4.1

Handling refrigerant R134a

Avoid all skin contact with the refrigerant.
The low boiling point of the refrigerant
(approx. -30 °C) can lead to frostbites.
Should it nevertheless come into contact
with the skin, remove any moistened
clothing immediately and rinse the affected
skin with copious 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 (malfunction),
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
respiratory system. If liquid refrigerant
comes into contact with the eyes, rinse them
thoroughly with water for 15 minutes. Then
obtain medical help even if no pain is felt.
R
Before connecting the ACS 810 to a vehicle air
conditioning system or an external refrigerant
cylinder, make sure the quick-release couplings are
not leaking.
R
Only ever use external refrigerant cylinders
provided with safety valves and certified in line
with the applicable standards.
R
Before switching off the ACS 810, make sure
all filling and drainage operations have been
completed. This prevents refrigerant escaping into
the environment.
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, lubricant,
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
smoking 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.
4.2

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 possible
transmission of current through the body.
R
De-energization is only to be performed by a qualified
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
components or exposed high-voltage wires before
deactivating the high-voltage vehicle electrical system.
