Running-In Instructions Of The Ac Compressor; Reasons For Rinsing The Refrigerant Circuit - Skoda Citigo 2012 Workshop Manual

Make sure the centring sleeves -arrows- is sit correctly, and make
sure the contact surfaces are clean.
– Fill the refrigerant circuit with the aid of the A/C service station.
– Before switching on the engine, observe the start-up instruc‐
tions of the AC compressor
6.5 Running-in instructions of the AC com‐
pressor
After the initial filling of the refrigerant circuit or after flushing/
blowing through the refrigerant circuit, the total volume of refrig‐
erant oil is contained in the AC compressor.
To avoid damaging the AC compressor, the AC compressor must
be loaded as follows:
– Position the rotary switch for air distribution on "person flow".
– Open all dash panel vents.
– Position the fresh-air blower switch at least on speed 3.
– Position rotary switch for temperature selection on the left stop
(minimum temperature).
– Start engine.
– Switch on air condition system once idle stabilisation has been
achieved (after approx. 5 seconds).
– Run engine without interruption for at least 2 minutes at idle
speed.
Maximum engine speed: 1500 min
– Subsequently switch off engine.
This shuts off the oil distribution in the refrigerant circuit and the
AC compressor can be fully loaded.
6.6 Reasons for rinsing the refrigerant cir‐
cuit
The refrigerant circuit must be flushed with refrigerant R134a, if:
♦ dirt or other contaminations are present in the refrigerant cir‐
cuit
♦ When evacuating a tight refrigerant circuit the vacuum gauge
is not constant (there is humidity in the refrigerant circuit and
builds up pressure)
♦ If the refrigerant circuit has been left open for longer than the
standard assembly time (e.g. following an accident)
