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 that poses a threat of death or serious injury.
Indicates a DANGER, WARNING or CAUTION item.
Indicates that there is a potential threat of death or serious injury.
WARNING
DANGER
CAUTION
Indicates that there is a possibility of injury, or equipment/product
damage.
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, 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.
DO NOT subject this product to condensate loads that exceed its
discharge capacity. Failure to observe this precaution may lead to
condensate accumulation upstream of the trap, resulting in reduced
equipment performance or damage to the equipment.

Introduction
Before beginning installation or maintenance, please read this manual to ensure correct use of the
product. Keep the manual in a safe place for future reference.
The A3N·AF3N steam trap can be used without adjustment for medium capacity applications
between 0.03 and 1.6 MPaG* (4 and 230 psig). This model is suitable for steam equipment
that discharges condensate at temperatures slightly below saturation temperature, as
well as for discharging condensate from steam mains, branch pipes, tracing, etc.
* For DIN, 13 barg
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.

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.
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.
