6. Start-up Procedure
IMPORTANT START-UP PROCEDURE
To ensure proper operation, slowly open the inlet valve slightly. Initially
OPEN THE VALVE ONLY
1/32 TURN
in order to supply steam to the trap very slowly, then
WAIT FOR AT LEAST 30
SECONDS
for air to vent before fully opening the inlet valve.
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 Pocket TrapMan (within its
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.)
Normal:
Condensate is discharged in a short blast followed by a longer period of no
drainage. During the discharge, flash steam may be seen. A small amount of flash
steam may be visible after the discharge.
Blocked:
(Discharge
Impossible) No condensate is discharged. The trap is quiet and makes no noise. 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: Live steam is discharged through the trap outlet together with condensate,
accompanied by a high-pitched sound.
Chattering: The trap does not close properly. Steam is discharged from the trap in short rapid
bursts.
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.
8. Inspection and Maintenance
• Installation, inspection, maintenance, repairs, disassembly, adjustment and
valve opening/closing should be carried out only by trained maintenance
personnel.
• Before attempting to open 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.
• Be sure to use the proper components and NEVER attempt to modify the product.
