Installing a split AC unit can be a rewarding project, providing comfort and efficiency to your living space. This guide will walk you through the process, ensuring you understand what to expect and how to get started.

Preparation and Planning

Choosing the Right Location

Before installation, select a location for the indoor and outdoor units. The indoor unit should be placed away from direct sunlight and heat sources. The outdoor unit requires a stable, level surface with adequate ventilation.

• Ensure there is enough space for maintenance and airflow.
• Avoid placing the unit near flammable materials.

Gathering Necessary Tools and Materials

Having the right tools on hand will streamline the installation process. Common tools include a drill, level, and wrench set.

1. Check the manufacturer's manual for specific tools required.
2. Purchase or rent specialized tools if needed.

Installation Process

Mounting the Indoor Unit

The indoor unit should be mounted securely to prevent vibrations. Use the mounting plate as a template and drill holes in the wall.

Tip: Use a level to ensure the unit is horizontally aligned.

Setting Up the Outdoor Unit

The outdoor unit installation is crucial for the system's efficiency. Ensure it is on a flat surface and securely fastened.

• Consider using a concrete pad for stability.
• Make sure there is a minimum of 12 inches of clearance around the unit.
