Cassette Air Conditioner What To Do About My Leaking 'ceiling Type' Cassette Split Air Conditioner?

What to do about my leaking 'ceiling type' cassette split air conditioner? - cassette air conditioner

I recently has the cost of installing a new split air conditioning - the type of cassette single, "begins in the middle of my upper limit for the main room.

To my great regret, last summer, no water trickling from the mainframe tape on my floor.

The air conditioning is a model of the "brand" and I can not believe I will have this problem.

How can I prevent the escape of this water (condensation?) From the roof outlet.

I would be pleased to find some good advice.

Thank you.
