The turbo runs with a lower current now (was 6.5 A now 3.5 A) during standby. It should be less than 2 A. We will continue looking for the leak but as of now, the system is ok to run.

From shott at snf.stanford.edu Tue Sep 22 08:24:44 2009 From: shott at snf.stanford.edu (shott at snf.stanford.edu) Date: Tue, 22 Sep 2009 08:24:44 -0700 Subject: Problem lampoly SNF 2009-09-22 00:50:49: water chiller failed Message-ID: We have had slow leakage out of the particle filter housing for some time that ultimately results in a low level signal. I tried to re-wrap the fittings with teflon tape but, in the process, split the white 1/2 NPT to 3/4 NPT adapter. I've cleaned up my mess and temporarily elminated the particle filter housing using a 1/2"-1/2" Swagelok union. I'm in the process of trying to order a Pentek ST-1 (or equivalent) particle filter. The ST-1 is a stainless steel cartridge filter that will be better for this high-temperature application and will allow us to have all-steel fittings to reduce the chace of rupture. At the moment, however, the 50/50 glycol/lwater has been topped off and the system is ready to go. Thanks, John
