Service Station, Draining

NOTE:

If it is necessary to drain the service station (for example, due to extraction of contaminated refrigerant), all filters and dryers must always be replaced (do not remove filter and dryer from the air-tight packaging until immediately before installation to minimize moisture absorption).

Refrigerant containers filled with contaminated used refrigerant are referred to as "Recycling containers".

Thoroughly evacuate the 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 may not be mixed together (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.

CAUTION:

When filling recycling containers (compressed-gas containers), 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 fitted 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).
