Steam Requirements

Installing Steam Trap and Making Condensate Return Connections

The steam trap must be installed and the coil outlet connections must be connected to the condensate return lines. The following steps outline the procedure for installing the steam trap and connecting the condensate return lines. Refer to Figure 15 for typical installations.

1.Use flexible lines between steam inlet solenoid and steam coils, as well as outlet between steam coil and traps.

2.If necessary, install a strainer at the end of each flexible hose.

3.Install a steam trap to each strainer.

IMPORTANT: Steam trap must be installed a minimum of 18 inches (457 mm) below the steam coil outlet connections.

4.Install a shut-off valve to each steam trap.

5.Connect to the condensate return lines.

6.For steam solenoid valve wiring connections, refer to Wiring Diagram supplied with tumbler.

WARNING

The flexible steam hoses connecting the coil outlet connections and steam traps must have a minimum of 125 psig (pounds per square inch gauge) (8.79 kg/ sq. cm.) working pressure. A shut-off valve must be installed downstream from each steam trap so the condensate return line can be isolated in event a steam trap requires maintenance.

Each steam trap must be supported so minimum load is exerted on the coil outlet connection.
