Installation of unit
• Unit Installation
• When the air conditioner has been running and is turned off or set to the fan position, wait at least 3 minutes
before resetting to the cooling & heating operations.
Note
A slight heat odor may come from the unit when first switching to HEAT after the cooling season is over. This
odor, caused by fine dust particles on the heater, will disappear quickly. This is harmless.
• PTAC exhausting discharge air in balcony that is closed off with glass or panels.
This causes hot air to be pulled back into the Outdoor air intake.

In order to work correctly, installer or customer will have to remove glass panels to better exhaust hot air.
