Install Vent Pipe grommet in side of casing.
Cut an appropriate length of 2" PVC pipe long enough to exit the
cabinet and connect the vent drain to either:
A standard field supplied 2" PVC tee (N9MP1 and 2 models),
or
A 2" PVC coupling fastened onto the Drain Tee (*9MPD mod-
els)
Install Tee trap into bottom of tee.

Install the black PVC drain connector (3/4" PVC x 1/2" CPVC from
loose parts bag) as shown in the illustration above.
Cut the black Drain Tube (5/8" ID - in loose parts bag) to length to
fit between Trap and tube connector through grommet.
Clamp both ends of the Drain Tube using clamps provided.
Glue the CPVC street elbow to the Trap using appropriate cleaner
and solvent cement.
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 in-
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.
