Piping Recommendations
Trap each steam coil individually. Always keep 
the trap clean and in good working condition.
When tumbler is on the end of a line of 
equipment, extend header at least 4 feet (1.2 m) 
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 lines for safety 
of operator and safety while servicing tumbler.
Keep tumbler in good working condition. Repair 
or replace any worn or defective parts.
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 23 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.
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.
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.

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.
