Air Conditioning System Test Without Refrigerant Service - Waeco AirConServiceCenter VAS 6746B Operating Manual

VAS 6746B
8.7 Air conditioning system test without refrigerant
service
I
NOTE
The air conditioning can only be tested on vehicles with a low pressure
port and a high pressure port, or with a low pressure port only.
If you only test the function of a vehicle air conditioning system without
drawing off and recycling the refrigerant, the vehicle air conditioning sys-
tem would lack the refrigerant remaining in the service hoses of the air
conditioning unit after the test. The "A/C system test" menu item has
been added to compensate for this loss.
I
NOTE
The existing standard function processes "Short selection" and
"Free selection" already have a compensation function for service
hoses, which means the final air conditioning function test can be car-
ried out in the usual manner (the service hoses are drained by the
device).

air conditioning system and open them.
