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.
2.4.2 ERV U A
NITS TTIC
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).
NOTE: To get the most of your ERV unit, the ambient temperature around the unit should be conditioned. If the unit has to be installed in
an unconditioned space, the heat gains or losses from the unit and the ducts could increase the operation costs of the unit.
• Due to the potential temperature difference between the attic and the rest of the house, all unit ducts must be insulated.
• The attic temperature must always be above 0°C (32°F) and under 65°C (149°F).
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.
To avoid cross-contamination and achieve the highest efficiencies, the
forced air system blower must always be ON.
NOTE: Home with multiple forced air systems should have 1 unit on
each system.
