H. BLOWER REPLACEMENT
CAUTION– Failure to wear anti-static equipment during service may damage
this device.
1. See instructions above to remove the cover, control PC board and blower.
2. Insert the blower mount foam on the blower base so that the holes in the foam align
with the protrusions on the blower and the blower wire harness is through the center
hole in the foam. (Fig. 6)
3. Turn the blower over so that the motor is facing down. Guide the wire harness
through the hole in the bottom of the blower cavity portion of the chassis.
4. Lower the blower with its outlet port pointing at the silicone isolator. Position
the blower's outlet port into the top edge of the silicone isolator then tilt the
outlet port into the isolator opening without folding the isolator. Push the outlet
port into the isolator until the port is evenly inserted into the isolator. See isola-
tor image in Blower Removal instructions above.
5. Insert the blower wrap foam so that the single-notched end is beside the blower
outlet port. Wrap the remaining foam strip clockwise around the blower so
that the notched foam corresponds to the latches on the blower body. Wrap the
double-notched end around the blower and over the outlet port. The top edge
of the foam should be almost fl ush with the blower. (Fig. 7)
6. Insert the top blower foam so that it conforms to the edges of the blower cavity
portion of the chassis.
7. T urn the chassis over so that the blower is facing down. Gently pull any slack from the
wire harness. Insert the silicone grommet into the hole in the chassis so that the slit
in the grommet is toward the power supply board location, all the wires are in the
center hole of the grommet and the grommet fl ange is fully sealed. Route the wire
harness along the top of the chassis and down the front of the blower cavity portion of
the chassis. (Fig. 8)
