Troubleshooting and Maintenance Guide

General Maintenance
To Replace the Primary Fuses
Materials needed
•
Fuse, T8 A, 250 V (2110-0969) – 2 required
•
Screwdriver, flat-blade (8730-0002)
The most likely cause of failure of the primary fuses is a
problem with the foreline pump. If the primary fuses in your
MSD fail, check the foreline pump.
Procedure
1
Vent the MSD and unplug the power cord from the electrical
outlet.
If one of the primary fuses has failed, the instrument will
already be off, but for safety you should switch off the
instrument and unplug the power cord. It is not necessary to
allow air into the analyzer chamber.
2
Turn one of the fuse holders (
) counterclockwise
until it pops out. The fuse holders are spring loaded.
3
Remove the old fuse from the fuse holder.
4
Install a new fuse in the fuse holder.
5
Reinstall the fuse holder.
WA R N I N G
Never replace the primary fuses while the instrument is
connected to a power source.

If you are using hydrogen as a GC carrier gas, a power failure may
allow it to accumulate in the analyzer chamber. In that case,
further precautions are required. See
