GENERAL

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

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

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.

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.
