Handling refrigerant R134a

Avoid all skin contact with the refrigerant.
The low boiling point of the refrigerant (ap-
prox. -30 °C) can lead to frostbites. Should
it nevertheless come into contact with the
skin, remove any moistened clothing imme-
diately and rinse the affected skin with copi-
ous amounts of water.
R
R134a is colorless, has a weak intrinsic odor and is
heavier than air. It displaces oxygen and may flow
into repair pits. Should refrigerant escape (malfunc-
tion), always ensure adequate ventilation and air
extraction (especially in pits). Exit the workshop.
Never inhale refrigerant and oil vapors. The
vapors can irritate the eyes, nose and respi-
ratory system. If liquid refrigerant comes
into contact with the eyes, rinse them thor-
oughly with water for 15 minutes. Then ob-
tain medical help even if no pain is felt.
R
Before connecting the ACS 810 to a vehicle air con-
ditioning system or an external refrigerant cylinder,
make sure the quick-release couplings are not leak-
ing.
R
Only ever use external refrigerant cylinders provided
with safety valves and certified in line with the ap-
plicable standards.
R
Before switching off the ACS 810, make sure all fill-
ing and drainage operations have been completed.
This prevents refrigerant escaping into the environ-
ment.
Do not use compressed air with R134a.
Some air mixtures with R134a are highly
flammable. Such mixtures are a potential
hazard and may lead to fire or explosions
and thus cause damage or injury.
R
Refrigerant extracted from a vehicle air conditioning
system may be contaminated with moisture, lubri-
cant, dirt and traces of other gases.

R
R134a is not to be used in areas in which there is a
danger of explosion. Fire, naked flames and smok-
ing are prohibited. Welding and soldering are not
permitted.
R
High temperatures and UV radiation may chemically
separate the R134a. The resultant products cause
coughing and nausea.
R
R134a is not to be mixed with other refrigerants.
The mixing of refrigerants can damage the vehicle air
conditioning system.

Working on the vehicle

If high-voltage components or high-voltage
wires are inexpertly handled, there is a risk of
fatal injury from high voltages and the possi-
ble transmission of current through the body.
R
De-energization is only to be performed by a quali-
fied electrician, a qualified electrician for specific
tasks (hybrid), or a power systems engineer.
R
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".
R
Even after deactivating the high-voltage vehicle
electrical system, the high-voltage battery may still
be live.
R
The operating condition cannot be established from
any running noise, as the electric machine is silent
when stationary.
R
In gear positions "P" and "N" the engine or electric
motor may start spontaneously depending on the
charge of the high-voltage battery.
R
Never open or damage high-voltage batteries.
R
On accident vehicles, never touch high-voltage com-
ponents or exposed high-voltage wires before deacti-
vating the high-voltage vehicle electrical system
