We recommend that customers before installing ice maker to buy a water purifier, water filter after the source of water as ice machine. If you did not use the water filter, there will be cause the following effects:

1. Unsanitary ice, the ice is not edible. ( consumers can not see it through eye)
2. The inlet water solenoid valve often get stuck (affect ice making efficiency)
3. Grow algae on the evaporator (affecting the life of the ice machine)

4. The pump will be blocked over time (affecting the life of the ice machine)
