Setup and Installation

Proper setup is crucial for optimal performance and longevity of your ice maker.

Unpacking

• Carefully remove all packaging materials.
• Inspect the ice maker for any shipping damage. Report any damage to your supplier immediately.
• Ensure all accessories are present: ice scoop, water hose, drain hose.

Placement

• Place the ice maker on a firm, level surface capable of supporting its weight when full of ice and water.
• Allow adequate clearance around the unit for proper ventilation (at least 5 inches from walls).
• Avoid direct sunlight or heat sources.
• Ensure the ambient temperature is within the recommended operating range (typically 50°F to 90°F / 10°C to 32°C).

Water and Drainage Connection

The ice maker requires a continuous water supply and a gravity drainage system.

1. Connect the provided water hose to the water inlet on the back of the machine and to a potable water supply. Ensure connections are secure to prevent leaks.
2. Connect the drain hose to the drain outlet on the back of the machine and route it to a floor drain or suitable drainage point. Ensure the drain hose has a continuous downward slope for gravity drainage.

Initial Preparation

• After placement and connection, allow the unit to stand upright for at least 24 hours before plugging it in. This allows the refrigerant to settle.
• Before making the first batch of ice, perform a cleaning cycle as described in the "Maintenance" section.

Ice Full Reminder

When the ice storage bin reaches its maximum capacity (approximately 29 lbs), the "Ice Full" indicator on the control panel will illuminate, and the machine will pause ice production. Empty the ice bin promptly to resume operation and prevent overflow.

Timer Function

The 24-hour timer allows you to schedule ice production. Use the + or - buttons to set the desired delay for the machine to start or stop.
