Introduction
Thank you for purchasing the TLV clean 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 clean steam trap is suitable for applications requiring condensate discharge from steam
transport lines, process systems and equipment (steam-using equipment). This clean steam
trap 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.
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.

Safety Considerations for the Product
Warning
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.
Caution
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.
Caution
DO NOT use this product in excess of the maximum operating pressure differential. Such
use could make discharge impossible (blocked).
Caution
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 and burns or other injury due to malfunction or the discharge of fluids.
Caution
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.
4

Caution
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.

Operation
Principles of air and condensate discharge:
1. Initial Air Discharge
At start-up, before steam is supplied the system is cold and air occupies the system.
When steam is first supplied to the system, air is discharged through the drain hole (B)
while the orifice (A) is closed by the float.
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 (A) and allowing condensate to be
discharged. In this manner, continuous condensate discharge occurs while the opening
size of the orifice varies depending on the condensate flow rate.
3. Discharge of Large Quantities of Condensate
Increases in the condensate inflow rate cause the condensate level in the trap to rise.
The float consequently rises and enlarges the opening of the orifice (A), allowing more
condensate to be discharged.
6

4. Closed Position
When the condensate flow rate decreases, the float falls, closing off the orifice opening
(A). When condensate flow rate becomes less than the minimum amount of condensate
required to prevent steam discharge, some amount of steam is discharged from the
drain hole (B). Once the system stops operating, condensate remaining in the trap drains
through the drain hole (B) by gravity.

Installation
Caution
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.
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.
Installation, inspection, maintenance, repairs, disassembly, adjustment and valve opening/
closing should be carried out only by trained maintenance personnel.
1. Before installation, be sure to remove all protective seals.
2. Before installing the product, blow out the inlet piping to remove any piping scraps, dirt
and oil. Close the inlet valve after blowdown.
3. Install the product vertically with the inlet at the top and the outlet at the bottom within
the allowable inclination as shown below, and with the arrow on the body pointing in the
direction of flow.
4. Install condensate outlet valve and outlet piping.
5. The outlet pipe should lead to a safe place such as a drainage vessel, pit, etc. Make sure
the end of the pipe is above the water level, so that dirt and water cannot be sucked up by
vacuum when the system shuts down.
6. Open the inlet and outlet valves and check to make sure that the product functions
properly.
7. After steam has passed through the piping, allow the trap to cool by closing the inlet valve
and then further tighten the clamp.
8. Open the inlet valve again for normal operation.
If there is a problem, determine the cause using the “Troubleshooting” section in this manual.
Tolerance Angle for Installation: 5°
Make sure the product is installed with the raised TLV lettering on the cover horizontal.

Maintenance
Caution
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.
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.
Operational Check
A visual inspection of the following items should be done on a daily basis to determine
whether the product 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 product should fail, it may cause damage to piping and equipment, resulting in faulty or
low quality products or losses due to steam leakage.
Normal: During either intermittent or continual condensate discharge flash
steam is discharged and the sound of flow can be heard.
Blocked (Discharge
Impossible): No condensate is discharged. The product is quiet and makes no noise, and the surface temperature of the product 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.
Note
The SS3-E/SS3-P/SS3-EP/SS5-P/SS5-EP clean steam traps have a small built-in drain hole to
ensure no condensate remains in the trap after operation. Therefore, a minimum condensate
load is required during operation to prevent any steam discharge. If the condensate load is less
than the minimum condition, a small amount of live steam will be discharged along with any
condensate.
Parts Inspection
When parts have been removed, or during periodic inspections, use the following table to
inspect the parts and replace any that are found to be defective.
Procedure
Cover Gasket: Check for warping or scratches
Float: Check for warping or scratches
Body: Check for build-up inside the body Check for dirt, oil film, wear or scratches Make sure opening
of the orifice and a drain hole are not plugged with foreign matter
