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 orifice opening, screen or piping are
clogged with rust and scale
Clean parts
The bimetal plate is damaged
Replace with a new bimetal
plate
Steam-locking has occurred
Operate the lock release valve
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)
The orifice opening is clogged or there is
rust and scale build-up beneath the float
Clean parts
The orifice is scratched or damaged
Replace with a new orifice
The float is misshapen or has buildup
Clean or replace float
Improper installation orientation
Correct the installation
Trap vibration
Lengthen inlet piping and
fasten securely
The air vent valve plug and/or the air
vent valve seat has buildup or is
scratched
Clean or replace the air vent
valve plug/bimetal plate and/or
the air vent valve seat
The bimetal plate is damaged
Replace with a new bimetal
plate
The lock release valve is holding the air
vent valve plug open
If steam-binding had occurred,
this is normal; otherwise adjust
the lock release valve to allow
the air vent to close
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
