🛠️ Step-by-Step Visual Checklist:

Choose Ideal Location — cool, interior space
Cut Opening in Wall — frame with proper dimensions
Install Drain Line — connect to a safe discharge point
Mount the Unit — use brackets or supports
Seal & Insulate — weather stripping or foam
Connect Power — to dedicated 110V/220V outlet

Ventilation and Airflow Tips

Proper airflow is essential for cooling units to function correctly.

Passive Ventilation: OK for smaller systems
Active Ventilation: Ductwork or exhaust fans required for larger installs

Leave 3–5 inches of clearance around unit vents. Never obstruct airflow with shelves or stored bottles.
