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.

The HRV and all condensate lines must

be installed in a space where the

temperature is maintained above the

freezing point or freeze protection must be

provided.
