Piping Recommendations
• Trap each steam coil individually. Always keep the trap
clean and in good working condition.
• When tumble dryer is on the end of a line of equipment,
extend header at least 4 feet (1.2 m) beyond tumble dryer.
Install shut-off valve, union, check valve and bypass trap at
end of line. If gravity return to boiler, omit trap.
• Insulate steam supply and return lines for safety of operator
and safety while servicing tumble dryer.
WARNING
All system components must have a 125 psig
(8.6 bar) working pressure. Shut-off valves must
be installed upstream of the steam solenoid valve
and downstream of each steam trap so components
can be isolated for maintenance or emergency
purposes. All components (solenoid valve, traps)
must be supported to minimize loads on the tumbler
steam coil connections.

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 27 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 tumble dryer.
