Daikin 4MXM36AVJU8 Multi-split 4-port Heat Pump 3 Ton

Product Description

The DAIKIN 4MXM36AVJU8 is a 3-ton multi-split outdoor heat pump unit designed for multi-zone residential and light commercial applications. Part of the Daikin Standard MXM series, this R-32 refrigerant system connects up to four indoor air handlers to a single outdoor unit, delivering true zoned temperature control across multiple rooms. The unit achieves up to 21 SEER2 and 10 HSPF2 efficiency ratings, making it a strong choice where energy performance and individual room comfort are both priorities. Licensed HVAC technicians perform installation and commissioning.

The 4MXM36AVJU8 suits multi-room residential applications and smaller commercial spaces where separate zone control is required without running multiple outdoor units. Connecting up to four indoor units to one outdoor condenser reduces rooftop or ground-level equipment footprint while maintaining independent room-by-room temperature management. This model is configured without a drain pan heater, which should be confirmed against the installation site climate requirements before specifying. It is appropriate for new construction and retrofit multi-zone projects.

Installation Notes

Installation must be performed by an EPA 608-certified HVAC technician familiar with multi-split inverter systems and R-32 refrigerant handling procedures. Shut down all electrical power to the system at the disconnect before making any electrical or refrigerant connections. R-32 is an A2L mildly flammable refrigerant and requires compliance with applicable local codes and manufacturer handling guidelines. Review Daikin MXM installation documentation for line set sizing, charge verification, and commissioning procedures before startup.
