GENERAL  
1. Heater Construction Characteristics  
WARNING: 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.  
A. High quality resistance wire held in place by compacted  
magnesium oxide in stainless steel sheath.  
B. Medium Watt Density.  
C. Light weight and low profile.  
D. Manual rest cutout to shut off heater in an overtemperature  
condition is standard.  
Chromalox type PTHF over-the-side immersion heaters are  
especially suited for heating corrosive solutions to 212˚F.  
WARNING: Users should install adequate controls and safety  
devices with their electric heating equipment. Where the conse-  
quences 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 recommenda-  
tions.  
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 corro-  
sive solution, character of the materials entering 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.  
INSTALLATION  
3. WARNING: Mount heater in the tank so the liquid level will  
always be above the effective heated portion of the heater. If  
heater is not properly submerged, it will overheat and damage  
the heating elements and create a possible fire due to exces-  
sive sheath temperature.  
WARNING: Hazard of Electrical Shock. Disconnect all  
power before installing heater.  
1. WARNING: Do not scrape or scratch thermal cutout capil-  
lary on heating elements. Damage could result.  
2. Before installing the type PTHF heater, inspect it for possible  
damage which may have occurred during shipment. Also, check  
to insure the line voltage is the same as that on the nameplate.  
4. In an electroplating operation the heaters are not, under any  
circumstance, to be placed between the electrodes and the work.
