Drain Connection (HRV Only)
During a defrost cycle, the HRV may produce some
condensation. This water should flow into a nearby drain, or be
taken away by a condensate pump.
The HRV cabinet has prepunched holes for the drain (see
below). Insert the drain spout through the hole in the drain pan.
Do not forget the “O ring” which seals each spout to the pan
REMEMBER TO HAND TIGHTEN ONLY the washer and
lock nut which hold the drain spout in place.
Construct a P-Trap using the plastic tee connector. Cut two
lengths of hose and connect each piece to an end of the “T”
fitting, then connect the other ends to the two drain spouts.
Position the “T” fitting to point upward and connect the drain
line. Tape or fasten base to avoid any kinks. Pour a cup of water
into the drain pan of the HRV after the drain connection is
complete. This creates a water seal which will prevent odors
from being drawn up the hose and into the fresh air supply of
the HRV.
