17. On some units, the return damper does not reach to
the top of the horizontal return opening in the unit. In
this case, a horizontal blank- off must be installed.
Install the horizontal blank- off at the top of the
horizontal return opening (See Fig. 25). Screw in
place through pre- punched holes.
18. When the W7220 EconoMi$er controller is shipped,
it is mounted to a steel bracket. This bracket is not
used, so remove and discard it. The controller is also
shipped with two harnesses, which will not be used,
so disconnect them from the W7220 and discard
them.
19. Install the controller in the top left corner of the unit
control box as show in the wiring diagram (See Fig.
78 and 79). Attach it with 2 screws.
20. The harness that connects to relays to the right side of
the W7220 is screwed to the control box (part number
40QQHSRSA—A20). Install this per wiring diagram
(See Figs. 78 and 79).
21. Connect all connectors on left side of the W7220 to
the corresponding terminals per the wiring diagram
(See Figs. 78 and 79).
