NOTE Retro-Fitting Vertical Rod Devices:

Before retro-fitting an electric latch assembly into a
vertical device, the following must be done to ensure
proper alignment. Disconnect the vertical rods from
the device head. Install the electric latch assembly
as shown above. Once the ELR is properly installed
energize it so that the push pad is dogged down, by
doing so it will allow for proper alignment for the
vertical rods. Finally reconnect the vertical rods to
the device and make the proper adjusments.
