Hisense AMW2-18U3SFA Dual-zone Mini-split Condensing Unit 18K

Product Description

The HISENSE AMW2-18U3SFA is a dual-zone mini-split outdoor condensing unit rated at 18,000 BTU/h. It serves as the outdoor compressor and heat exchanger section in a ductless split system, rejecting or absorbing heat to condition two independent indoor zones simultaneously. HVAC technicians install this unit as part of a complete multi-zone ductless system, pairing it with two compatible indoor air handler units. The condensing unit houses the compressor, condenser coil, and fan assembly, and connects to indoor heads via refrigerant line sets.

This condensing unit is suited for residential and light-commercial dual-zone ductless applications where a single outdoor unit must serve two separate indoor spaces. Typical installations include multi-room residential retrofits, additions, and small commercial spaces where running ductwork is impractical. The unit is designed to be mounted outdoors on a pad or bracket and connected to two indoor evaporator units via refrigerant lines and low-voltage control wiring.

Key Features

• Dual-zone configuration supports two independent indoor air handlers from a single outdoor unit
• 18,000 BTU/h total system capacity for multi-room comfort control
• Ductless design eliminates the need for supply and return ductwork
• Outdoor condensing unit houses compressor, condenser coil, and fan in a single cabinet
• Compatible with low-voltage thermostat and control wiring between indoor and outdoor sections

Compatibility

Designed as an OEM-style outdoor condensing unit for dual-zone ductless mini-split systems requiring a combined capacity of 18,000 BTU/h across two indoor zones.

Installation Notes

Installation should be performed by a licensed HVAC technician holding an EPA 608 refrigerant handling certification. Shut off all power at the disconnect before making electrical connections. The outdoor unit must be mounted on a level pad or wall bracket with adequate clearance on all sides per the manufacturer installation manual and local mechanical codes. Refrigerant line sets must be properly sized, leak-tested, and evacuated before charging the system.
