1. Check window opening size. The mounting parts
furnished with this air conditioner are made to install
in a wooden sill double-hung window. The standard
parts are for window dimensions listed above. Open
sash to a minimum of 19” (483mm).
2. Check condition of window. All wood parts of
window must be in good shape and able to firmly
hold the needed screws. If not, make repairs before
installing unit.
3. Check your storm windows. If the storm window
frame does not allow the clearance required, correct
by adding a piece of wood as shown in Figure 2-10,
or by removing storm window while room air
conditioner is being installed.
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.
