STALE AIR EXHAUST DUCTWORK:
• Install registers in areas where contaminants and humidity are
produced: kitchen, bathrooms, laundry room, etc.
• Install registers on an interior wall, 6 to 12 inches away from the
ceiling OR in the ceiling.
• Install the kitchen register at least 4 feet away from the range.
• Bathroom fans and range hoods can be used to better exhaust stale air.
• Homes with more than one level require at least one exhaust register
at the highest level.
FRESH AIR DISTRIBUTION DUCTWORK:
• Install registers in bedrooms, dining room, living room and basement.
• Install registers in the ceiling OR high on the walls with the airflow
directed towards the ceiling.
• If a register must be installed in the floor, direct airflow up the wall.
NOTE: For this type of configuration, the T-1 option must be selected
on the LCD screen when auto-balancing the unit.
EXHAUST DUCTED SYSTEM (T-2)

temperature falls below the freezing point 0°C (32°F).
