(Stale air drawn from key areas of home)
Partially Dedicated System

Fresh air supplied to main living areas via the forced air system.
NOTES:
1.Furnace blower may be required to operate when HRV/ERV is on to provide good air distribution.
2.Weatherhood arrangement is for drawing purposes only.
3.Due to the differences in pressure between the HRV/ERV and the equipment it is being connected to, the HRV/ERV's airflow should be confirmed on site, using the balancing procedure
found in the installation manual. If a release is required due to the furnace pulling too much air from the HRV/ERV, special care and attention is needed to its design.
NOTE* PHRV96 should be
mounted with its duct connec-
tions on top or similar.
