Cleaning the
Fan Filter
The fan fi lter on the bottom of the instrument requires periodic cleaning. The
frequency of the cleaning depends on how dusty your particular lab is and
could range from once a month to once every six months.
1) Turn power to the instrument OFF and then remove the power cord and
cables from the back of the instrument.
2) Remove any plate or adapter from the instrument drawer. Turn the instru-
ment over so that it rests fl at on the bench.
3) Pop the black fan cover off and remove the fi lter.
4) Clean the fi lter by blowing clean, canned air through it or by rinsing it—
fi rst with water and then with alcohol—and allowing it to dry completely.
5) Place the clean, dry fi lter over the fan and replace the black cover.
6) Turn the instrument back over. Reconnect the power cord and cables to
the instrument.
Changing the
Fuses
Fuses burn out occasionally and must be replaced. If the instrument does not
seem to be getting power after switching it on (the LCD shows no display),
fi rst check to see whether the power cord is securely plugged in to a function-
ing power outlet and to the receptacle at the rear of the SpectraMax GEMINI
EM. If power failed while the SpectraMax GEMINI EM was already on, check
that the power cord is not loose or disconnected and that power to the power
outlet is functioning properly. If these checks fail to remedy the loss of power,
follow the steps listed below to replace the fuses. Spare fuses (two U.S. and
two metric) are shipped with the instrument. The U.S. and metric fuses are
identical except for physical size. They may be taped to the back of the Spec-
traMax GEMINI EM.
If you no longer have spare fuses, you may obtain new ones from Molecular
Devices (part numbers: 4601-0013 for U.S., 4601-0014 for metric) or from a
local hardware store. Make sure fuses are rated SLOWBLOW (U.S.: 4-amp
time-delay; metric: 4-amp, 5
×
20 mm, time-delay).
To change fuses, follow the steps below.
1) Switch power to the instrument off and then remove the power cord from
the outlet and from the SpectraMax GEMINI EM power cord receptacle.
2) Remove the printer cable and computer cable (if connected) from the back
of the SpectraMax GEMINI EM.
3) Turn the instrument around for easy access to the rear panel.
4) On the left-hand side of the rear panel (viewed from the back) is the
power switch, fuse box, and power cord receptacle. As shown in the fi g-
ures below, press to the left of the black plastic cover of the fuse box to
release it. Pull the fuse box cover away from the instrument. The fuse box
will begin to slide forward.
