Before you begin please read this manual to ensure correct usage of the product.
Please keep it in a safe place for future reference.
The L Series steam traps L21S, L32S and L21SC, L32SC with check valve can be used without
adjustment for medium capacity applications and pressures up to 2.1, or 3.2 MPaG (300 or 450
psig). These models are suitable for steam-using equipment that discharges condensate at
temperatures slightly below saturation temperature, such as tracer lines and light process equipment.
1 MPa = 10.197 kg/cm2, 1 bar = 0.1 MPa

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.
CAUTION
WARNING
DANGER
CAUTION Indicates that there is a possibility of injury, or equipment/product
damage.
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.
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.
Do not subject the trap 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.
