INSTALLING THE DUCTWORK AND THE
REGISTERS
FULLY DUCTED SYSTEM (T-1)
This configuration allows Recirculation mode to operate.
A200562
Fig. 5 – Fully Ducted System
STALE AIR FROM BUILDING:
• 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 TO BUILDING:
• 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)
This configuration allows Recirculation mode to operate.
When performing duct connection to the furnace/AHU, installation must
be done in accordance with all applicable codes and standards. Please
refer to your local building code.
A200563
Fig. 6 – Exhaust Ducted System
STALE AIR FROM BUILDING:
• Same as for Fully Ducted System.
FRESH AIR TO BUILDING:
• Connect the fresh air distribution duct of the unit to the furnace/AHU
return duct at least 10 feet away from the furnace/AHU (A+B).
NOTE: This 10-ft. distance applies only in areas where the outside
temperature falls below the freezing point 0°C (32°F).
NOTE: The furnace/AHU blower operation can be synchronized with
the unit (CONNECTION TO THE CENTRAL FORCED-AIR SYSTEM
on p10). It is recommended, but not essential that the furnace/AHU
blower runs when the unit is in operation.
NOTE: For this type of configuration, the T-2 option must be selected
on the LCD screen when auto-balancing the unit.

WARNING
!
CARBON MONOXIDE HAZARD
Failure to follow this warning could result in serious personal injury or
death.
Never install stale air exhaust register in a room where there is a
combustion device, such as a gas furnace, a gas water heater or a
fireplace. A negative pressure could be created in the area of the fuel
burning unit and draw carbon monoxide into the room. CO can cause
personal injury or death.
CAUTION
!
PROPERTY DAMAGE HAZARD
If ducts have to go through an unconditioned space (e.g.attic), always
use insulated ducts to prevent condensation from forming inside and
outside ducts, which could cause material damage and/or mold growth.
Also, if fresh air to building duct and/or stale air from building duct
goes through an unconditioned space, the unit must be set to operate
continuously in cold conditions (below 10°C/50°F). Continuous air
movement inside ducts will prevent condensation formation. The unit
can be stopped temporarily for maintenance and/or repair purposes in
such conditions.
