2.4 Safety regulations
2.4.1 ACX1180
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 contact with the skin, remove any
moistened clothing immediately and rinse the
area of skin affected with generous amounts of
water.
y
Avoid all skin contact with the UV dye. Should UV dye
come into contact with the skin, remove any moistened
clothing immediately and rinse the area of skin affected
with generous amounts of water.
y
R134a is colorless, with weak characteristic smell and
heavier than air. It may flow into repair pits. Should re-
frigerant 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 ACX1180 to a vehicle air condi-
tioning 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 ACX1180, make sure all charg-
ing and drainage operations have been completed. This
prevents damage to the unit and reduces risk of refriger-
ant escaping into the environment.
Never use compressed air with R134a. Certain
mixtures of air and R134a are highly flammable.
Such mixtures are a potential hazard and may
lead to fire or explosions and thus cause dam-
age or injury.
y
Refrigerant extracted from a vehicle air conditioning
system may be contaminated with moisture, lubricant,
dirt and traces of other gases.
y
The ACX1180 is provided with a refrigerant identification
system designed to prevent contamination with other
refrigerants.
y
If the refrigerant has been contaminated by being mixed
with other gases, remove the contaminated refrigerant
and add fresh R134a before using the ACX1180 for A/C
service.
y
R134a 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
y
The ACX1180 unit should not be exposed to excess
moisture or be operated in wet areas.
y
R134a is not to be mixed with other refrigerants. The
mixing of refrigerants could damage the vehicle air con-
ditioning 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.
y
De-energizing is only to be performed by a qualified
electrician, a qualified electrician for specific tasks (hy-
brid) or a power systems engineer.
y
Work on vehicles with high-voltage components is only
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.
y
In gear positions "P" and "N" the engine or electric
motor may start spontaneously depending on the charge
of the high-voltage battery.
y
Never open or damage high-voltage batteries.
y
On vehicles that have been in an accident, never touch
high-voltage components or exposed high-voltage
wires before deactivating high-voltage vehicle electrical
system.
y
The ACX1180 must be constantly monitored when in
operation. Never leave the ACX1180 unattended when in
operation.
y
Vehicle A/C service using the ACX1180 must be pre-
pared and implemented such that the vehicle air condi-
tioning system circuit does not have to be opened (for
example by removing the radiator or engine).
y
Position the ACX1180 on all four wheels on a flat,
vibration-proof surface so that proper operation of the
scales is guaranteed.
y
The ACX1180 can be secured in position by locking the
caster brake.
y
The ACX1180 must always be transported in its operat-
ing position. Never lay the ACX1180 on its side, as oil
could then escape from the vacuum pump or the built in
compressor could be damaged.
