Wondering if anyone can help been working on a carrier chiller 30 gx and has tripped on code 68 which is to high a oil pressure.
5 days agao it tripped on low oil pressure code 70 so read the manual and added 4 litres of sw220 oil and the chiller ran ok.
Due to the fact there is no oil level sight glass and only a oil level transducer I have no idea if the oil sep is near the recommended level of 40 litres.
I am at the stage of recommending decanting the circuit removing what oil there is and changing the pre oil lube filter and also the oil filter at the back of the screw compressor. Could it be partially or wholly blocked causing the high oil pressure ?
Any advice would be welcome.Thank You
