tube will exit.
Mount the trap externally to the bottom side of the unit using the
two screws provided in the location shown.
Cut the corrugated tube as shown in the illustration above.

Connect the 3/16" (4.8mm) ID relief tube to the middle port on the
trap. If an extension is required, use the 3/16" (4.8mm) OD flexible
tubing connector and the black 3/16" (4.8mm) ID relief tube in the
loose parts bag. Cut tube to length. Secure all connections with
clamps.
Cut an appropriate length of 2" (50.8mm) PVC pipe, long enough
to exit the cabinet and connect the vent drain to either:
• A standard field supplied 2" (50.8mm) PVC tee, or
• A 2" (50.8mm) PVC coupling fastened onto the drain tee.
Install tee trap into bottom section of tee.
Connect the tee trap and the main drain line exiting the casing as
shown in Figure 20.
Note: It is recommended that all PVC piping and fitting
connections be fit up and inspected before final cementing. Both
the external trap and the external tee trap must be primed
before operation, Verify all condensate drain connections are
securely clamped. A coupling and clamps (in loose part bag) may
be installed as shown for future servicing of the vent system.
