Steam Requirements

Piping Recommendations

Trap each steam coil individually. Always keep
G
the trap clean and in good working condition.
When tumbler is on the end of a line of
G
equipment, extend header at least 4 feet
(1.2 meters) beyond tumbler. 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 line for safety of
G
operator and safety while servicing tumbler.
Keep tumbler in good working condition. Repair
G
or replace any worn or defective parts.
NOTE: Steam heated tumbler models are not
certified by the American Gas Association or the
Canadian Gas Association.
High pressure machines require a (constant)
80-100 psig (pounds per square inch gauge)
2
(5.62-7.03 kg/cm ) steam service for optimum
operation.
WARNING
All system components must have a
125 psig (10 bar) working pressure.
Shut-off gate 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

return lines. The following steps outline the procedure
for installing the steam trap and connecting the
condensate return lines. Refer to Figure 16 and
Figure 17 for typical installations.
1. Connect a flexible hose to each steam coil outlet.
2. Install a strainer to the ends of each flexible hose.
3. Install a steam trap to each strainer.
IMPORTANT: Steam trap must be installed a
minimum of 10 inches (254 mm) below the steam
coil outlet connections.
4. Install a globe shut-off valve to each steam trap.
