Instructions
Installation instructions for the LGSs are presented
in the following two sections:
− Section 1 applies to mounting the
terminal unit.
− Section 2 applies to actuation.
Section 1 – Mounting
NOTE: These instructions include the use of angle
iron hangers or hanger brackets for
installation. These materials are merely for
suggested methods of installation; they are
not required.
1. Move the terminal to the installation area.
Remove the terminal from the shipping package.
Do not handle the Flo-Cross

Sensors, damper
extension rod, or any controls. Terminal
measurements and weights (with and without
heating coils), and coil connection information is
included in Figures 1 through 6, Table 1, and
Table 2.
NOTE: The terminal’s round collar must be
positioned as the supply inlet. If a controls
enclosure is attached to the terminal, the
controls enclosure must be mounted
vertically.
