Installation
2.7.2Ducted Applications
For ducted applications on units, the duct work may be attached to the top perimeter of the unit. Refer to Figure 2 for information on upflow units and to Figure 3 for downflow units.
The duct work on upflow units must allow access to the motors/blowers for maintenance. The duct work on upflow units must be designed within the capacity of the unit, otherwise air flow and perfor- mance will be compromised.
2.7.3Plenum Installation
A solid plenum or plenum with discharge grille(s) may be installed. The plenum and instructions for its installation ship separately from the unit.
