NSTALLATION
Installation Notes:
•
The HRV must be balanced.
•
When balancing, all external exhaust systems should be
turned off (i.e., range hood, exhaust, bathroom vents).
•
All exhausting appliances should have their own make-up
air, as this is not an intended use for the HRV system.
•
The duct configuration may change depending on the
HRV model.
•
The airflow must be confirmed on site using the balancing
procedures found in this guide.
Spring-Loaded Backdraft Damper (recommended):
There is a location for an optional Backdraft Damper with the leaf hinge vertical. The damper is installed on
the “Stale Air to Outside” Collar.
Warning
•
Check local codes/authority having jurisdiction for acceptance.
•
Applications such as greenhouses, atriums, swimming pools, saunas, etc. have unique ventilation
requirements which should be addressed with an isolated ventilation system.
•
Weatherhood arrangement is for drawing purposes only. Check local codes/authority having
jurisdiction for acceptance.
•
Backdraft dampers are recommended for the stale air to outside air duct. This damper prevents
outdoor air from entering the HRV during the operation of the furnace/air handler while the HRV is
in standby, off, or recirculating.
