Repairing
Replacing the RF Connector
ONLY the Model 8890 has a special Bird “QC” connector which allows easy
changing of the RF connector. This does not disturb the coolant seal or affect the
electrical continuity of the load. To change the connector, proceed as follows:
1. Remove the four screws at the corners of the RF connector.
2. Pull the connector straight out.
3. Push the new connector in. Make sure that the center pin on the connector
is properly seated in the mating socket on the load.
4. Replace the screws.
Note:
If not using the LC connector normally supplied, the fre-
quency and power must be limited to the capabilities of the connector.
Replacing the Fuse
Note:
The fuse is located in the AC module on the back of the blower.
1. Correct the fuse burnout cause.
Note:
Common causes include stuck or blocked fans or a short cir-
cuit in the motor or blower wiring.
2. Press the locking tab on the fuse drawer and remove the drawer.
3. Replace the fuse.
Note:
See “Specifications” on page 22 for fuse type and current rating.
4. Push the drawer into the AC module until it locks into place.
Note:
If the fans still do not run or if the fuse burns out again,
return the blower assembly to the factory.
Replacing the Indicator Light
1. Remove the four 8-32 pan head screws from the front and back of the base frame.
2. Pull the fan guard straight off the bottom.
3. Remove the quick disconnects on the light and unscrew the retaining sleeve.
4. Remove the light unit.
5. Remove the lens while pressing both locking tabs.
6. Press the housing’s center slot with a small screwdriver to release the lamp.
7. Push the new lamp into the housing until it snaps into place.
8. Replace the lens, then put the light unit back in place.
9. Replace the fan guard and screw in the 8-32 pan head screws.
