Operational Check - TLV LV Série Manuel D'utilisation

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.

7. 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 TLV Pocket TrapMan (within
their pressure and temperature measurement range).
Normal:
Blocked:
(Discharge Impossible)
Blowing:
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.)
Flash Steam
White jet
containing
water droplets
Correct
Condensate is discharged intermittently with flash steam and the
sound of flow can be heard.
No condensate is discharged. The trap is quiet and makes no noise.
The surface temperature of the trap is low.
Live steam continually flows from the outlet and there may be a high-
pitched whistling sound.
Live steam is discharged through the trap outlet together with the
condensate and there may be a high-pitched whistling sound.
