Cut an appropriate length of 2" (50.8mm) PVC pipe, fittings and
extension 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.
Important: The pipe to the tee trap must be level or sloping towards
the tee trap.
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.
