Hisense AS-09UW3SVDDL 9000 Btu Wall Mounted Indoor Unit

Product Description

The HISENSE AS-09UW3SVDDL is a 9000 BTU wall mounted indoor unit designed for ductless mini-split heat pump systems operating on 230 volts. Rated at SEER 18, it delivers efficient heating and cooling performance in a single unit. This indoor air handler mounts high on the wall and connects to a compatible outdoor condensing unit via refrigerant line set and low-voltage control wiring. Installation is typically performed by a licensed HVAC technician with EPA Section 608 certification for refrigerant handling.

This unit is suited for residential and light commercial applications where ductless zoning is required. Common install scenarios include bedrooms, living spaces, additions, sunrooms, server rooms, and other areas where extending ductwork is impractical. Operating on 230 volts, it provides both heating and cooling from a single wall-mounted terminal, making it a practical solution for year-round climate control in single-zone applications.

Key Features

• 9000 BTU heating and cooling capacity for single-zone applications
• SEER 18 efficiency rating reduces operating energy costs
• 230-volt operation for compatibility with standard residential electrical service
• Wall-mounted design keeps floor space clear and delivers direct room airflow
• Integrated heat pump operation provides both heating and cooling modes

Compatibility

Designed as an OEM wall mounted indoor air handler for ductless mini-split systems requiring a 9000 BTU, 230-volt indoor unit with SEER 18 performance.

Installation Notes

Installation must be performed by a licensed HVAC technician holding EPA Section 608 certification for refrigerant work. Before any service or wiring, shut off all power at the disconnect and verify lockout-tagout procedures are followed. The wall mounting bracket must be secured to structural framing capable of supporting the unit weight, and refrigerant line sets must be properly insulated and sealed at all wall penetrations. Always follow local mechanical and electrical codes governing mini-split installations.
