6. Then tighten the fittings with 2 appropriately-
sized open-ended spanners. Use one
spanner to counter the force when tightening
the fitting (Fig. 38).

7. Open the stop cocks with an Allen key before
switch the system on!

CAUTION!
Only open the stop cocks following complete
installation of the quick-release couplings and
before switching the system on!
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 cli-
matic change. In the event of escape, refrig-
erant 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 poten-
tial of 1975. That means the escape of 1 kg of
this refrigerant has an effect on global warming
that is 1975 times greater than 1 kg CO
2 ,
based on 100 years. Do not conduct any work
on the refrigerant circuit or dismantle the
device - always enlist the help of qualified
experts.
