VERTICAL INSTALLATION

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 90° to

the return air grille. Refer to Figure 9. Install a sound

bafﬂ e 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.

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 (where necessary) and a means to

ﬂ ush or blow out the condensate drain line. Do not install

units with a common trap and/or vent.

* Some units include a painted drain connection. Using a

threaded pipe or similar device to clear any excess paint

accumulated inside this fitting may ease final drain line installation.
