NOTE: If the power exhaust accessory is to be installed on the
unit, the hood shipped with the unit will not be used and must be
discarded. Save the aluminum filter for use in the power exhaust

hood. If the panel is still attached to the unit, remove the
screws along the sides and bottom of the panel. See
Fig. 15.
2. Swing out indoor coil access panel and insert the hood
sides under the panel (hood top). Be careful not to lift the
