Install the Internal Drain
Location of the Drain in the Cabinet Bottom
1. The Drain Kit must be installed on the bottom of
the wall sleeve prior to installation of the sleeve in
the wall. The location should not be in the area of
chassis supports or molded ribs (molded sleeve
only).
NOTE: If installation in the wall requires the use of a
sub-base, the location of the drain should be at least
3" from the front edge of the wall sleeve.
2. After location of Drain Kit is determined, locate and
drill 3 holes per dimensions on Fig. 3. The steel
mounting plate with the 1/2" center hole can also be
used as a template to mark holes. Repaint edges
of drilled holes on metal cabinet to prevent rust or
corrosion.
1-3/8"
3. The gasket should be placed on the steel mounting
plate (with 1/2" hole) with screw holes in gasket
lined up with screw holes in steel mounting plate.
Then insert drain tube through gasket and steel
mounting plate, as shown in Fig. 4.
