Drain Pan
STEP 1: CUT OPENING IN GASKET
Remove an 8" portion of the weather seal gasket from the bottom left surface of the plenum.
To remove: Cut the gasket in the lower left corner of the plenum. Then make a second cut 8" from the left
corner. The gasket should peel away from the plenum leaving a clean mounting surface (See detail A).
STEP 2: SEAL AND SET PAN
Prior to placing the drain pan into the opening run a 1/4" bead of sealant the entire width of the removed
gasket. The secondary overow lip must extend into the plenum to prevent water leaks. The pan should
be mounted against the 3/4" ange of the plenum, refer to view A.
