Drain Connection
The HRV may produce some condensation during a defrost cycle.
This water should flow into a nearby drain, or be taken away by a
condensatepump.
The HRV cabinet has prepunched holes for the drain (see below).
Insert the drain spout through the hole in the drain pan. Be sure to
install the "O ring" w hich seals each spout to the pan . HAND
TIGHTEN the washer and lock nut which hold the drain spout in
place.
Constructa P-Trap using the plastic tee connector. Cut two lengths
of 1/2" drain hose (not included) and connect the other ends to the
two drain spouts. Position the "T" fitting to point upward and
connectthe 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
supplyof the HRV.
