Drain Connection
The HRV cabinet has pre-punched holes for the drain, in order to keep the drain pan intact hand tighten the 2 plastic drain
tube to the unit using the gasket and nuts.
Cut two sections of ½" drain pipe and connect the other ends to the drain tube then connect to “ T ” connector. Connect a
drain line and create a
to prevent the unit from unpleasant odours from drain source. Tape or fasten base to avoid
P-trap
any bends.
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.

-
Fresh air intake and exhaust duct to the outside must be completely insulated.
It is recommended to insulate 5 ft. of supply air duct to the house (as shown).
In colder climate we recommend to insulate all exhaust and supply ducts.
Note:
-Use appropriate access door size for easy access and
routine maintenance of the unit.
*Re - circulation Efficiency
If distance “X” is 5 ft - 99.7%
“X” is 3 ft - 96.5%
When the outside temperature drops below -5°C, the HRV / ERV Supply Fan cycles ON / OFF depending on the outside
temperature. The exhaust fan always operates normally at all times regardless of the outside air temperature.
During defrost cycle the HRV unit may produce some condensation and the water should flow into a nearby drain.
Minimum 5 Feet

- HRV must be connected to drain.
- ERV does not required any drain. However,
we recommend to connect ERV to drain in
areas where extreme cold weather conditions are expected.
