Condensation inside the fixture is normal in
some atmospheric conditions. The fixture will
gradually expel humidity via its Gore-Tex
pressure relief valve as it cycles on and off.
If required, you can remove excessive
humidity by following the directions given in
'Removing and reinstalling the top cover'
starting on page 32.
