Step 3—Information Plate—WeatherMaker™
The information plate is secured to the front of the control box and
provides a cover for it. (See Fig. 9.) This plate also provides a
surface to attach the wiring schematic, superheat-charging tables
with instructions, and warning labels. The plate has 2 tabs on the
top edge that are bent down at slightly more than 90°. When the
information plate is removed, these tabs can be inserted into 2
mating slots in the bottom-front edge of the control box, and the
plate will hang down, forming a lower front panel. (See Fig. 10.)
This is convenient where access to the controls is required while
the unit is operating. The information plate on the small size casing
completely covers the opening below the control box. On larger
models, the information plate may not cover the entire opening. In
this instance, the top cover can be removed and placed on its side
to cover the additional space.

This panel contains much of the same information as the informa-
tion plate mentioned previously, but is designed only to cover the
control box.
