01/01/2010 - The use of virgin R22 shall be prohibited in the maintenance and servicing of refrigeration and air conditioning equipment existing at that date, only recycled R22 can be used.
From 01/01/2015 - The use of recycled R22 will be prohibited in the maintenance and servicing of refrigeration and air conditioning equipment existing at that date.
It should be noted that the bans described above refer to the use of HCFCs.
In terms of considering what action needs to be taken it should be noted that use in relation to equipment containing HCFCs means -
"the utilisation of controlled substances in the production or maintenance, in particular refilling, of products or equipment"
This means that it is permissible to carry on using equipment that contains HCFCs beyond the phaseout dates, but there must be no maintenance or servicing undertaken on the equipment that involves breaking into the refrigerant circuits - See More or Please ring for details.
