ACX280

Always carefully study and follow all the safety regulations
before using the MAHLE product.
Avoid all skin contact with the refrigerant. The low
boiling point of the refrigerant (approx. –30 °C) can
lead to frostbite. Should refrigerant come into con-
tact with the skin, remove any moistened clothing
immediately and rinse the area of skin affected with
generous amounts of water.
Avoid all skin contact with the UV dye. Should UV dye come
y
into contact with the skin, remove any moistened clothing
immediately and rinse the area of skin affected with gener-
ous amounts of water.
y R1234yf is colorless, with weak characteristic smell and
heavier than air. It may flow into repair pits. Should refriger-
ant escape, provide for sufficient ventilation (particularly in
repair pits) and leave the workshop.
Never inhale refrigerant, dye and oil vapors. The
vapors can irritate the eyes, nose and respiratory
system. If liquid refrigerant or UV dye comes into
contact with the eyes, rinse them thoroughly with
water for 15 minutes. Then obtain medical attention
even if no pain is felt.
y Never swallow UV dye. Should it be swallowed inadvert-
ently, never attempt to induce vomiting. Drink generous
amounts of water and obtain medical attention.
y Before connecting the ACX280 to a vehicle air condition-
ing system or an external refrigerant bottle, make sure the
quick-release couplings are not leaking. Only ever use
external refrigerant bottles provided with safety valves and
certified inline with the applicable standards.
y Before switching off the ACX280, make sure all charg-
ing and drainage operations have been completed. This
prevents damage to the unit and reduces risk of refrigerant
escaping into the environment.
Never use compressed air with R1234yf. Certain mix-
tures of air and R1234yf are highly flammable. Such
mixtures are a potential hazard and may lead to fire or
explosions and thus cause damage or injury.
Refrigerant extracted from a vehicle air conditioning system
y
may be contaminated with moisture, lubricant, dirt and
traces of other gases.
y The ACX280 is provided with a refrigerant identification system
designed to prevent contamination with other refrigerants.

If the refrigerant has been contaminated by being mixed
y
with other gases, remove the contaminated refrigerant and
add fresh R1234yf before using the ACX280 for A/C service.
y R1234yf is not to be used in areas in which there is a
danger of explosion. Fire, open flames and smoking are
prohibited. Welding and soldering are not permitted.
y The ACX280 unit should not be exposed to excess moisture
or be operated in wet areas.
y High temperatures and UV radiation may chemically sepa-
rate R1234yf. The resultant products can cause coughing
and nausea.
y R1234yf is not to be mixed with other refrigerants. The mix-
ing of refrigerants could damage the vehicle air conditioning
system.
If high-voltage components or high-voltage wires
are handled incorrectly, there is a risk of fatal injury
from high voltage and the possible transmission of
current through the body.
De-energizing is only to be performed by a qualified electri-
y
cian, a qualified electrician for specific tasks (hybrid) or a
power systems engineer.
Work on vehicles with high-voltage components is only
y
ever to be performed in a safe, de-energized condition by
persons with the minimum qualification "Trained to perform
electrical work".
y Even after deactivating a high-voltage vehicle electrical
system, the high-voltage battery may still be live.
y Operating condition cannot be established from any running
noise, as the electric machine is silent when stationary.
In gear positions "P" and "N" the engine or electric motor
y
may start spontaneously depending on the charge of the
high-voltage battery.
Never open or damage high-voltage batteries.
y
y On vehicles that have been in an accident, never touch high-
voltage components or exposed high-voltage wires before
deactivating the high-voltage vehicle electrical system.
The ACX280 must be constantly monitored when in opera-
y
tion. Never leave the ACX280 unattended when in operation.
y Vehicle A/C service using the ACX280 must be prepared
and implemented such that the vehicle air conditioning
system circuit does not have to be opened (for example by
removing the radiator or engine).
Position the ACX280 on all four wheels on a flat, vibration-
y
proof surface so that proper operation of the scales is
guaranteed.
The ACX280 can be secured in position by locking the
y
caster brake.
