full cooling load and carries a maximum fuse size of 50 amps. Licensed HVAC technicians handle procurement, installation, and commissioning of this equipment.

This outdoor condensing unit fits multi-zone ductless mini-split installations where up to four indoor heads are required. Connectable indoor unit capacity ranges from 28,800 to 46,800 BTU/h, providing flexibility across varying room-load scenarios. The operating temperature range extends from 5 degrees F to 125 degrees F in cooling mode and from -13 degrees F to 75 degrees F in heating mode, making it suitable for climates with significant seasonal temperature swings. Typical installations include residential new construction, retrofits without existing ductwork, and light commercial multi-room applications where independent zone control is required.

Compatibility

Designed for use as the outdoor condensing unit in a HISENSE multi-zone ductless mini-split system. Compatible with 1 to 4 HISENSE indoor units with a total combined connectable capacity between 28,800 and 46,800 BTU/h. Refrigerant line connections require a 1/4-inch liquid line and a 3/8-inch suction line. Maximum individual pipe run is 82 feet and maximum total pipe length across all branches is 230 feet.

Installation Notes

Installation must be performed by a licensed HVAC technician certified to handle R-454B refrigerant under applicable EPA Section 608 requirements. Disconnect and lock out all electrical power before making any connections to the unit. Refrigerant line sizing, flaring, and leak testing must comply with the manufacturer installation instructions and local mechanical codes. Do not operate the unit outside the specified voltage range or exceed the maximum fuse size of 50 amps.
