Replacing a Fuse
Instrument power is supplied by two 2.0 amp, 250 V, TL, 5 mm OD
×
20 mm length fuses.
The fuses are housed in the fuse compartment on the lower right corner as you are facing the
back panel of the pump (next to the power cord). If an electrical component in your pump
stops working, first check for a blown fuse.

To replace a fuse
1. Turn off the pump and disconnect its power cord.
2. Use a flat blade to press down on the plastic tab at the top edge of the fuse compartment
and pull out the fuse holder.
3. Inspect each fuse for a burned or broken wire (which indicates a blown fuse).
4. Pull the blown fuse out of the holder and discard it. Place the new fuse (2.0 amp, 250 V,
TL, 5
×
20 mm) into the holder with the metal end visible.
5. Snap the fuse holder back into place.
6. Reconnect the power cord and turn on the pump.
If the replacement fuse fails in a short time, you have a serious electrical problem. Leave the
blown fuse in place and contact your Thermo Fisher Scientific service representative.
