<DIV><FONT face=Arial size=2>Hi Alan,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The white pads were discontinued when our vendor could not guarantee their composition. We received one lot where the composition varied enough to cause sticking to the humidifier heater bars in areas where winter dryness was extreme.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>We tested bars where the residue was left on and new white pads were applied. These still evaporated water at a rate as good or better than new white pads on a clean bar. Thus, we felt it was a cosmetic issue and not a performance problem.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>However, we received enough complaints that we discontinued the white pads and brought back the blue.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I do have a technician in the eastern US who swears by the white pads. He is running a side by side test this winter on the systems he maintains with white pads that we saved when we discontinued them. It will be good to have more data, but I'm not sure this will affect anything.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I hope this helps.</FONT></DIV>

<P>I just found a box of those white DC pads. Wasn't there some bad news about those? What's the story? Inquiring tuners want to know.</P>
