Installation Methods - Fully Dedicated
The fully dedicated installation draws stale air from specific points in the house and delivers fresh air to specific locations
of the house. This system is not connected to an air handler/furnace (see the following figures).
Figure 22. Fully Dedicated System
Stale air ducts should be installed in areas of the home where the poorest indoor air quality exists (bathrooms and kitch-
en). Each location with a stale air duct should have a timer to initiate high−speed ventilation. Refer to “H/C 20/40/60 Minute
Timer (Y2169) (Optional) and H/C Ventilation Wireless Timer (Y8251)” on page 21.
The air handler/furnace blower should be running when the ERV/HRV is operating to evenly distribute the fresh air
throughout the house. Refer to “Interlocking ERV/HRV Blower to Air Handler/Furnace Blower” on page 33.
Key Points
• The ERV/HRV must be balanced.
•
The duct configuration may change depending on the ERV/HRV model. See specifications for your unit.
• Check local codes and authority having jurisdiction for acceptance.
Installation Notes
See unit specifications for exact port locations.
Unit is normally balanced on HIGH speed with the furnace blower ON.
The airflow must be confirmed on site using the balancing in this instruction
.
