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 the cause and
remedy.
Problem

The float is damaged or filled with
condensate
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
The product operating pressure
exceeds the maximum specified
pressure, or there is insufficient
pressure differential between the
product 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)
Clogged orifice opening or regulation
valve opening, 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 surface
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 regulation valve is opened
Close the regulation valve
The X-element and/or air vent valve
seat have surface build-up or are
scratched
Clean or replace with a new
X-element/ air vent valve seat

from the gland of
the regulation valve
The gland retainer nut is loose
Re-tighten the gland retainer
nut or replace with a new
regulation valve unit
The regulation valve
does not move
The regulation valve is clogged with
rust and scale
Clean parts or replace with a
new regulation valve 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
