Procedure for the internal leak inspection
The internal unit pressure test is performed automatically once a day.
Firstly, the service hose connections to an air conditioning system are
checked and to see whether the service connectors are installed.
If pressure is still in the hoses, it causes an error. If the service hoses
are full, a refrigerant analysis is performed and the refrigerant is then
recycled if the
“Analysis OK”
message appears. Afterwards, the
vacuum test is performed. Several parts of the unit are evacuated.
Once the vacuum test has been carried out successfully, the parts of
the unit are filled with refrigerant – now a 6 minute pressure test is
done with all the solenoid valves open to immediately determine a
drop in pressure. After successful completion, the refrigerant is
suctioned off and the unit is available for service work.

The switch-on delay runs for 35 seconds and the housing is venti-
lated. The software version number then appears in the display (

for several seconds:
“SW”
: Software status
“DB”
: Database
