4.3 Replacing a fuse
If there is no display, lights, or fan, and the PowerPac HC is plugged into a working
AC power outlet with the power switch in the "ON" position, the fuse may need to
be replaced.
1. Disconnect the power cord from the electrical outlet.
2. Insert a flat blade screwdriver into the notches of the power entry module's fuse
drawer to release it. See Figure 7.
3. Remove the fuse from the fuse drawer. Replace it with 8A, 250 V, 5x20 mm,
type T fuse (Bio-Rad part number 900-8933).
4. Re-insert the fuse drawer into its position. Press the fuse drawer gently until it
snaps into place.
The unit is now ready for use.
