pressure side, etc.). It is also recommended to have spare seals for other components available during restart of the system. The same type of seal can be used; it should just be a new one that has not previously been in R-22 service. A rigorous leak check regime pre- and post-retrofit will minimize any refrigerant losses. Obviously, any seals ...MO99 Retrofit guide. The low side pressure with MO99 will be a couple of psi lower than R-22 while the high side (cond) will be slightly higher than R-22. The MO99 retrofit guide has a lot of useful information, including proper setting of superheat and subcool. It seems 15°of SH and 5-7° SC would be adequate.Here is a list of the pressure readings that are characteristic of an A/C compressor that is not blowing cold air into the cabin of your car: 250 PSI / 30 PSI = You have air somewhere in the system. 250 PSI / 50 PSI = The system is overcharged and the condenser is not cooling.

1. Optimal Cooling. When the low side pressure operates within the recommended range for 410a, your system can efficiently absorb heat from your indoor environment. Any deviation from this range might compromise the cooling efficiency, leaving certain areas less cooled than others. 2.

In the example of an R-410A packaged unit with a surrounding air temperature of 70°F, the pressure on both the high and low-pressure side of the system will be 201 PSIG. If a new R-410A refrigerant bottle had a surrounding air temperature of 70°F, the pressure inside the bottle would be 201 PSIG.

You need at least a 50 degree IWB and 55 degree ODB at minimum to measure superheat accurately. You can block the coil to simulate your ODB target if it's too low, but be careful how much you raise the head pressure or your SH will drop to 0 degrees. Use a superheat charging chart to determine whether or not you can check the charge.As AC low side pressure surges beyond the recommended range, the cooling process and overall system efficiency are imperiled. Subpar cooling capacity culminates in discomfort, compromised humidity control, and protracted cooling cycles. Moreover, the compressor may face strain due to an excessive workload, potentially accelerating wear and tear.Our Book https://www.acservicetech.com/the-book In this HVAC video I go over the reasons why the low side, vapor, suction pressure may be lower than normal w...I borrowed some gauges and got readings on the high side of 125 psi and the low pressure went up as high as 95 after 15-20 minutes.
