In extreme humidity conditions, the use of additional dehumidification may be desirable. Quickly remove all excess moisture and keep areas clean. - 10 2. TYPICAL INSTALLATIONS (CONT’D) 2.2 INSTALLATION FOR HEPA 4000 ONLY (CONT’D) 2.2.2 HEPA 4000 ATTIC INSTALLATION All 3 types of installation can be used in the attic (Stand Alone, Central Draw Point or Return-Return). The example shown below is a Return-Return installation (connection to a forced air system). CAUTION Due to the potential temperature difference between the attic and the rest of the house, all unit ducts must be insulated. CAUTION The attic temperature must always be above 0°C (32°F). A portion of stale air is exhausted to the outside and the rest is drawn to the unit. Outside fresh air is blended with interior air and then filtered. This filtered air is supplied to the return (plenum) of the forced air unit. To avoid the cross-contamination and achieve highest efficiencies, the forced air system blower must always be ON (or the unit efficiency will be affected). See figure below. NOTE: Home with multiple forced air systems should have 1 unit on each system. VH0051 Do not connect the HEPA 4000 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 9’10’’ (3 m) of the plenum connection to the forced air unit, as measured along the length of the duct. CAUTION - 11 2. TYPICAL INSTALLATIONS (CONT’D) 2.3 HEPA 2000, HF 2.0, HEPA 3000, HF 3.0 AND HEPA 4000 UNIT INSTALLATIONS 2.3.1 STAND ALONE (Primarily for homes with radiant hot water or electric baseboard heating.) A portion of stale air (coming from the register located at the highest level of the house) is exhausted to the outside and the rest is drawn to the unit. Outside fresh air is blended with interior air and then filtered. Fresh filtered air is supplied by the register located in the lowest livable level. See figure below. VH0039 - 12 2. TYPICAL INSTALLATIONS (CONT’D) 2.3 HEPA 2000, HF 2.0, HEPA 3000, HF 3.0 AND HEPA 4000 UNIT INSTALLATIONS (CONT’D) 2.3.2 CENTRAL DRAW POINT (CONNECTION TO A FORCED AIR SYSTEM) A portion of stale air (coming from the register located in the highest level of the house) is exhausted to the outside and the rest is drawn to the unit. Outside fresh air is blended with interior air and then filtered. This 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 2000, HF2.0, HEPA 3000, HF 3.0 or HEPA 4000) 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 9’10’’ (3 m) of the plenum connection to the forced air unit, as measured along the length of the duct. CAUTION - 13 2. TYPICAL INSTALLATIONS (CONT’D) 2.3 HEPA 2000, HF 2.0, HEPA 3000, HF 3.0 AND HEPA 4000 UNIT INSTALLATIONS (CONT’D) 2.3.3 RETURN-TO-RETURN INSTALLATION (CONNECTION TO A FORCED AIR SYSTEM) A portion of stale air is exhausted to the outside and the rest is drawn to the unit. Outside fresh air is blended with interior air and then filtered. This filtered air is supplied to the return (plenum) of the forced air unit. To avoid the cross-contamination and achieve highest efficiencies, the forced air system blower must always be ON (or the unit efficiency will be affected). The HEPA 2000 and HF 2.0 units need to be ON all the time, since they don’t have motorized dampers. If these units are OFF, then the forced air unit will draw outdoor air inside. NOTE: Home with multiple forced air systems should have 1 unit on each system. VH0043 Do not connect the unit (HEPA 2000, HF2.0, HEPA 3000, HF 3.0 or HEPA 4000) 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 9’10’’ (3 m) of the plenum connection to the forced air unit, as measured along the length of the duct.
