The ACX1180 was designed with menu driven prompts on
the display to guide technician through the service setup.
The display shows data such as the internal cylinder weight
and prompts technician for input using the alphanumeric
keypad and various navigation buttons.
The ACX1180 can be used to perform a fully automatic A/C
service. The technician will be prompted for entry of data
such as charge amount and given options such as perform-
ing leak tests. Once necessary data has been entered, the
ACX1180 will automatically complete an A/C service and
alert the technician for interaction (if necessary) or when
complete.
The ACX1180 can be used to perform the individual
functions of an A/C service as well (Recycle, Vacuum or
Charge).
A setup routine can be used to select specific options, set
default values, perform maintenance operations and man-
age fluid capacities processed.
The refrigerant recovered from the air conditioning system
passes through the combo filter to remove suspended
particles and moisture.
The purpose of the vacuum pump is to generate a vacuum
in the air conditioning system which removes excess mois-
ture and to detect possible leaks in the vehicle air condition-
ing system.
Used oil separated from the vehicle refrigerant recovered
drains into the used oil bottle.
Oil removed from the vehicle A/C system compressor dur-
ing the recovery process should be manually injected into
the A/C system prior to recharging the system.
The vehicle air conditioning system is partly filled with UV
dye to facilitate the detection of leaks in the event of dam-
age to the vehicle air conditioning system.
The refrigerant in the internal refrigerant bottle is used for
filling the vehicle air conditioning system.
The purging unit for the non-condensable gases, consisting
of a temperature sensor, pressure sensor, coil and orifice,
always takes effect when the internal refrigerant bottle pres-
sure is higher than the saturation pressure.
Refrigerant identification is a menu-driven process imple-
mented by a refrigerant identification unit which is integrat-
ed into the ACX1180 (when option is turned on).
