Replacing fuses or resetting circuit breakers
Perform this procedure as needed for maintenance.
Tools needed:
• Long flat-blade screwdriver
• 8 Amp fuse
• 12.5 Amp fuse
Never replace a fuse while the instrument is plugged into the power outlet. You
run the risk of an electric shock.
If the instrument is plugged in and turned on when you change a fuse, you will
damage the instrument.
To replace fuses or reset circuit breakers,
1 Unplug the instrument power cord or cords from the power outlet.
2 If your LC/MS instrument includes circuit breakers and you need to reset
them, press in the circuit breaker buttons.
3 Using a flat-blade screw driver, remove the fuse holder of the blown fuse.
4 Replace with the appropriate fuse.
5 Reinstall the fuse holder.
6 Plug in the instrument.
