Question 2

Can zeotropes be metered in with the unit operating?

A) No, if an early R-410A cylinder with a dip tube is being used.
B) Yes, only if the temperature exposure of the cylinder is above 125F.
C) Yes, by slightly cracking open the low-side manifold valve and then closing it.
D) No, as the system must be turned off first.
