NOTICE TO RIGGERS

Fig. 7 — Area Not To Be Drilled
• A 90-degree elbow must be used in the return duct or a
straight return duct must terminate with a grille securely
attached, so that if tools are dropped when working on the
unit, they will not enter the occupied psace.
• Units with electric heat require a 1-in. clearance for the
first 24 in. of ductwork.
• Outlet grilles must not lie directly below unit discharge.
Failure to follow these instructions on clearances and
90-degree ductwork and the location of outlet grilles could
result in personal injury and property damage from fall-
ing objects.
