Vertical Installation, Cont’d.
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 bafe
as illustrated to reduce line-of sight sound transmitted
through return air grilles.
2. Mount the unit on a rubber or neoprene isolation pad
to minimize vibration transmission to the building
structure.

Condensate Piping for Vertical Units - A condensate
line must be installed and pitched away from the unit to
allow for proper drainage. This connection must meet
all local plumbing/building codes. 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 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.

Notice! Units with clear plastic drain lines should have
regular maintenance (as required) to avoid buildup of
debris, especially in new construction.
