[RE-wrenches] Cracked Glass...Warranty?

[David Lauzon]

If you used rail and the nuts were too tight there is potential for the
glass to break with no real sign due to the glass actually flexing too much.

In my business I see quite a few broken modules each year. As I recall, in
every instance there is a visible point where the impact occurred. Typically
a small radial pattern is around the impact point but then random patterns
over the rest on the module. Look close. Hope this helps.

Wrenches,

I recently inspected a system I installed in 2010, because the owner
commented that it appeared the frost wasn't melting off of one particular
module as it was from the others.  Turns out the module glass is shattered.
There are no obvious (that i can see) impact points, leading to the
question... Why did the glass shatter?

 

I don't want to just assume, but if there is no sign of impact, I'm
wondering if this could be a warranty issue?  Frame expansion/contraction
due to temperature swing maybe?

 

Any experiences, thoughts or advice?

 

Module is a Sanyo HIT N215A01

 

Thanks,
