How to Install MR Cool DIY Mini Split Systems: A Step-by-Step Guide

Installing your MR Cool DIY mini split system is easier than you might think. Here’s a detailed, step-by-step process to help you get the job done right:

Step 1: Gather Your Tools and Materials

Before starting the installation process, ensure you have all the necessary tools and materials. Here’s what you’ll need:

• MR Cool DIY mini split kit (includes outdoor unit, indoor unit, mounting brackets, refrigerant lines, and necessary cables)
• Drill with masonry bits (for wall mounting)
• Level
• Wrench set
• Measuring tape
• Refrigerant line insulation
• Power screwdriver
• Safety gear (gloves, goggles)

Step 2: Choose the Right Location for the Units

The first step in your installation process is determining the best locations for both the indoor and outdoor units.

• Outdoor Unit: Choose a location that allows for proper air circulation and is away from obstructions. Ensure it’s at least 2 feet off the ground and not close to any walls or fences that might block airflow.
• Indoor Unit: The indoor unit should be mounted high on the wall for optimal airflow. Avoid areas where furniture or drapes might obstruct air circulation.

Step 3: Install the Mounting Brackets

Next, you’ll need to install the mounting brackets for both the indoor and outdoor units:

• For the indoor unit, mark the spots on the wall where the brackets will go. Use a level to ensure the brackets are perfectly horizontal.
• For the outdoor unit, install the mounting bracket on a sturdy surface that is capable of holding the weight of the unit. This could be a concrete pad or the side of a building.

Step 4: Drill Holes for the Refrigerant Line

Once your brackets are in place, it’s time to drill the hole for the refrigerant line that connects the indoor and outdoor units.

• Use a masonry bit to drill a hole in the wall that will accommodate the refrigerant line. Ensure the hole is slightly larger than the lines to allow for proper insulation.
• The hole should be drilled slightly at an angle downward to allow any condensation to flow outside, preventing water from entering the wall.

Step 5: Mount the Indoor and Outdoor Units

Now it’s time to mount the indoor and outdoor units:

• Indoor Unit: Attach the indoor unit to the wall mounting brackets, ensuring it is level and secure.
• Outdoor Unit: Lift the outdoor unit into place and secure it to the mounting bracket. Make sure it’s stable and positioned for optimal airflow.

Step 6: Connect the Refrigerant Line and Electrical Wires

Now, connect the refrigerant lines and electrical wires between the indoor and outdoor units. Follow the instructions in the MR Cool kit for connecting these lines. Ensure that the refrigerant lines are properly insulated to avoid energy loss and prevent condensation.

• Refrigerant Lines: Carefully connect the lines, ensuring that they are tightly secured to prevent leaks. Use a wrench to tighten the connections.
• Electrical Wires: Connect the electrical wires according to the manufacturer’s instructions. If you’re not comfortable working with electrical components, it’s best to consult a professional.

Step 7: Vacuum the Refrigerant Line

Once the refrigerant lines are connected, you’ll need to vacuum the lines to remove any air. This step is crucial to ensure that the system works efficiently. Use a vacuum pump to remove air from the lines before releasing the refrigerant.

Step 8: Test the System

After everything is connected, it’s time to test the system. Power on both the indoor and outdoor units and ensure they’re running smoothly. Check for any leaks in the refrigerant lines or any unusual noises. The system should start cooling or heating the room immediately.

Troubleshooting Tips

If your MR Cool mini split system isn’t working as expected, here are a few troubleshooting tips to help you resolve the issue:

• Unit Not Cooling or Heating: Ensure that the refrigerant lines are properly connected and that there are no leaks. Double-check that the system was vacuumed properly before refrigerant was added.
• System Blows Warm Air: Check the remote control settings to make sure the system is set to cooling or heating mode. Also, ensure the filter is clean and the indoor unit is not obstructed.
• Outdoor Unit Not Running: Check the power supply and make sure the unit is properly connected to the electrical system. Also, ensure the outdoor unit is not blocked by debris.
• Noise Issues: If you hear unusual noises, check if the unit is properly mounted and leveled. Vibrations could be causing noise if it’s not secured properly.
