1. Is the pipe diameter suitable?
2. Has the trap been installed within the allowable inclination and with the arrow on the body
pointing in the direction of flow?
3. Has sufficient space been secured for maintenance?
4. Have maintenance valves been installed at the inlet and outlet? If the outlet is subject to
back pressure, has a check valve been installed?
5. Is the inlet pipe as short as possible, with as few bends as possible, and installed so that the
condensate will flow naturally down into the trap?
6. Has the piping work been done with the proper methods, as shown in the table on page 8?
Check to make sure that the pipes connected to the trap have been installed properly.
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.
6. 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.
