Add 15 to 25 degrees F to the outdoor temperature (say 90+15=105 and 90+ 25=115) and look at the TEMPERATURE information for R-22 on the gauge (green ring of numbers). THE HIGH SIDE NEEDLE SHOULD POINT TO A TEMPERATURE BETWEEN 105 AND 115 (in the green ring of numbers) AND THE PRESSURE IS READ ON THE BLACK RING OF NUMBERS FOR PRESSURE.
