KC called me about 1AM and in the background I could hear the VESDA alarm. He said that PF1 had tripped and he could not get it restarted. When I came in the Fire Dept was here and said that once KC had opened the disconnect to PF1 the VESDA levels dropped. We then restarted the fan and after a few minutes the VESDA levels began to rise. KC opened the disconnect and the lewvels dropped. The duty mechanic is looking into the problem now. It could be bad belts.

Coll. hall diff. pressure went into alarm. I silenced it. The wheather is very windy which I think is the cause. PF-1 being off may contribute to this alarm also. (0.160 "H20)

<pre>Talked to Ben at Fluitron, 215-355-9970, who recommends that ISO 10 hydraulic oil be used.  Motor oil is too thick.  In particular he recommends Velasite #6, which is an ISO 10 oil.  It is available from WW Grainger.  Ben gave me Grainger part 4ZF38.</pre>

<table border=0><td><tr><td bgcolor=#e0e030>We just ordered 6 gallons of the correct oil and Warren is headed out to Grainger to pick it up. In the mean time I have switched back to "Once Through" and Warren has started to drain the current oil out of the pump. We should have this back up and running this afternoon.</td></tr></td></table>

<p> The pump was flushed and filled with the lighter weight oil and we have returned to recirculation mode. It is at 165SCFH and was working right out of the box.
