Quick Setup & Use
- Unpack the unit and remove all exterior/interior packaging materials; check package contents.
- Recommended: leave the ice maker for 24 hours after unpacking.
- Clean the interior with lukewarm water and a soft cloth, or run the Self-Clean function.
- Place the ice maker on an even, flat surface in a well-ventilated indoor location, away from direct sunlight and heat sources, with at least 15 inches clearance to the walls.
- Connect water using a potable/drinking-water source meeting local standards; ensure water pressure is 0.1–0.4 Mpa (use a pressure reducing valve if above 0.4 Mpa).
- Connect the drainage pipe before using: connect one end to the machine and route the other end to a container/sewer; keep the other drain port lower than the machine’s drain port.
- Allow 1 hour for the refrigerant to settle before initial use; position the unit so the plug is accessible.
- To start: in standby mode, press the ON/OFF button briefly.
- To clean before use or after long downtime: run Self-Clean using water + vinegar or lemon juice (1:1), then hold ON/OFF for ~3 seconds to start; when finished, unplug and drain, then dry; repeat once to rinse out residue.
- To take ice cubes: wash hands, use the provided plastic ice scoop, close the door after taking ice, and avoid putting anything else in the machine.

Troubleshooting
- E1 (Temperature sensor short/circuit/open circuit): If the display shows E1 when powered on, replace the sensor circuit or sensor.
- E2 (Display anomaly / motor not running or evaporator sensor damaged): Replace the faulty components.
- E3 (Condenser/fan issue): If the condenser probe isn’t sensitive, check/resolve the probe sensitivity; if the fan is not working or jammed, unplug and then either adjust the fan or replace the faulty fan; if needed, replace the fan.
- E4/6 (Ice full): This indicates the ice bin is full; address related conditions and ensure normal operation (if the fan is broken, replace it; if the infrared through-beam tube is blocked, remove obstructions or wipe the infrared receiving/emitting port with a tissue).
- General note: If you suspect an electrical issue in a high-humidity environment, cut off power of the machine.
