CALORITECH™ TYPE PH ELECTRIC CONTROL PANEL ENCLOSURE HEATERS ARE FAN-FORCED AIR HEATERS DESIGNED TO CONTROL THE ENVIRONMENT WITHIN ENCLOSURES BY MAINTAINING A STABLE TEMPERATURE. EFFECTS OF LOW TEMPERATURES SUCH AS CORROSION FREEZING OR CONDENSATION WILL ADVERSELY AFFECT THE COMPONENTS INSIDE CONTROL PANELS. THE CALORITECH PH ENCLOSURE HEATER PROVIDES AN OPTIMAL PERFORMANCE ENVIRONMENT FOR THE CRITICAL COMPONENTS CONTAINED WITHIN THE CONTROL PANEL. HEATER SELECTION - THE WATTAGE REQUIREMENT IS DETERMINED FROM A CONSIDERATION OF THE SURFACE AREA INSULATION PROPERTIES OF THE ENCLOSURE OR SPACE AND THE TEMPERATURE DIFFERENCE BETWEEN THE AMBIENT AND THE ENCLOSURE. INSTALLATION - THE CALORITECH PH ENCLOSURE HEATER SHOULD BE INSTALLED IN THE CENTER OF THE CABINET AND AS LOW AS PRACTICAL FOR THE BEST POSSIBLE HEAT DISTRIBUTION. THE OPTIMUM EFFICIENCY IS OBTAINED WHEN THE UNIT IS MOUNTED IN A VERTICAL POSITION ALLOWING THE TOP AIR VENTS TO RELEASE THE HEATED AIR IN THE MOST EFFECTIVE MANNER. THE ENCLOSURES SHOULD BE SEALED AND FREE FROM DUST AND DIRT. DO NOT INSTALL THE HEATERS ON WOOD CARDBOARD OR OTHER FLAMMABLE PANELS. HEAT-SENSITIVE COMPONENTS SHOULD NOT BE PLACED NEAR THE HEAT DISCHARGE AREA. FOR LARGER ENCLOSURES TWO OR MORE HEATERS MAY BE USED.
