Hi Everyone
I have a 30 year old Dunham Bush chiller which I am nursing along, but due to the age of the unit there is no wiring diagrams available.

If someone has any information for : Dunham Bush OPCA 200 Air Cooled Chiller that would be great.

The Chiller is made up of 2 separate sections bolted together so maybe a wiring diagram for a OPCA 100 may also be useful.

thanks Bobjob
