Running pressures for 410a.

Low-pressure switches on Carrier equipment using R-410A are usually set to open at about 50 psi and close at about 100 psi. Note: Heat pumps operating in the heating mode also may have a vapor switch that cycles the outdoor fan when the pressure is about 400 psi, and resets when the pressure drops to about 310 psi.(R-508B) is a better replacement than Freon™ 410A. Properties Freon™ 410A is safe to use when proper storage and handling practices are followed. It is a nonflammable, low toxicity mixture of HFC-32 and HFC-125 (50/50 wt%).
