Inspection And Maintenance - TLV SS3-E Manuel D'utilisation

7. Inspection and Maintenance

Operational inspections should be performed at least twice per year, or as called for by trap
operating conditions. Steam trap failure may result in a temperature drop in the equipment, poor
product quality or losses due to steam leakage.

Wing Nut
• 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 body 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.
Parts Inspection Procedure
Check for warping or damage
Check for scratches, foreign matter, oil film, or liquid inside the float
Check for foreign matter build-up, oil film, scratches and wear
Make sure openings are not plugged with foreign matter

During Reassembly
Tighten wing nut to the proper torque;
open inlet valve and allow live steam to
enter and heat the trap, then close the
inlet valve; after the internal and
atmospheric pressures have equalized
and the trap surface has cooled, tighten
wing nut to the proper torque again.
Steam may leak if wing nut is not re-
tightened.
With gasket in place, align grooves (fig.
A) and gently place the upper body on
the lower body
Replace with a new gasket if damaged
Insert into the body, being careful not to
scratch its polished surface, take care not
to scratch or damage the orifice (fig. B)
