7. Slide ECM blower assembly into furnace and tighten
screws to secure blower assembly to the blower shelf.
8. Reinstall furnace control box on bottom side of
blower shelf.
9. Connect electrical leads from furnace control pre
viously used as blower speed selector taps to
numbered connector which is panel mounted on the
left side of the interface control box. Black lead to
position 1, red lead to position 2, white lead to posi
tion C.
10. Double-check to make sure main power disconnect
is off.
In steps 11 through 14, the 115-v power leads to ECM
blower icit connects in parallel with furnace 115-v power
supply. To do this:
11. Remove cover of auxiliary junction box.
12. Remove strain relief securing the power leads in place
on the auxiliary J-box.
13. Route power leads from ECM blower kit through
opening in back of auxiliary junction box. Dis
connect black lead from furnace control at door
switch, and connect black lead with 3/16-in. piggy
back quick-connect from ECM blower kit in its place.
Then reconnect black lead from furnace control to
3/16-in. male quick-connect provided on piggyback
connector. Remove wire connecting white lead of
furnace control to line voltage common line. Connect
white wire from ECM blower kit and reinstall wire
nut.
Make sure all power leads are secured in place using
the strain relief provided with this kit.
Reinstall cover to auxiliary junction box.
Disconnect all existing thermostat leads from the
furnace control board if applicable.
Connect W, R, and C from terminal block TB3
labeled, HEAT, on interface circuit board located on
front of blower housing to their respective thermostat
connections on furnace control board, labeled (W,
R, C) using field-supplied thermostat wire cut 6 in.
in length and stripped 1 /4 in. on each end. See Fig. 3.
Install thermostat following instructions included
with outdoor section. For single zone applications,
route 6-conductor thermostat wire into furnace
through one of the knock-outs in the cabinet. Multi
zone applications require only 3-conductor wire.
Slide electrical noise suppressor provided, over
thermostat wire before making electrical connections
(see Fig. 3) at blower assembly.
NOTE; For electrical interference and noise, refer to
38EV,QV outdoor section Installation, Start-Up and
Service Instructions.
