Feature
Due to the inherent danger of using a ‘ disposable ’ can , it is not meant for refilling or recovery at all , and possible injury and refrigerant burns , if it should fail or explode , due to overfilling are likely .
It is crucial to be aware of how much refrigerant a service cylinder can recover too , with regards to the refrigerant in question , as densities and weight of refrigerants all differ , and overfilling is a risk . Caution must always be practised when working with any refrigerant , as the burns caused by them heal very slowly , and are extremely painful .
Always employ a drier when recovering , a separate drier for each different refrigerant you recover , it is also better to have a unit with an oil separator , as this will ensure you do not fill your service cylinders with nasty old oil when recovering ! Thus , if these simple guidelines are adhered to , your tool ’ s condition and your own safety , will never be a concern .
