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.

Pressure and Boiling Point
The boiling point given in tables for a liquid is always
referenced to an atmospheric pressure of 1 bar (14.5 psi). If
the pressure acting on a fluid changes, its boiling point also
changes.
For example, water boils at a lower temperatur ...
