A:Answer According to the manual, no.
You only drain the unit when using it in Dry Mode, which is an AC mode with no moisture in the cool air--for this they say you need to hook up a hose to the unit for continual drainage--or when you unplug the unit and first put it into storage for the Winter in planned non-use--for this, you just pull out a little stop at the bottom of the unit and let the condensate drip out into a little tray until its done.
Normal AC operation, which they label as "Cool" mode, will use the condensation normally generated in the process to put a little moisture in the air, which is preferable if you live in a normally dry climate.
