Literature E7EU High Airflow Blower Kit for Cooling Airflow
Product Information
The High Airflow Blower Kit is designed to increase the airflow of the factory installed E7 blower assembly. This kit enhances the cooling airflow of the unit.
Important Safety Information
Before servicing the equipment, it is crucial to read all
instructions provided in the manual. Pay attention to safety warnings and
special notes highlighted in the manual. Safety markings are used throughout
the manual to indicate the seriousness of potential hazards, which should not
be ignored. Failure to follow safety warnings and improper servicing could
result in personal injury, death, or property damage.
Dip Switch Settings and Airflow Data
The table below shows the dip switch settings and corresponding airflow data:
| Dip Switch Setting | External Static Pressure (in W.C.) | Airflow (CFM) |
|---|---|---|
| 1/4 | 0.1 | 1278 |
| 2/5 | 0.2 | 1359 |
| 3/7 | 0.3 | 1318 |
| 4/8 | 0.4 – 0.7 | Varying values |
| 0.8 | 0.8 | 1287 |
| 0.9 | 0.9 | 1250 |
| 1.0 | 1.0 | 1213 |
Notes
- Airflow values were measured with a 23kW heater kit and clean factory air filter installed, without a cooling coil cabinet attached.
- If using a 15kW or 17kW electric heat, add 50 CFM to the airflow values. If using a 10kW or 12kW electric heat, add 100 CFM to the airflow values.
- The pressure drop of a clean factory air filter is 0.08 inch W.C.

Product Usage Instructions
- Disconnect all power to the unit and remove the door. Remove the left access panel and disconnect the motor power and signal wires from the control board.
- Remove the 4 screws securing the blower housing and slide the assembly out of the unit.
- Install the new assembly in the same location, ensuring that the housing flanges slide underneath the blower deck tabs.
- Route the motor power and signal wires to the board and connect them according to the existing wiring diagram.
- Adjust the HEAT and COOL dip switch settings for the desired airflow.
- Reinstall the access panel and door, and restore power to the unit.
Important: Before starting the installation process, please read all instructions carefully and follow the safety warnings provided in the manual to ensure proper installation and avoid any potential hazards.
Required: Replace Electrical Data Labels
As part of the installation process, apply the electrical data labels provided in this High Airflow Blower Kit on top of the E7 electric furnace’s original rating labels. This step is necessary to ensure accurate electrical data information for the unit.
INSTALLATION INSTRUCTIONS
- HIGH AIRFLOW BLOWER KIT FOR COOLING AIRFLOW
- This kit is intended to provide increased airflow over the factory installed E7 blower assembly.
IMPORTANT SAFETY INFORMATION
INSTALLER: Please read all instructions before servicing this equipment. Pay attention to all safety warnings and any other special notes highlighted in the manual. Safety markings are used frequently throughout this manual to designate a degree or level of seriousness and should not be ignored. WARNING – Indicates a potentially hazardous situation that if not avoided, could result in personal injury or death.
- Disconnect all power to the unit and remove the door.
- Remove the left access panel, and disconnect the motor power and signal wires from the control board.
- Remove the 4 screws securing the blower housing and slide the assembly out of the unit.
- Install the new assembly in the same location while making sure the housing flanges slide underneath the blower deck tabs.
- Route the motor power and signal wires to the board and connect them according to the existing wiring diagram.
- Adjust the HEAT and COOL dipswitch settings for the desired airflow.

Table 2. E7 Furnace with High Airflow Blower Kit Electrical Data
REQUIRED: REPLACE ELECTRICAL DATA LABELS
This High Airflow Blower Kit contains electrical data labels that are to be
applied on top of the E7 electric furnace’s original rating labels as part of
installation of this kit.
Please follow these instructions:
- Locate the English and French electrical data labels included within the High Airflow Blower Kit. Also locate the English and French electrical data labels that are on the E7 electric furnace.
- Carefully apply the English and French electrical data labels from the High Airflow Blower Kit ON TOP of the original English and French electrical data labels on the E7 electric furnace, as shown in Figure 1.
- On the electrical data labels, CIRCLE the model of the E7 electric furnace into which the High Airflow Blower Kit was installed to correctly identify which row of electrical data is correct for that particular unit.
