LUBRICATION Westron 404a requires a POLYESTER (POE) Lubricant to ensure complete miscibility between oil and refrigerant. Miscibility is important for oil return to the compressor especially in a large system with long runs of piping.
POE Oil absorbs moisture quickly when it is exposed to the atmosphere. Any way please handle the equipment very carefully and avoid prolonged exposure to air.
