Preparation

Before you begin, ensure you have the following tools on hand: screwdriver, drill, drill bits, 7/8" hole saw, open-end wrench, tubing cutter, vacuum pump, and gauges. Familiarize yourself with the included installation instructions and consul the manufacturer's guide for specific details.

The Installation Process

1. **Mount the outdoor unit**: Position and secure the outdoor unit on a flat, sturdy surface near an exterior wall. Leave sufficient clearance for air circulation.

2. **Mount the indoor unit**: Decide on the optimal location for your indoor unit, typically on a wall, and secure it in place. Ensure it's level and several inches from the ceiling or floor for effective air circulation.
