Instruction manual

V. SELECT AND INSTALL DUCTWORK
The design and installation of the duct system must be in
accordance with the standards of the NFPA for installation of
non-residence type air conditioning and ventilating systems, NFPA
90A or residence type, NFPA 90B and/or local codes and
ordinances.
Select and size ductwork, supply-air registers, and return air grilles
according to ASHRAE (American Society of Heating, Refrigera-
tion, and Air Conditioning Engineers) recommendations.
The unit has duct flanges on the supply- and return-air openings on
the side of the unit.
When designing and installing ductwork, consider the following:
WARNING: For vertical supply and return units, tools
or parts could drop into ductwork and cause serious injury
or death. Install a 90 degree turn in the return ductwork
between the unit and the conditioned space. If a 90 degree
elbow cannot be installed, then a grille of sufficient
strength and density should be installed to prevent objects
from falling into the conditioned space. Units with
electric heaters require 90 degree elbow in supply duct.
