9 Installation at a later date
You can add cables to the fire protection duct system PYROLINE
®
Rapid
at any time. To prevent harm to the cables during routing, we recommend
opening the duct route at as many points as possible and laying the
cables, rather than pulling the cables along long duct routes. See also
“4.6 Routing cables” on page 21.
Here is how to install cables at a later date:
• Dismantle connectors and fittings.
• Open the duct lid.
• Insert cables.
• Attach the duct lid firmly.
• Attach the connectors and fittings and screw them tight.
• Check the tightness.
• Check, and if necessary restore, the equipotential bonding along the
whole duct section.
