Installation Instructions
4. Check for anything that could block airflow
Check area outside of window for things such as shrubs, trees, or awnings. Inside, be sure furniture, drapes, or blinds
will not stop proper air flow.
5. Check the available electrical service
Power supply must be the same as that shown on the unit serial
nameplate. (See Use & Care Guide for serial plate location.) Power
cord is 48″ long. Be sure you have an outlet near.
All models have a 3-prong service plug to provide proper service and
safe positive grouding. Do not change plug in any way. Do not use an
adapter plug. If your present wall outlet does not match your plug, call
a qualified electrician to make the needed change.

with covering to prevent scratches from unit. With the aid of an
assistant, remove unit from styrofoam base and rest on protected
surface. Move and install unit with the aid of an assistant. Save
