Chromalox KBLC Installation Instructions

RENEWAL PARTS IDENTIFICATION
Note: Consult factory for specific installation instructions for heaters with additional features not detailed in this installation guide.
Chromalox Type KBL over-the-side immersion heaters are pri-
marily designed for use in drums containing wax, lard, grease, coconut
oil and other heat-sensitive materials having low melting-points.
1. Heater Construction Characteristics
A. High-quality Nichome resistance wire held in place by com-
pacted Magnesium Oxide in either steel sheath (most applica-
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
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.

GENERAL
result of operating conditions beyond our control.
B. Low watt density.
C. Steel terminal box painted with heat and acid-resistant paint.
D. Lightweight and portable yet heavy-duty. (Weighs only 18
lbs. or less).
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, back-up controls are essential. Although the
safety of the installation is the responsibility of the
user, Chromalox will be glad to make equipment
recommendations.
INSTALLATION
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.
