Safety Regulations For Working With Extraction And Charging Systems

- 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 be2.5sq.mm.
- In case of fire, remove external cylinder.
- Entrained oil from the air conditioning system drawn by the suction unit into the measurement vessel supplied is subsequently to be transferred to a sealed container, as it contains a small quantity of refrigerant which must not be released into the environment.
- Following shutdown, A/C service station is to be secured to stop it rolling away.
