Check the service hoses for damage.

Firmly connect the service quick-release
couplings to the service hoses.

Wear protective gloves.
t
Before the ACX1180 can be used, the internal
refrigerant bottle must be filled with liquid refrigerant. Use
only R134a refrigerant.
t
The refrigerant can be obtained from your gas supplier. It
can be stored normally and transported in bottles with con-
nection fittings.
t
To ensure a reliable procedure, it is advisable to use the
optimum quantity of refrigerant. The optimum quantity
of refrigerant for the ACX1180 is 10lbs (4.5kg) – 18lbs
(8.16kg).
t
An inadequate quantity may make efficient filling of the ve-
hicle air conditioning system impossible. Also, if there is an
insufficient quantity, the ACX1180 may not be able to oper-
ate efficiently. In the event of an excessive quantity, there
may not be sufficient space for the refrigerant recovered
from the vehicle air conditioning system.
m
Generally speaking, the actual quantity of refrigerant added
exceeds the set quantity to allow a dead weight in the
tank to keep the internal refrigerant circuit wetted. Add 1lb
(454g) to the set quantity when filling with refrigerant for
the first time.
1. To fill internal bottle, push until "FILL CYLINDER" is
displayed then press YES.
2. Follow the menu prompting.
t
The current pressure inside the external refrigerant bottle is
indicated on the low-pressure gauge.
t
Any amount of refrigerant between 6.6lb (3kg) and 24.2lb
(11kg) can be added.
m
Do not interrupt the automatic filling process prior to auto-
matic termination by the ACX1180.

Follow the instructions below for filling the internal
refrigerant bottle.
—
Ref rigerant bot t le w it h one valve:
Always turn the external refrigerant bottle upside
down when filling the internal refrigerant bottle.
—
Ref rigerant bot t le w it h t w o valves:
Use the adapter set to connect the service hose (LP)
to the external refrigerant bottle. In doing so, turn the
external refrigerant bottle such that the connections
are facing upwards.
m
The internal refrigerant bottle should only be replaced if it
is severely damaged. The internal refrigerant bottle must
always be filled using an external refrigerant bottle.
m
During filling, the external refrigerant bottle must be
firmly positioned and the operator must ensure that the
service hoses are safely routed to avoid the danger of
the external refrigerant bottle falling over.
