Introduction
Before you begin, please read this manual to ensure correct usage of the product, and keep it in
a safe place for future reference.
The JX Series steam traps with thermostatic air vent (X-element) are suitable for a wide range of
applications up to 2.1 MPaG (300 psig), such as tracer lines, unit and process heaters, heating
coils, heat exchangers, etc. The traps discharge condensate continuously and automatically, at a
temperature slightly lower than saturation temperature.
1 MPa = 10.197 kg/cm
2
, 1 bar = 0.1 MPa
For products with special specifications or with options not included in this manual, contact TLV
for instructions.

1. 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.
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.
WARNING
CAUTION
WARNING
DANGER CAUTION
Indicates that there is a
possibility of injury or equip-
ment/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, which 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.
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.
DO NOT use this product in excess of the maximum operating
pressure differential. Such use could make discharge impossible.
DO NOT subject this product to condensate loads that exceed its
dischargecapacity. Failure to observe this precaution may lead to
condensate accumulation upstream of the trap, resulting in reduced
equipment performance or damage to the equipment.

CAUTION
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
or burns or other injury due to malfunction or the discharge of fluids.
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 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.
Do not use excessive force when connecting threaded pipes to the
product. Overtightening may cause breakage leading to fluid discharge,
which may cause burns or other injury.
2. Specifications
To avoid malfunctions, product damage, accidents or serious injury, install
properly and DO NOT use this product outside the specification range. Local
regulations may restrict the use of this product to below the conditions quoted.
