Warning All these parts are shielded by covers. With the covers in place, it should be
difficult to accidentally make contact with dangerous voltages. Unless
specifically instructed to, never remove a cover unless the detector, inlet, or
oven are turned off, or the power cord is unplugged.
Warning If the power cord insulation is frayed or worn, the cord must be replaced.
Contact your Agilent service representative.
Electrostatic discharge is a threat to GC electronics
The printed circuit (PC) boards in the GC 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.
Many parts are dangerously hot
Many parts of the GC operate at temperatures high enough to cause serious
burns. These parts include but are not limited to:
•
•
•
•
•
You should always cool these areas of the GC 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.
Warning Be careful when working behind the instrument. During cool-down cycles, the
GC emits hot exhaust which can cause burns.
