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 P-trap to prevent the unit from unpleasant odours from drain source. Tape or fasten base to avoid
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.

Typical Installations of Single Vents & Access door
(For vertical installation)
Use this drain for
horizontal installation
-Fresh air intake and supply duct must be totally insulated. Exhaust duct
must be 5 feet insulated. In colder climate, it is recommended to insulate
all exhaust and supply ducts.
Note:
-Use appropriate access door size for easy access and
routine maintenance of the unit. For more info visit

*Re - Circulation Efficiency
If distance “X” is 5ft - 99.7%
“X” is 3ft - 96.5%
When the outside temperature drops below -5°C, the Reversomatic HRV / ERV Supply Fan cycles ON / OFF depend 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.
Note:
- For Horizontal installation,
connect only 1 drain spout assembly on lid / door.
cut one ½’’ drain pipe and connect one end to the drain spout and the other
end to the drain line. Don't forget to create a P-trap as shown above.
- 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.
