In this episode you will learn: - Recovery cylinders must never be filled beyond 80% of their capacity by weight to allow for thermal expansion. - Always use a scale and know the cylinder's tare weight (TW) and water capacity (WC) to calculate the maximum fill level. - Overfilling can cause hydrostatic pressure, leading to a violent and dangerous cylinder rupture. - It is a violation to mix different types of refrigerants in the same recovery cylinder. - Recovery cylinders are gray with yellow tops and require hydrostatic testing every five years.
