The DIY system includes Quick Connect lines that are pre-charged with eco-friendly R-454B refrigerant.

The MRCOOL DIY Multi-Zone 18,000 BTU 23.9 SEER2 3 Zone Ductless Heat Pump Split System - 6K + 6K + 9K can cool through the Summer, heat through the Winter, and dehumidify through the wet seasons. Plus, you can quickly check the temperature of each room in your home from the easy to read digital display or from the MRCOOL Smart Controller mobile app. The display on the front of each indoor air handler unit can also display troubleshooting codes and alerts, so you are always aware of any issues with your system. Operate each unit wirelessly with either the included remote or with the MRCOOL Smart Controller app for Apple or Android devices. You also have the ability to control your mini-split unit with Amazon Alexa or Google Home.

The three MRCOOL DIY Multi-Zone air handlers included in this set provide directional control of the heated or cooled air. This distributes the air evenly so everyone in the room can stay comfortable. If you are in a situation that requires forced cooling, you can set your MRCOOL DIY System to manual with the button located on the right side of the unit under the front panel. In this emergency operation mode, you can test the cooling operation of your unit after installation or to complete a maintenance task.

In auto mode, each unit provides air for your home at your desired comfort level. Set your desired temperature, and the HVAC unit will determine how much heat or air conditioning is needed. You can also set this system to a drying function, which will continue to control the space’s air temperature while dehumidifying.

Use the sleep mode at night to save money on your utilities bills and use less energy. Sleep mode operates in an 8 hour window once turned on.

Limit your energy usage and save money on your utility bill by using the system’s timer function. If your system begins to run low on refrigerant, an alert will appear on the easy-to-read display on the front of each air handler, letting you know there may be a leak. If you desire to keep a room quiet and minimize lighted alerts, you can mute each indoor unit. By muting the system, the buzzer for alerts will not sound and the LED lit display will turn off. Should the unfortunate event of a power outage occur, the MrCool system will automatically shut off and then back on with the same settings once power returns.

Any troubleshooting codes will appear on the front display and the user manual contains an index for common codes.

Squeaky ball
Color: Large Set of 4
Perfect squeaky ball. Dogs love them. I love that they're durable and their thickness aids their durability. My Great Dane will play alone for hours with a ball.

Excellent Pee Pad Holder for Indoor Dog Training
This pee pad holder is very practical and works great for indoor potty training. The non-slip silicone material stays firmly in place and doesn’t slide around on the floor. The raised edges do an excellent job preventing leaks and protecting my floors. The magnetic clips hold the pad securely, even when my dog moves around a lot. Overall, it’s well made, easy to clean, and makes puppy training much less messy.

Best choice
This pee pad holder has been a lifesaver for indoor puppy training. The 24" x 24" size fits standard pads perfectly, and the non-slip silicone keeps everything in place. The raised, leak-proof edge gives great floor protection, while the four magnetic clips securely hold pads without tearing. It’s easy to clean, durable, and looks neat at home. A practical, well-designed tray that makes potty training cleaner, easier, and far less stressful. Highly recommended for apartment owners and busy pet parents.
