When do you drop below the low pressure limit?

When do you drop below the low pressure limit?

If you are above the low pressure limit all the time, then you should be fine. If you drop below that when the compressor is running, the compressor will stop. The pressure when the compressor is not running is irrelevant. – HandyHowie Oct 8 ’15 at 9:21 That chart is not universal. You should be fine.

What should the low side of a TriPac be?

Low side is low. High side is normal. Discussion in ‘ Trucks [ Eighteen Wheelers ] ‘ started by cainekh, Aug 3, 2013 . I’m completely stumped with my tripac. I just replaced my compressor after it went bad. Vacuumed the system. did not replace air dryer as it was replaced just a few weeks ago. The unit is cooling moderately well.

What should low side and high side pressures be?

However, after my recharge the highest low reading I see (right before clutch engages) is 40psi, and the highest reading I ever see for the high side is 150 (right before the clutch disengages.) Should I be concerned about these low operating pressures, given my starting ambient temperature?

Why is the AC clutch still cycling at a high rate?

By the way, if the problem is not resolved electronically, the AC clutch is still cycling at a high rate, then we have to focus on the mechanical aspects. This can be due to low refrigerant, but it can also be due to a number of other causes, as well.

What should low side and high side pressure be?

Low side pressure should be 35 psi, high side around 150 psi. Engine off, both sides will equalize to around 70 psi. [quote=”Timothy S” post=166739]So do you have 150 psi without operating the compressor?

Is it OK to charge by low side or high side?

This is why some manufacturers recommend charging refrigerant by mass rather than by high-side, low-side and ambient temperature values. As long as you have charged the system with the correct amount of refrigerant (which you have according to the tolerance defined in your manual), you should be fine.
