Steam Requirements
Obtain specific steam service pipe sizes from the
steam system supplier or a qualified steam fitter.
● Refer to Figure 3 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 the system has a gravity return to 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.
Thermal Oil Prep
It is the responsibility of the customer to install
appropriate coil and heating system for thermal oil
prep models. Alliance Laundry Systems, LLC. is not
responsible for the performance or safety of the
customer installed thermal oil system. To ensure
proper operation, refer to the Specifications and
Dimensions section for the BTU input of equivalent
steam models. Thermal oil systems that do not deliver
appropriate BTUs will dry slower. For solenoid valve
wiring connections, refer to the Wiring Diagram
supplied with tumbler.
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.
