Do I have to braze the suction lines on a heat pump when installing a unit that takes 410a refrigerant?
Most likely, unless it’s a ductless mini-split system that uses flare connections. Check your equipment installation manual to be sure.
I bought a 41123 liquid to vapor converter. Which side should face the r410 cylinder, the male or female side? Or, which is liquid side and which is vapor side?
Thank you for your question. The orifice inside the 41123 liquid charging adapter will give the same performance with either direction of flow. It is intended to be installed directly onto the male cylinder port.
Q. Why Does the Micron Reading Rise?
A. With any electronic gauge it is normal for the reading to increase after the system is isolated from the vacuum pump. This indicates that molecules – mostly water vapor – are still detaching from the interior surfaces of the system. The rate of increase will give an indication of how “contaminated” the system is,…
Q. What is a Micron
A. A micron is 1/1000 of a millimeter, or about 40 millionths of an inch. When we refer to microns as a unit of measurement for vacuum, we are referring to microns of mercury in the same way we refer to atmospheric pressure in inches of mercury using a barometer.
