Introduction 

 

Thank you for purchasing the 

  Free Float 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. 

This free float steam trap employs a hinge-less and lever-less free float to rapidly, 
automatically and continuously discharge the inflowing condensate that is continuously 
generated inside the equipment, thus preventing the accumulation of condensate and 
thereby improving the heat transfer efficiency of the equipment. In addition, the integral 
bimetal type automatic air vent allows for the rapid release of start-up air and thereby 
reduces start-up time. 
These features make this free float steam trap ideally suited for use on process systems 
and equipment (steam-using equipment), and it is especially well-suited for removing 
condensate from equipment used for batch operations, which often experience entrained 
air during operation.

 

 

This steam trap also employs a precision-ground float and three-point seating that 
supports the float securely at three points and ensures a high degree of sealing when 
even only minute quantities of condensate are present.   
This free float steam trap is also ideal for places at which extremely small amounts of 
condensate are generated, such as superheated and saturated steam mains and 
branches, and trace lines. 
 
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.
