CAUTION:
Before installing a media filter into the HVAC system, the Qualified Agency must consider the additional pressure drop being added to the HVAC system.
1.The filter must be installed on the return side of the HVAC system, between the return air duct and the intake of the system blower. NEVER install on the supply side of the HVAC system.
2.The filter access panel MUST be installed where there is at least
3.Some installations may require a duct transition. Transitions may be needed to reduce pressure drop and maintain appliance efficiency. The appliance must operate within the manufacturer’s recommended temperature and pressure drop requirements.
4.Check the flow capacity and pressure drop
(Figure 6) to determine the filter is properly sized. | Figure 6 |
INSTALLATION:
WARNING: Always shut off the electrical power supply before working on the appliance.
1.Refer to the typical mounting positions (Figures 1 to 5) for proper placement of the filter cabinet.
2.Remove the metal filter cabinet from the carton and plastic bag.
3.Remove the access panel door and pull the media filter (in plastic bag) out of the cabinet. DO NOT install the media filter with the plastic bag around it.
4.Position cabinet so access panel is available for easy media filter replacement The access panel MUST be accessible to remove and replace the media filter. (Note: Minimum of
5.Position the filter cabinet onto return air side of the appliance (Figures 1 to 5). Duct transitions may be required to properly mount the filter cabinet.
6.When the filter cabinet is mounted directly to the appliance or existing duct, mark the inside opening of the filter cabinet and all 12 mounting screw locations.
7.Drill the marked mounting holes with a 1/8 inch diameter drill bit. Remove the marked filter opening with metal cutting shears or equivalent.
8.Attach filter cabinet to the appliance or duct work using #8 X 1/2 inch long sheet metal screws or pop rivets. Seal the housing connections with aluminum duct tape or equivalent.
9.Remove media filter from the plastic bag and discard the plastic bag. TIP: Write the installation date on filter next to directional arrow for future filter replacement reference. The media filter MUST be installed WITHOUT the plastic bag.
10.Install media filter into the filter cabinet.
11.Install the filter cabinet access panel.
12.Place appliance back into service. Appliance must operate within the appliance manufacturer’s recommended temperature and pressure drop requirements.
