Daikin 5MXM48AVJU9 — 4 Ton R-32 Five-Port Multi Zone Heat Pump Condenser
The Daikin 5MXM48AVJU9 is a 4 ton, five-port R-32 multi zone heat pump condenser rated at 20 SEER2, 10 EER2, and 9.5 HSPF2, delivering 46,000 BTU/h rated cooling and 48,500 BTU/h rated heating from a single outdoor unit. Five independent refrigerant ports let one condenser serve two to five separate zones, with a total connected indoor capacity of up to 58,000 BTU. This listing covers the outdoor condenser only — wall-mount and Daikin Vista ceiling cassette indoor units, copper and wire kits, and controls are selected below to build the exact system you need. It is intended for whole-home retrofits, additions, in-law suites, offices, and light commercial spaces where individual room control matters more than a single ducted zone.
Is a 4 Ton Five-Zone Condenser the Right Size?
Multi zone sizing is driven by simultaneous load, not by the number of rooms. The 5MXM48AVJU9 is built for properties where five distinct areas need their own setpoint and the combined design load lands in the 46,000 to 48,000 BTU range — typically 2,000 to 2,600 square feet of conditioned space split across bedrooms, living areas, a converted garage, or a detached office. If you only need two or three zones, a smaller multi condenser will run closer to its efficient operating band more of the time.
Because this is a five-port unit, you can connect anywhere from two to five indoor units and mix capacities from 7,000 up to 24,000 BTU per zone, as long as total connected indoor capacity stays at or below 58,000 BTU. Actual performance depends on insulation levels, window area and orientation, ceiling height, air infiltration, occupancy, outdoor design temperature, and how many zones call at the same time. Piping length matters too: the condenser ships pre-charged for 131.25 feet, supports up to 262 feet of total system piping, and allows a 49.25 foot maximum height difference between the outdoor unit and any indoor unit.
Ideal for: Five-zone whole-home retrofits, multi-bedroom homes without ductwork, additions and finished basements, ADUs and guest suites, small office suites, and salons or studios where each room needs independent temperature control.

Recommended zone counts and square footage ranges are general guidelines only. Actual system requirements depend on insulation, window area, ceiling height, infiltration, outdoor design temperature, simultaneous zone demand, and installed piping length.

What ships is the 5MXM48AVJU9 outdoor condenser itself, factory charged with R-32 and ready to accept between two and five indoor units. Each zone needs its own insulated line set and interconnecting wire, which is why a mini split copper and wire kit is offered for every zone in 15, 25, and 50 foot lengths sized to the indoor unit you pick. Ceiling cassette zones also require the BRC1NRV71 wired wall controller, and cold-climate installs can add the optional drain pan heater listed with the options above.

Frequently Asked Questions
Does this listing include the indoor units?
No. The base price covers the 5MXM48AVJU9 outdoor condenser. Indoor units for zones one through five, the copper and wire kit for each zone, and any controls or cold-weather accessories are chosen from the option menus on this page and added to the same order.
How many indoor units can the 5MXM48AVJU9 actually run?
Between two and five. The condenser has five refrigerant ports, and you can populate two, three, four, or all five of them. Unused ports simply stay capped.
What is the maximum total indoor capacity I can connect?
58,000 BTU of combined indoor capacity across all zones. That allowance is what lets you oversize individual rooms — for example five 12,000 BTU heads, or one 24,000 BTU head paired with several smaller ones — while the 4 ton condenser handles the actual simultaneous load.
Can I combine wall-mount heads and ceiling cassettes on the same condenser?
Yes. Wall-mount units and Daikin Vista ceiling cassettes can be mixed on the same 5MXM48AVJU9 as long as total connected capacity stays within limits. Any cassette zone requires the BRC1NRV71 wired wall controller, which can manage up to 16 cassettes on one system.
How cold can this system operate in heating mode?
The 5MXM48AVJU9 carries a heating operating range of 5°F to 75°F and a cooling range of 14°F to 115°F. For installations that see prolonged operation at or below 5°F, or heavy humidity and icing, the optional drain pan heater offered with this product addresses base pan drainage.
How far can the line sets run, and is the unit pre-charged?
The condenser ships pre-charged for 131.25 feet of piping. Total system piping can reach 262 feet, with a maximum 49.25 foot height difference between the outdoor unit and an indoor unit and 24.6 feet between indoor units. Runs beyond the pre-charged length require 0.22 oz of R-32 per additional foot.
What electrical service does the outdoor unit require?
A single 208-230V, single phase, 60 Hz circuit with a minimum circuit ampacity of 38.1 amps and a maximum fuse or breaker size of 40 amps. Indoor units are powered from the outdoor unit through the interconnecting wire in each zone's copper and wire kit.
What refrigerant does this condenser use, and what is the warranty?
This is an R-32 system with a 6.94 lb factory charge; it is not compatible with R-410A indoor units. Daikin provides a 12 year residential limited parts and compressor warranty with online registration, and a 5 year limited parts warranty for commercial applications. Registration terms are detailed in the warranty document above.
