General Information
The use of incorrect or makeshift fuses or the short-circuiting of fuse holders
creates a shock hazard for the operator and can damage the instrument.
Replace fuses only with fuses of identical current rating and type.
Excessive fluctuations in the line voltage can create a shock hazard and can
damage the instrument. Make sure the supply voltage does not fluctuate more
than +5% or -10% from the rated voltage. This equipment must be installed in a
Category II environment as defined in IEC 664.
Electrostatic discharge is a threat to MSD electronics
The printed circuit (PC) boards in the MSD can be damaged by electrostatic
discharge. Do not touch any of the boards unless it is absolutely necessary. If
you must handle them, wear a grounded wrist strap and take other antistatic
precautions. Wear a grounded wrist strap any time you must remove the MSD
covers.
Many parts are dangerously hot
Many parts of the MSD operate at temperatures high enough to cause serious
burns.
You should always cool heated areas of the MSD to room temperature before
working on them. They will cool faster if you first set the temperature of the
heated zone to room temperature. Turn the zone off after it has reached the
setpoint. If you must perform maintenance on hot parts, use a wrench and
wear gloves. Whenever possible, cool the part of the instrument that you will
be maintaining before you begin working on it.
WA R N I N G
Be careful when working behind the gas chromatograph (GC). During cool-down
cycles, the GC emits hot exhaust which can cause burns.
WA R N I N G
The insulation around the GC inlets, detectors, valve box, and the insulation cups is
made of refractory ceramic fibers. To avoid inhaling fiber particles, we recommend
the following safety procedures: ventilate your work area; wear long sleeves,
gloves, safety glasses, and a disposable dust/mist respirator; dispose of insulation
in a sealed plastic bag; wash your hands with mild soap and cold water after
handling the insulation.
