High humidity in winter?

[Elian Degen J.]

Mike,
Dale is right

You should check the piano thoroughly before installinh a DC
The main problems I encountered have been with old pianos mostly
Where I work there are many places were humidity is high all year through.
When the instrument has been subjected to hi level humidity for many years,
the wood and felts swell, sometimes you see one of this pianos which seem to
be working well, but the moment you take the humidity level to what would be
the normal level, screws become loose, centerpins become loose, and even
tuning pins go loose.

Now all DC units ( I have seen ) installed since the piano was new or before
the piano is placed in a high humidity place worked fine and the instruments
are kept well
