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 trap fails to operate properly, use the following table to locate the cause and
remedy.
Problem Cause Remedy
The trap operating pressure
exceeds the maximum specified
pressure or there is insufficient
pressure differential between the
trap inlet and outlet
Compare specifications and
actual operating conditions
The piping is clogged with rust and
scale
Clean the piping
The capacity of the trap is
insufficient
Compare specifications and
actual operating conditions
No condensate is
discharged (blocked) or
discharge is poor
Steam-locking has occurred
Perform a bypass blowdown or
close the trap inlet valve and
allow the trap to cool
Improper installation orientation
Correct the installation
Steam is discharged or
leaks from the outlet
(blowing) (steam leakage)
Trap vibration
Lengthen the inlet piping and
fasten it securely
Steam is leaking from a
place other than the outlet
The outside of the trap has
sustained damage
Replace with a new trap
Float becomes damaged
Water hammer has occurred
Study and correct the piping
