The figures that belong to this topic
- Appliances must be properly evacuated before disposal: larger appliances to the Table 1 levels set by pressure class, charge size and equipment age, with low-pressure appliances taken to 25 mm Hg absolute.
- Purged refrigerant destroyed at 98 percent or greater verified efficiency may be excluded from leak-rate calculations.
Go deeper: the small appliance definition and the evacuation levels required before disposal.
