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 product is operating properly or has failed. Periodically (at least
biannually) the sound of operation and the trap surface temperature should also be
checked by using diagnostic equipment, such as a stethoscope or thermometer. A
complete disassembly and inspection should be performed at least once every 3
years.
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 and there is no leakage
when the valve is closed. After the sound of the flow of condensate
continues for some time, the sound of the valve closing on the
valve seat can be heard. This is followed by an interval in which
the trap makes no sound, after which the cycle is again repeated.
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 product outlet together with
condensate, accompanied by a high-pitched sound.

Live Steam Leakage
