Daikin 3MXM24AVJU8 Multi-zone Heat Pump 24000 Btu/h

Product Description

The DAIKIN 3MXM24AVJU8 is a multi-zone outdoor heat pump condenser rated at 24,000 BTU/h designed to connect up to three indoor air-handling units to a single outdoor unit. Using R-32 refrigerant, this unit is part of Daikin's Standard MXM series and delivers true zoned comfort for multi-room residential and light-commercial applications. Efficiency ratings reach up to 21 SEER2 and 10 HSPF2, making it suitable for projects where energy performance is a design requirement. Licensed HVAC contractors install and commission this system.

The 3MXM24AVJU8 is intended for multi-room installations where individual zone control is required from a single outdoor unit. With three connection ports, the system supports up to three indoor units operating independently, allowing occupants in separate rooms or zones to maintain different temperature setpoints. This configuration is common in residential new construction, additions, and retrofit projects where ductless zoning is preferred over traditional ducted systems. The unit does not include a drain pan heater, which is a noted configuration detail for installations in colder climates.

Installation Notes

Installation must be performed by a licensed HVAC technician holding EPA Section 608 certification, as this system uses refrigerant requiring proper handling. Disconnect all electrical power to the system before making any electrical or refrigerant connections. Line set sizing, refrigerant charge, and system commissioning must follow Daikin's published installation manual and applicable local mechanical codes. Note that this unit does not include a drain pan heater, so evaluate site conditions carefully in regions subject to sustained freezing temperatures.
