General Information
The use of incorrect or makeshift fuses or the
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
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. | |
| Be careful when working behind the gas chromatograph (GC). During | |
WA R N I N G | ||
cycles, the GC emits hot exhaust which can cause burns. | ||
| ||
|
| |
| The insulation around the GC inlets, detectors, valve box, and the insulation cups is | |
WA R N I N G | ||
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. | |
