Installation Made Easy
Installing a horizontal unit inside a corridor to enhance sound attenuation provides value to duct design. Trane takes this
fact one step further.
The new GEH design offers same side return-air/supply-air access to the unit. This access is contained within the overall
dimension of the units length as shown in Figure 44. The duct access to the unit allows the unit to be installed closely
against a corridor wall, while at the same time eliminating space required for the duct design.
Most horizontal unit designs provide an opposite supply air from the return air arrangement, or an end supply arrangement
option. See Figure 45 for end-supply example. An end-supply design increases the overall unit length of the system to
accommodate a 90-degree duct turn. This not only requires added space, but also adds cost in both materials and installa-
tion.
Additional value to the design is acquired through the same side supply/return-air design. This design eliminates a require-
ment for a four sided service access. When installing the same side return/supply-air access, a brief 3-inch minimum is all
that is required between the unit and the wall.
