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 and
remedy the cause.
Problem
Cause
Remedy
No condensate
is discharged or
discharge is
poor
(blocked)
The float is damaged or filled with
condensate
Replace with new float
The valve seat opening, screen or
piping are clogged with rust and 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
Air binding has occurred (standard
installation)
Inlet piping must be at least
15 mm (
1
/
2
in), straight, vertical
and as short as possible
Air binding has occurred (horizontal
inlet piping was used)
Use only vertical inlet piping if
possible, otherwise install a
pressure-balancing line
The specific gravity of the fluid is not
suitable for this product
Consult TLV
Air/gas is
discharged or
leaks from the
outlet*
(blowing)
(air/gas
leakage)
Rust and scale have built-up around the
valve seat or beneath the float
Clean parts
The valve seat is scratched or damaged Replace with new valve seat
The float is misshapen or has a build-up Clean float or replace with new
float
Improper installation orientation
Correct the installation
There is excessive trap vibration
Lengthen inlet piping and
fasten securely
Air/gas is
leaking from a
place other
than the outlet
Gasket(s) are deteriorated or damaged Replace with new gasket(s)
Improper tightening torques were used Tighten to the proper torque
* The SS1VG–M with metal valve seat has a minimum condensate load requirement to
ensure proper sealing (see “Specifications”).
