NOTE: Retain all screws and fasteners for installation of
the new blower assembly.
1. Before beginning the installation, make sure the unit is
not powered and any breakers/disconnects to the unit
are deactivated. Remove the furnace door.
2. Disconnect the thermostat wire connections and unhook
the 6-pin blower plug from the control panel socket.
3. Remove all screws attaching the blower assembly to
the furnace.
4. Slide out the complete blower assembly.
5. Replace the blower in step 4 with the ECM blower from
this kit. Slide into the same position as the removed
assembly, and then fasten with screws.
• For E3 series furnaces only: Install the grey
wire that is supplied with this kit. Determine your
appropriate model from Figures 1, 2, 3, or 4 (pages
2 & 3).
Firmly press the grey wire socket termination into
pin location #5 of the blower plug (in the control
panel) and the .25" push-on terminal into the open
contactor termination shown in Figures 1, 2, 3 & 4
(pages 2 & 3). The dashed line represents the field
installed grey wire.
• For E4 series furnaces only: Install the grey
wire that is supplied with this kit. Determine your
appropriate model from Figures 5, 6, 7, or 8 (pages
4 & 5).
a.) Temporarily remove the black wire from pin L1
on the control board.
b.) Firmly press the grey wire socket termination into
pin location #5 of the blower plug (in the control
panel) and the .25” push-on terminal into the L1
terminal.
b.) Replace the black wire onto the “piggy-back”
terminal of the grey wire at pin L1.
6. Plug the 6-pin plug from this kit into the control panel
socket.
7. Make the required thermostat wiring connections as
shown in Figure 9 (page 6).
8. Reinstall the furnace electrical panel and exterior door,
and then restore power to the unit.
The blower speed is preset at the factory for proper heating
and cooling operation. For optimum system performance
and comfort, it may be necessary to change the factory
set speed. Recommended settings are listed in Table 1
& Table 2. If heat and cool require tap 2, use the included
wire adapter and wire nut.
