TEYU ECU-300 cabinet air conditioner requires proper installation for reliable cooling and airflow. Before installation, confirm the model, power supply, accessories, and mounting dimensions. Choose a stable cabinet side panel with unobstructed airflow and install the unit upright using all six fixing points.
After installation, connect the drain hose with a natural downward slope and check the mounting, insulation, airflow, drainage, and grounding before powering on. During the first start-up, verify normal supply and return airflow and check for water leakage. Regularly clean the dust filter to help maintain cooling performance. The temperature setting range is 25–38°C and should be adjusted according to actual operating conditions.
