    Need a little clarification.

    First of all, 40# is pretty good pressure, so I'm not sure what you mean with "leaving me no pressure at all".

    Secondly, 80# is really high. That is controlled by the switch. Every switch I have heard of is rated by the cutin/cutoff pressures, such as a 30/50 switch. Never heard of one with a cutoff of 80, so how are you getting pressure that high?

    At any rate, well pressure is controlled by the switch. You can adjust that by turning the large, center nut under the grey housing (with power off). Turn clockwise a full turn to turn pressure up, or ccw to turn pressure down. Then turn the power back on and see what you have by cycling the pump. Keep adjusting until you get what you want.

What is the correct suction pressure and head pressure for a 3 ton tempstar heat pump [ 1 Answers ]

When the yellow jacket brand gauges are put on a 3 ton Tempstar heat pump what should the correct suction pressure and head pressure be. I suspect it to be overcharged in freon. Because it is freezing the compressor, accumulator tank and all the lines soild ice.
