Introduction 

 

Thank you for purchasing the 

  Thermodyne Steam Trap. 

 

This product has been thoroughly inspected before being shipped from the 
factory. When the product is delivered, before doing anything else, check the 
specifications and external appearance to make sure nothing is out of the 
ordinary. Also be sure to read this manual carefully before use and follow the 
instructions to be sure of using the product properly. 

 

The Thermodyne Steam Trap features a bimetal ring for thermostatic air 
venting, which allows the quick, automatic discharge of large quantities of 
initial air and cold condensate immediately after operation start-up, thereby 
greatly reducing start-up time.    It also reacts with great sensitivity to the 
inflow of large quantities of condensate and hot air during operation, 
preventing air binding. 

 

The modular valve seat unit is quickly and easily installed and replaced, thus 
greatly reducing the time and labor required for maintenance and repair. 

 

The Thermodyne Steam Trap, with its superior features listed above, in 
combination with the proven performance record of the bimetal thermostatic 
air vent, increases heating efficiency and reduces manpower requirements for 
maintenance and bypass blowdown. 

 

If detailed instructions for special order specifications or options not contained 
in this manual are required, please contact 

  for full details. 

 

This instruction manual is intended for use with the model(s) listed on the front 
cover. It is necessary not only for installation but for subsequent maintenance, 
disassembly/reassembly and troubleshooting. Please keep it in a safe place 
for future reference.
