damage are evident, have the carrier note the condition  
on the shipping papers before the shipping receipt is  
signed, or advise the carrier of the condition as soon as  
it is discovered.  
The tumbler must be installed on a level floor. Floor  
covering materials such as carpeting or tile should be  
removed.  
To assure compliance, consult local building code  
requirements. The tumbler must not be installed or  
stored in an area where it will be exposed to water  
and/or weather.  
Remove the crate and protective cover as soon as  
possible and check the items listed on the packing list.  
Advise the carrier of any damaged or missing articles  
as soon as possible. A written claim should be filed  
with the carrier immediately if articles are damaged or  
missing.  
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.  
A typical tumbler enclosure is shown in Figure 1. Note  
that the enclosure touches the tumbler top and side  
panels. Also, note the minimum and maximum  
dimensions. Local codes and ordinances must be  
complied with.  
IMPORTANT: Warranty is void unless tumbler is  
installed according to instructions in this manual.  
Installation should comply with minimum  
specifications and requirements detailed herein,  
and with 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  
work arranged for accordingly.  
WARNING  
To reduce the risk of serious injury, install  
lockable door(s) to prevent public access to

Installation  
Table 3 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 3.  
WARNING  
When converting the tumbler to a  
different gas or pressure, first verify that  
the supply inlet pressure is equipped with  
a pressure regulator (located ahead of the  
tumbler) that will maintain the gas supply  
at the inlet pressure specified.  
W430  
Basic Configuration  
1. Determine the necessary conversion operations to  
convert from the factory-supplied configuration  
to the desired configuration.

Exhaust Requirements  
Venting  
WARNING  
For maximum efficiency and minimum lint  
accumulation, tumbler air must be exhausted to the  
outdoors by the shortest possible route.  
A drying tumbler produces combustible  
lint. To reduce the risk of fire, the tumbler  
must be exhausted to the outdoors.  
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 non-  
combustible material. Use duct tape or pop-rivets on  
all seams and joints.  
W057  
To reduce the risk of fire and  
accumulation of combustible gases, DO  
NOT exhaust tumbler air into a window  
well, gas vent, chimney or enclosed,  
unventilated area such as an attic wall,  
ceiling, crawl space under a building, or  
concealed space of a building.  
W059  
Verify that old ducts are thoroughly cleaned out before  
installing new tumbler(s).  
Layout  
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. Elbows and long  
vents tend to increase drying time. Construction must  
not block the airflow at the rear of the tumbler. Doing  
so would prevent adequate air supply to the tumbler’s  
combustion chamber.  
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,  
and increased fire hazard.  
W355  
Make-Up Air  
NOTE: Exhaust ducts must be constructed of sheet  
metal or other noncombustible material. Such  
ducts must be equivalent in strength and corrosion  
resistance to ducts made of galvanized sheet steel  
not less than 0.0195 inches (0.495 mm) thick. Local  
codes may require additional thickness.  
A tumbler is forced air exhausted and requires provisions  
for make-up air to replace air exhausted by the tumbler.  
IMPORTANT: Do not obstruct the flow of  
combustion and ventilation air.  
Make-up air openings should be as close to the  
tumbler(s) as possible.  
Where the exhaust duct pierces a combustible wall or  
ceiling the opening must be sized per local codes. The  
space around the duct may be sealed with  
The required make-up air opening to the outside for  
each tumbler (includes both pockets) is:  
220 square inches (1418 sq. cm) for T30 models  
288 square inches (1856 sq. cm) for T45 models  
IMPORTANT: For best performance provide an  
individual exhaust duct for each tumbler. Do not  
install a hot water heater in a room containing  
tumblers. It is better to have the water heater in a  
separate room with a separate air inlet.  
Make-up air openings with louvers will restrict  
airflow. The opening must be increased to compensate  
for area taken up by louvers.  
Make-up air openings for a room containing  
tumbler(s) and/or gas fired hot water heater or other  
gravity vented appliances must be increased  
sufficiently to prevent downdrafts in any of the vents  
when all tumblers are in operation. Do not locate  
gravity vented appliances in the same room as  
tumblers. If it is necessary to duct make-up air to the  
tumbler(s), increase the area of the ductwork by 25%  
to compensate for any restriction in air movement.

One 90° elbow = 16 ft. (4.9 m)  
One 90° elbow = 18.7 ft. (5.7 m)  
One 90° elbow = 21 ft. (6.4 m)  
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.  
Equivalent Length (feet) = 1.17 x Duct Diameter (inches)  
Table 4  
Example: A 12 inch (305 mm) diameter duct’s  
equivalent length of 14 feet (4.3 m) of duct and two  
90° elbows is:  
NOTE: Static back pressure must be measured  
with both pockets running.  
Equivalent Length = 14 feet + (2) 90° elbows  
= 14 feet + 14 feet + 14 feet  
The maximum allowable length venting of the same  
diameter as the exhaust thimble 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 4 to determine equivalent venting.  
= 42 feet (12.8 m)  
With the tumbler in operation, and both pockets  
running, airflow at any point in the duct should be at  
least 1200 feet per minute (366 meters per meter) to  
ensure that lint remains airborne. If 1200 feet per

Exhaust Requirements  
NOTE: Never connect a tumbler duct at a 90° angle  
to the collector duct. Refer to Figure 10. 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.  
Manifold Venting  
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 11. 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 5 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.  
With the tumbler in operation, and both pockets  
running, airflow at any point in the duct should be at  
least 1200 feet per minute (366 meters per meter) to  
ensure that lint remains airborne. If 1200 feet per  
minute cannot be maintained, schedule monthly  
inspections and cleaning of the ductwork.  
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 specified on the installation sticker  
on the rear of tumbler. Static back pressure must be  
measured with all tumblers vented into the collector  
operating.

Gas Requirements  
The following must be furnished and installed by the  
customer for the gas service line to each tumbler.  
Refer to Figure 12.  
WARNING  
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  
It is important that equal pressure be maintained at all  
tumbler gas connections. This can best be done by  
installing a one inch (25 mm) pipe gas loop. Refer to  
conversion kits are available.  
W060  
IMPORTANT: Any product revisions or conversions  
must be made by the Manufacturer’s Authorized  
Dealers, Distributors or local service personnel.  
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 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).  
W062  
NATURAL GAS line pressure must be maintained at  
6.5 water column inches (1.62 kPa) with no less than 5  
water column inches (1.24 kPa) and no more than 10.5  
water column inches (2.61 kPa), with all gas  
appliances running (tumblers, water heaters, space  
heaters, furnace, etc.). An in-line pressure regulator  
may be required if the line pressure exceeds 8 water  
column inches (2.0 kPa) with all gas appliances  
running.  
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).  
IMPORTANT: The installation must comply with  
local codes or, in the absence of local codes:  
LIQUID PETROLEUM GAS (L.P.) line pressure must  
be maintained at 11 water column inches (2.74 kPa),  
with no less than 10 water column inches (2.49 kPa)  
and no more than 13 water column inches (3.23 kPa),  
with all gas appliances running (tumblers, water  
heaters, space heaters, furnace, etc.).

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.

Electrical Requirements  
If tumbler requires conversion for use on another  
service voltage, complete the steps detailed in the  
Conversion Instructions section prior to connecting  
service to machine.  
Connecting Electrical Service  
The following steps outline the procedure for  
connecting electrical service to the tumbler.  
3 Phase models – Each tumbler must be  
connected to its own individual branch circuit  
breaker, not fuses, to avoid the possibility of  
“single phasing” and causing premature  
failure of the motor(s).  
If tumbler does not require conversion or has been  
converted according to the Conversion Instructions  
section of this manual, continue with step 1.  
NOTE: The wiring diagram is located in the upper  
junction box or upper contactor box.  
Electrical service must be connected using the  
appropriate permanent rigid metal conduit  
system.  
1. For new service, install a circuit breaker or fused  
disconnect of proper voltage and current rating as  
close to each tumbler as possible.  
Service conductors must be copper only.  
2. Route service conduit from circuit breaker panel  
or disconnect panel to tumbler service connection  
box. Conduit routing should not obstruct access  
for maintenance or servicing. Refer to Service/  
Ground Location.  
For an existing service, determine your service voltage  
and conductor amperage. Carefully review the tumbler  
serial plate ratings and Electrical Requirements  
section of this manual. If service is inadequate it must  
be upgraded by a qualified electrical contractor. Never  
connect an improper or inadequate service to any  
machine.  
3. Pull conductors through conduit and attach to  
circuit breaker and ground connection. Secure  
service ground wire to the grounding screw or  
lug. Attach service conductors to appropriately  
labeled positions on the terminal block. Make  
sure all connections are secure.  
Configuring Your Tumbler for Other  
Service Voltages  
Several gas and steam tumbler models have been  
designed to be field convertible to other service  
voltages. Refer to Table 8 for these models:  
4. Check electrical service phase sequence (3 Phase  
models only) as follows:  
a. Energize the electrical service and

Steam Requirements  
NOTE: Machines require a constant 80 to 100 psig  
NOTE: To prevent water hammering, route return  
lines below outlets of steam coils.  
(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.  
Piping Recommendations  
Trap each steam coil individually. Always keep  
the trap clean and in good working condition.  
Obtain specific steam service pipe sizes from the  
steam system supplier or a qualified steam fitter.  
When tumbler is on the end of a line of  
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.  
Refer to Figure 14 for proper steam pipe  
configurations.  
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  
Insulate steam supply and return line for safety of  
operator and safety while servicing tumbler.  
Keep tumbler in good working condition. Repair  
horizontal or downward facing tee or elbow.  
or replace any worn or defective parts.  
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.  
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  
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.  
maintenance or emergency purposes.  
All components (solenoid valve, traps)  
must be supported to minimize loads on  
the tumbler steam coil connections.  
W480R2  
Connect the steam solenoid valve to the related  
steam coil inlet connection with nipples, flex  
hoses, unions and tee.  
Strainers may require cleaning due to materials  
from hoses or pipes.  
Install vacuum breaker (optional), bucket trap  
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  
optional vacuum breaker and check valve in  
return line near tumbler. Gravity return requires  
entire return plumbing be below steam coil  
outlet.  
Install union and shut-off valve in return line and  
make final pipe connections to return header.

Steam Requirements  
Installing Steam Trap and Making  
Condensate Return 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.  
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 14 for typical  
installations.  
1. Use flexible lines between steam inlet solenoid  
and steam coils, as well as outlet between steam  
coil and traps.  
Each steam trap must be supported so  
minimum load is exerted on the coil outlet  
2. If necessary, install a strainer at the end of each  
flexible hose.  
connection.  
W066  
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 13.  
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.

Adjustments  
Loading Door Switch  
Airflow Switch  
The door switch should be adjusted so the cylinder  
stops when door is opened 2 inches (51 mm) plus or  
minus 0.25 inch (6 mm). This switch is a normally  
open switch and is closed by the hinge cam when the  
door is closed. If adjustment is required, refer to  
Figure 15 and proceed as follows:  
The airflow switch is set at the factory for proper  
operation. No adjustment necessary.  
The airflow switch operation may be affected by  
shipping tape still in place, lack of make-up air, or an  
obstruction in the exhaust duct. These should be  
checked and the required corrective action taken.  
1. Close door and start tumbler, slowly open loading  
door. Cylinder and heat system should shut off  
when door is open 2 inches (51 mm) plus or  
minus 0.25 inch (6 mm).  
WARNING  
The tumbler must not be operated if the  
airflow switch does not operate properly.  
Faulty airflow switch operation may cause  
an explosive gas mixture to collect in the  
2. Slowly close the loading door. When door is  
2 inches (51 mm) from being fully closed, the  
door switch actuating bracket (located on the  
door) should depress the button and the switch  
arm with an audible “click.”  
tumbler.  
W072  
3. If the actuating bracket does not operate the  
switch at the appropriate door closure, bend the  
actuating switch bracket in or out to achieve  
proper actuation.  
IMPORTANT: Airflow switch vane must remain  
closed during operation. If it opens and closes  
during the drying cycle, this indicates insufficient  
airflow through the tumbler. If switch remains  
open, or pops open and closed during the cycle, the  
heating system will shut off. The cylinder and fan  
will continue to operate even though the airflow  
switch is indicating insufficient airflow.  
NOTE: To properly mount the airflow switch  
bracket, or in case of a load not drying, the airflow  
switch bracket may need to be checked for proper  
alignment. Be sure the locator pins are securely in  
their respective holes before tightening the bracket  
mounting screws. This will assure proper  
alignment of the airflow switch arm in the channel  
of the airflow switch bracket and prevent binding  
of the arm.

Adjustments  
Door Strike  
The door strike must be adjusted to have sufficient  
tension to hold loading door closed against force of the  
load tumbling against it. There is proper adjustment of  
pull force when 8 to 15 pounds (35.6 N – 66.7 N) is  
required to open door.  
If adjustment is required, refer to Figure 16 and  
proceed as follows:  
To adjust, open door, loosen acorn nut, and turn door  
strike screw in or out as required. Retighten acorn nut.
