Volkswagen Golf Service & Repair Manual: Draining air conditioner service station
 Note
| If it becomes necessary to drain the air conditioner service
station (e.g. because contaminated refrigerant was extracted),
all filters and dryers are to be renewed as a rule. Do not take
the filters and dryers out of their airtight packaging until
immediately prior to installation in order to keep moisture
absorption (hygroscopic property) as low as possible. |
| Refrigerant bottles that have been charged with
contaminated, used refrigerant are referred to as “recycling
bottles”. |
| Recycling bottles must be evacuated as a rule before being
filled for the first time with refrigerant. Refrigerant bottles
that have air in them must not be filled with refrigerant. |
| Different types of refrigerants must not be mixed with each
other. Mixed refrigerants cannot be processed for reuse. They
have to be disposed of. If the composition of the contents of
the bottle is uncertain, the refrigerant recycler must be
informed of this. |
WARNING
| When charging recycling bottles (compressed gas
containers), observe existing regulations, technical
rules and laws. |
| Never overcharge recycling bottles. The gas cushion
(expansion space) of overcharged recycling bottles is
too small to accommodate expansion of the fluid caused
by a rise in temperature. There is a risk that the
bottle will burst. |
| For your own safety, use only recycling bottles with
a built-in safety release valve. |
| Recycling bottles must be weighed on a calibrated
scale while being charged. The maximum permitted charge
quantity is 75% (fill factor 0.75) of the charge weight
shown on the recycling bottle (the possibility cannot be
excluded that along with the refrigerant, refrigerant
oil is drawn into the recycling bottle). |
