- 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.
