Safety points for Harpenden customers
If a spring has broken, a cable has come off or the door hangs crooked, stop using it, keep people and pets clear and do not try to force it open or closed. Leave the operator unplugged until the engineer has checked it.
Operators normally run from a switched fused spur; adding one to an existing circuit is not notifiable in England, but a new circuit falls under Part P.
