    Not to derail the thread, but has anyone seen oil level fluctuations in older high sump CVHE/F chillers that have been retrofitted with a drive? With the vanes wide open, the sump pressure seems to be a shade over evap a making the eductor even more critical. I've had the level drop to the bottom of the lower sight glass at lower loads and obviously come back up as it runs harder. This is on a freshly rebuilt machine. Oil seal tolerances are in spec and tower water is a pretty consistent 70 with a 42 chilled water setpoint.
    Yes, i have two machines that i have retrofitted that act exactly as you have described. One of which had a rebuild, adaptiview and Afd installed at the same time. These machines do not have an angle valve on eductor line so there is no throttling it back, there is a good bit of foaming untill the machine loads up and oil starts coming back. I have not dug into this yet but it is something that i have noticed.
