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

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.
