8. Inspection and Maintenance

operating conditions. Steam trap failure may result in temperature drop in the equipment, poor
product quality or losses due to steam leakage.

trained maintenance personnel.
• Before attempting to open the trap, close the inlet and outlet isolating

result in burns.
• Be sure to use the proper components and NEVER attempt to modify the
product.
