Ordinary location heaters (designated E1) are 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 personal injury or property damage. This design has the versatility of field adjustments of voltage kW through various wiring combinations. The NWHSRG model is a general purpose water circulation heater intended for indoor use. E2 designs have a Moisture Resistant/Explosion Resistant enclosure. Designs are up to 40kW -DO NOT USE THE NWHSRG MODEL FOR OIL. The NWHOSR model is a general-purpose regular and fuel oil solution circulation heater intended for use indoors. E2 designs have a Moisture Resistant/Explosion Resistant enclosure. Designs are up to 10kW - DO NOT USE THE NWHOSR MODEL FOR WATER. Ensure the wiring guide for oil is used for the correct wiring diagram. Both the NWHSRG and NWHOSR use six INCOLOY® sheath elements welded to a steel 2.5” screw plug. The vessel is cast iron and is surrounded by 1.5” insulation and a sheet metal jacket. For water applications, the vessel has a galvanized coating. A J-type thermocouple in a thermowell is standard. These versaTHERMTM heaters are designed for 150 psig max. at 35°F min. to 300°F max. IMPORTANT: 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. ELECTRIC SHOCK HAZARD. Disconnect all power before installing or servicing heater. Failure to do so could result in personal injury or property damage. Heater must be installed or serviced by a qualified person in accordance with the National Electrical Code. NFPA 70. The system designer is responsible for the safetyof this equipment and should install adequateback-up controls and safety devices with theirelectric heating equipment. Where the consequences of failure could result in personal injury orproperty damage, back-up controls are essential. If foreign material is to be carried by the liquid flow, install suitable filters in the inlet pipe to the heater. Ensure the temperature/pressure is controlled below the vapor point of the liquid at all times and is within the temperature/pressure ratings for this heater. Heating elements must be completely immersed in liquid when energized. © 2010 Chromalox, Inc. INSTALLATION ELECTRIC SHOCK HAZARD. Disconnect all power before installing heater. Failure to do so could result in personal injury or property damage. Heater must be installed by a qualified person in accordance with the National Electrical Code. NFPA 70. 1. Vertical Mounting (Preferred) — When the heater is vertically mounted, the electrical enclosure will be at the top of the heater. The inlet pipe will be located on the side near the bottom of the heater and the outlet pipe at the top. Figure A — Vertical Mounting Correct Incorrect The axis of the chamber will be in a vertical position as in Figure A. 2. Horizontal Mounting (Optional) — When mounting heater horizontally, inlet and outlet pipes must be up. In any other position, heater cannot be purged of air, and elements may be seriously damaged. (See Figure B.) Note: Heater cannot be completely drained in the horizontal position. When mounting the heater, allow adequate spacing for draining the heater. Figure B — Horizontal Mounting Correct Incorrect 3.Whether vertical or horizontal, the heater should be rigidly mounted so that vibration is at a minimum since excessive vibration will result in erratic thermostat operation (if thermo- stat is used instead of thermocouple). The NWHOSR/NWH- SRG is provided with mounting lugs to support the heating chamber. (See drawing on front page.) FIRE HAZARD. An integral thermostat,...
