Volkswagen Polo Service & Repair Manual: Handling Pressure Vessels
Secure vessels to prevent them falling over! |
Secure upright cylinders to stop them falling over and
cylinders lying flat to stop them rolling away. |
If dropped, the vessels could be so severely deformed that
they rupture. The refrigerant evaporates immediately, liberating
considerable force. Flying fragments of cylinders can cause
severe injuries. |
Valves may break off if cylinders are not properly
transported. To protect the valves, cylinders are only to be
transported with protective cap screwed on. |
Never store in the vicinity of radiators. |
High temperatures may occur next to radiators. High
temperatures are also accompanied by high pressures and the
maximum permissible vessel pressure may be exceeded. |
|
|
|
Not Warming Above 50 °C (122 °F)
To avoid possible risk, pressure vessel regulations specify that vessels are
not to be heated to in excess of 50 °C (122 °F).
Heating Warning
Do not heat with a naked flame under any circumstances.
Localized overheating can cause structural changes in the vessel
material, which then reduce its ability to withstand pressure.
There is also a danger of refrigerant decomposition due to
localized overheating. |
|
|
Empty Containers
Empty refrigerant vessels must always be sealed to prevent
the ingress of moisture. Moisture causes steel vessels to
corrode. This weakens the vessel walls. In addition, rust
particles entering into refrigeration systems from vessels will
cause malfunctioning. |
