Troubleshooting
NEVER apply direct heat to the float. The float may explode due to
increased internal pressure, causing accidents leading to serious injury
or damage to property and equipment.
WARNING
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 and remedy
the cause.
Problem
Cause
Remedy
No condensate is

Replace with a new float
The orifice opening, screen or piping are
clogged with rust and scale
Clean parts
The X-element is scratched or damaged Replace with a new X-element
Steam-locking has occurred
Perform a bypass blowdown or
close the trap inlet valve and
allow the trap to cool
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 is
discharged or leaks
from the outlet
(blowing)
(steam leakage)
Build-up on the seating surface of the
orifice or rust and scale build-up beneath
the float
Clean parts
Scratches on the orifice
Replace with a new orifice
The float is misshapen or has a build-up Clean or replace with a new
float
Improper installation orientation
Correct the installation
Trap vibration
Lengthen the inlet piping and
fasten it securely
The air vent valve seating area of the
X-element and/or air vent valve seat
have a build-up or are scratched
Clean the air vent valve seating
area of the X-element and/or
air vent valve seat or replace
the X-element unit
Steam is leaking
from a place other
than the outlet
Gasket deterioration or damage
Replace with new gasket(s)
Improper tightening torques were used
Tighten to the proper torque
Float frequently
becomes damaged
Water hammer has occurred
Study and correct the piping
