Answer :
Final answer:
The manifold low side gauge for R410a refrigerant must range to 300 psi(d) due to high pressures of R410a.
Explanation:
The manifold low side gauge for R410a refrigerant must have a range that is appropriate for the pressures encountered when working with this refrigerant. R410a, like other refrigerants, works under high pressure.
Hence, the manifold low side gauge for R410a must range to 300 psi (option d). If we refer to the open-tube manometer - a device used to measure pressure, the fluid depth must be the same on both sides indicating a balance.
This balance in pressure is what the gauge is used for, reading the pressure of the refrigerant in the system. At 300 psi, the gauge is designed to handle the high pressures of R410a.
