Operating the Indigo NXT Ice Machine
This section guides you through powering on, understanding the ice production cycle, and adjusting ice thickness settings for optimal performance․
Powering On and Initial Startup
Before initial startup, ensure the Indigo NXT ice machine is correctly installed with proper water and electrical connections․ Verify all safety precautions are followed․ To power on, locate the main power switch, typically found on the front or side panel, and toggle it to the ‘ON’ position․
The touchscreen display will illuminate, initiating a self-diagnostic check․ Allow the machine to complete this process, which may take several minutes․ During this phase, the machine calibrates sensors and prepares for ice production․ Observe the display for any error messages; consult the troubleshooting section if issues arise․ Once the diagnostic is complete, the machine will enter standby mode, ready for operation․
Ice Production Cycle Explained
The Indigo NXT ice machine operates in a cyclical process: freeze, harvest, and fill․ During the freeze cycle, water is distributed over the evaporator plates, forming ice․ Once the desired ice thickness is achieved, the harvest cycle begins, releasing the ice from the plates․
This is typically accomplished through a warm gas or water spray․ The released ice falls into the storage bin․ Subsequently, the fill cycle replenishes the water reservoir, preparing for the next freeze cycle․ This automated process continues, maintaining a consistent ice supply․ Cycle times vary based on ambient temperature and ice thickness settings․
Adjusting Ice Thickness Settings
The Indigo NXT allows customization of ice thickness via the touchscreen interface․ Access the settings menu and navigate to the ice thickness adjustment option․ Users can select from pre-defined thickness levels, or manually input a desired value․
Thicker ice cubes melt slower, ideal for applications requiring prolonged cooling․ Thinner cubes are suited for faster chilling․ Note: Adjustments impact the ice production cycle length․ Monitor performance after changes․ Error code E19 indicates an ice thickness sensor issue, requiring professional attention․

Maintenance and Cleaning Procedures
Regular cleaning and scale removal are crucial for optimal performance․ This section details daily routines, descaling processes, and filter replacement schedules for your Indigo NXT․
