A list of the necessary tools and suppliesappears at the beginning of the “Installation” chapter. Most suppliesare available from Hewlett-Packard. See the HP Analytical Direct Analytical Columns and Suppliescatalog for descriptionsand orderinginformation. You can obtain a copy of the catalog from your local sales office. Temperature and humidity ranges Operating the GC within the recommendedranges insuresoptimum instrument performanceand lifetime. Recommended temperature Temperature range range E E 20to27 C 5to40 C Recommended humidity range Humidity range E 50to60% Upto31 C,5to80% E At40 C,5to50% Recommended altituderange Upto2000m After exposing the GC to extremes of temperature or humidity, allow 15 minutes for it to return to the recommendedranges. 3 SitePreparation Ventilation requirements The GC is cooled by convection: air enters vents in the side panels and underneath the instrument. Warmed air exits through slots in the top, rear, and side panels. Do not obstruct air flow around the instrument. For propercooling and general safety, always operate the instrument Caution with cover panels properlyinstalled. Venting oven exhaust Hot air (up to 450EC) from the oven exits through a vent in the rear. Allow at least 20 cm (10 in.) clearance behind the instrument to dissipatethis air. Do not place temperature-sensitiveitems (for example, gas cylinders, chemicals, or regulators) in the path of the heated exhaust. Be careful WARNING when working behind the instrument during cool-downcycles to avoid burns from the hot exhaust. If space is limited, the Oven Exhaust Deflector (HP part no. 19247-60510) may improve oven cooling. It diverts exhaust air up and away from the instrument. You can connect it to a 10.2-cm (4-in.) exhaust-duct system, route the exhaust to a fume hood, or vent the exhaust outside the building with 10.2-cm diameter (4-inch diameter) furnace duct. Venting toxic or noxious gases During normal operation of the GC with many detectors and inlets, some of the carriergas and sample vents outside the instrument. If any sample components are toxic or noxious, or if hydrogen is used as the carriergas, the exhaust must be vented to a fume hood. Place the GC in the hood or attach a large diameter venting tube to the outlet for proper ventilation. To further prevent contamination from noxious gases, you can attach a chemical trap to the splitvent. 4 SitePreparation Benchtop space requirements The GC with electronicpneumatics control (EPC) is 59 cm (23 in.) wide. The nonEPC model is 68 cm (26.7 in.) wide. Both are 50 cm (21 in.) high and 50 cm (21 in.) deep. The area above the GC should be clear, with no shelves or overhanging obstructions that limit access to the top of the instrument and interfere with cooling. You may need additional space for other instruments used with your GC. Figure 1 shows some common system configurations. Table 1 presents the dimensions,voltage requirements, heat production, and weight of the GC and other Hewlett-Packard instruments often used with it. Use this table to insure that you have adequate space and power for the entire system. Allow at least 10.2 cm (4 in.) space between instruments for ventilation. 5
