Introduction
Thank you for purchasing the TLV process 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.
The process float steam trap is a large-capacity lever float type mechanical
steam trap that uses a high-performance X-element or high-temperature
bimetal for the air vent. With the unique sensitivity of mechanical steam traps
for condensate discharge, the trap reduces the time required to start up
process equipment and improves heating efficiency.
For products with special order specifications or options, if detailed
instructions for the special order specifications or options are not contained in
this manual, please contact TLV 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.

Indicates a DANGER, WARNING or CAUTION item.
Indicates an urgent situation which poses a threat of death or
serious injury
Indicates that there is a potential threat of death or serious injury
Indicates that there is a possibility of injury or equipment / product
damage
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.
Install properly and DO NOT use this product outside the
recommended operating pressure, temperature and other
specification ranges.
Improper use may result in such hazards as damage to the product
or malfunctions that may lead to serious accidents. Local
regulations may restrict the use of this product to below the
conditions quoted.
DO NOT use this product in excess of the maximum operating
pressure differential.
Such use could make discharge impossible (blocked).
Use hoisting equipment for heavy objects (weighing
approximately 20 kg (44 lb) or more).
Failure to do so may result in back strain or other injury if the object
should fall.
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.
Safety Considerations
Read this section carefully before use and be sure to follow the instructions.
Installation, inspection, maintenance, repairs, disassembly, adjustment and valve
opening/closing should be carried out only by trained maintenance personnel.
The precautions listed in this manual are designed to ensure safety and prevent
equipment damage and personal injury. For situations that may occur as a result
of erroneous handling, three different types of cautionary items are used to
indicate the degree of urgency and the scale of potential damage and danger:
DANGER, WARNING and CAUTION.
The three types of cautionary items above are very important for safety: be sure to
observe all of them as they relate to installation, use, maintenance, and repair.
Furthermore, TLV accepts no responsibility for any accidents or damage occurring
as a result of failure to observe these precautions.

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.
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 and burns or other injury due to malfunction or the
discharge of fluids.
Do not use excessive force when connecting threaded pipes to
the product.
Over-tightening may cause breakage leading to fluid discharge,
which may cause burns or other injury.
Use only under conditions in which no freeze-up will occur.
Freezing may damage the product, leading to fluid discharge, which
may cause burns or other injury.
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.

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.
Install catchpot with the proper
diameter.
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.
Checking the Piping
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 (refer to the “Installation”
section)?
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?
