2460 Closable lead-through
The cap of the closable lead-through must be detached for installation and seal
maintenance by pressing the spring indicated by the arrow in with, for instance, a
screwdriver. Take care not to let the screwdriver slip as the spring is very stiff. Hold
the cap with your other hand when pressing in the spring. When the spring is down,
pull the cap gently out of the frame. When assembling the lead-through, ensure
that the order of the parts is correct. Also make sure that the spring goes in the
correct hole in the cap. Otherwise, the lead-through cannot be closed.
Maintenance
To keep the seals from hardening, lubricate
them yearly with a heat-resistant petroleum
jelly.
