Extraction And Charging System Safety Regulations

WARNING: This page is about a different car, the 2014 Volkswagen Touareg, 2013 Volkswagen Touareg, 2012 Volkswagen Touareg, and 2011 Volkswagen Touareg. However, it is still accessible from the selected car via links, so may be relevant.

Make sure the shut-off valves are closed before connecting the charging system to the air conditioning system.
Make sure the process is finished before disconnecting the charging system from the A/C system. This prevents any refrigerant from escaping into the atmosphere.
Once the purified refrigerant from the charging system has been transferred to an external compressed-gas cylinder, close the hand shut-off valves at the cylinder and charging system.
Do not expose charging system to moisture or use it in a wet environment.
Disconnect from power supply before performing service work on the charging system.
Avoid using an extension cord to minimize the fire hazard. If the use of an extension cable is unavoidable, the minimum cross-section should be 2.5 mm² .
In case of fire, remove the external cylinder.
If oil is drawn away from the air conditioning system by the suction unit into the included measurement reservoir, be sure to transfer it to a sealable container afterward because it contains a small quantity of refrigerant. Refrigerant must not be released into the environment.
The A/C Service Station must be secured from rolling away when it is not being used.
