I have the service manual provided by Scotsman. It does not give low side pressures other than maximum operating pressures which is 30PSI low side and 265 hi side (Uses R134A). This is not the correct running pressure is it? I bet jumpy knows this one. These photos was taken last night. It is been running all night not nary an ice cube in there. Got good spray, good water supply, am thinking this puppy needs a charge. The water is cold so I know it has some gas in there. These dang ice machines are tricky. How much should I add or should I just go by amp draw? Click on pictures to enlarge.
