2. TYPICAL INSTALLATIONS (CONT’D)
2.1HEPA 1000 AND HF 1.0 UNIT INSTALLATIONS (CONT’D)
2.1.2CENTRAL DRAW POINT (CONNECTION TO FORCED AIR SYSTEM)
Stale air is drawn to the unit by the register located at the highest level of the house. Filtered air is supplied to the return (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.

Do not connect the unit (HEPA 1000 or HF 1.0) on any forced air system supply duct. Connect it only to the air return duct. Do not install duct or duct connector directly above the forced air unit or not less than 2’ (0.61 m) of the plenum connection to the forced air unit, as measured along the length of the duct.
