Instrument Installation Installation Site The Discover/Explorer SP System may be installed in a laboratory fume hood or on a laboratory bench with proper ventilation. Choose a location that Provides at least 8 in. (20 cm) of open space on each side and 6 in. (15 cm) of open space in the rear of the instrument for ventilation. The space should be at least 22 in. (56 cm) wide by 25 in. (64 cm) deep with a height clearance of at least 35 in. (89 cm) Is free from vibration of large equipment and/or excessive walk-through traffic Provides a temperature range of 41 F (5 C) to 104 F (40 C) and a humidity range of 10-85% relative humidity Provides adequate space for sample handling and computer placement, if applicable Permits the system to be connected to a dedicated, grounded 120 VAC outlet. The Discover SP System should be operated on a stabilized, constant voltage AC power supply. To operate properly, the voltage must be within ±10 % of the specified level. Tools Required: Razor blade or box cutter. Unpack the System 1. Open the Discover SP and Explorer shipping cartons. 2. Remove the accessory kits & packing materials. 3. Carefully remove the Discover SP and Explorer modules from their shipping cartons. 4. Inspect the instrument for shipping damage such as cracks, dents, or warping. If the instrument has been damaged in shipping, contact the freight carrier to report the damage and to file a damage report. Contact CEM to report damage at 800-726-5551. 5. Retain all packing materials for return shipment to the manufacturer if the need should arise. WARNING If damage to the instrument is noted upon receipt, do not attempt to operate the instrument. Never modify the attenuator access port or insert metallic objects, such as wire, into the port. Serious microwave leakage and/or electrical shock may result. The access port of the Discover is electrically grounded to the microwave cavity and is designed to prevent leakage of microwave energy. Cardiac pacemakers require magnets to control operation during checkout. Because the Discover SP System is equipped with a variable-speed, electromagnetic sample stirrer, some danger exists if a pacemaker is positioned in close proximity to the instrument cavity. If the instrument is suspected of interfering with the operation of a pacemaker, the instrument should be turned off or the pacemaker wearer should move away from the instrument.
