A drain tubing (included) must be installed for all HRV units. For ERV units, it is not required, however, it is
recommended for climates where the outdoor temperature typically remains below -13°F, (over a 24-hour period)
for several days in a row, combined with an indoor humidity of 40% or higher.

CAUTION
Make a water trap loop in the tube to prevent the unit from
drawing unpleasant odors from the drain source. Make sure this
loop is located OVER the "T" as shown. Run the tube to the floor
drain or to an alternative drain pipe or pail.
IMPORTANT
If using a pail to collect water, locate the tube end approximately
1" from the top of the pail in order to prevent water from being
drawn back up into the unit.
