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.
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.
