HomeMy WebLinkAbout[02-30]Electric Heaters A Pentair Company Item Number: 30 Application Designed to protect sensitive mechanical, electrical, and electronic equipment from the harmful effects of condensation, corrosion, and low temperatures. Thermostatically controlled fan - driven heater units maintain a stable temperature within enclosures so critical components can perform more reliably over a longer period of time. Construction • Attractive and durable housing is anodized aluminum • Thermostat, standard on all units, is adjustable from 0 °F to 100 °F ( -18 °C to 38 °C) • Fan draws cool air from the bottom of the enclosure and passes this air across the thermostat and heating elements before being released into enclosure cavity • Heated air is discharged through the top of the heater unit • Four 10 -32 x self - tapping screws are included with each heater • Ball bearing fan runs continuously for even temperature distribution • Terminal block has three 6 -32 screw terminals with barriers labeled for power and ground connections Finish Anodized aluminum. Industry Standards UL Component Recognized CSA Listed CE Standard Sizes Electric Heaters Installation Hoffman electric heaters should be centered as low as possible on an interior enclosure panel. This permits the unit to heat the cool air located at the bottom of the enclosure. For maximum efficiency, the heater should be mounted in a vertical position with the terminal block to the bottom and the air outlet openings at the top. However, the unit will also effectively distribute heat if turned 90 degrees with the terminal block out the bottom and the air outlet at the side.Although enclosure panels are preferable, heaters may be installed on any flat sheet metal surface. Do not install heaters on wood panels. Heat sensitive components should not be placed near the heater discharge area since this air can be quite warm.The clearance range defines the space that must be kept free of these components for proper and safe operation of the heater.

FailurE to follow these instructions could damage the product or cause a hazardous condition. 2. Check the ratings on the heater label to assure the product is suitable for your application. To avoid electric shock and equipment damage, disconnect any power supplies to the enclosure before installing the electric heater. GENERAL SAFETY INFORMATION 1. Protect the lead wires from coming in contact with sharp objects, hot surfaces, and/or chemicals. 2. If continuous operation of the heater is essential to the safe functioning of any other equipment, adequate warning devices must be installed to assure safe operation at all times. F .. AIL AL e electric heaters are not designed for use in dusty, corrosive, or hazardous locations. Portions of the heater can get hot. Adequate protection must be taken to protect people from potential bums, and to protect other components from this heat. This heater can only be installed in a totally enclosed metal enclosure. 2001 Hoffman Enclosures Inc. 8758551 English WIRING (Reference Page 14) 1. All wiring must comply with applicable local codes and ordinances. 2. Connect the heater leadwires to the proper A.C. power source. Power source for 800 watt heaters should be continuous. 3. The heater must be properly grounded. NOTE: Exposed wires should not come in contact with the heater housing. MAINTENANCE 1. Always disconnect power supply before inspecting or working on the heater. 2. Generally the unit requires no maintenance since the fan bearings are permanently lubricated and sealed. .................. To avoid electric shock, do not energize any circuits before ail internal and external electrical and mechanical clearances are checked to assure that all assembled equipment functions safely and properly. 10 Thermostat Heating Element Wiring Schematic English Vertical Surface Mounting LOCATION AND MOUNTING Watts 7 1.
