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
When the trap fails to operate properly, use the following table to locate the cause.
Problem Cause Remedy
Check the module valve seat, screen and
piping to see if they are clogged with rust
or scale Clean parts
Check to see if the disc is stuck to the
module valve seat Clean parts
Check to see if air-locking has occurred Perform a bypass blowdown,
or close the trap inlet valve

Air-locking has occurred due to disc
holder ring and or air vent ring wear Replace with new disc holder
ring or air vent ring
Check to see if steam-locking has
occurred Perform a bypass blowdown,
or close the trap inlet valve
and allow the trap to cool
No condensate
is discharged
or discharge is
poor
(blocked)
Check to see if 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
Check to see if there is rust or scale on
the disc or on the module valve seat Clean parts
Check the disc and the module valve
seat for damage or wear Replace with new disc or
