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 uses a precision-polished float and three-point support
for the valve body. With no hinges or levers, the trap automatically continuously
discharges condensate, preventing it from collecting. The three-point seating for
the valve body supports the precision-polished float securely at three points and
ensures a high degree of sealing for even minute quantities of condensate.
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 ham mer 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 (SS3N / SS5N / SS5NH) or
vertical (SS3V / SS5V / SS5VH)?
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
in) 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
system is cold and the bimetal air vent strip
is expanded, holding the float off of the
orifice. This allows for the rapid discharge
of air and cold condensate through the
orifice when steam is first supplied to the
system. After the discharge of initial air and
cold condensate, the heat of the inflowing
steam and condensate cause the bimetal
air vent strip to contract.
2. Condensate Discharge
As steam is supplied, condensate flow
begins. The rising condensate level causes
the float to rise due to buoyancy, opening
the orifice and allowing condensate to be
discharged.
3. Closed Position
When the condensate flow rate decreases,
the float falls, closing off the orifice
opening. A water seal is maintained at all
times over the orifice to prevent steam loss.

Maintenance
Take measures to prevent people from coming into direct contact with
product outlets. Failure to do so may result in burns or other injury from
the discharge of fluids.
CAUTION
Be sure to use only the recommended components when repairing the
product, and NEVER attempt to modify the product in any way. Failure to
observe these precautions may result in damage to the product or burns
or other injury due to malfunction or the discharge of fluids.
CAUTION
Operational Inspection
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 TLV 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 [such as TLV TrapMan if appropriate]
in conjunction with the visual inspection is highly recommended.)
