Hey Turbo,
I'd like to see what info you have too if you don't mind. Emails in my profile.
Thanks.

Is it a large file? im not sure why it wouldn't go through, no worries.

Does a CVHF like 65 deg tower water????? Maybe It's just growling at you a little bit!

Could the problem be CVH(F). Generally speaking some of the earlier versions of this machine that we have were plaqued with leak problems. The newer version seem to have ironed out the problem. The problems as I saw it were excessive vibrations at low loads and flanges that were bolted way to light weight for their size. Then with excessive leaks came lots of run time on the purge units causing purge break downs to increase. Of coarse there a many reasons for surge, I'm just taking my shot at the F model cause I needed to vent. Not my favorite machine. Not as dependable as they needed to be.

What would be an example of your favorite machine?

Just want to know for comparison sake.

It's less than a Meg, I'll try it again and see.

Ditaw, sent it again, looks like it went through this time. BTW the pic in your profile brings back recent memories.

Really the only issue I ever had with an F was condensation getting into the oil pump motor terminal box and blowing up the relay and also the leads melting off the oil heater both easy fixes and pretty minor imo

WITH TOWER WATER THAT COLD ITS POSSIBLY A LOW SIDE SURGE . RAISE UP THE TOWER WATER TEMP.

I've never had too much of an issue w/ them either, I have experienced the exact same problems that you speak of.
