6.4 Leak testing
Once all the connections have been made, the
pressure gauge station is attached to the Schrader
valve as follows (if fitted):
red = small valve = high pressure
blue = large valve = suction pressure
Leak testing involves spraying a leak detection
spray onto the connections. If bubbles are visible,
the connections have not been made properly.
Then tighten the screw connection.
NOTICE!
The escape of refrigerant contributes to climatic
change. In the event of escape, refrigerant with
a low greenhouse potential has a lesser impact
on global warming than those with a high
greenhouse potential. This device contains
refrigerant with a greenhouse potential of 2088.
That means the escape of 1 kg of this refrig-
erant has an effect on global warming that is
2088 times greater than 1 kg CO

, based on
100 years. Do not conduct any work on the
refrigerant circuit or dismantle the device -
always enlist the help of qualified experts.
