Thread)3-1/4” Type “J” Thermocouple Ungrounded Junction E1 General Purpose Enclosure E2 Moisture-Resistant/Explosion-Resistant Enclosure GENERAL WARNING: This heater is not intended for use in hazardous atmospheres where flammable vapors, gases, liquids or other combustible atmospheres are present as defined in the National Electrical Code. Failure to comply can result in explosion or fire. The GCHIS-C is a gas circulation heater, designed especially for low flow rates and/or high temperature applications. The INCOLOY® sheathed cartridge style heating element is centered in a 304 stainless steel pipe body. High temperature insulation and jacket envelope the pipe body to reduce heat loss. Its screwplug type mounting provides easy removal when necessary. A Type K thermocouple is located inside the heating element sheath to provide overtemperature protection. Accurate process control can be achieved by means of the Type J thermocouple installed in the heater outlet. (Process and Hi-limit Controllers ordered separately.) WARNING: Users should install adequate back-up controls and safety devices with their electric heating equipment. When heating in closed vessels where the consequences of failure may be severe, controls and back-up controls must be used to prevent buildup of temperature and/or pressure. Although the safety of the installation is the responsibility of the user, Chromalox will be glad to make equipment recommendations. INSTALLATION WARNING: Hazard of Electric Shock. Disconnect all power before installing heater. 1. Before installing, check your GCHIS-C circulation heater for any damage that may have occurred during shipment. 2. Check to insure that the line voltage is the same as that stamped on the nameplate. 3. Vertical mounting (axis of chamber vertical as in figure above) is preferred. 4. To avoid excess temperatures at electrical wiring, mount heater with terminal enclosure at bottom, and use lower nozzle as inlet to the circulating steam, air or gas. 5. The GCHIS-C series of circulation heaters is provided with mounting lugs to support the heater chamber. Refer to figure for location of these mounting lugs. 6. Mount heaters to permit unrestrained expansion of chamber due to temperature. This can be accomplished by using slotted mounting assembly on either of the lugs. 7. Provide adequate space at terminal end to permit withdrawal of the heater from chamber should servicing be required. 8. DANGER: Hazard of Fire. Provide a minimum of 6” spacing from chamber and related piping to nearest combustible material. Do not operate heater near combustible fluids or in combustible vapor or gas laden atmosphere. 9. If two or more heaters are required to provide the needed heating capacity, arrange them for series gas or vapor flow. © 2010 Chromalox, Inc. INSTALLATION 10. DANGER: Possible Explosion. A pressure relief valve 11. In a forced circulation system, use pump on the inlet side. should be provided by customer at outlet of vessel. There should be no other valving between vessel and relief valve. WIRING WARNING: Hazard of Electrical Shock. Any installation involving electric heaters must be effectively grounded in accordance with the National Electrical Code to eliminate shock hazard. 1. All wiring should be done in accordance with local codes and the National Electrical Code by a qualified person. 2. Because of the high operating temperature expected, aluminum wiring should not be used. 3. When heater element wattages are not equal, heaters must not be connected electrically in series. 4. Electrical wiring to heater should be contained in rigid conduit or in sealed flexible hose when corrosive vapors or liquids are present. If high humidity is encountered, the conduit should slope down and away from the heater. 5. If flexible cord is employed, a watertight connector should be used for entry of the cord into the terminal box. Outdoor applications require liquid-tight conduit and connectors. 6. Wire separately ordered Hi-Limit and Process Controllers to thermocouples on heaters. OPERATION WARNING: Do not heat materials th...
