- Refrigerant containers filled with contaminated used
refrigerant are referred to as "Recycling containers" .
- Always evacuate recycling containers prior to initial filling
with refrigerant (if there is air in a refrigerant container it is
not to be filled with refrigerant).
- Different types of refrigerant are not to be mixed
(refrigerant mixtures cannot be recycled and are to be
disposed of). If there is any doubt about the composition of
the contents of the container, the refrigerant recycling
company is to be informed accordingly.
Warning!
- When filling recycling containers (compressed-gas
vessels), observe applicable regulations, technical
rules and laws.
- Recycling containers are never to be overfilled
(overfilled containers do not have a sufficient gas
cushion to accommodate the liquid expansion caused
by the effects of heat. There is a danger of rupture).
- To ensure safety, make exclusive use of recycling
containers equipped with a safety valve.
- Recycling containers must be weighed on calibrated
scales during the filling process. The maximum
permissible capacity is 75% (charge factor 0.75) of the
charge weight indicated on the recycling container (the
possibility of refrigerant oil entering the recycling
container along with the refrigerant cannot be ruled
out).
Refrigerant circuit, cleaning (flushing) with
compressed air and nitrogen.
- Compressed air and nitrogen are to be used in order to
force out moisture and other contaminants as well as old
refrigerant oil as efficiently as possible, without wasting
refrigerant, without the need for extensive assembly work
and without endangering the environment.
Warning!
- Nitrogen can flow uncontrolled out of the cylinder.
- Make exclusive use of pressure reducers for nitrogen
cylinders.
- Use appropriate extraction units to draw off gas
mixture escaping from components.
