6 . Operat ion
m
Before connecting service hoses proceed as follows:
1. Perform refrigerant identification (if equipped - see
chapter 6.3).
6.1 Ser vic e phases
y
Recover y phase: Refrigerant is extracted from the
vehicle, cleaned and routed into the internal refrigerant
bottle.
y
Vacuum phase: A vacuum is generated in the vehicle
air conditioning system and the system is checked for
leaks.
y
Rechar ge phase:
—
Refrigerant: The vehicle air conditioning system is
filled with a specified amount of R134a refrigerant.
6.2 A/ C Dat abase
t
If purchased, the A/C Database can be used to select
vehicle and determine the charge amount.
1. To enable, go to "Set up >> Selec t able Opt ions".
2. Press YES until screen displays "AC CAP DB In-
st alled?".
3. Use and to scroll to Ext er nal and press YES.
4. Once enabled, the unit will ask technician if they would
like to use AC Capacity Guide to determine charge
amount.
5. If YES is selected, the unit will proceed to allow user to
select Year, Make, Model, Engine, and any other options
the vehicle may have.
t
Database is updated yearly with current model year
vehicles. Updates can be purchased and downloaded
through the MAHLE Aftermarket Inc. website.
6 .3 Refrigerant ident ific at ion unit
6 .3.1 Refr igerant analysis
m
Oil contamination will damage the refrigerant identifica-
tion unit! If the refrigerant sample is supplied to the unit
from the recycling equipment directly, it must be pro-
tected from oil that comes from vehicles or accumulate
in service hoses!
m
The operator must periodically examine the test hose
and white sample filter for oil contamination and stop
immediately if any oil is observed!
t
If installed and enabled, Refrigerant Identification will
automatically occur anytime a Recycle or Internal Bottle
fill is performed.
t
The gas pressure should be between 1.7 –16 bar.
Accurate gas analysis can be achieved with less than
1.7 bar but additional time must be provided. In this
case start the flow of gas and then wait for 20 seconds
before instructing the refrigerant identification unit to
test the gas.
t
After sample is completed, ID results will be displayed on
ACX1180 screen.
t
If results show air percentage over 5%, check filter, hose
and coupler for any potential contamination or leaks
prior to repeating identification.
