3. INSTALLATION
When applicable local regulation comprises more restrictive installation and/or certification requirements, the
aforementioned requirements prevail on those of this document and the installer agrees to conform to these at
his own expenses.
When performing installation, servicing or cleaning the unit, it is recommended to wear safety glasses and gloves.

NSPECT THE
ONTENT OF THE
• Inspect the exterior of the unit for shipping damage. Make sure that there is no damage to the door, door latches, door hinges, dampers,
duct collars, cabinet, etc.
• Inspect the interior of the unit for damage. Make sure that the fan motor assembly, recovery module, insulation, dampers, condensation
tray are all intact.

OCATING AND
OUNTING THE UNIT
NOTE: Please note that these units can be installed in either the normal or reverse (upside down) position.
When installed in reverse postion (upside down) in a cold region where outside temperature could drop below
-20oC (-4oF) for more than 5 days in a row, the unit must always be set in extended defrost. See Section 4.1.2 Setting
Extended Defrost.
Choose an appropriate location for the unit:
• 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 cabinet for every three months and annual maintenance, and
to the control panel on the side of the unit;
• Close to an exterior wall, so as to limit the length of the insulated flexible duct to and from the unit
• Close to a drain. If no drain is close by, use a pail to collect run-off
• Away from hot chimneys, electrical panel and other fire hazards
• Allow for a power source (standard outlet)
Hang the unit with the 4 chains and springs provided (see illustrations at right).

LANNING OF THE
UCTWORK
a) Follow the instructions in Section 3.4 (next page) to determine the appropriate duct diameters for your system.
b) Keep it simple. Plan for a minimum number of bends and joints. Keep the length of insulated duct to a minimum.
c) Do not use wall cavities as ducts. Do not use branch lines smaller than 4" Ø (102 mm Ø).
d) 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 recovery module. Use sheet metal for the kitchen exhaust duct.
e) Be sure to plan for at least one exhaust register on the highest lived-in level of the house if it has 2 floors or more.
