Volkswagen Polo Service & Repair Manual: Extraction and Charging System Safety Regulations
| 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. |
| 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 vessel 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, A/C service station is to be secured to
stop it rolling away. |

Secure vessels to prevent them falling over!
Secure upright cylinders to stop them falling over and
cylinders lying flat to stop them rolling away.
