The HRV cabinet has pre-punched holes for the drain. 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.

Installation Steps:
1.
Insert the drain spout through the hole in the drain pan. For the RCN4-TPD/TPF units, use the drain
spout with the foam gasket only.
2.
Install nut and washer on the drain spout. Tighten the nut. For the RCN4-TPD/TPF units, hand-tighten
the nut only.
3.
Construct a P-trap using the plastic tee connector.
4.
Cut two lengths of 1/2 in. drain hose (not included) and connect the ends to the two drain spouts and
the other ends to the plastic tee connector.
5.
Position the tee connector to point upward and connect the drain line. Use a zip tie to secure the drain
line to one of the 1/2 in. drain hoses.
6.
Tape or fasten base to avoid any kinks.
7.
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 odours from being drawn up the hose and into the fresh air supply of the
HRV.
Caution
•
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.
•
Drain trap and tubing must be below bottom of door with 1/4 in. per foot downwards slope away
from unit.
•
Under certain conditions, a secondary drain pan may be required to protect from condensate
leakage.
