Maintenance
Caution
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.
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 and burns or other injury due to malfunction or the discharge of fluids.
Operational Check
A visual inspection of the following items should be done on a daily basis to determine
whether the product 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 TLV TrapMan.
If the product 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 product is quiet and makes no noise, and the
surface temperature of the product 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 such as TLV TrapMan in
conjunction with the visual inspection is highly recommended.)

inspect the parts and replace any that are found to be defective.
