Introduction
Thank you for purchasing the Free Float Steam Trap.
This product has been thoroughly inspected before being shipped from the factory. When
the product is delivered, before doing anything else, check the specifications and
external appearance to make sure nothing is out of the ordinary. Also be sure to read this
manual carefully before use and follow the instructions to be sure of using the product
properly.
This free float steam trap employs a hinge-less and lever-less free float to rapidly,
automatically and continuously discharge the inflowing condensate that is continuously
generated inside the equipment, thus preventing the accumulation of condensate and
thereby improving the heat transfer efficiency of the equipment.
This steam trap is also of a revolutionary design featuring an integral air vent that
employs a high-performance X-element. The X-element is very sensitive to changes in
temperature, and responds with great accuracy. As a result, air and the large quantities
of condensate created immediately after the start-up of operation are quickly discharged,
thereby greatly reducing start-up time and also proving useful in valve operation (bypass
blowdown) labor-saving.
The X-element is also sensitive to hot air during operation, responding quickly and thus
preventing the occurrence of air binding.
These features make this free float steam trap ideally suited for use on process systems
and equipment (steam-using equipment), and it is especially well-suited for removing
condensate from equipment used for batch operations, which often experience entrained
air during operation.
If detailed instructions for special order specifications or options not contained in this
manual are required, please contact for full details.
This instruction manual is intended for use with the model(s) listed on the front cover. It is
necessary not only for installation but for subsequent maintenance, disassembly/reassembly
and troubleshooting. Please keep it in a safe place for future reference.

Checking the Piping
Use only under conditions in which no water hammer will occur. The
impact of water hammer may damage the product, leading to fluid
discharge, which may cause burns or other injury.
CAUTION
Check to make sure that the pipes to be connected to the trap have been installed
properly.
1. Is the pipe diameter suitable?
2. Is the piping where the trap is to be installed horizontal?
3. Has sufficient space been secured for maintenance?
4. Have isolation valves been installed at the inlet and outlet? If the outlet is subject
to back pressure, has a check valve (TLV-CK) been installed?
5. Is the inlet pipe as short as possible, with as few bends as possible, and installed
so the liquid will flow naturally down into the trap?
6. Has the piping work been done correctly, as shown in the figures below?
Requirement
Correct
Incorrect
Install catchpot with the
proper diameter.
Diameter is too small.
Make sure the flow of
condensate is not
obstructed.
Diameter is too small and inlet
protrudes into pipe interior.
To prevent rust and scale
from flowing
into the trap, the
inlet pipe should be
connected 25 – 50 mm (1”–
2”) above the base of the
T-pipe.
Rust and scale flow into the
trap with the condensate.
When installing on the blind
end, make sure the flow of
condensate is not
obstructed.
Condensate collects in the
pipe.

Operation
Principles of air and condensate discharge:
1. Start-up Air and Cold Condensate
Discharge
At start-up, before steam is supplied, the trap is
cold so the X-element is contracted and the air
vent valve seat (A) is open. This allows for the
rapid discharge of air through the air vent valve
(A) and cold condensate through the orifice (B),
when steam is first supplied to the system.
2. Condensate Discharge
After the discharge of initial air and cold
condensate, the heat of the inflowing steam and
condensate causes the X-element to expand,
closing the air vent valve (A). The rising
condensate level causes the float to rise due to
buoyancy, opening the orifice (B) and allowing
condensate to be discharged.
3. Hot Air Discharge
Should hot air flow into the trap with the steam
during normal operation, the temperature of the
X-element drops, causing it to momentarily
contract and open the air vent valve (A), which
allows for the rapid discharge of the air. After the
air is discharged and steam contacts the
X-element, the temperature will increase
causeing the air vent valve (A) to close
4. Closed Position
When the condensate flow rate decreases, the
X-element expands due to the heat of the steam,
closing the air vent valve (A). In addition, the float
falls as condensate is discharged, closing off the
orifice (B). A water seal is maintained at all times
over the orifice (B) to prevent steam loss.

or other injury due to malfunction or the discharge of fluids.
CAUTION
Operational Check
A visual inspection of the following items should be done on a daily basis to
determine whether the trap is operating properly or has failed. Periodically (at least
biannually) the operation should also be checked by using diagnostic equipment,
such as a stethoscope, thermometer, TLV Pocket TrapMan or TrapMan.
If the trap should fail, it may cause damage to piping and equipment, resulting in
faulty or low quality products or losses due to steam leakage.
Normal
:
Condensate is discharged continuously, together with flash steam,
and the sound of flow can be heard. If there is very little condensate,
there is almost no sound of flow.
Blocked
(Discharge Impossible)
:
No condensate is discharged. The trap is quiet and makes no noise,
and the surface temperature of the trap is low.
Blowing
:
Live steam continually flows from the outlet and there is a
continuous metallic sound.
Steam Leakage
:
Live steam is discharged through the trap outlet together with
condensate, accompanied by a high-pitched sound.
(When conducting a visual inspection, flash steam is sometimes mistaken for steam leakage. For
this reason, the use of a steam trap diagnostic instrument [TLV: TrapMan] in conjunction with the
visual inspection is highly recommended.)

Instructions for Plug / Holder Disassembly and Reassembly
The seal on the threaded plugs/holders found on TLV products is formed by a flat
metal gasket. There are various installation orientations for the gaskets, such as
horizontal, diagonal and downward, and the gasket may be pinched in the thread
recesses during assembly.
Instructions for Disassembly and Reassembly
①Remove the plug/holder using
a tool of the specified size
(distance across flats).
②The gasket should not be
reused. Be sure to replace it
with a new gasket.
③Clean the gasket surfaces of
the plug/holder and the product
body using a rag and/or
cleaning agents, then check to
make sure the surfaces are not
scratched or deformed.
④Coat both the gasket surface
of the plug/holder and the
threads of the plug/holder with
anti-seize, then press the
gasket onto the center of the
gasket surface of the
plug/holder, making sure the
anti-seize affixes the gasket
tightly to the plug/holder.
Check to make sure the
gasket is not caught in the
recesses of the threads.
⑤Hold the plug/holder upside down to make sure that the anti-seize makes the
gasket stick to the plug/holder even when the plug/holder is held upside down.
⑥Screw the plug/holder by hand into the product body while making sure that the
gasket remains tightly affixed to the center of the gasket surface of the
plug/holder. Make sure the entire gasket is making contact with the gasket
surface of the product body. It is important at this point to make sure the gasket
is not pinched in the thread recesses of the plug/holder.
⑦Tighten the plug/holder to the proper torque.
⑧Next, begin the supply of steam and check to make sure there is no leakage
from the part just tightened. If there is leakage, immediately close the inlet valve
and, if there is a bypass valve, take the necessary steps to release any residual
pressure. After the surface of the product cools to room temperature, repeat the
procedure beginning from step 1.
