Components Of The Refrigerant Circuit Leaking Or Damaged - Refrigerant Is Still In The Refrigerant Circuit; Replace Ac Compressor - Skoda Citigo 2012 Workshop Manual

⇒ "10.5 Replace catch pan and throttle/fluid reservoir",
page 94 .
– Assemble the refrigerant circuit, evacuate and fill again.
– Check the function of the air conditioning system.
10.3 Components of the refrigerant circuit
leaking or damaged - refrigerant is still
in the refrigerant circuit
– Empty the refrigerant circuit with the aid of the A/C service
station.
– Remove defective component, blow through with compressed
air and while doing so collect any refrigerant oil which flows
out (disposal of used oil
⇒ "3 Legal texts and legal regulations", page 33
– The volume of refrigerant oil blown out must be filled into the
new component as fresh refrigerant oil volume, plus:
♦ for the evaporator - 20 cm
♦ for the condenser, coolant pipes and refrigerant hoses - 10
3
cm .
– Vehicle with throttle - replace throttle.
– Assemble the refrigerant circuit, evacuate and fill again.
– Check the function of the air conditioning system.

10.4.1 When there is no need to eliminate im‐
purities in the refrigerant circuit e.g. for
external damage after an accident
– Empty the refrigerant circuit with the aid of the A/C service
station.
– Remove the air conditioning compressor.
– Unscrew the oil drain plug from the removed AC compressor
(replace O-ring ⇒ Electronic Catalogue of Original Parts ) and
drain oil. In order to speed up the evacuation of the refrigerant
oil, turn the AC compressor with the clutch disk of the magnetic
coupling. Collect oil in a measuring vessel (disposal of used
oil ⇒ "3 Legal texts and legal regulations", page 33
– Drain oil out of the new A/C compressor using the same meth‐
od (attention - do not mix with the oil out of the removed A/C
compressor) and fill in again an amount of refrigerant oil which
corresponds to the oil quantity drained (the refrigerant oil
drained from the original part A/C compressor maybe used).
Example:
3
If 70 cm of refrigerant oil was drained out of the defective AC
compressor and 140 cm
original part AC compressor (a small amount of refrigerant oil re‐
mains in the AC compressor). In this case, fill in 70 cm
refrigerant oil into the installed AC compressor.
