2.4 Safety regulationsAlways carefully read and observe all the safety regulations before using the Bosch product.

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 Avoid all skin contact with the UV dye. 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, 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 help even if no pain is felt.

R Never swallow UV dye. If swallowed inadvertently, never attempt to induce vomiting. Drink copious amounts of water and obtain medical help.

R Before connecting the ACS 611 to a vehicle air conditioner or an external refrigerant cylinder, make sure the quick-release couplings are not leaking. Only ever use external refrigerant cylinders provided with safety valves and certified in line with the applicable standards.

R Before switching off the ACS 611, make sure all filling and drainage operations have been completed. This prevents refrigerant 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 damage or injury.

R Refrigerant extracted from a vehicle air conditioner 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 could damage the vehicle air conditioner.

If high-voltage components or high-voltage wires are inappropriately 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.


Symbols used | ACS 611 | 37 en

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 (for example 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 of the 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 if damaged.

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 % Rated frequency 50/60 HzRated current 230 VAC 6,3 A Rated tripping current 30 mATripping switch C

7.3 Manual service

i The service parameters (vacuum generation time, recharge quantity and oil type) can be found in the owner's manual or the vehicle repair manual.

i With the ACS 611 all service phases can be performed manually.

i Individual service phases are linked as standard to other service phases as they are needed to fully implement the individual operation selected.

i R134a can only be added to an air conditioner under vacuum. The vacuum phase must therefore be implemented before filling with R134a.

i Observe the vehicle-specific information before altering the quantity of oil.

7.3.1 Filling of refrigerant, fresh oil and UV dye

i Fresh oil and UV dye can only be added to an air conditioning system under vacuum. A vacuum must be generated prior to the oil/UV dye filling process.

i If pressure is detected in the vehicle air conditioning system during filling, recovery must be implemented in order to continue.

i Fresh oil and UV dye can only be added in conjunction with R134a.

! Always observe the vehicle manufacturer's instructions before altering the oil quantity.

! Before filling with UV dye it is essential to check whether leak testing of the air conditioning system with UV dye is approved by the vehicle manufacturer.

! Filling should, if possible, only occur via the high pressure connection. For systems that have only one low-pressure connection, at least 10 minutes must pass after filling before the vehicle air conditioning system can be switched on.
