INSTALLATION
Step 1 — Unit Location —
The HRV must be located
in a heated space where it can be conveniently serviced.
Typically the HRV is located in the mechanical room or an area
close to the outside wall where the weather hoods will be
mounted. If a basement area is not convenient or does not
exist, a utility or laundry room may be used. See Fig. 2 for
dimensions.
Attic installations are not normally recommended due to the
complexity of work to install, freezing conditions in the attic,
and the difficulty of access for service and cleaning.
Connecting appliances to the HRV
is not recommended
(such as a clothes dryer, range top, stovetop fan, or central
vacuum system). These appliances may cause lint, dust or
grease to collect in the HRV, damaging the unit.
NOTE: Connecting any of these type of appliances to the
HRV will invalidate the warranty.
Locate the unit close to the outside wall on which the supply
and exhaust hoods will be mounted. There should be a nearby
power supply of 120 volts, 60 Hz available.
There should be access to a water drain for condensate
removal of the unit during defrost.
The unit should be located in a heated area (attic installation
is not recommended). The location should also minimize any
noise level that would be created by the unit in the living area.
Make sure there is adequate access for future maintenance.
Step 2 — Unit Mounting —
The unit is typically hung
from the ceiling for mounting. See Fig. 2 for unit dimensions.
Perform the following to mount the HRV:
1. Place fastening hooks on the strapping board or the
floor joists. See Fig. 3.
2. Attach a hanging chain (provided) to each no. 10

bolts (provided) on the top 4 corners of the unit and
tighten. See Fig. 4.
3. Hang the unit by slipping a link onto the hanging
hooks, making sure the unit is level. Unit condensate
will not drain properly unless unit is level. See Fig. 5.
