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
When 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 float is damaged or filled with
condensate
Replace with a new float
The trap valve seat port, screen or
piping is clogged with rust or scale
Clean parts
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
Steam is discharged
or leaks from the trap
outlet
(blowing)
(steam leakage)
Rust and scale have accumulated
around the trap valve seat or beneath
the float
Clean parts
The trap valve seat is damaged
Replace with a new trap
valve seat
The float is deformed or coated with
scale
Clean or replace with a new
float
The separator is installed above the
maximum allowable inclination
Correct the installation
Steam is leaking
from sealing
surfaces
Gasket deterioration or damage
Replace with a new gasket
Improper tightening torques were used
Tighten to the proper torque
Water is mixed in
with the steam from
the separator outlet
Steam flow velocity is too high
Take steps necessary to
lower the steam flow velocity
Review causes
listed above in “No condensate is discharged…” and
follow the appropriate remedy
Separator outlet
pressure drops or
desired flow rate is
unachievable
The screen is clogged with rust and
scale
Clean or replace with a new
screen
