* 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.

Condensate Piping for 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.
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 Tranquility Unit Isolation Pad to
minimize vibration transmission to the building structure.
