Subject: Re: 2.5m obslog 20031215 (MJD 52989) - Chiller pressure
	Relative to operating pressure maybe so.  The system
has a bypass pressure release valve located just after the output of
each pump designed to pressure release at (if I remember correctly)
90 psi.  The system can operate beyond this limit.
	So 50 is higher than normal, but not a problem unless the
valve pops off, which the flow switch would send a flag.
