I am replacing the filter dryers on a carrier gemini 38ard024 I'm confused cause there is 2 compressors. so I vacuumed down both sets of lines to 500 microns. Then I filled the high side with r-22 on both compressors. thinking I can finish charging it when I turn it on. I turn it on and it runs for bout a minute and cuts off. my gauges both spike. and the circut breaker pops. It wont run long enough for me to get my pressures accurate. Is it locked out now??? What should I do???

What should the high pressure line read to be fully charged on my RUUD UAKA-042 a/c unit? The specs on the unit has a design pressure of 300 PSI on the high pressure line and 150 PSI on the low pressure line. Is that the operating pressure for the high pressure charge or the maximum value that the system can with stand before rupturing a line or component?


That is a desing pressure not an operation pressure. opperating pressuers will vary with load so pressure alone will not tell you if you have the proper charge. the proper method is with superheat or subcooling, depending on the type of metering devi ... Ruud UAKA042 Air Conditioner

With the Marley thermostats the temperature is controlled by "comfort zones" instead of individual degrees on temperature control dial. I am not sure how to control the temperature.

Anyway, the temperate set up on the control has like a long line of temperature settings for both cycles (hot and cold) and you have to move the little marker thing up or down, as you do, the system beeps to recognise there ha
