NSTALLATION
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.
CAUTION
• 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.

• Inspect the exterior of the unit for shipping damage. Ensure that there is no damage to the door, door latches, power cord, etc.
• Remove and discard both transport brackets (

fillers and remove the hardware kit from the unit. Inspect the interior of the unit for damage.
Ensure that heat or energy recovery core, core filters, insulation, dampers, etc. are all intact.

Choose an appropriate location for the unit.
• Within an area of the house where
the ambient temperature is kept between 18°C (65°F) and 40°C (104°F)
.
• So as to provide easy access to the interior of the unit, for semi-annual and annual maintenance.
• Close to an exterior wall, so as to limit the length of the insulated flexible duct to and from the unit.
• Away from hot chimneys and other fire hazards.
• Allow for a power source (standard 3-prong grounding outlet).
