Step-by-Step Installation Guide for MrCool DIY Mini Split System

Step 1: Choose the Right Location

The placement of both your indoor and outdoor units is crucial for optimal performance and efficiency.

• Indoor Unit: Install this unit on an exterior wall, ideally in a central location to provide balanced air distribution throughout the room. Avoid placing it near doors or windows to prevent temperature fluctuations.
• Outdoor Unit: Place the outdoor unit on a stable, level surface to reduce vibration. Common options include a concrete pad or sturdy mounting brackets. Ensure it’s located in a shaded area for maximum efficiency and has at least 24 inches of space around it to allow for proper airflow.

Step 2: Mount the Indoor Unit

The indoor unit needs to be securely attached to a wall bracket.

• Using the Mounting Template: Use the provided wall mounting template to locate the precise spots for screw holes and the through-wall hole, making sure your bracket and unit will align perfectly. This template takes the guesswork out of measuring and ensures a clean, easy installation.
• Attach the Bracket: Measure and attach the mounting bracket at the desired height on your wall. The unit should be level to prevent drainage issues and firmly attached to the wall for stability.
• Drill a Hole for the Conduit: Using a drill, create a small hole (typically around 3.5 inches in diameter) through the wall near the mounting bracket. This hole will allow the conduit with refrigerant lines, power cable, and drain hose to pass through to the outdoor unit.

Step 3: Install the Outdoor Unit

The outdoor unit placement is critical for the longevity and efficiency of your MrCool DIY Mini Split system.

• Set on a Stable Surface: Position the outdoor unit on a concrete pad or secure brackets to keep it stable and level.
• Protect Against Elements: If you’re in an area with extreme weather, consider additional protection, like a condenser cover, to prolong the unit’s lifespan.

Step 4: Connect the Refrigerant Lines

One of the key benefits of the MrCool DIY Mini Split is its pre-charged refrigerant lines, which eliminate the need for specialized tools or a licensed HVAC technician.

• Run the Lines: Carefully feed the conduit (refrigerant lines, power cable, and drain hose) from the indoor unit through the hole in the wall to the outdoor unit.
• Attach the Lines: Attach the refrigerant lines to the connectors on both the indoor and outdoor units. MrCool provides clear, labeled fittings that make this process straightforward.

Step 5: Make Electrical Connections

Connecting the electrical components requires attention to detail and strict adherence to safety guidelines.

• Follow the Manual: MrCool’s instructions provide detailed steps for wiring the indoor and outdoor units. Typically, you’ll connect the power supply to the outdoor unit, which then connects to the indoor unit through a communication wire.
• Safety First: If you're uncertain about electrical work, consider hiring an electrician for this step. Safety is paramount, especially when dealing with high-voltage connections.

Step 6: Secure and Seal Connections

Properly securing and sealing the connections between the units is essential for maintaining efficiency and preventing leaks.

• Seal the Hole in the Wall: Use weatherproof sealant around the hole where the conduit exits your home to prevent drafts and water infiltration.
• Check Connections: Ensure all connections are tight and secure. Loose connections can lead to refrigerant leaks or reduced efficiency.

Step 7: Test Your System

Once everything is connected, it’s time to power on and test your MrCool DIY Mini Split.

• Turn on the Power: Flip the switch on your electrical panel to supply power to the unit.
• Test Modes: Use the remote or control panel to test the cooling, heating, and fan modes. Make sure each mode works properly, and check that the air handler is blowing air at the set temperature.
• Check for Efficiency: Observe the system’s operation for a few hours to ensure it’s functioning smoothly and efficiently.
