Looking for a Bay Voltex Tempryte operating manual for HT-3510 serie

This is a touch off subject but I am putting together infrastructure for
some experiments.
I have several 20 year old Bay Voltex Tempryte chillers of the HT-3510
series. I have repaired the problems listed on the tags of the first two
then pushed the start button and nothing happens. The problems
consisting of frozen bearings in the water pumps and circuit breakers
missing. I jumpered across the magnetic input breaker, the water pumps
ran, the compressor did its thing, water got cold. So the basic
functionality works. I have bypassed the one obvious interlock into the
high voltage section. I am missing something basic in my understanding
of how these chillers operate. These are units that I obtained as part
of a university auction of a large lab lot. The goal is to put together
an operating one and use it for cooling turbo pumps and magnetic coils.
