How to Operate the Damper

Adjust the ventilation level by shifting the
1
damper knob up or down.
Full opened
Closed
• Closing the damper reduces the temperature
rising time and saves electricity.
We recommend setting the damper knob at 0
unless using for ventilation or shortening the time
for the temperature to fall.
• When the damper is opened during operation
under high temperature, hot air spouts out from
the exhaust opening.
Be sure to make enough space between the back
surface and the wall. (Refer to page 4 "2. Choose
a proper place for installation")
• The exhaust opening and surrounding surface
becomes very hot.
Take care not to get burned.
• Opening the damper too much may prevent the
temperature from reaching the desired level due to
over-ventilation.
