Horrible installation instructions and you have to really figure out how to use the drain lines. The drain pump is a joke and causes a mess. I removed it completely and just drain both houses to the outside of the building. This ice maker is really good though compared to others that I've had. We have had it like 4-5 moths and no issues with anything. Be patient with the installation and you might want to get your own drain lines from a hardware store to help make things last longer.
