Setup and Installation
1. Location Requirements
- Place the ice maker on a flat, level surface capable of supporting its weight when full of ice and water.
- Ensure adequate air circulation around the unit. As an air-cooled model, it requires proper ventilation. Do not block the front air intake vents.
- Maintain a minimum clearance of 6 inches (15 cm) from walls or other obstructions for optimal airflow.
- Avoid direct sunlight or proximity to heat sources.
- The unit can be installed freestanding or built-in, provided ventilation requirements are met.
2. Leveling the Unit
The ice maker is equipped with adjustable leveling feet. Use a level to ensure the unit is perfectly level from front to back and side to side. Proper leveling is crucial for efficient ice production and drainage.
