Re: SLA-500, heat exchangers

wouldn't a thermometer in the reservoir validate the functionality of
the heat exchanger? also the laser should shut down on an over temp
prior to any damage? and what serious damage will it cause? is the
detailed literature too long to post on the m/l?

>It has come to our attention that there are several problems

>
>1) The Coherent "Laser Pure 20" heat exchangers out in the field,
> are not the correct model, and may cause severe damage to your
> laser. They were not intended to be used with this model laser,
> and we can supply detailed literature upon your request.
>
>2) We have also seen "Laser Pure 40" models with the wrong

> To check for the correct component, remove the top lid,
> and remove the side panel from the LP-40 unit.
> (the side that has all the water fittings)
> Locate the stainless steel heat transfer unit.
> The unit should have the model # CB26-90H,
> if it does not, please contact us.

>We have only seen these problems, on systems with dates prior to
