Answer :
Final answer:
The manifold high side gauge for R410a refrigerant must range to 500 psi (option c).
Explanation:
The manifold high side gauge for R410a refrigerant must range to 500 psi (option c).
Refrigerant R410a operates at higher pressures compared to other refrigerants, such as R22. The high side gauge on a manifold set is used to measure the pressure on the high pressure side of the refrigeration system. The pressure on the high side of an R410a system can reach up to 500 psi, so the manifold high side gauge must have a range that can accommodate this pressure.
