INSTALLATION INSTRUCTIONS
CONCENTRIC DIFFUSER
INSTALLATION
INSTRUCTIONS
1. The flex duct hanging from the unit should be close to the
ceiling opening for the diffuser, as shown at left. One or
two extra ceiling tiles must be removed in order to attach
diffuser and duct properly. The flex duct will allow for
some misalignment between the unit and the diffuser.
3. Make sure that the concentric diffuser is installed as
shown in the picture at the right for proper support.
2. (Before installing diffuser make sure that the four small
chains with turn buckles are in position.) Insert the
diffuser through the opening where it will be located
and aligned on the T-Bars. Attach the flex duct or sheet
metal duct and hanger chains to remove any strain on
the T-Bars.
Warning: Be sure supply opening is located
under supply opening on the A/C Unit.
