(

)
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 32°F and under 149°F.
Stale air is exhausted outdoors. Fresh air from outdoors
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 ( A ) and open the door. Discard the styrofoam
fillers (only in ERV units) 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.

OCATING THE

Choose an appropriate location for the unit.
• Within an area of the house where the ambient temperature is kept between 65°F and 104°F .
• So as to provide easy access to the interior of the unit, for quarterly 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).
• For HRV units ONLY: Close to a drain. If no drain is close by, use a pail to collect run-off.

All these units are equipped with 2 ports having integrated balancing damper. Turn the thumb screw
( B ) clockwise to manually open and adjust the damper ( C ). Set both Fresh air to building port and
Exhaust air to outdoors port to wide open position.
HRV units : Set the Fresh air to building port to wide open position, and adjust the Exhaust air
to outdoors port to 3rd notch.
NOTE: If the unit needs to be balanced, adjust the damper of the Exhaust air to outdoors port to
wide open position. See Section 7.
ERV units : Set both Fresh air to building port and Exhaust air to outdoors port to wide open
position.
