R The ACS 611 must be constantly monitored when
in operation. Never leave the ACS 611 unattended
when in operation.
R The vehicle A/C service using the ACS 611 must
be prepared and implemented so that the vehicle
air conditioner circuit does not have to be opened
(forexample by removing the radiator or engine).
R Position the ACS 611 on all four wheels on a flat,
vibration-proof surface so that proper operation
ofthe scales is guaranteed.
R The ACS 611 can be secured in position by locking
the brake.
R The ACS 611 must always be transported in its
operating position. Never lay the ACS 611 on its
side, as oil could then escape from the vacuum
pump, or the built-in compressor could be damaged.
R There are no additional safety systems for protecting
the ACS 611 against damage resulting from natural
catastrophes.
R Never remove any components from inside the
ACS 611 except for maintenance or repair purposes.
R Observe the pertinent legal regulations or directives
to ensure safe handling of pressurized devices.
R We recommend calibrating the scales and pressure
sensors at least once per year. Contact customer
service for calibrating the scales of the internal
refrigerant cylinder.
R Never perform any maintenance work which is not
expressly recommended in this manual. Contact
customer service if components have to be replaced
other than in the course of maintenance work.
R ACS 611 must be connected to a properly grounded
electrical connection.
R If damage to the ACS 611 is established, terminate
usage immediately and contact customer service.
R The service hoses and quick-release couplings
must be regularly checked for wear and replaced
ifdamaged.
R The ACS 611 must be operated in an environment
corresponding to the directive BGR 157 with respect
to the exchange of air.
R Observe local laws or directives so as to ensure the
safety of the pressurized device.
R For safety reasons it is advisable to use a residual
current operated circuit breaker (rccb) with the
following specifications:
Parameters Specification
Rated voltage
230 VAC ± 10 %

2.5 Safety devices
Description Operation
Pressure switch Switches the compressor off if the normal
operating pressure is exceeded.
Safety valve The safety valve opens if the design
pressure is exceeded.
Fuse
Interrupts the power supply if overcurrent
is applied to the ACS 611.
Vents
The ACS 611 is provided with vents in
the bottom of the housing to ensure the
exchange of air even when switched off.
