Inspect the exterior of the unit for shipping damage. Ensure that there is no damage to the door, ports, power cord, etc.

3.2 LOCATING THE UNIT

Choose an appropriate location for the unit. UNIT HUNG BY CHAINS AND SPRINGS
• Within an area of the house where the ambient temperature is kept
between 10°C (50°F) and 40°C (104°F).
• Away from living areas (dining room, living room, bedroom), if possible.
• So as to provide easy access to the interior of the unit, for regular and
annual maintenance.
NOTE: There must be a 27” clearance in front of the unit to fully open
the door. In limited space, the door can be removed by lifting it
up, but there must be a 18” clearance in front of the unit to
remove the core.
• Close to an exterior wall, so as to limit the length of the insulated flexible
duct to and from the unit.
• Away from hot chimneys and other fire hazards.
• Allow for a power source (standard 3-prong grounding outlet).
• Close to a drain. If no drain is close by, use a pail to collect run-off.

3.3 PLANNING OF THE DUCTWORK

• Keep it simple. Plan for a minimum of bends and joints.
• Keep the length of insulated and non-insulated ducts to a minimum, because the length of the ductwork impacts directly the unit
airflow performances.
• Do not ventilate crawl spaces or cold rooms. Do not attempt to recover the exhaust air from a dryer or a range hood. This would cause
clogging of the filters and recovery module.
• If the house has two floors or more, be sure to plan for at least one exhaust register on the highest lived-in level.

3.4 DUCT SIZE

To determine the appropriate duct size to be used, refer to the ASHRAE or HRAI HANDBOOK. Below is an example of a design
for a fully ducted system with a unit having a high speed performance of 160 cfm.

3.5 INSTALLING THE DUCTWORK AND REGISTERS

3.5.1 FULLY DUCTED SYSTEM
! WARNING
Never install a stale air exhaust register in a closed room where a combustion device operates, such as a gas
furnace, a gas water heater or a fireplace.

Stale air exhaust ductwork

• Install the stale air exhaust registers where the contaminants are produced: kitchen, living room, etc. Position the registers as far
from the stairway as possible and in such a way that the air circulates in all the lived-in spaces in the house.
• If a register is installed in the kitchen, it must be located at least 4 feet (1.2 m) from the range.
• Install the registers 6 to 12 inches (152 to 305 mm) from the ceiling on an interior wall OR install them in the ceiling.
• If possible, measure the velocity of the air flowing through the registers. If the velocity is higher than 400 ft/min (122 m/min), then
the register type is too small. Replace with a larger one.
Fresh air distribution ductwork
• Install the fresh air distribution registers in bedrooms, dining rooms, living room and basement.
• Keep in mind that the fresh air registers must be located as far as possible from the stale air registers.
• Install the registers either in the ceiling or high on the walls with air flow directed towards the ceiling. (The cooler air will then cross
the upper part of the room and mix with room air, before descending to occupant’s level.)
• If a register must be floor installed, direct the airflow up the wall.

5. ELECTRICAL CONNECTION TO THE FURNACE

! WARNING
Never connect a 120-volt AC circuit to the terminals of the furnace interlock (standard wiring). Only use the low
voltage class 2 circuit of the furnace blower control.
For a furnace connected to a cooling system:
On some older thermostats, energizing the “R” and “G” terminals at the furnace has the effect of energizing “Y” at the thermostat and
thereby turning on the cooling system. If you identify this type of thermostat, you must use the ALTERNATE FURNACE INTERLOCK WIRING.
