3.1 Application
ACX1281 is suitable for vehicles with a conventional engine as
well as for hybrid and electric vehicles. ACX1281 features all the
functions required for vehicle A/C service.
The following functions can be implemented:
y Refrigerant recovery and recharging.
y
Refrigerant conditioning.
y Vacuum generation.
y
Flushing.
y
Refrigerant identification.
m
The ACX1281 can only be operated with R1234yf. The
ACX1281 is not to be used for service work on vehicles with
air conditioning systems employing refrigerants other than
R1234yf, as this will cause damage. Prior to A/C service
check the type of refrigerant used in the vehicle air condition-
ing system.

Description Function
Housing switch If one of the covers is removed from the ACX1281,
all operations are terminated and the ACX1281 is
disabled until the removed cover has been re-at-
tached to the ACX1281.
Service door switch If the service door of the ACX1281 is removed, the
ACX1281 stops all processes and starts service
mode. The built-in ventilation fan remains in opera-
tion to ensure that any R1234yf vapors which may
have accumulated in the ACX1281 housing (e. g.
on replacing the dry filter) are extracted from the
service area.
Air flow sensor The ACX1281 contains an air flow sensor which
detects whether or not there is a sufficient flow of
air in the housing of the ACX1281.
Safety shut-off
valves of internal
bottle:
The ACX1281 is provided with automatic safe-
ty shut-off valves at the internal refrigerant bottle.
Whenever a process is interrupted or covers/serv-
ice doors have been removed, the valves of the in-
ternal bottle close prevent R1234yf refrigerant es-
caping from the internal refrigerant bottle.
The safety shut-off valves are closed when the
ACX1281 is not active.
Pressure switch Switches the compressor off if the normal operat-
ing pressure is exceeded.
Safety valve The safety valve opens if the design pressure is ex-
ceeded.
Circuit breaker Interrupts the power supply if overcurrent is applied
to the ACX1281.
Vents The ACX1281 is provided with vents in the bottom
of the housing to ensure the exchange of air even
when switched off.
