Hi All
I am after a service manual for a Copeland D4D4A-200-AWM/D please.
We are having trouble with a compressor loosing its oil pressure and occasionally tripping the OFS. The filter has been cleaned and replaced. The oil temperature is about 35oC.
It has been noticed that the oil pressure drops gradually.
Any assistance would be appreciated.
Regards
Paul

Is the compressor controlled by VSD?

Thanks for the links, had the Emerson document on the OFS but not the other, I will pass on to our Tech who is having the problem.

As far as I know it is star/delta start, no VSD.
