Maintenance 

 

 

Take measures to prevent people from coming into direct contact with 

product outlets. Failure to do so may result in burns or other injury from 

the discharge of fluids.

 

CAUTION 

 

 

Be sure to use only the recommended components when repairing the 

product, and NEVER attempt to modify the product in any way. Failure to 

observe these precautions may result in damage to the product or burns 

or other injury due to malfunction or the discharge of fluids.

 

CAUTION 

 

Operational Check 

A visual inspection of the following items should be done on a daily basis to 
determine whether the trap is operating properly or has failed. Periodically (at least 
biannually) the operation should also be checked by using diagnostic equipment, 
such as a stethoscope, thermometer, TLV Pocket TrapMan or TrapMan. 

If the trap should fail, it may cause damage to piping and equipment, resulting in 
faulty or low quality products or losses due to steam leakage.   

Normal                         

:  Condensate is discharged continuously, together with flash steam, 

and the sound of flow can be heard. If there is very little condensate, 
there is almost no sound of flow. 

Blocked                     
(Discharge Impossible) 

:  No condensate is discharged. The trap is quiet and makes no noise, 

and the surface temperature of the trap is low. 

Blowing                       

:  Live steam continually flows from the outlet and there is a 

continuous metallic sound.   

Steam Leakage   

:  Live steam is discharged through the trap outlet together with 

condensate, accompanied by a high-pitched sound. 

(When conducting a visual inspection, flash steam is sometimes mistaken for steam leakage. For 
this reason, the use of a steam trap diagnostic instrument [TLV: TrapMan] in conjunction with the 
visual inspection is highly recommended.)

Parts Inspection 

When parts have been removed, or during periodic inspections, use the following 
table to inspect the parts and replace any that are found to be defective. 

Procedure

 

Gaskets: check for warping or scratches 
Screen: check for clogging or corrosion 
X-element, Air Vent Valve Seat: check for scratches 
Float: check for scratches or dents 
Check for build-up inside the body 
Orifice Opening: check for dirt, oil film, wear or scratches
