Cleaning the exterior surfaces

So as not to alter the opacity of the painted plastic
panel (ref. A fig. fig. 33) use mild degreasers that do
not contain Mek or aggressive alcohols.
To clean the glass panel (ref. B fig. fig. 33), use iso-
propyl alcohol.
To clean the side panels (ref. C fig. fig. 33), use a mild
