Product Overview
Now with heating capabilities down to -5°F, Panasonic Mini-Splits are a great option for much of the US.
Panasonic's 3 zone Mini Split System offers you the advantage of a single system that is connectable for up to 3 indoor units. That is from 2 to 3 individual temperature controlled rooms without duct work! Panasonic's innovative technology enables high energy saving performance with SEER ratings of 22 and an HSPF rating of 10.5 - for more efficient operation than ever before. Because each room operates independently, you can customize your BTUs for each space. Panasonic offers Indoor units ranging from 5,500 BTUs for smaller rooms, up to 18,000 BTUs for larger rooms. Connectivity capacities of this unit is a minimum of 15,300 BTUs with a maximum of 30,600 BTUs. This system is Energy Star Qualified when installed with non-ducted indoor units.
With the Panasonic System 3 Multi-Zone, long piping length flexibility is also featured. The maximum total length is 164 feet with a maximum length of 82 feet for a single indoor unit. The maximum height difference is 49 feet. With the flexibility of long piping lengths, this system can be installed in virtually any building design.
Of course the system also includes Panasonic's inverter technology - providing optimum power control and extremely efficient operation by changing the power supply frequency. The result is speedy, flexible operation that uses less electricity. The inverter constantly adjusts compressor rotation speed to provide optimum performance at all times. Once the set temperature is achieved, the inverter air conditioner continues to operate with minimum power.
And talk about reliability, with its low ambient heating capability, you will never be cold - heating is possible even if the temperature outside falls as low as -5°F.
The CU-3E19RBU-5 Tri-Zone is rated for 19,000 BTU Cooling Capacity and must be connected to at least two / maximum three indoor units. The combined BTU ratings of the units chosen can total up to a maximum connected BTU rating of 30,600 BTUs.

Line Sets

Mini Split Line Sets - Line sets are a requirement when installing a mini split system. They are the connection between the outdoor unit and the indoor units of your system. Every indoor unit needs to be connected directly to the outdoor unit with its own line set. Most Mini Split Line Sets come with flared connectors attached and are ready to install. Our line sets are offered with and without control wire and are available in various connection sizes and lengths to meet your installation needs. The line set shown in the photo does not include the control wire.

Above is an example of a 3-zone installation
At least two indoor units MUST be connected to the CU-3E19RBU-5 compressor. Nominal Capacity range of connectable indoor units must be from 15,500 BTUs ~ 30,700 BTUs. Please note that a 2 unit configuration CANNOT include a combination of two CS-ME7RKUA units or less as this would be less than the minimum of 15,360 BTUs of nominal capacity. Please double check your configurations before placing your order. Feel free to call Customer Service at 877-847-0050 for ANY questions regarding the purchase of this unit.
