Draining The A/C Service Station - Skoda Citigo 2012 Workshop Manual

Draining the A/C service station

Note
If it is necessary to drain the A/C service station (e.g. because
♦
contaminated refrigerant was drained off), always replace all
the filters and dessicators (shortly before installing, remove
the filters and dessicators from the airtight sealed transport
packaging in order to keep the increase of humidity as low as
possible).
Refrigerant bottles which are filled with contaminated and
♦
used refrigerant are known under the designation "recycling
bottles".
Always evacuate recycling bottles before filling with refrigerant
♦
for the first time (refrigerant bottles, in which there is air, must
not be filled with refrigerant).
Different types of refrigerants must not be mixed with each
♦
other (refrigerant mixtures can no longer be recycled yet they
must be disposed of). If there is any doubt about the compo‐
sition of the bottle content, the refrigerant operator must be
advised.
Caution
♦ When filling up recycling bottles (pressure gas tanks) the
existing regulations, technical rules and laws must be ob‐
served.
♦ In any case, avoid overfilling the recycling bottles (overfil‐
led recycling bottles have a too low gas blanket in order to
absorb the liquid expansion caused by the effect of the
heat). There is a risk of bursting.
♦ For your own safety, only use recycling bottles with a
safety valve fitted.
♦ Recycling bottles must be weighed on a calibrated scale
when filling up. The maximum authorised filling capacity
is 75 % (filling factor 0.75) of the filling weight given on the
recycling bottle (it cannot be excluded that besides the re‐
frigerant, refrigerant oil is also filled into the recycling
bottle).
