electric heating equipment. Where the conse-
quences of failure could result in personal injury or
property damage, back-up controls are essential.
FIRE HAZARD. An integral thermostat, if provided,
is designed for temperature control service only.
Because the thermostat does not fail safe, it should
not be used for temperature limiting duty. Wiring to
this device is the responsibility of the user.
FIRE/EXPLOSION HAZARD. Use only Explosion
Resistant Enclosures (E2, E3 or ER) in hazardous
atmospheres where flammable vapors, gases, liquids
or other combustible atmospheres are present as
defined in the National Electrical Code (NFPA 70).
Failure to comply could result in personal injury or
property damage.
The system designer is responsible for the safety
of this equipment and should install adequate
back-up controls and safety devices with their
INSTALLATION
7. 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.
8. A drip loop is recommended to minimize passage of moisture
along wiring into terminal enclosure and connections.
ELECTRIC SHOCK HAZARD. Disconnect all power
before installing or servicing heater. Failure to do
so could result in personal injury or property dam-
age. Heater must be installed by a qualified person
in accordance with the National Electrical Code,
NFPA 70.
FIRE HAZARD. Since heaters are capable of developing
high temperatures, extreme care should be taken to:
A. Use explosion-resistant terminal enclosures in hazardous loca-
tions. Consult Chromalox for selection of explosion-resistant
terminal enclosures for hazardous locations.
1. Before installing, check your Over-The-Side heater for any dam-
age that may have occurred during shipment. Also, check to ensure
that the line voltage is the same as that stamped on the nameplate.
2. Do not bend heating elements. If bending is necessary, consult factory.
3. IMPORTANT: Mount the 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 excessive sheath temperatures. See “Warning” under
“Installation” section. (see Figure 3).
B. Avoid contact between heater and combustible materials.
C. Keep combustible materials far enough away to be free of the
effects of high temperatures.
!
FREEZE HAZARD. Some Over-The-Side heaters are
equipped with a thermowell for process control or
over-temperature control. Do not allow moisture to
accumulate in thermowell. Freezing temperatures
can cause damage that may result in the heated
medium leaking into terminal enclosure.
4. Heater must be supported from tank bottom. Heater must not be
operated in sludge. Sludge legs can be provided. Assemble as
shown in Figure 3.
5. Where work will pass over or near equipment, additional protec-
tion, such as a metal guard, may be needed.
6. In the electroplating operation the heaters are not, under any cir-
cumstance, to be placed between the electrodes and the work.
4
INSTALLATION (cont’d.)
9. To prevent moisture accumulation in cryogenic applications or
when heater is exposed to freezing temperatures:
A. Slope conduit away from enclosure (drip loop).
B. Seal all conduit openings to moisture/explosion resistant ter-
minal enclosure.
FIRE OR EXPLOSION HAZARD. If the heater is not
properly submerged, the heating elements will over-
heat and could result in a fire or damaged equipment.
C. Insulate terminal enclosure.
NOTE: If heating in closed vessels, controls and
backup controls must be used to prevent buildup of
temperature and/or pressure. Maximum pressure
rating is 50 PSI.
FIRE OR SHOCK HAZARD. Moisture accumulation
in the element refractory material, element over-
temperature, or sheath corrosion can cause
ground fault to the element sheath, generating arc-
ing and molten metal. Install Ground Fault Circuit-
Interrupter (GFCI) to prevent personal injury or
Equipment Ground Fault Protection to prevent
property damage.
Suitable Wiring
Drip Loop recommended to
minimize passage of moisture
along wiring into terminal
wiring connections.
Expected Low Liquid Level
10. Heaters with floor flange:
A. Remove electrical enclosure.
B. Mount heater to tank or manhole cover.
C. Install electrical enclosure.
6 to 8"
Always maintain a minimum of
Minimum
6 to 8" of liquid above the heated
portion of the element to prevent
exposure of the effective
heated length.
!
Expected maximum
Fittings into electrical enclosure must be properly
sealed to prevent contamination of electrical con-
tacts from vapors.
Sludge Legs
sediment level
NOTE: Locate the heater as low as possible for maximum
heated liquid storage capacity. Heat does not move downward.
FIGURE 3 Open Tank Illustration
WIRING
6. Heaters are prewired and tagged for easy installation of electrical
wiring to the heater. Tagging of the individual circuits of
Chromalox Industrial Over-The-Side Immersion heaters is shown
in the following tabulations. Refers to Type TLC, TLO, TLS, TLI,
KTLC, KTLO, KTLS, KTLI, KBLC, KBLS, BLCK, and BLCS
Series heaters.
7. Make sure heater, is grounded by attaching ground conductor,
traceable back to service entrance, to the ground terminal located
inside the terminal enclosure. If heater is used in an electroplating
tank, the heater should be grounded externally to the tank wall to
minimize stray plating currents in heater sheath that may cause
sheath corrosion.
ELECTRIC SHOCK HAZARD. Any installation involv-
ing electric heaters must be performed by a quali-
fied person and must be effectively grounded in
accordance with the National Electrical Code to
eliminate shock hazard.
1. Electric wiring to heater must be installed in accordance with the
National Electrical Code and with local codes by a qualified per-
son. CAUTION: Use copper conductors only.
2. When element wattages are not equal, heaters must not be con-
nected in series.
8. Check for loose terminal connections and tighten if necessary.
Made to order items are prewired and tagged at the factory. Wiring
of made to order items may differ from those shown in the tabu-
lations. Carefully check voltage and phase on the heater name-
plate and select either the appropriate wiring shown above or
check for the appropriate wiring diagram in the heater termi-
nal enclosure. For reference purposes, some typical wiring dia-
grams are shown in the following figures.
3. Electrical wiring to heater should be contained in rigid conduit or
in sealed flexible conduit to keep corrosive vapors and liquids out
of the terminal enclosure. If high humidity is encountered, the con-
duit should slope away from the heater.
4. If flexible cord is employed, a watertight connector should be used
for entry of the cord into the terminal enclosure. Outdoor applica-
tions require liquid-tight conduit and connectors.
5. Bring the power line wires through the opening in the terminal
enclosure.

OPERATION
1. Do not operate heater at voltages in excess of that stamped on the
assemblies or 20 megohm on individual unsealed elements. It is
recommended that heaters with 1 megohm or less be dried out
before applying full power. If dried properly, low megohm will not
effect heater life or efficiency.
To correct a low megohm condition, remove terminal enclosure
cover, gaskets, and terminal hardware. Bake heaters in an oven at
300 to 500˚F for several hours or preferably overnight.
An alternate procedure is to cycle the heater in 10 to 15 minute
periods at low voltage until megohm values are normal. Sheath
temperatures should not exceed 350˚F.
heater since excess voltage will shorten heater life.
2. Always maintain a minimum of 6 to 8” of liquid above the heated
portion of the element to prevent exposure of the effective heated
length. If the heater is not properly submerged, it will overheat and
shorten heater life. DO NOT OPERATE HEATER IF DRY.
3. Keep heating elements above sediment deposits.
4. Low Megohm Condition — The refractory material used in elec-
tric heaters may absorb moisture during transit, storage or when
subject to humid environments that will reduce the cold insulation
resistance (low megohm). Low megohm may result in a high leak-
age current to ground and nuisance trips of ground fault protection
equipment. Normally, the megohm value increases after heat-up.
Typical insulation valves are 5 megohm or greater on complete
NOTE: Low megohm on heating elements with epoxy or hermetic
seals cannot be serviced in the field. Typical resistance val-
ues when sealed are 200 megohm or greater. Contact Chro-
malox service center at number listed.

MAINTENANCE
Note: User is responsible for maintenance schedule based on their
knowledge of the heated medium and operating conditions.
3. Remove any accumulated sludge deposits from heater and from
tank.
ELECTRIC SHOCK HAZARD. Disconnect all power
before installing or servicing heater. Failure to do so
could result in personal injury or property damage.
4. Check for loose terminal connections.
5. If corrosion is indicated in the terminal enclosure, check termi-
nal enclosure gasket and replace if necessary. Check conduit
layout to correct conditions that allow corrosion to enter the ter-
minal enclosure.
1. Heaters should be checked periodically for coatings and corrosion
and cleaned if necessary.
2. The tank should be checked regularly for sediment around the
heater as sediment can act as an insulator and shorten heater life.
Note: Applies to all items, not just #2.
6. Clean terminal ends of all contamination.
