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.
7. Inspection and Maintenance
WARNING
• 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 carried out only by trained maintenance personnel.
• 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.
