What is the high and low on the compessor of a 30 year old Manitowoc ice machine model number ED0402A?
first off, this machine was built as a R-502 unit. If the refrigeration side has been worked on it will probably have been changed to some other refrigerant at a major cost. We also don't know your ambient air temp where the unit is, or incoming water temp. There-fore we can't possibly give you a answer to your question. However you can determine the head pressure and suction pressure with a good thermometer and pressure charts for the refrigerant that is in the unit. Be advised that the suction temp varies depending on where in the cycle the machine is..
What is the reason you are into the refrigeration side? Machines original problem?
