tions) or stainless steel sheath (corrosive applications).
WARNING: It is the responsibility of the purchaser of the heater to make the ultimate choice of sheath material based upon his knowledge of the chemical composition of the corrosive solution, character of the materials entering the solution, and controls which he maintains on the process. Chromalox can- not warrant any electric immersion heater against failure by sheath corrosion if such failure is the
result of operating conditions beyond our control.
B.Low watt density.
C.Steel terminal box painted with heat and
D.Lightweight and portable yet
E.Riser type construction puts the heat at the bottom inducing natural “stirring action” and evenly distributed tempera- tures.
WARNING: Users should install adequate controls and safety devices with their electric heating equip- ment. Where the consequences of failure may be severe,
INSTALLATION
WARNING: Hazard of Shock. Disconnect all power before installing heater
1.Before installing the type KBL heater, inspect it for possible dam- age which may have occurred during shipment. Also, check to insure that the line voltage is the same as that stamped on the nameplate.
2.IMPORTANT: Mount heater in the tank so that the liquid level will always be above the effective heated portion of the heater. If the heater is not properly submerged, it will overheat and damage the heating elements and create a possible fire hazard due to exces- sive sheath temperatures. (See Note 5)
3.Where work will pass over or near equipment, additional protec- tion, such as a metal guard, may be needed.
4.In an electroplating operation the heaters are not, under any cir- cumstance, to be placed between the electrodes and the work.
5.When melting solids by direct immersion, a surface vent should be provided to allow gases to escape. Operate the heater on half volt- age until melted material completely covers the heater area.
6.A drip loop is recommended to minimize passage of moisture along wiring into terminal box and connections.
7.WARNING: Hazard of Fire. Since these heaters are capable of developing high temperatures, extreme care should be taken to:
A.Avoid installing heaters in an atmosphere containing com- bustible gases and vapors.
B.Avoid contact between heater and combustible material. Keep combustible materials far enough away to be free of the effects of high temperatures.
