Important:
For optimal performance of your HRV or ERV,
the installation of an optional 6" round galvanized backdraft
damper is required on the fresh-air-to-home duct work. When
Exhaust and Supply in the Return
When using this installation, make sure that there is
minimum of 3 feet (0.9m) between the fresh air
and exhaust air connections of the HRV/ERV in
the return air duct. See Figure 3. Make sure
when using this installation that the fresh air duct
connection to the forced-air system return air
duct is not less than 10ft (3 m) upstream of the
return plenum connection to the forced air system.
Check with your local code or the forced air system's
manufacturer. The HRV and forced-air system must be
set to operate in continuous mode to achieve maximum
comfort and to avoid cross-contamination.
Note to installer:
Dwellings with multiple forced-air
systems require one HRV/ERV per system.
Ensure the unit runs in conjunction with forced-air system.
Refer to wiring diagram for furnace interlock instructions.

your local building codes or the manufacturer of the forced-air system.

Important:
The duct bringing outdoor air to the return air
plenum must be equipped with a manual damper to balance the
outdoor airflow.
Important:
Building and combus-
tion appliance installation codes
do not allow return air grilles or
openings such as "breather tee" or
indirect connections in an enclosed
room that is susceptible to spillage of
combustion appliances.
performing duct connections, always use approved tools
and materials. Also use steel duct connections for this
type of installation.
Finding a Suitable Installation Location
The HRV/ERV unit should be installed in a mechanical room
or as close to an outside wall as possible. This would ensure
a short run of insulated flexible duct.
The HRV/ERV unit must always be installed in an area where
the air is tempered to avoid freezing of the condensate
line. The contractor should install the unit in an area that
is accessible to allow the homeowner easy access for for
performing maintenance.
It is very important to install an electric receptacle (120VAC)
near the HRV/ERV. A separate circuit breaker is also recom-
mended. Installing the HRV/ERV close to a drain for the
condensate would avoid the need for a condensate pump.
