Conditioned Air Plenum Duct Connection Figure, 15
C60 Conditioned Air Plenum inside Box, Figure 16
NOTE: Set the conditioned air plenum inside the box or the
HMX frame so that water will be directed into the box
rather than to the outside. Seal outside edge at bottom of
plenum, see Figure 16.
NOTE: The conditioned air plenum is not insulated in the
factory. Insulate plenum after duct holes have been cut out.
In outside installations, the plenum should be fully insulated
and sealed to reduce air temperature increases within the
plenum. Any increase in the conditioned supply air
temperature will result in an increased building temperature
and run time.
NOTE: Barometric Dampers and /or building exhaust fans
are installed to relieve conditioned space pressure at the
highest temperature locations.
Barometric Damper Example, Figure 17

NOTE: Do not drill, cut, or compromise the powder coat
finish in the wet section or behind the HMX’s or drive
screws into filter areas or where internal wiring, soap
bottles, etc has been installed. See Figure 19
