Troubleshooting
When disassembling or removing the product, wait until the internal
pressure equals atmospheric pressure and the surface of the product
has cooled to room temperature. Disassembling or removing the
product when it is hot or under pressure may lead to discharge of fluids,
causing burns, other injuries or damage.
CAUTION
If the product fails to operate properly, use the following table to locate the cause and
remedy.
Problem
Cause
Remedy
No condensate is
discharged (blocked)
or discharge is poor
The screen or inlet/outlet channels on
the connector body are clogged with
rust and scale
Clean
The trap operating pressure exceeds
the maximum specified pressure, or
whether there is insufficient pressure
differential between the trap inlet and
outlet
Compare specifications and
actual operating conditions
Steam-locking has occurred
Perform a bypass blowdown
or close the trap inlet valve
and allow the trap to cool
Steam is discharged
or leaks from the
outlet
(blowing)
(steam leakage)
Improper installation orientation
Correct the installation
Excessive trap vibration
Lengthen the inlet piping and
fasten it securely
Water hammer has occurred
Examine for problems that
can cause water hammer and
correct the piping
Steam is leaking
from a place other
than the outlet
The gaskets have deterioration or
damage
Replace with new gaskets
Improper tightening torque was used
Tighten to the proper torque
