Cut an appropriate length of 2² PVC pipe, long enough to exit the
cabinet and connect the vent drain to either:
· A standard field supplied 2² PVC tee (N9MP1 models), or
· A 2² PVC coupling fastened onto the Drain Tee (*9MPD
models)
Install Tee Trap into bottom section of Tee.
Connect the Tee trap and the main drain line exiting the casing as
shown in Figure 18.
Note: It is recommended that all PVC piping and fitting connec-
tions be fit up and inspected before final cementing. Both the ex-
ternal 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.
