Chromalox PTHT-101 Installation, Operating And Maintenance Instructions

Maintenance Instructions

Titanium Over-the-Side Immersion Heater
4-3/4"
DANGER: This heater is not intended for use in haz-
ardous atmospheres where flammable vapors,
gases, liquids or other combustible atmospheres are
present as defined in the National Electrical Code.
Failure to comply can result in explosion or fire.
Chromalox type PTHT over-the-side immersion heaters are
especially suited for use in plating tanks, rinse tanks and other
aqueous solutions.
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 solution, and controls
which he maintains on the process. Chromalox
cannot warrant any electric immersion heater
WARNING: Hazard of Electrical Shock. Disconnect all
power before installing heater.
1. Before installing the type PTHT heater, inspect it thoroughly for
possible damage which may have occured during shipment. Also
check to insure that the line voltage is the same as that stamped
on the heater nameplate.
2. Where work will pass over or near equipment, additional pro-
tection such as a metal guard may be needed.
3. To resist buoyancy and to keep the heater in close profile with
tank wall, a metal bracket with two mounting holes has been
provided.

GENERAL
against failure by sheath corrosion if such failure
is the result of operating beyond our control.
1. Heater construction characteristics.
A. High quality resistance wire held in place by compacted
magnesium oxide in titanium sheath.
B. Medium watt densities.
C. Vapor tight junction box with 3' PVC flexible conduit with
ground wire.
D. Spacer bar prevents elements from touching tank wall.
E. Flat profile consumes little tank work area.
WARNING: Users should install adequate controls and safe-
ty devices with their electric heating equipment. 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. WARNING: Heated section (See Figure 1, "B" Dimension)
must be totally immersed at all times. If the heater is not properly
submerged, it will overheat and damage the heating element and
create a possible fire hazard due to excessive sheath temperatures.
5. Heater must not be operated in sludge.
6. DANGER: 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 materials.
C. Keep combustible materials for enough away to be free of
the effects of high temperatures.
