Inspection And Maintenance - TLV SH Série Manuel D'utilisation

6. 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.
WARNING
CAUTION
• Before attempting to open the trap, close the inlet and outlet isolation 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.

and valve opening/closing should be carried out only by trained
maintenance personnel.
