Hisense AUW-18U3SF 18000 Btu Mini Split Outdoor Unit

Product Description

The HISENSE AUW-18U3SF is a single-zone ductless mini split outdoor condensing unit rated at 18,000 BTU/h with heat and cooling capability, operating on 230-volt power. This unit serves as the outdoor half of a low-ambient capable ductless split system, housing the compressor and condenser components that reject or absorb heat depending on the operating mode. It is designed for residential and light-commercial applications and is installed by licensed HVAC technicians as part of a complete single-zone mini split system.

This outdoor unit is suited for single-zone ductless installations where a dedicated condenser is required to condition one indoor space. The 18,000 BTU/h capacity targets mid-size rooms, server rooms, garages, additions, or similar spaces where ducted systems are not practical. The heat-cool functionality allows year-round climate control from a single outdoor unit, eliminating the need for separate heating equipment in moderate climates.

Key Features

• 18,000 BTU/h capacity for single-zone ductless heating and cooling
• 230-volt operation compatible with standard residential electrical service
• Reverse-cycle heat pump design provides both heating and cooling from one outdoor unit
• Single-zone configuration for dedicated room or area climate control
• Low-ambient capable design supports operation in a broader range of outdoor temperature conditions

Compatibility

Designed as an OEM outdoor condensing unit for use in a HISENSE single-zone ductless mini split system. Pair with the corresponding HISENSE indoor air handler rated for 18,000 BTU/h at 230 volts. Consult HISENSE system pairing documentation to confirm the correct matched indoor unit before installation.

Installation Notes

Installation must be performed by a licensed HVAC technician in accordance with local mechanical codes and the manufacturer's installation manual. Shut off all power at the disconnect before making any electrical or refrigerant connections. The outdoor unit must be mounted on a level, vibration-dampening pad with adequate clearance on all sides per manufacturer specifications. Refrigerant line sizing, evacuation, and charge verification should follow industry-standard procedures and applicable EPA Section 608 requirements.
