A:AnswerThank you for your question!
Please make sure the unit is at least a 5 degree angle facing out of the house. If it is, then remove the plug from the bottom rear of the unit to get rid of excess water.
Thank you,

A:AnswerVery easy. Lightweight, I install and uninstall this unit all by myself. And carry it to my attic for winter storage. And I am a female. It's only like 60 pounds.
