threaded pipe or similar device to clear any excess paint

accumulated inside this fitting may ease final drain line 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.
