MULTI-ZONE MRCOOL DIY 36K BTU 4-ZONE MINI-SPLIT - AN AC SYSTEM YOU CAN INSTALL YOURSELF!
Use this multi-zone system to heat and cool four different areas in your home or office. The MrCool DIY 36k BTU 21.5 SEER 4-Zone Ductless Heat Pump Split System - 9k+9k+12k+12k is one of the only multi-zone systems available that you can install yourself without an HVAC professional. The outdoor heat pump powering this system has a heating capacity of up to 36,000 BTU and is extremely efficient with a 21.5 SEER rating.
The two 9,000 BTU air handlers distribute heated and cooled air efficiently in spaces up to around 400 square feet. The two 12,000 BTU air handlers work best in rooms up to 550 square feet.
The MrCool DIY Ductless Split System is a heat pump, meaning that when the appliance heats your space, the appliance is reversing the air conditioning process and pulling heat indoors from outside.
This MrCool DIY 36k BTU 21.5 SEER 4-Zone Ductless Heat Pump Split System - 9k+9k+12k+12k can be installed without special tools or training. It can be installed completely by yourself. The Quick Connect line set makes this straightforward installation possible thanks to the pre-charged eco-friendly refrigerant in the line.
Each of the four air handlers in this MrCool DIY 36k BTU 21.5 SEER 4-Zone Ductless Heat Pump Split System - 9k+9k+12k+12k are designed to evenly distribute temperature-controlled air throughout your home or office, and they all offer several operating modes. The simplest operating option is Auto Mode. Set your desired temperature and let the appliance do the rest.
In Sleep Mode, save money while you sleep. The MrCool split system will drop when heating and rise when cooling by 2°F in the first two hours of sleep mode operation. For the next six hours, the unit continues to run at this more moderate temperature so you can sleep comfortably without breaking the bank.
The temperature of the room is displayed using LED lights on the front of each air handler and can also be found using the MrCool Smart Controller app, which is available on iOS and Android devices.
To set up wireless connection to an air handler, insert the included USB device under the front panel. Options for controlling your unit wirelessly include the air handler’s remote, the MrCool Smart Controller app, Amazon Alexa, and Google Assistant.
Enhance your heating and cooling experience with quality features on the MrCool DIY 36k BTU 21.5 SEER 4-Zone Ductless Heat Pump Split System - 9k+9k+12k+12k. You can easily control energy usage to save money with the timer and turn off the buzzer alerts and LED display with the mute function.
Reduce the risk of mildew in the air handlers by using the anti-mildew function, which keeps the unit running for 10 additional minutes after being shut off with a low airflow to dry out the unit and prevent mildew from forming. If the power goes out, your unit will automatically resume operation with the same settings once the power returns, so you don’t have to worry about resetting your system.
To clean MrCool DIY 36k BTU 21.5 SEER 4-Zone Ductless Heat Pump Split System - 9k+9k+12k+12k, simply wipe each appliance with a dry or damp cloth. No special cleaning solution needed. You can maintain your MrCool DIY Multi-Zone Split System using the troubleshooting codes that appear on the front display of the air handlers when an issue arises. The codes will range from low refrigerant alerts to reminders to clean or replace air filters.
