The coolant bottle must be vertical to fill the system with the valve on top. The
check boards are used for filling.
WARNING
If coolant is added as a liquid on the vacuum side (bottle
upside down), then the compressor will be destroyed by the
liquid.
c) Prepare and fill according to the operating instructions for the R134 maintenance
device. Filling is complete when no more bubbles can be seen forming in the
glass front.

– Switch off the air conditioner and vehicle engine
– Removing the test manometer
– Screw on the gasket caps.
