Installing the Blower (CE-140, CE-180, and CE-250):
(1) Refer to Figure 2.
(2) Remove the three shipping brackets (CE 250 blower assembly only).
(3) Place the blower inside the mounting angles on the back of the furnace with the blower
bubble turned up.
(4) Use the included #10 self-drilling screws to secure the blower housing to the mounting
angle brackets on the back of the furnace cabinet.
(5) Connect the flexible conduit from the blower motor to the rear electrical box.
(6) Connect the wire leads according to the electrical schematic label in the rear junction box.
(7) Fasten the blower guards with the remaining #10 self-drilling screws to each side of the
blower.
WARNING:
Blower guards must be in place to prevent personal injury. NEVER
operate the furnace without all guards in place!
NOTICE:
The blower motor is designed to operate with the guards in place. Without the
guards in place the blower will move more air which may overload and damage the blower
motor.
NOTICE:
The blower must be mounted with the “bubble” turned up. If the blower is not
mounted in this position, the internal air flow through the furnace cabinet will change which
may cause the unit to cycle on high limit.
