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

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 baffle
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.
Install condensate trap at each unit with the top of the trap
positioned below the unit condensate drain connection as
shown in Figure 10. Design the depth of the trap (water-
seal) based upon the amount of ESP capability of the
blower (where 2 inches [51mm] of ESP capability requires
2 inches [51mm] of trap depth).As a general rule, 1-1/2
inch [38mm] trap depth is the minimum.
Always vent the condensate line when dirt or air can
collect in the line or a long horizontal drain line is required.
Also vent when large units are working against higher
external static pressure than other units connected
to the same condensate main since this may cause
poor drainage for all units on the line.
WHEN A VENT
IS INSTALLED IN THE DRAIN LINE, IT MUST BE
LOCATED AFTER THE TRAP IN THE DIRECTION OF
THE CONDENSATE FLOW.
Each unit must be installed with its own individual vent
(where necessary) and a means to flush or blow out the
condensate drain line. Do not install units with a common
trap and/or vent.
Condensate drain connection is a rubber coupling that
couples to 3/4” schedule 40/80 PVC. Use hose clamps to
secure the pipe inside the coupling. If the connection is
not secure, the connection may leak.
Instructions for coupling the condensate drain to the trap
are included in the bag that includes the coupling and
hose clamps.
Notice! Units with clear plastic drain lines should have
regular maintenance (as required) to avoid buildup of
debris, especially in new construction.
