DW Copeland
Got a 8 hp semi . Had a call out over the weekend. Unit had tripped on oil pressure switch. I reset it despite a warning on the control that do not reset in case of compressor damage.
A previous engineer had changed the oil. System runs on R22. Trips out at regular intervals.
Why is it doing this and what are the tests that can be carried out to ascertain if the oil pump is not doing its job
Thank you
