Steam Requirements 
NOTE: The maximum allowable steam pressure is 
8.6 bar (125 psig). In no case may the pressure 
exceed this value.
Obtain specific steam service pipe sizes from the 
steam system supplier or a qualified steam fitter.
Refer to Figure 2 for proper steam pipe 
configurations.
When tumbler is on the end of a line of 
equipment, extend header at least 1.2 meters 
(4 feet) beyond tumbler. Install shut-off valve, 
union, check valve and bypass trap at end of line. 
If system has a gravity return to the boiler, omit 
trap.
Insulate steam supply and return lines for safety 
of operator and safety while servicing tumbler.
Keep tumbler in good working condition. Repair 
or replace any worn or defective parts.
NOTE: This manual is only a supplement. Refer to 
installation/operation manual for full instructions.
All system components must have a 
8.6 bar (125 psig) 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.
