Sound Attenuation for Vertical Units

Sound attenuation is achieved by enclosing the unit within a

small mechanical room or a closet. Additional measures for

sound control include the following:

If free return, mount the unit so that the return air inlet

is 90° to the return air grille (refer to Figure 2). Install a

sound baffle as illustrated to reduce line-of sight sound

transmitted through return air grilles.

Mount the unit on a Unit Isolation Pad to minimize

vibration transmission to the building structure. For more

information on Unit Isolation Pads, contact your distributor.
