UPFLOW APPLICATIONS
1. Collector Box Drain, Inducer Housing Drain, Relief Port, and
Pressure Switch Tubes
These tubes should be factory attached to condensate trap and
pressure switch ready for use in UPFLOW applications. These
tubes can be identified by their connection location and also
by a color label on each tube. These tubes are identified as
follows: collector box drain tube (blue label), inducer housing
drain tube (violet label or molded), relief port tube (green
label), and pressure switch tube (pink label).
2. Condensate Trap Drain Tube
The condensate trap drain connection must be extended for
field attachment by doing the following:
a. Determine location of field drain connection. (See Fig. 2 or
5.)
NOTE: If internal filter is used, drain tube should be located to
opposite side of casing of return duct attachment to assist in filter
removal.
b. Remove and discard casing drain hole plug button from
desired side.
c. Install drain tube coupling grommet (factory-supplied in
loose parts bag) in selected casing hole.
d. Slide drain tube coupling (factory-supplied in loose parts
bag) through grommet so long end of coupling faces
blower.

e. Cement 2 factory-supplied 1/2-in. street CPVC elbows to
rigid drain tube connection on condensate trap. (See Fig. 5.)
These elbows must be cemented together and cemented to
condensate trap drain connection.
NOTE: Failure to use CPVC elbows may allow drain to kink,
preventing draining.
f. Connect larger diameter drain tube and clamp (factory-
supplied in loose parts bag) to condensate trap and clamp
securely.
g. Route tube to coupling and cut to appropriate length.
h. Attach tube to coupling and clamp securely.
CONDENSATE TRAP LOCATION (ALTERNATE UPFLOW
ORIENTATION)
An alternate location for the condensate trap is the left-hand side
of casing. (See Fig. 2 and 6.)
NOTE: If the alternate left-hand side of casing location is used,
the factory-connected drain and relief port tubes must be discon-
nected and modified for attachment. See Condensate Trap Tubing
(Alternate Upflow Orientation) section for tubing attachment.
To relocate condensate trap to the left-hand side, perform the
following:
1. Remove 3 tubes connected to condensate trap.
2. Remove trap from blower shelf by gently pushing tabs inward
and rotating trap.
