4. Proper Installation
●
CAUTION
NOTE: For socket weld connections, use electric arc welding with a single pass. Internal parts
are not damaged by one-pass welding.
1. Before installation, be sure to remove all protective seals.
2. Before installing the trap, blow out the inlet piping to remove all dirt and oil.
3. Install a bypass valve to discharge condensate, and inlet and outlet valves to isolate the trap
in the event of trap failure or when carrying out maintenance.
4. Install the trap in the lowest part of the pipeline or equipment so the condensate flows
naturally downward into the trap by gravity. The inlet pipe should be as short and have as
few bends as possible.
5. Install the trap within the allowable inclination, as shown below, with the arrow on the
nameplate pointing in the direction of flow.
6. Make sure the “UP” sticker on the vertical type, or the name plate on the horizontal type is
facing up.
7. Install a check valve at the trap outlet whenever the condensate discharge pipe leads to a
tank or recovery line, or whenever the condensate collection pipeline is connected to more
than one trap.
8. When completing the piping, support the pipes within 0.8 meters (2.5 ft.) on either side of
the trap.
9. The use of unions is recommended to facilitate connection and disconnection of the
screwed versions.
Installation, inspection, maintenance, repairs, disassembly, adjustment
and valve opening/closing should be carried out only by trained
maintenance personnel.

5. Piping Arrangement
Check to make sure that the pipes connected to the trap have been installed properly.
1. Has the piping work been done with the proper methods, as shown in the table below?
Requirement
Install a catchpot with the
proper diameter.
Make sure the flow of
condensate is not
obstructed.
To prevent rust and scale
from flowing into the trap,
connect the inlet pipe
25 - 50 mm (1 - 2 in) above
the base of the T - pipe.
When installing on the
blind end, make sure
nothing obstructs the flow
of condensate.
2. Is the pipe diameter suitable?
3. Has the trap been installed within the allowable inclination, with name plate or UP seal facing
up and with the arrow on the nameplate pointing in the direction of flow?
4. Has sufficient space been secured for maintenance?
5. Have maintenance valves been installed at the inlet and outlet? If the outlet is subject to
back pressure, has a check valve been installed?
6. Is the inlet pipe as short as possible, with as few bends as possible, and installed so that the
condensate will flow naturally down into the trap?
Correct
Incorrect
Diameter is too
small.
Diameter is too
small and inlet
protrudes into pipe.
Rust and scale
flow into the trap
with the
condensate.
Condensate
collects in the
pipe.
6. Inspection and Maintenance
CAUTION
Periodic operational inspections should be performed, at least twice per year or at intervals
according to use. Steam trap failure may result in temperature drop in the equipment, poor
product quality or increased losses due to steam leakage.
While the trap itself is maintenance-free, there may be other causes of malfunction, as
described in chapter 5 "Piping Arrangement" and chapter 7 "Troubleshooting". If the
corrective measures described therein do not solve the problem, the trap has possibly reached
the end of its service life and must be replaced.
Installation, inspection, maintenance, repairs, disassembly, adjustment
and valve opening/closing should be carried out only by trained
maintenance personnel.
Before attempting removal of the trap, close the inlet and outlet isolating
valves and wait until the trap has cooled completely. Failure to do so may
result in burns.
7. Troubleshooting
If the expected performance is unachievable after installation of the steam trap, read chapters 4
and 5 again and check the following points for appropriate corrective measures.

8. Operational Check
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 its
pressure and temperature measurement range).
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.
Steam
Leakage:
(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.)
Live steam is discharged through the trap outlet together with the
condensate and there is a high-pitched sound.
