7. Inspection and Maintenance
• Installation, inspection, maintenance, repairs, disassembly, adjustment
and valve opening/closing should be carried out only by trained
maintenance personnel.
• Before removing the trap body from the connector body, close the inlet
and outlet isolation valves and wait until the entire unit has cooled
completely. Failure to do so may result in burns.
• Be sure to use the proper components and NEVER attempt to modify the
product.
CAUTION
Operational inspections should be performed at least twice per year, or as called for by trap
operating conditions. Steam trap failure may result in temperature drop in the equipment, poor
product quality or losses due to steam leakage.
While the trap body itself is maintenance-free, there may be other causes of malfunction, as
described in the “Troubleshooting” and “Piping Arrangement” chapters. If the corrective
measures described therein do not solve the problem, it is possible that the trap has reached the
end of its service life and requires replacement.
6. Piping Arrangement
1. Is the pipe diameter suitable?
2. Has the trap unit been installed within the allowable inclination and with the arrow on the
body pointing in the direction of flow?
3. Has sufficient space been secured for maintenance?
4. Have maintenance valves been installed at the inlet and outlet? If the outlet is subject
to back pressure, has a check valve been installed?
5. 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?
6. Has the piping work been done correctly, as shown in the table below?
Check to make sure that the pipes connected to the trap have been installed properly.
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.
Correct
Incorrect
Diameter is too
small.
Rust and scale
flow into the trap
with the
condensate.
Condensate
collects
in the pipe.
Diameter is too
small and inlet
protrudes into pipe.
