This is a tall narrow unit, works great except the unit does not drain anywhere. Strange, I don't see a punchout or anything to add a drain.
The bottom ends up filling about a 1/2" of condensate in the summer to where the fan ends up hitting the water. And it starts stinking...
Just getting it cleaned up for the summer, always wondered about this silly design...any thoughts?
Love this little unit (although I haven't cleaned it for a few years) it's for my workwhop where I build and repair guitars and it works awesome despite the wear and tear.

The drain hole is usually under the condensor coils. Drill a drain hole if you can't find it. It should be as far back as possible and at the lowest spot. 1/4" should be big enough.

Cool! do you have your own brand? Or web site? Do you have any used Martins for sale?

Yeah, I think a hole would be a good addition, nothing on the bottom of the unit. It's almost like it was designed this way, to self evaporate with help from the fan.
Got it cleaned up real nice now, thanks for the info!

Yes on the guitar brand. Let me scrounge up some info for ya. No used Martins right now. Just sent off an old Gibson archtop. Done lots of work on old Martin's, been at it for almost 30 years...
Had to make some new parts for this old one...

On most window a/c's the reclaimed moisture is flung against the hot condenser coil. As that water evaporates it aids in the cooling process but doesn't consume any additional energy (ie. free cooling!). Keeprite told us service agents it can increase the coling ability by 5-7% without using any additional power.

If you decide to drill a hole, avoid all the refrigerant tubing or you'll be sorry!
