Replacing a Fuse
A blown fuse may indicate the existence of another
problem in the instrument. If the replacement fuses
blow, don’t try others. Contact your local
representative or Gilson. See Before calling us on
page 5-8.
To change a fuse, follow these steps.
1 Disconnect the power cord from the power
outlet and from the rear panel receptacle.
2 Locate the fuse drawer on the rear panel. See
page 2-16 if necessary.
3 Insert a small screwdriver into the notch next to
the fuse drawer.
4 Twist the screwdriver to open and remove the
fuse drawer. The fuse drawer contains one
5.0A “T” Slo-Blo fuse (5 x 20 mm size) for a
100/120 voltage selection. It contains two 5.0A
fuses for a 220/240 voltage selection.
5 Remove the old fuse(s) and insert the new
fuse(s).
6 Insert the fuse drawer into its receptacle in the
liquid handler.
