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 condensate pump.
The HRV cabinet has a pre-punched hole for the
drain. Insert the drain spout through the hole in the
drain pan. Be sure to install the "O ring" which seals
each spout to the pan. HAND TIGHTEN the washer
and lock nut which hold the drain spout in place.
Make a loop in a length of 1/2" drain hose to
construct a P-Trap (drain hose not included). Ensure
that the loop is large enough to avoid kinks and
secure it with a zip tie (zip tie not included). Pour a
cup of water into the drain pan of the HRV after the
drain connection is complete. This creates a water
seal that prevents odors from being drawn up the
hose and into the fresh air supply of the HRV.
