Other Features
Ventilation Control
The ventilation control lever is located at the upper left
side of the unit, behind the front grille.
This knob is set to CLOSE at the factory. When in this
position, the vent door is closed and only indoor air is cir-
culated by the air conditioner. Switching the knob to
OPEN opens the vent door to allow outdoor air to enter
the room. However, leaving the vent door at OPEN
reduces heating or cooling effectiveness and increases
operating costs.

Instructions.
