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.

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).
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).
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.
