How to identify and repair restrictions and damage in the liquid line
March 6, 2017
In last month’s article, “Inside Filter Driers,” which appeared on Page 18 of the Feb. 6 issue of The NEWS, we covered the internal construction, filtering, and drying materials within a refrigerant filter drier. This month, we’ll deal with troubleshooting, service, and replacement of the filter drier.
Filter driers are designed to remove foreign materials, such as moisture, dirt, sandpaper grit, soldering flux, small solder beads, and acid from a refrigeration or air conditioning system. However, filter driers are notorious for becoming restricted from moisture, sludge, dirt, or oil that has entered the system from a poor service practice or extreme operating conditions.
The SUD8358 Magna-Clean™ copper spun magnetic filter drier reduces and captures microscopic steel, iron, stainless steel, moisture, and other particles as the refrigerant flows through the air conditioning or refrigeration (ACR) system.
