Anleitung Zusammenfassung
WARNING: It is the responsibility of the purchaser of the heater to make the ultimate choice of sheath material based upon his knowledge of the chemical composition of the corrosive solution, character of the materials entering the solution, and controls which he maintains on the process. Chromalox cannot warrant any electric immersion heater against failure by sheath corrosion if such failure is the result of operating conditions beyond our control. 1. Heater Construction Characteristics A. High quality Nichrome resistance wire held in place by compacted Magnesium Oxide in various sheath materials. B. Medium watt densities. C. Steel terminal box painted with heat and acid-resistant paint. D. Lightweight yet heavy duty. E. Riser type construction puts the heat at the bottom inducing natural “stirring action” and evenly distributed temperatures. CAUTION: Users should install adequate controls and safety devices with their electric heating equipment. Where the consequences of failure may be severe, backup controls are essential. Although the safety of the installation is the responsibility of the user, Chromalox will be glad to make equipment recommendations. INSTALLATION 1. Before installing the type TBL heater, inspect it for possible damage which may have occurred during shipment. Also, check to insure that the line voltage is the same as that stamped on the nameplate. 2. IMPORTANT: Mount heater in the tank so that the liquid level will always be above the effective heated portion of the heater. If the heater is not properly submerged, it will overheat and damage the heating elements and create a possible fire hazard due to excessive sheath temperatures. 3. Where work will pass over or near equipment, additional protection, such as a metal guard, may be needed. 4. In an electroplating operation the heaters are not, under any circumstance, to be placed between the electrodes and the work. 5. When melting solids by direct immersion, a surface vent should be provided to allow gases to escape. Operate the heater on half voltage until melted material completely covers the heater area. 6. A drip loop is recommended to minimize passage of moisture along wiring into terminal box and connections. 7. DANGER: Hazard of Fire. Since these heaters are capable of developing high temperatures, extreme care should be taken to: A. Use Explosion-resistant terminal housings in hazardous locations. See Chromalox catalog for selection of explosion-resistant terminal enclosures for hazardous locations. B. Avoid contact between heater and combustible material. C. Keep combustible materials far enough away to be free of the effects of high temperatures. © 2010 Chromalox, Inc. WIRING CAUTION: Hazard of Electric Shock. Any installation involving electric heaters must be effectively grounded in accordance with National Electrical Codes to eliminate shock hazard. 1. Electrical wiring to heater must be installed in accordance with the National Electrical Code and local electric codes. 2. When element wattages are not equal, heaters must not be connected in series. 3. Electrical wiring to heater should be contained in Rigid Conduit or in sealed Flexible...
