3.5 CABINET INSTALLATION

1. Open the window. Mark a line on the center of the window

stool between the side window stop moldings. 
Loosely attach the sill bracket to the support bracket using
the carriage bolt and the lock nut. 

2. Attach the sill bracket to the window sill using the screws

(Type B).
Carefully place the cabinet on the window stool and align the
center mark on the bottom front with the center line marked
window stool.

3. Using the M-screw and the lock nut, attach the support

bracket to the cabinet track hole. Use the first track hole
after the sill bracket on the outer edge of the window sill.
Tighten the carriage bolt and the lock nut. Be sure the
cabinet slants outward. 

CAUTION: Do not drill a hole in the bottom pan. The unit is

designed to operate with approximately 1/2" of
water in bottom pan. 

4. Pull the bottom window sash down behind the Top retainer

bar until they meet.

NOTE: 1. Do not pull the window sash down so tightly that the

movement of Frame curtain is restricted. Attach the
cabinet to the window stool by driving the screws
(Type B) through the cabinet into window stool. 

2. The cabinet should be installed with a very slight tilt

downward toward the outside.
