Extraction And Charging System Safety Regulations

Make sure the shut-off valves are closed before connecting the charging system to the air conditioning system.
Before disconnecting the charging system from the air conditioning system, make sure the charging process has been completed to stop refrigerant 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.
Never use an extension cable on account of 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.
Entrained oil from the air conditioning system drawn by the suction unit into the measurement container supplied is subsequently to be transferred to a sealed container as it contains a small quantity of refrigerant. It must not be released into the environment.
Following shutdown, the service station is to be secured to stop it rolling away.
