Daikin 2MXTH18AVJU9 — 2-Zone AURORA Multi-Zone Condenser (18,000 BTU)
The Daikin 2MXTH18AVJU9 is a compact, high-efficiency 2-zone multi-split heat pump condenser from Daikin’s AURORA/MXTH family, engineered to deliver reliable year-round heating and cooling for two independently controlled indoor units. Designed for versatility and quiet operation, this condenser uses R-32 refrigerant and an inverter compressor to provide precise temperature control, and simplified zoning for homes or light commercial spaces.
- Model: 2MXTH18AVJU9
- Nominal Capacity: 18,000 BTU (1.5 ton)
- Zones / Indoor Units: 2 (requires exactly two indoor units)
- Refrigerant: R-32 (lower global warming potential)
- Drain Pan Heater: Included (model variant includes drain pan heater for cold-climate protection)
Key benefits: The 2MXTH18AVJU9 brings Daikin’s proven reliability and inverter technology to multi-zone applications. Owners get individual room control, improved part-load efficiency for lower energy bills, quieter outdoor operation, and reduced refrigerant charge compared with older refrigerants. The included drain pan heater improves outdoor durability in freezing climates, and the R-32 refrigerant helps lower environmental impact.
- Zoning flexibility: Mix and match compatible Daikin indoor units (wall-mounted, cassette or small ducted units) — total combined indoor capacity must not exceed the maximum connected capacity for the outdoor unit.
- Part-load savings: Variable speed inverter operation typically yields substantial efficiency gains at typical operating conditions versus fixed-speed systems.
- Quiet design: Engineered to minimize vibration and airborne noise from the outdoor unit.
- Durability features: Corrosion-resistant cabinet design and drain pan heater.
- Drain Pan:Prevents freeze/thaw drainage issues in cold climates, as well as preventing the growth of potential mold.
Installation & service notes: This condenser is intended to be installed by qualified HVAC contractors
- Electrical: 208/230V single phase supply required — confirm breaker size and supply wiring per local code and Daikin installation instructions.
- Piping: Use approved line set sizing for selected indoor units; follow Daikin piping diagrams and vacuum/brazing procedures.
- Commissioning: Verify system communication to each indoor unit, perform leak checks, and follow manufacturer startup sequence for optimal performance.
Warranty & support: Backed by Daikin’s 12-year limited parts warranty and supported through Daikin’s distributor and contractor network. Refer to the product manual and your reseller for specific warranty terms applicable to your region and installer registration requirements.
