Mounting
(CONT’D)
If a new motor mount is required
and the legs do not line up with
the original holes in the blower
housing, it is required to use a
bolt with either a lock washer
and nut or a locking nut through
the drilled hole(s). Self tapping
or sheet metal screws are not
sufficient for a long term installation
when a new hole is drilled through the thin wall of the blower housing.
When positioning the legs of the bellyband on the motor, make sure that
once the motor is mounted into the blower section, the wires exit the bottom
of the motor as installed in the air handler. This will insure that a proper drip
loop can be made with the signal and power lines.
The blower wheel should be centered in the blower
housing. The wheel should also not be against the
motor bearing housing. If this is not possible while
centering the wheel, the motor should be adjusted
in the belly band. If the blower wheel is dirty, it
should be cleaned.
The blower wheel hub locking bolt should be
secured to the flat portion of the motor shaft
after the wheel has been centered in the
blower housing.
Re-install the blower section in the HVAC system and proceed to the next
page to make the electrical connections.
- 4 -
As installed in the air
handler, the motor should
be positioned with the
connectors facing down
between the 4 and 8
o-clock position, with the
wiring harness formed
into a drip loop.
