Inspection And Maintenance - Tlv Ja3 Manuel D'utilisation

Normal:
Condensate is discharged continuously and the sound of flow like that of water
draining from a bathtub can be heard. With very little condensate, there is almost
no sound of flow.
Blocked: No condensate is discharged. The trap is quiet and makes no noise The surface
temperature of the trap is low.
Blowing: Air continually flows from the outlet and there is a continuous sound of a forceful
stream against a surface.
Air Leakage: Air is discharged through the trap outlet together with the condensate and there is
a hissing sound.
If the trap shows signs of blockage, blowing or air leakage, perform manual blowdown by pushing
the plunger in several times with a fingertip to allow dirt and oil to be discharged through the
orifice. If this does not remedy the problem, follow the instructions under chapter 8,
"Troubleshooting".

7. Inspection and Maintenance

Periodic operational inspections should be performed at least biannually or at intervals
according to use. Faulty air traps may result in losses due to air leakage.
WARNING
CAUTION
• Before attempting to open the trap, close the inlet and outlet isolating valves, and the valve in the
equalizing pipe and wait until the trap has cooled to room temperature. Reduce the internal
pressure to atmospheric pressure by slowly and cautiously turning the drain plug a few degrees
so that condensate and air can escape. Then open the drain plug completely to drain the
condensate from inside the body. Failure to do so may result in burns or injuries.
• Be sure to use the proper components and NEVER try to modify the product.

*Option
NEVER apply direct heat to the float. The float may explode due to
increased internal pressure, causing accidents leading to serious injury or
property and equipment damage.
• Installation, inspection, maintenance, repairs, disassembly, adjustment and
valve opening/closing should be done only by trained maintenance
personnel.
