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:

1. Mount the unit so that the return air inlet is 0° to

the return air grille. Refer to Figure . Install a sound

baffle as illustrated to reduce line-of sight sound

transmitted through return air grilles.

. Mount the unit on a rubber or neoprene isolation pad to

minimize vibration transmission to the building structure.

VERTICAL INSTALLATION

Condensate Piping – Vertical Units

Vertical units utilize a condensate hose inside the

cabinet as a trapping loop; therefore an external trap

is not necessary. Figure 10a shows typical condensate

connections. Figure 10b illustrates the internal trap for

a typical vertical heat pump. Each unit must be installed

with its own individual vent and a means to flush or blow

out the condensate drain line. Do not install units with a

common trap and/or vent.
