Reactive Temperature Monitoring
Daikin ductless systems do not require any setting changes to keep your home comfortable on a hot or cool day. Once you set a temperature for the system to maintain, the system automatically adjusts output levels according to environmental conditions.

Inverter Technology Prevents Temperature Fluctuation
The RMXS48LVJU unit features inverter technology. This works together with the expansion valve to adjust coolant flow and compressor speed to match indoor conditions. This results in less dramatic temperature swings and a more comfortable home.

Low Ambient Cooling and Heating
MXS condensers will continue to operate optimally even in colder climates. With an operational cooling range down to 14°F, and a heating range down to 5°F, the MXS can provide heating or cooling in any enviroment.

Whisper Quiet Operation
Daikin ductless units are engineered from the ground up for impressively quiet operation. The solidness of the units construction works together with quiet motor operation to make the units as unobtrusive as possible to its surrounding environment.

"Intelligent Eye" Energy Saving Mode
Daikin ductless indoor units have built in motion sensing technology. If no movement has been detected for 20 minutes, the system enters energy saving mode. Upon sensing motion, the system switches back to full operation.

Built-In Advanced Filtration System
Daikin mini splits do more for your home's comfort level than control its temperature. An advanced microbial filtration system is installed in the indoor unit, allowing the mini split to purify your home's air as well as heating or cooling it.

Recommended line set sizes for indoor unit connectivity:
FTXS15LVJU: 1/4" x 1/2" Line Set
FTXS18LVJU: 1/4" x 1/2" Line Set (Qty 2)

 This product requires the following accessories for installation:

Line Set - This double insulated tubing transfers refrigerant efficiently between your outdoor condenser and indoor units.

Drain Tubing - Drain tubing facilitates the reliable and effective removal of condensate from your system. It connects your indoor units to drain locations of your choosing.

Disconnect Box & Electrical Whip Kit - The Disconnect Box & Whip Kit provides a safe and simple way to connect your outdoor condenser to your fuse box.

Connecting Wire - This durable, insulated wire provides power to your indoor units from your outdoor condenser.

Base Pan Heater - The base pan heater prevents ice from building up on the outdoor unit. Excessive ice build will lead to performance issues and could damage your unit.

Outdoor Condenser Plastic Pad or Wall Bracket - We recommend outdoor condensers should not be placed directly on the ground. An outdoor condenser pad or wall bracket will provide a stable way to mount your condenser free from obstructions and debris.
Adding these accessories to your order will provide a complete, ready-to-install mini split system.
