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 FS3/FS5/FS5H steam traps (trap units S3/S5/S5H and connector unit F46 or former
connector unit F32*), designed for installation in any inclination, are suitable for small and medium
capacity applications between 0.01 and 4.6 MPaG (1 and 650 psig); such as saturated and
superheated steam mains, branches, tracer lines and small-to-medium size process equipment.
The traps discharge condensate continuously and automatically at a temperature slightly lower
than saturation temperature.
* Configuration of F32 differs slightly from that of F46
1 MPa = 10.197 kg/cm
2
, 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.

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.
DO NOT use this product in excess of the maximum operating pressure
differential. Such use could make discharge impossible (blocked).
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.
