The suction pressure, also known as the low-side pressure, for a 404A cooler typically falls between 55-70 psi. This pressure ensures that the refrigerant evaporates at the desired temperature in the evaporator, providing efficient cooling. It's worth noting that the exact suction pressure can vary based on factors like the system's load ...It was about 100f ambient. 5ton 3 phase gas pack factory charged. I had fluctuating pressures and a temperature drop across liquid line drier. Removed it replace charged to factory charge. Now I have a suction pressure of 100 and discharge at 248 psi suction and evap sweating but no condensation draining from the condensate line. Good amps and good voltage.404a pressures are not mere numbers; they are the heartbeat of your ice maker. Operating within specific pressure ranges, typically measured in pounds per square inch (psi), these pressures ensure that your ice machine runs like a well-oiled chariot. Too high or too low, and you're veering into the realm of inefficiency and potential breakdowns.operation including a high-pressure switch lockout condition. † Only use indoor coils approved for use on R-410A systems.
