• Wall-mounting bracket
• Concrete anchors
• Level
• Drill
• Screwdriver
• Wire stripper
• Voltage tester

2. Choose the Optimal Location

Selecting the ideal location for the indoor and outdoor units is crucial for optimal performance.

• Indoor Unit: Install it on an interior wall, approximately 6-8 feet above the floor. Ensure there are no obstructions blocking airflow.
• Outdoor Unit: Place it on a level surface, away from direct sunlight and potential wind interference. Maintain a minimum clearance of 2 feet around the unit.

3. Install the Wall-Mounting Bracket

• Mark the mounting location on the wall, using the provided template.
• Drill pilot holes and insert the concrete anchors.
• Securely mount the bracket to the wall using the provided bolts.

4. Mount the Indoor Unit

• Carefully lift the indoor unit onto the wall-mounted bracket.
• Align the unit and secure it with the provided screws.
• Ensure the unit is level and securely attached.

5. Connect the Refrigerant Lineset

• Cut the refrigerant lineset to the appropriate length, ensuring no kinks or bends.
• Flare the ends of the lineset using a flaring tool.
• Connect the lineset to the indoor and outdoor units, tightening the flare nuts securely.

6. Run the Electrical Wiring

• Install the electrical conduit from the indoor unit to the outdoor unit.
• Run the electrical wire through the conduit and connect it to the terminals on the indoor and outdoor units.
• Ensure proper wire connections and secure the conduit to the wall.

7. Vacuum and Charge the Refrigerant System

• Connect a vacuum pump to the refrigerant lineset and evacuate the system for approximately 30 minutes.
• Close the vacuum pump and open the refrigerant valves on the indoor and outdoor units.
• Charge the system with the specified amount of refrigerant, as indicated in the manufacturer’s instructions.

8. Test the System

• Turn on the power to the system.
• Set the desired temperature on the indoor unit remote control.
• Monitor the system for proper operation and ensure there are no leaks or unusual noises.
