hello jay
surely the compressor units are integrally mounted in the base.
And the temperature rise in the case is due to the ambient temperarure in the shop rising having a proportional effect on how the unit condenses.I cant see the compressor/condenser being remotely mounted using capillary tube .
I have seen it done and im not saying it wont work,however as well as being very bad practice i think the compressor would soon reach the end of its working life.Lol
Capillary systems dont cope very well with high ambients(in the uk anyway)maybe its just the design of our equiptment in the uk.
