5.4. End of useful life
When scraping the unit or the cooling skid, contact your
local authority to enquire what the possibilities are for
recycling or processing. The ComfoCool contains coolant
R134a. It is essential that the coolant is disposed of in an
environmentally friendly manner. If not disposed of prop-
erly, the contribution to greenhouse gas emissions of the
volume of coolant in this system equals 700kg CO
2
.
