The plugs are located in the ERV accessories bag. The plugs will be installed into
the two holes located in the bottom tray of the ERV. They must be inserted from
the inside of the unit to ensure the holes are fully sealed.
Installing Drain Plug (Optional)
IMPORTANT
In climates where the outdoor temperature remains above 13ºF (-25ºC) combined with an indoor humidity less than 30%, the use of a drain is
optional.

The ERV Dual Intake and Exhaust Hood Kit offers the benefit of requiring only one 6” (152 mm) hole in the exterior wall (as opposed
to two separate weatherhoods) to complete the connections for fresh air intake and stale air exhaust. The pressure drop/airflow
charts should be referred to when matching the Dual Intake and Exhaust Hood to the ERV. The Dual Intake and Exhaust Hood Kit is
compatible with 5” or 6” diameter duct.
