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 intermittently together with flash
steam, and the sound of flow can be heard.
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 product 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 if
appropriate] in conjunction with the visual inspection is highly recommended.)
