Re: [A/S] Armstrong A/C Model 21-12

Removing the old Armstrong is not that easy I been told. If you replace it
you should have an Airstream repair shop do it. There are just to many
differences between an Airstream and a SOB that I would not want someone
work on mine that is not familiar with Airstreams. As for a replacement
unit, only the Dometic Penguin can be equipped with the drip pan and
therefore drain the condensation off through the existing drain tube that
the Armstrong uses. All others with drain the condensation on the top and it
will run down the outside.

I would not give up on the Armstrong until I was sure that I could not find
the part you need. Good luck
