Condensate Installation
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.
Pitch the unit toward the drain as shown
in Figure 2 to improve the condensate
drainage. Ensure that unit pitch does not
cause condensate leaks inside the cabinet.
Install condensate trap at each unit with
the top of the trap positioned below
the unit condensate drain connection
as shown in Figure 4. As a general rule,
the minimum depth for traps is 1-1/2
inches. Each unit must be installed with
its own individual trap and connection
to the condensate line (main) or riser.
Provide a means to flush or blow out the
condensate line. DO NOT install units
with a common trap and/or vent.

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.
Some applications will require condensate
pumping due to limited ceiling space or
the need to connect to a main drain line
higher in elevation. Condensate pumps
are to be field provided and are mounted
externally to the unit.
Units are provided with a 1/2" MPT
condensate connection. There is also a
condensate connection kit provided in
the unit which contains a flexible coupling
that can be used to connect to 3/4" PVC
or 1" Copper. Dispose of kit if not used.
See figure 5.
