GENERAL sition. The slope of the transformation piece on the upstream side of the equipment is limited to 30° as indicated in Figure 3. FIRE/EXPLOSION HAZARD. This heater is not On the leaving side, the slope should not be more than 45°. intended for use in hazardous atmospheres where 6. Use moisture proof terminal cover in atmospheres bearing cor- flammable vapors, gases, liquids or other com- rosive fumes or excessive moisture. bustible atmospheres are present as defined in the 7. Use explosio

INSTALLATION (cont’d.) 6. In high ambient temperature operations, least corrosive action and least oxidation to the terminals will occur if the heaters are HAZARD OF FIRE. Since these heaters are capable of mounted with the terminals in the coolest possible ambient, developing high temperatures, extreme care should usually on the bottom or side of the duct. be taken to: A. Minimum duct size is “A” or “L” dimension +3/8” and “B” A. Avoid installing heaters in an atmosphere containing com- dimens

OPERATION Do not operate heater at voltages in excess of that stamped on the heater since excess voltage will shorten heater life. MAINTENANCE 1. Periodically clean terminals and terminal covers of dust and corro- sion to maintain good electrical connections and to permit rapid heat dissipation. Use airblast, and be careful to avoid damage to ELECTRIC SHOCK HAZARD. Disconnect all power mica insulation. before installing or servicing heater. Failure to do 2. Check for loose terminal connections.
