and that the intake hood is at least 6 feet (1.8m) away from any of
the following:
• Exhaust hood

CAUTION
A drain tubing (included) must be installed for all HRV units. It is not required for ERV units, however, it is recom-
mended in climates where the outdoor temperature can remain below -25°C (-13°F) over a 24-hour period for
several days in a row, combined with an indoor humidity of 40% or higher.
1. Cut 2 sections of plastic tubing of at least 16” each.
2. Connect each one of them to the drain fittings located under the unit.
If installing a drain on an ERV unit, remove both drain plugs inside the unit
before installing the tubing.
3. Join their other ends to the «T» junction and remaining tubing as illustrated. This
will prevent the unit from drawing unpleasant odors from the drain source.
4. Run the tube to the floor drain or to an alternative drain pipe or pail. If using a
pail to collect water, locate the tube end approximately 1” into the pail in order to
prevent water from being drawn back into the unit.
