configurations.  
IMPORTANT: Warranty is void unless tumbler is  
installed according to instructions in this manual.  
Installation should comply with minimum  
specifications and requirements detailed in this  
manual and applicable local gas fitting regulations,  
municipal building codes, water supply regulations,  
electrical wiring regulations, and any other  
relevant statutory regulations. Due to varied  
requirements, applicable local codes should be  
thoroughly understood and all pre-installation

Installation  
A typical tumbler enclosure is shown in Figure 1. Note  
the minimum and maximum dimensions. Local codes  
and ordinances must be complied with.  
Location Requirements  
The tumbler must be installed on a level floor. Floor  
covering materials such as carpeting or tile should be  
removed.  
WARNING  
To reduce the risk of serious injury, install  
lockable door(s) to prevent public access  
to rear of tumblers.  
To assure compliance, consult local building code  
requirements. The tumbler must not be installed or  
stored in area where it will be exposed to water and/or  
weather.  
W055  
IMPORTANT: DO NOT block the airflow at the  
rear of the tumbler with laundry or other articles.  
Doing so would prevent adequate air supply to the  
combustion chamber of the tumbler.  
IMPORTANT: Install tumblers with sufficient  
clearance for servicing and operation, refer to  
Figure 1.  
WARNING  
To reduce the risk of severe injury, clearance of tumbler cabinet from combustible  
construction must conform to the minimum clearances.

W002  
General Information  
This information is to be used when installing gas  
tumblers in countries and/or on gases different than the  
machine’s factory configuration. Tumblers are  
supplied from the factory for operation on Natural Gas  
1000 Btu/cu ft. (8914 kcal/m3), or L.P. Gas 2500 Btu/  
cu ft. (22,250 kcal/m3),in the countries of GB/IE/PT/  
ES/IT/GR/LU/CH. To install machines in any other  
country, or on any other gas, requires some level of  
modification.  
Machines are built in two different configurations:  
Natural Gas – regulated/governor  
Liquefied Petroleum (L.P.) Gas – not regulated/  
no governor  
Machines configured for Natural Gas (regulator/  
governor) may be converted to L.P. Gas (not regulated/  
no governor) with block-open kit, Part No. M400763.  
Serial plates supplied from the factory are configured  
for GB/IE/PT/ES/IT/GR/LU/CH. These instructions  
pertain to the situations when the country of use or gas  
supply is different than that on the serial plate.  
Table 1 describes the different gases that are available  
in different CE countries, and how the machines need  
to be configured to operate with those gases. In the  
CE, there are Natural Gas configurations that do not  
allow for machine regulation and L.P. Gas  
configurations that must be regulated. For L.P. Gas,  
third family B/P at 50 mbar, order Regulated Natural  
Gas machines and convert according to Table 1.

concealed space of a building.  
For maximum efficiency and minimum lint  
accumulation, tumbler air must be exhausted to the  
outdoors by the shortest possible route.  
W059  
Layout  
Proper sized exhaust ducts are essential for proper  
operation. All elbows should be sweep type. Exhaust  
ducts must be assembled so the interior surfaces are  
smooth, so the joints do not permit the accumulation  
of lint. DO NOT use plastic or thin foil flexible ducts.  
Use exhaust ducts made of sheet metal or other  
noncombustible material. Use duct tape or pop-rivets  
on all seams and joints.  
Whenever possible, install tumblers along an outside  
wall where duct length can be kept to a minimum, and  
make-up air can be easily accessed. Construction must  
not block the airflow at the rear of the tumbler. Doing  
so would prevent adequate air supply to the tumbler  
combustion chamber.  
Make-Up Air  
Verify that old ducts are thoroughly cleaned out before  
installing new tumbler(s).  
A tumbler is forced air exhausted and requires provisions  
for make-up air to replace air exhausted by tumbler.  
IMPORTANT: Do not obstruct flow of combustion  
and ventilation air.  
WARNING  
Improperly sized or assembled ductwork  
causes excess back pressure which  
results in slow drying, lint collecting in  
the duct, lint blowing back into the room,

Exhaust Requirements  
Individual Venting  
Manifold Venting  
For maximum efficiency and performance, it is  
preferred to exhaust tumbler(s) individually to the  
outdoors.  
While it is preferable to exhaust tumblers individually  
to the outdoors, a main collector duct may be used if it  
is sized according to Figure 16 and Figure 17. This  
illustration indicates minimum diameters, and should  
be increased if the collector length exceeds 14 feet (4.3  
m) and two 90° elbows. The diameter of a round duct  
must be increased by 10% for each additional 20 feet  
(6.1 m). Cross sectional area of a rectangular or square  
duct must be increased 20% for each additional 20 feet  
(6.1 m). Refer to Table 3 and Table 4 tab to determine  
equivalent ducting sizing. The collector duct may be  
rectangular or square in cross section, as long as the  
area is not reduced. Provisions MUST be made for lint  
removal and cleaning of the collector duct.  
IMPORTANT: At no point may the cross sectional  
area of installed venting be less than the cross  
sectional area of the exhaust outlet of the tumbler.  
The exhaust duct must be designed so the static back  
pressure measured 12 inches (305 mm) from the  
exhaust outlet does not exceed the maximum  
allowable pressure specified on the installation sticker  
on the rear of the tumbler.  
NOTE: Static back pressure must be measured  
with the tumbler running.  
The vent collector system must be designed so the  
static back pressure measured 12 inches (305 mm)  
from the exhaust outlet does not exceed the maximum  
allowable pressure of 0.5 W.C.I. (1.3 mbar) as  
specified on the installation sticker on the rear of  
tumbler. Static back pressure must be measured with  
all tumblers vented into the collector operating.  
The maximum allowable length venting is 14 feet (4.3 m)  
and two 90° elbows or equivalent. If the equivalent  
length of a duct required for an installation exceeds the  
maximum allowable equivalent length, the diameter of  
a round duct must be increased by 10% for each  
additional 20 feet (6.1 m). Cross section area of a  
rectangular duct must be increased by 20% for each  
additional 20 feet (6.1 m). Refer to Table 2 to  
determine equivalent venting.  
NOTE: Never connect a tumbler duct at a 90° angle  
to the collector duct. Refer to Figure 14. Doing so  
will cause excessive back pressure, resulting in poor  
performance. Never connect two tumbler exhaust  
ducts directly across from each other at the point of  
entry to the collector duct.

18 in. (457 mm) One 90° elbow = 21 ft. (6.4 m)  
With the tumbler in operation, airflow at any point  
in the duct should be at least 1200 feet per minute  
(366 m/min.) to ensure that lint remains airborne. If  
1200 feet per minute cannot be maintained,  
schedule monthly inspections and cleaning of the  
ductwork.  
Equivalent Length (feet) = 1.17 x Duct Diameter (inches)

Example: A 12 inch (305 mm) diameter duct’s  
equivalent length of 14 feet (4.3 m) of duct and two

With the tumbler in operation, airflow at any point  
in the duct should be at least 1200 feet per minute  
(366 m/min.) to ensure that lint remains airborne. If  
1200 feet per minute cannot be maintained,  
schedule monthly inspections and cleaning of the  
ductwork.

Gas Requirements  
Obtain specific gas service pipe size from the gas  
supplier. Refer to Table 5 for general pipe size.  
WARNING  
The following must be furnished and installed by the  
customer for the gas service line to each tumbler.  
Refer to Figure 18.  
To reduce the risk of fire or explosion, DO  
NOT CONNECT THE GAS LINE TO THE  
TUMBLER IF THE GAS SERVICE IS NOT  
THE SAME AS THAT SPECIFIED ON THE  
TUMBLER SERIAL PLATE! It will first be  
necessary to convert the gas burner  
orifice and gas valve. Appropriate  
Sediment traps  
Shut-off valves  
Supply pressure taps  
conversion kits are available.  
It is important that equal pressure be maintained at all  
tumbler gas connections. This can be done by  
installing a 1 inch (25.4 mm) pipe gas loop to maintain  
equal pressure at all gas connections. Refer to  
W060  
IMPORTANT: Any product revisions or conversions  
must be made by the Manufacturer’s Authorized  
Dealers, Distributors or local service personnel.  
IMPORTANT: The tumbler must be isolated from  
the gas supply piping system by closing its  
individual manual shut-off valve during any  
pressure testing of the gas supply piping system at  
test pressure equal to or less than 0.5 psig  
(3.45 kPa, 34.5 mbar).  
WARNING  
To reduce the risk of fire or explosion, if  
the tumbler is to be connected to  
Liquefied Petroleum (L.P.) gas, a vent to  
the outdoors must be provided in the  
room where the tumbler is installed.  
IMPORTANT: The tumbler and its manually  
operated appliance gas valve must be disconnected  
from the gas supply piping system during any  
pressure testing of that system at test pressures in  
excess of 0.5 psi (3.45 kPa, 34.5 mbar).

Gas Requirements  
Turn on gas and check all pipe connections (internal  
and external) for gas leaks with a non-corrosive leak  
detection fluid. Purge air in gas service line by  
operating the tumblers in the drying mode. If burner  
does not light and unit goes into lockout, open and  
close the door and restart. Repeat these steps until  
burner ignites. Use pipe compound, resistant to  
actions of L.P. gas, on all pipe threads.

IMPORTANT: Gas loop piping must be installed as illustrated to equalize gas pressure for all tumblers  
connected to single gas service. Other gas using appliances should be connected upstream from loop.

Electrical Requirements  
To Connect Electrical Service To  
The Tumbler  
The following steps outline the procedure for  
connecting the electrical service to the tumbler.  
NOTE: The wiring diagram is located in the  
junction or contactor box.  
1. Install a circuit breaker as close to the tumbler as  
possible. If more than one tumbler is being  
installed, a disconnect switch or circuit breaker  
should be provided for each. This will make it  
possible to disconnect each tumbler for  
maintenance purposes.  
2. Connect the conduit-encased leads to the disconnect  
switch, or circuit breaker. Connect the wire leads  
to the appropriate labeled terminal on the terminal  
block. The ground wire must be connected to the  
ground connection as shown in Figure 21.  
3. Check the electrical service phase sequence  
(three phase only) as follows:  
a. Energize the electrical service (on reversing  
tumblers, ensure nonreversing is selected) and  
momentarily start the tumbler. Check the  
direction of the cylinder rotation. If the  
cylinder rotates clockwise (viewed from the  
front), the phase sequence is correct. If the  
cylinder rotates counterclockwise, proceed  
with step b.  
NOTE:When viewed from the front, the  
fan should rotate clockwise on 50 and 75  
Pound models and counterclockwise on  
F75 models.  
b. Disconnect and reverse any two service leads  
on the terminal block.

Electrical Requirements  
Jumper Configuration Instructions  
Ferrite Ring Installation  
Changing the transformer configuration jumper is  
required, PRIOR TO SUPPLYING POWER TO  
THE MACHINE, if any of the following apply:  
Gas and Steam OPL Control Models Only  
The ferrite ring provided in the literature packet must  
be installed over the power leads during connection of  
electrical service. The ferrite protects the sensitive  
electronic controls from destructive electrical  
disturbances which may be present on power lines to  
the machine. Failure to properly install the ferrite ring  
may result in damage to the electronic controls and  
will void control warranty.  
IMPORTANT: Failure to install the proper  
configuration jumper may result in damage to  
sensitive electronic controls and may void  
warranty.  
You have 200 – 208 Volt service and are  
connecting a model rated for 240 Volt operation.  
To install:  
Replace the 240 Volt jumper with the 208 Volt  
jumper per the conversion label, located on the  
rear of the tumbler, sign and date conversion  
label to document the conversion.  
1. Immediately after connection of power leads and  
before applying power to machine, locate each of  
the incoming service leads including ground.  
2. Snap the ferrite ring closed over all the service  
leads inside of the contactor box as shown. It is  
important that the ferrite ring be installed inside  
the contactor box. Refer to Figure 22. Do not  
install the ferrite outside of the box or other area.  
Make sure that service leads are in the center of  
the ferrite before closing the ring so as not to  
pinch or damage leads.  
You have 400 – 415 Volt service and are  
connecting a model rated for 380 Volt operation.  
NOTE: CE electro-mechanical timer models (MT,  
RT and CD control suffixes) do NOT require  
conversion jumper.  
Replace the 380 Volt jumper with the 415 Volt jumper  
per the conversion label, located on the rear of the  
tumbler, sign and date conversion label to document  
the conversion.

Steam Requirements  
NOTE: Machines require a constant 80 to 100 psig  
Install vacuum breaker (optional), bucket trap  
(5.62 to 7.03 kg/sq cm) steam service for optimum  
operation. The maximum allowable steam pressure  
for use with 60 Hertz or 50 Hertz tumblers is  
125 psig (8.6 bar). In no case may the pressure  
exceed the above value.  
with built-in strainer and check valve. For  
successful operation of tumbler, install trap  
18 inches (457 mm) below coil and as near to the  
tumbler as possible. Inspect trap carefully for  
inlet and outlet markings and install according to  
trap manufacturer's instructions. If steam is  
gravity returned to boiler, omit trap but install  
vacuum breaker and check valve in return line  
near tumbler. Gravity return requires entire return  
plumbing be below steam coil outlets.  
Obtain specific steam service pipe sizes from steam  
system supplier or a qualified steam fitter.  
Refer to Figure 23 for proper steam pipe  
configurations.  
Install union and shut-off valve in return line and  
make final pipe connections to return header.  
To prevent condensate draining from headers to  
tumbler, piping should have a minimum 12 inch  
(305 mm) rise above respective header. Do not  
make steam connection to header with a  
NOTE: To prevent water hammering, route return  
lines below outlets of steam coils.  
horizontal or downward facing tee or elbow.  
Whenever possible, horizontal runs of steam  
lines must drain, by gravity, to respective steam  
header. Water pockets, or an improperly drained  
steam header will provide wet steam, causing  
improper operation of tumbler. If pockets or  
improper drainage cannot be eliminated, install a  
bypass trap to drain condensate from the low  
point in the steam header to the return.  
In both steam supply and steam return line, it is  
recommended that each have a pipe union and  
shut-off valve. This will enable you to disconnect  
the steam connections and service the tumbler  
while your laundry facility is in operation.  
Connect the steam solenoid valve to the related  
steam coil inlet connection with nipples, flex  
hoses, unions and tees.  
Strainers may require cleaning due to materials  
from hoses or pipes.

Steam Requirements  
Piping Recommendations  
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.  
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.  
Each steam trap must be supported so  
minimum load is exerted on the coil outlet  
connection.  
W066  
WARNING  
Thermal Oil Prep  
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.  
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 components (solenoid valve, traps)  
must be supported to minimize loads on  
the tumbler steam coil connections.  
W480R2  
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.

Single Drop Timer  
NOTE: The following information is for  
Setting Dry Time Dipswitches  
models with an SD control suffix only.  
To change the dry time on the tumbler, combinations  
of dipswitches can be set on the control.  
Power-Up Mode  
There are eight dipswitches on the tumbler control.  
The first six switches are used to program the amount  
of additional heat time given for each coin pulse. The  
additional drying time is added to the factory default  
minimum heat time of one minute. A valve of 1 to 64  
minutes of additional drying time is available for each  
coin drop pulse.  
When power is applied to the tumbler, the IN USE  
light flashes factory status information. Following this,  
the control goes into READY Mode (light off) or RUN  
Mode if power was interrupted during a cycle (light  
on, time remaining unchanged).  
Ready Mode  
The last two switches are used to program the amount  
of additional cool down time. The additional cool  
down time is added to the factory default minimum  
cool down time of 1 minute. A value of 1 to 3  
additional minutes is available. The control is shipped  
from the factory programmed with 1 minute of  
minimum heat time, preset with 7 additional minutes  
of drying time (dipswitches 1, 2 and 3 in ON position)  
and 1 minute of minimum cool down time for a total  
time of 9 minutes for a coin pulse. For dipswitch  
settings Refer to Table 12.  
In READY Mode (light off), the control waits for the  
vend to be satisfied. When vend is satisfied the control  
goes into START Mode.  
Start Mode  
In START Mode (light on), the vend has been satisfied  
but the start button has not been pressed. Time  
remaining in the cycle will not change until the start  
button is pressed. When the start button is pressed the  
machine goes into RUN Mode.  
The control reads the dipswitch settings at power-up.  
The control must be powered down to change the  
dipswitch settings.  
Run Mode  
In RUN Mode (light on), the machine is running a  
cycle and the time remaining is counting down. When  
time remaining counts down to zero, the control goes  
into READY Mode.  
To change the time for a coin pulse, the desired dry  
time dipswitches must be set to ON position. All other  
dipswitches must be in OFF position.

5. After air shutter is adjusted for proper flame,  
tighten air shutter adjusting screw securely.  
WARNING  
To reduce the risk of electric shock, fire,  
explosion, serious injury or death:  
• Disconnect electric power to the  
tumbler before servicing.  
PROPER AIRFLOW  
• Close gas shut-off valve to gas tumbler  
before servicing.  
• Close steam valve to steam tumbler  
before servicing.  
• Never start the tumbler with any guards/  
panels removed.  
• Whenever ground wires are removed  
during servicing, these ground wires  
must be reconnected to ensure that the  
1
tumbler is properly grounded.

Gas Burner Air Shutter  
INSUFFICIENT AIRFLOW  
NOTE: Air inlet shutters on the burner must be  
adjusted so sufficient air is metered into the system  
for proper combustion and maximum efficiency.  
Before adjusting the inlet shutters be sure that all  
lint is removed from lint compartments and lint  
screen.  
Air shutter adjustments will vary from location to  
location and will depend on the vent system, number  
of units installed, make-up air and line gas pressure.  
Opening the shutter increases the amount of primary  
air supplied to the burner while closing the shutter  
decreases the primary air supply. Adjust air shutter as  
follows:  
1
Refer to Figure 25.  
NO AIRFLOW  
1. Open the access panel.  
2. Start the tumbler and check the flame pattern. If  
the flame pattern is straight up, insufficient air is  
flowing through the tumbler and airflow switch is  
improperly set. A flame pattern that flares to the  
right and left indicates no air is flowing through  
the tumbler. Correct air and gas mixture is  
indicated if the flame pattern is primarily blue,  
with small yellow tips, and bends to the right of  
the heater section. Too little air is indicated if the  
flame if yellow, lazy and smokey.

Adjustments  
The airflow switch operation is controlled by the  
Airflow Switch  
counterweight position in the shaft. Moving the  
counterweight either increases or decreases airflow  
switch sensitivity. The counterweight should be  
adjusted so the disc moves away from the cabinet when  
the lint panel is opened 1.5 inches (38.1 mm) with a full  
load. Adjust the airflow switch as follows:  
Gas and Electric Tumblers  
WARNING  
To reduce the risk of fire due to  
inadequate airflow, the airflow switch  
must be adjusted to operate per the  
instructions in this manual.  
1. Load the tumbler. This adjustment is much faster  
to make with one person opening lint panel in  
front and another adjusting the counterweight in  
the rear of tumbler.  
W674  
The airflow switch (located on the rear of tumbler,  
Figure 26) is set at the factory for proper operation.  
However, if there is a problem with the switch, it  
should be adjusted as follows:  
2. Temporarily tape down the lint panel safety  
switch located behind the upper right corner of  
the lint panel.  
3. Start the tumbler. Open the lint panel 1.5 inches  
(38.1 mm). The airflow disc should move away  
from the cabinet, opening the switch contacts and  
shutting off the heat system. This indicates  
proper operation and proper adjustment.  
Confirm exhaust duct and make-up air vents are  
properly sized and not obstructed. Refer to  
Make-Up Air and Venting sections.  
Confirm lint screen is clean and access panels are  
in place.  
4. If switch is not opening as described in step 3, it  
should be adjusted so it is MORE sensitive.  
Depress the spring clip and move counterweight  
toward disc. Retest by opening lint panel and  
continue moving counterweight toward disc until  
switch operates as described in step 3.  
Check operation of airflow switch and adjust as  
follows:  
NOTE: Steam models do not have an airflow  
switch.  
5. If switch opens BEFORE lint panel is opened the  
proper distance, step 3, it should be adjusted so it  
is LESS sensitive. Depress the spring clip and  
move counterweight away from the disc. Retest  
by opening lint panel and continue moving  
counterweight away from disc until switch  
operates as described in step 3.  
IMPORTANT: Remove tape from lint panel switch.
