2.1.2 CENTRAL DRAW POINT (CONNECTION TO FORCED AIR SYSTEM)
VH0038
Stale air is drawn to the unit by the register located at the highest level of the
house. Filtered air is supplied to the retur
n (plenum) of the forced air unit.
For this type of installation, it is not essential that the forced air system blower
runs when the unit is in operation, but we recommend it.
See figure below.
NOTE: Home with multiple forced air systems should have 1 unit on each system.
