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.
2.
Mount the unit on a rubber or neoprene isolation pad to mini-
mize 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.

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