Rail Mounting
Rail Layout
•Rails designed to handle the weight of the APEX should be positioned as shown on the diagrams below (rails by others).
•Make sure that rail positioning does not interfere with the supply air discharge opening or the exhaust air intake opening on the APEX unit (see FIGURE 6).
•Rails should run the width of the unit and extend beyond the unit a minimum of 12 inches on each side (see FIGURE 5).
•Set unit on rails.

Weatherhoods
Supply weatherhood will be factory mounted. There are two exhaust weather hoods shipped separately as a kit with instructions on how to mount (refer to Page 7 for hood locations).
Dampers
Backdraft dampers are always included as an integral part of the exhaust hood assemblies. Motorized outdoor air and exhaust air dampers are optional and are factory mounted (and wired) at the inlet.
An optional motorized damper is also available for recirculation mode. This damper allows 100% recirculation of exhaust air through the coils for continued tempering of the space during unoccupied mode (i.e. no outdoor air being brought in). This damper is mounted and wired at the factory.
