INSTALLATION EXAMPLES
Example diagram only-duct configuration may change depending on model
DIRECT CONNECTION of the SUPPLY AIR STREAM to the FURNACE COLD AIR RETURN
(Stale air drawn from key areas of home)
Partially Dedicated System
Stale air drawn from key areas of
home (bathroom, kitchen, laundry)
Fresh air supplied to main living areas
via the forced air system.
ERV must be balanced
CAUTION
In very humid climates, it may be preferable to have a ded-
icated ducting system to the house for the ERV instead of
connecting the ERV to the central air-conditioner. Since
the central air-conditioner fan must be running continu-
ously to allow the fresh air from the ERV to be properly
distributed throughout the house, it may pick up humidity
from the cooling coil when it is not operating and re-dis-
tribute it to the house, causing excess humidity. This sit-
uation may be particularly aggravated if the air-condition-
er is over-sized.
* Ducts connection may
vary depending on model
Outdoors
NOTES:
1.Furnace blower may be required to operate when ERV is on to provide good air distribution. (SEE CAUTION ABOVE)
2.Weatherhood arrangement is for drawing purposes only. 6' (2m) minimum separation recommended.
18" (460mm) above grade minimum.
3.Due to the differences in pressure between the ERV and the equipment it is being connected to, the ERV's airflow must be confirmed on
site, using the balancing procedure found in the installation manual.
