Notes for using and installing the heater:
a)Heater should be protected againest damp during storing or installing to ensure the performance of the henter.
b)In order to be sure of well-distributed lod of each and groups heater shoud be divided before assembling. The tolerance of the resistance of each one can not exceed by 10% each other.
c)Heater is hard and brittle, please be careful when assem bling and maintaining so as to avoid damage.
d)When operating the electric furnace at the beginning, the voltage should be increased slowly and can not be fully loaded at once. Otherwise the larger current will be resulted in the damage of heater.
e)When heater is damaged and need to be changed , the resistance of new ne should follow the increasing resistance. If many are damaged or resistance increased too much, akk heater should be changed.

Advantages:
l. Withstands as high as 1600 (surface temperature of sic heater)
2.Generates high heat output per unit surface area, approximately 5-10 times the output of nichrome wire.
3.It is chemically very stable.
4.Heat source is free of noise and air pollution.
5.It has high strength and excellent shock resistance.
