Normal:
Condensate is discharged continuously with flash steam and the sound of
flow can be heard. If there is very little condensate, there is almost no
sound of flow.
Blocked:
No condensate is discharged. The trap is quiet and makes no noise,
and the surface temperature of the trap is low.
Blowing:
Live steam continually flows from the outlet and there is a continuous
metallic sound.
Live steam is discharged through the trap outlet together with the
condensate and there is a high-pitched sound.
A visual inspection can be carried out to aid in determining the necessity for immediate
maintenance or repair, if the trap is open to atmosphere. If the trap does not discharge to
atmosphere, use diagnostic equipment such as TLV TrapMan or Pocket TrapMan (within their
pressure and temperature measuring range).
(When conducting a visual inspection, flash steam is sometimes mistaken for steam leakage. For
this reason, the use of a steam trap diagnostic instrument such as TLV TrapMan is highly
recommended.)

7.1 Separating/Attaching Trap and Connector Bodies
1. Loosen and remove the connector bolts, remove the entire trap unit from the connector body
and take it to a repair area where it can be supported in a vise during disassembly.
2.A When reinstalling the original trap:
a. Using a small screwdriver, remove the old gaskets from their housings in the trap body,
then clean the housings.
b. New connector gaskets must be installed.
c. To facilitate assembly and prevent loosening of the gaskets, apply a small amount of
suitable adhesive at 120˚ intervals around the outer edge of the gaskets.
d. Holding the trap body so that the gasket housings are horizontal, place the gaskets into
the housings.
2.B When installing a replacement trap:
a. Be sure to remove all protective seals, making sure the connector gaskets are still in place
after having removed their seal.
b. Before installation, scrape the mounting surface of the connector body clean using a soft
tool.
3. Align the bottom edge of the trap body with that of the connector body (see Fig. A below),
making sure the gasket housings on the trap body align with the corresponding recesses in
the connector body. Maintaining the proper alignment, close the tops together until the two
faces are flush, making sure that connector gaskets remain in position.
4. Insert the connector bolts and finger-tighten, keeping trap and connector bodies flush.
Tighten the connector bolts to the proper torque (see p.3).
The S3/S5/S5H trap unit is designed for use
with TLV F46 and F32 connector units and TLV
V1/V2/V1P/V2P Series trap stations. It is not
compatible with TLV F46J connector units.
The connector unit name is indicated on the
connector body.
