2.3 SIMPLIFIED INSTALLATION (CONNECTION TO A FORCED AIR SYSTEM)

2. TYPICAL INSTALLATIONS

Installations may vary according to the type of unit and the ports configuration (top or sides). Use the following illustrations as guidelines
to help you decide on how the unit will be installed.

All the units should be hung from the joists.
In every case, bathroom fans and a range hood should be used to exhaust stale air. Also, for homes with more than one level, we

recommend one exhaust register at the highest level.
There are 3 installation methods: Fully ducted, Central Draw Point and Simplified Installation.
NOTE: An electrical outlet has to be available within 3 feet of the unit.

2.1 FULLY DUCTED SYSTEM (PRIMARILY FOR HOMES WITH RADIANT HOT WATER OR ELECTRIC BASEBOARD HEATING.)

2.2 C

ENTRAL DRAW POINT (CONNECTION TO A FORCED AIR SYSTEM.)

For this type of installation, it is not essential that the forced air system
blower runs when the unit is in operation, but we recommend it.

NOTE: Home with multiple forced air systems should have one unit on

each system.

Stale air coming from the registers located at the highest level of the house
is exhausted to the outside. Fresh air from outside is filtered and supplied
by the register located in the lowest liveable level.
Homes with more than one level require at least one exhaust register at the
highest level.
See figure at right.

Stale air coming from the registers located at the highest level of the house
is exhausted to the outside. Fresh air from outside is filtered and supplied
to the return (plenum) or the supply duct of the forced air unit. See figure
at right.

Stale air is exhausted to the outside. Fresh air from outside is filtered and
supplied to the return (plenum) or the supply duct of the forced air unit. See
figure at right.
NOTE: It is possible to connect the outside fresh air duct to the supply

duct of the forced air unit.To do so, the Automatic fresh air bypass
must be used (part #: 15391). (See installation sheet included with
the Automatic fresh air bypass).

To avoid cross-contamination and achieve the highest efficiencies, the
Automatic fresh air bypass (part #15391) must be installed. If not, the
f

orced air system blower must always be ON.

NOTE: Home with multiple forced air systems should have one unit on

each system.

2. TYPICAL INSTALLATIONS (CONT’D)

The ERV units are created to meet specific requirements related to geographical locations. Take a look at the map below; the shaded
area shows the limits where the ERV unit can be installed. However, there is no geographical limitation for installing an HRV unit.

NOTE:The ERV unit is designed to assist in the management of humidity introduced into the home.

During cooling season, in extreme humidity conditions, the use of additional dehumidification unit may be required to quickly
remove all excess moisture. During heating season, in extreme dryness conditions, the use of a humidifier may be required if
the indoor air is still too dry.

2.4 INSTALLATION FOR ERV UNITS ONLY

2.4.1 GEOGRAPHICAL LOCATION

All 3 types of installations can be used in the attic (Fully ducted system, Central Draw Point or Simplified). The example shown below is
a Simplified installation (connection to a forced air system).

Stale air is exhausted to the outside. Fresh air from outside is filtered
and supplied to the return (plenum) of the forced air unit. See figure
at right.
NOTE: It is possible to connect the outside fresh air duct to the supply

duct of the forced air unit. To do so, the Automatic fresh air
bypass must be used (part #: 15205). (See installation sheet

included with the Automatic fresh air bypass).
To avoid cross-contamination and achieve the highest efficiencies, the
Automatic fresh air bypass (part #15205) must be installed. If not, the
forced air system blower must always be ON.

NOTE: Home with multiple forced air systems should have 1 unit on each system.

Due to the potential temperature difference between the attic and the rest of the house, all unit ducts must be insulated.

CAUTION

The attic temperature must always be above 0°C (32°F).
