Mica insuated band heaters Instaation and storage instruction Instaation When instaing the mica band heater, pease make sure to hod it tighty screwing up the apposite bots (with exagona head). When reached the working temperature or after 30 min. heating screw it up sti further. Do the same after few hours in order to compensate the therma inear expansion of the heater. Not doing the operation described above may cause the over heating of the parts of the heater that are not perfecty in contact with the nozze pointed out by a coour change purpe - back and consequenty the resistive fiament may burn. Storage Store at room temperature in a dry pace. Operation Security procedures for the handing of eectrica items and appications must be foowed Do not touch mica heater bands whie in use because the can get very hot Pease make sure that the heating eements can not touch fammabe materia whie in use It is very important to foow these advices in order to have a onger ifetime of the heater Genera information If our mica bands heater are deivered with feeding cabes without insuation (naked connection) or with removabe insuation (covered with gs-seeving) the customer himsef has to take care about the protection against eectricity. Connections Protect connections against the ingress of iquids and gases to avoid short circuits Insta the connections away from sharp edges or parts since this may aso cause short circuits Protect connection eads against the effects of temperature and ay them in a proper way Pay attention to the connection votage Temperature controers Temperature controers have to match the power consumption and the used temperature sensor. Ony insta temperature controers with automatic soft start function so that any moisture which may have entered the heating eement wi escape sowy 7
