Remove four nuts from the literature package, and
screw one fully on to each leveling leg.
Screw the four leveling legs (bolts) back into the level
adjusting fittings from the bottom.
Slide tumble dryer to its permanent location. Adjust
the leveling legs until the unit is level, or no more than
0.125 inch (3.18 mm) higher in the front. Refer to
Figure 3. Tumble Dryer must not rock. Lock leveling
legs with nuts previously installed.
NOTE: The front of the tumble dryer should be
slightly higher than the rear (approximately 0.125
inch [3.18 mm]). This will prevent the clothes, while
tumbling, from wearing on the door glass gasket.
IMPORTANT: Keep tumble dryer as close to floor
as possible. The unit must rest firmly on floor so
weight of tumble dryer is evenly distributed.
Fire Suppression System
Check Local Codes and Permits
Call your local water company or the proper municipal
authority for information regarding local codes.
IMPORTANT: It is your responsibility to have
ALL plumbing connections made by a qualified
professional to assure that the plumbing is
adequate and conforms to local, state, and federal
regulations or codes.
IMPORTANT: It is the installation or owner’s
responsibility to see that the necessary or required
water, water pressure, pipe size, or connections are
provided. Manufacturer assumes no responsibility
if the fire suppression system is not connected,
installed, or maintained properly.
Water Requirements
IMPORTANT: Water must be supplied to the fire
suppression system, or the fire suppression system
will not operate as intended.
Connection point to the electric water solenoid valve is
a 3/4 inch (19 mm) hose. The fire suppression system
equipped tumble dryer must be supplied with a
minimum water pipe size of 1/2 inch (12.7 mm) and be
provided with a minimum of 20 psi (138 kPa) and a
maximum of 120 psi (827 kPa) of pressure at all times.
Flowrate must be no less than, but approximately
15 gallons (57 liters) per minute.
Figure 3
T483I
NOTE: Water pressure under 20 psi (138 kPa) will
cause low flow and water leakage at water solenoid
valve.
If the rear of the tumble dryer or the water supply is
located in an area where it will be exposed to cold/
freezing temperatures, provisions must be made to
protect these water lines from freezing.
IMPORTANT: Temperature of the water supply
must be kept between 40°F and 120°F (4.4°C and
48.9°C). If water in the supply line or water
solenoid valve freezes, the fire suppression system
will not operate.
tumble dryer register a temperature below 40F°
(4.4°C), the fire suppression system control will
lock out. This feature protects against operation of
the tumble dryer with a possible frozen water
supply. Only when the temperature sensors register
a temperature above 40F° (4.4°C) will the machine
reset for operation.
IMPORTANT: Flexible supply line/coupling must
be used. Solenoid valve failure due to hard
plumbing connections will void the warranty. It is
recommended that a filter or strainer be installed
in the water supply line.
Water Connections
Two hoses and a Y-valve are provided with the tumble
dryer to allow for connection of water supply to
tumble dryer. The water connections are made to the
bushings of the water solenoid valve, located on the
rear of the tumble dryer. The Y-valve provides a single
female hose connection (Standard US 3/4-11 1/2 NH
thread). Refer to Figure 4 and Figure 5.
Connect inlet hoses to water supply. Flush the lines for
approximately two minutes to remove any foreign
materials that could clog the screens in the water
mixing valve. This is especially important when
installing a tumble dryer in a newly constructed or
renovated building. Then connect the hoses to the
Y-valve; connect the Y-valve to the connections at the
rear of the tumble dryer.

To connect the two hoses (supplied with tumble
dryer), insert rubber washers (from literature pack) in
water inlet hose couplings. Refer to Figure 5.
TMB2000N
IMPORTANT: Thread hose couplings onto valve
connections finger tight, then turn 1/4 turn with
pliers. Do not cross thread or overtighten
couplings.
IMPORTANT: Hoses and other natural rubber
parts deteriorate after extended use. Hoses may
develop cracks, blisters or material wear from the
temperature and constant high pressure they are
subjected to.
All hoses should be checked on a yearly basis for
any visible signs of deterioration. Any hose showing
the signs of deterioration listed above should be
replaced immediately. All hoses should be replaced
every five years.
NOTE: Longer inlet hoses are available (as
optional equipment at extra cost) if the hoses
supplied with the tumble dryer are not long enough
for installation. Order hoses as follows:
Part No. 20617 Inlet hose 8 feet (2.44 m)
Part No. 20618 Inlet hose 10 feet (3.05 m)
NOTE: Replacement outlet hoses are available (at
extra cost). Order 44073301 Hose, 39 in. (99 cm).
Electrical power must be provided to
tumbler at all times. The fire suppression
system will be inoperative if the main
electrical power supply is disconnected.

Electrical Requirements
No independent external power source or supply
connection is necessary. Power to operate the 24 Volt
fire suppression system is from the rear junction/
contactor box.
Auxiliary Alarm
TMB1999N
The fire suppression system provides an auxiliary
output signal when the system is activated. During
tumble dryer installation, you have the option to
connect a separate alarm system to this auxiliary
output. Potential uses of the auxiliary output include,
but are not limited to: (1) sounds an alarm, (2)
activates a building sprinkler system, (3) notifies a fire
department, etc. Use of the auxiliary output is not
required for the fire suppression system to operate, but
may be used for additional protection.
The connection to the auxiliary output is made through
the FS-1 and FS-2 fast-on connections inside the fire
suppression control box. Refer to Figure 6. The relay
is rated for 24 VAC, 5.2 Amp, sealed current.
NOTE: The auxiliary output is activated during
fire suppression system maintenance test sequence.
Consider this fact prior to your system test every
three months. (Example: If the external system
uses the auxiliary output to call the fire
department, inform the fire department before and
after the fire suppression system maintenance test.)
This option allows the tumble dryer depth to be
reduced to 34 5/16 inches (871 mm). The tumble dryer
should then fit through a 36 inch (914 mm) door
opening (actual 34.5 inches [876 mm]).

Installing CE Gas Drying Tumble
Dryer
General Information
This information is to be used when installing gas
tumble dryers in countries and/or on gases different
than the machine’s factory configuration. Tumble
Dryers are supplied from the factory for operation on
3
Natural Gas 1000 Btu/cu. ft. (8914 kcal/m
Gas 2500 Btu/cu. ft. (22,250 kcal/m
3
of GB/IE/PT/ES/IT/GR/LU/CH/BE. 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
For converting models from Natural Gas to L.P. Gas:
050 series – M4544P3
075 series – M4545P3
Serial plates supplied from the factory are configured
for GB/IE/PT/ES/IT/GR/LU/CH/BE. These
instructions pertain to the situations when the country
of use or gas supply is different than that on the serial
plate.
These instructions are only valid if the following
country code is on the appliance: GB/IE/PT/ES/IT/
GR/LU/CH/BE. If this code is not present on the
appliance, it is necessary to refer to the technical
instructions which will provide the necessary
information concerning the modification of the
appliance to the condition of use for the country.
Before installation, check that the local distribution
conditions, nature of gas and pressure, and the
adjustment of the appliance are compatible.
Tab l e 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 (5 kPa), order Regulated
Natural Gas machines and convert according to
Tab l e 1 .
When converting the tumble dryer to a
different gas or pressure, first verify that
the supply inlet pressure is equipped with
a pressure regulator (located ahead of the
tumble dryer) that will maintain the gas
supply at the inlet pressure specified.

A drying tumble dryer produces
combustible lint. To reduce the risk of
fire, the tumble dryer must be exhausted
to the outdoors.
W057R1
To reduce the risk of fire, DO NOT use
plastic or thin foil ducting to exhaust the
tumbler.
W773
To reduce the risk of fire and
accumulation of combustible gases, DO
NOT exhaust tumble dryer 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.
W059R1
WARNING
To reduce the risk of fire due to increased
static pressure, we do not recommend
installation of in-line secondary lint filters
or lint collectors. If secondary systems
are mandated, frequently clean the
system to assure safe operation.
W749
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 openings in rooms containing tumble
dryer(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 tumble dryers are in operation. Do not locate
gravity vented appliances between tumble dryer(s) and
make-up air openings. If it is necessary to duct makeup air to tumble dryer(s), increase area of duct work by
25% to compensate for restrictions in air movement.
Venting
Layout
Whenever possible, install tumble dryers 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 tumble dryer. Doing so would prevent adequate air
supply to the tumble dryer combustion chamber.
Make-Up Air
A tumble dryer is forced air exhausted and requires
provisions for make-up air to replace air exhausted by
tumble dryer.
IMPORTANT: Do not obstruct flow of combustion
and ventilation air.

Make-up air openings with louvers will restrict
airflow. The opening must be increased to compensate
for area taken up by louvers.
IMPORTANT: Installing in-line filters or lint
collectors will cause increased static pressure.
Failure to maintain the secondary lint system will
decrease tumble dryer efficiency and may void
machine warranty.
For maximum efficiency and minimum lint
accumulation, tumble dryer air must be exhausted to
the outdoors by the shortest possible route.
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, thin foil or Type B ducts rigid metal ducts are recommended. Use exhaust ducts
made of sheet metal or other noncombustible material.
DO NOT use sheet metal screws or fasteners on
exhaust pipe joints which extend into the duct and
catch lint. Use of duct tape or pop-rivets on all seams
and joints is recommended, if allowed by local codes.
Verify that old ducts are thoroughly cleaned out before
installing new tumble dryer(s).
70457901ENR7
Page 35
Exhaust Requirements
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.
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
noncombustible material. Refer to Figure 19.
IMPORTANT: For best performance provide an
individual exhaust duct for each tumble dryer. Do
not install a hot water heater in a room containing
tumble dryers. It is better to have the water heater
in a separate room with a separate air inlet.
Individual Venting
For maximum efficiency and performance, it is
preferred to exhaust tumble dryer(s) individually to the
outdoors.
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 tumble
dryer.
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 tumble dryer.

equivalent length of 14 feet (4.3 m) of duct and two
90° elbows is:
Equivalent Length
= 14 ft. (4.3 m) + (2) 90° elbows
= 14 ft. (4.3 m) + 14 ft. (4.3 m) + 14 ft. (4.3 m)
= 42 ft. (12.8 m)
With the tumble dryer in operation, airflow at any
point in the duct should be at least 1200 feet/min.
(366 m/min.) to ensure that lint remains airborne. If
1200 feet/min. (366 m/min.)) per minute cannot be
maintained, schedule monthly inspections and
cleaning of the ductwork.
NOTE: The maximum length of a flexible metal
duct must not exceed 7.87 ft. (2.4 m) as required to
meet UL2158, clause 7.3.2A.
NOTE: Static back pressure must be measured
with the tumble dryer running.
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 3 to
determine equivalent venting.
While it is preferable to exhaust tumble dryers
individually to the outdoors, a main collector duct may
be used if it is sized according to Figure 20 and
Figure 21. 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 4 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.
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 bar) as specified
on the installation sticker on the rear of tumble dryer.
Static back pressure must be measured with all tumble
dryers vented into the collector operating.
NOTE: Never connect a tumble dryer duct at a 90°
angle to the collector duct. Refer to Figure 18.
Doing so will cause excessive back pressure,
resulting in poor performance. Never connect two
tumble dryer exhaust ducts directly across from
each other at the point of entry to the collector
duct.
With the tumble dryer in operation, airflow at any
point in the duct should be at least 1200 feet/min.
(366 m/min.) to ensure that lint remains airborne. If
1200 feet/min. (366 m/min.) cannot be maintained,
schedule monthly inspections and cleaning of the
ductwork.
To reduce the risk of fire or explosion, DO
NOT CONNECT THE GAS LINE TO THE
TUMBLE DRYER IF THE GAS SERVICE IS
NOT THE SAME AS THAT SPECIFIED ON
THE TUMBLE DRYER SERIAL PLATE! It
will first be necessary to convert the gas
burner orifice and gas valve. Appropriate
conversion kits are available.
W060R1
To reduce the risk of gas leaks, fire or
explosion, use a new flexible stainless
steel connector.
W774
WARNING
To reduce the risk of fire or explosion, if
the tumble dryer is to be connected to
Liquefied Petroleum (L.P.) gas, a vent to
the outdoors must be provided in the
room where the tumble dryer is installed.

•Sediment traps
•Shut-off valves
•Supply pressure taps
It is important that equal pressure be maintained at all
tumble dryer 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
Figure 23.
IMPORTANT: The tumble dryer 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
(3.45 kPa, 34.5 mbar).
NOTE: For gas valves with a manual shut-off
switch on the gas valve, the shut-off switch does not
protect the valve from this pressure test. Use the
individual manual shut-off valve from the gas
supply piping system to protect the gas valve.
IMPORTANT: The tumble dryer 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 psig (3.45 kPa, 34.5 mbar).

Grounding Instructions
NOTE: To ensure protection against shock, this
tumble dryer MUST be electrically grounded in
accordance with the local codes, or in the absence
of local codes, with the latest edition of the National
Electrical Code ANSI/NFPA No. 70. In Canada the
electrical connections are to be made in accordance
with CSA C22.1 latest edition Canadian Electrical
Code, or local codes. Electrical work should be
done by a qualified electrician.
This tumble dryer must be grounded. In the event of
malfunction or breakdown, grounding will reduce the
risk of electric shock by providing a path of least
resistance for electric current. This tumble dryer must
be connected to a grounded metal, permanent wiring
system; or an equipment grounding conductor must be
run with the circuit conductors and connected to the
appropriate ground location.
•Metal conduit and/or BX cable is not considered
ground.
•Connecting the Neutral from the electrical
service box to the tumble dryer ground screw
does not constitute a ground.
•A dedicated ground conduit (wire) must be
connected between the electrical service box
ground bar and tumble dryer ground screw.
For CE Models Only
All OPL (non-vend) models are factory-equipped with
an emergency stop button on the front panel. If the
emergency stop function is desired on coin-operated
models, an external emergency stop button may be
installed.
NOTE: Activation of the emergency stop switch
stops all machine control circuit functions, but
DOES NOT remove all electrical power from
machine.
The following steps outline the procedure for
connecting the electrical service to the tumble dryer.
NOTE: The wiring diagram is located in the
junction box.
1. Install a circuit breaker as close to the tumble
dryer as possible. If more than one tumble dryer
is being installed, a disconnect switch or circuit
breaker should be provided for each. This will
make it possible to disconnect each tumble dryer
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 24.
3. Check the electrical service phase sequence
(three phase only) as follows:
a. Energize the electrical service (on reversing
tumble dryers, ensure nonreversing is
selected) and momentarily start the tumble
dryer. 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 050 and 075
series models and counterclockwise on F75
series models.
b. Disconnect and reverse any two service leads
on the terminal block (example: switch L2
and L3 on terminal block).
Changing the transformer configuration jumper is
required, PRIOR TO SUPPLYING POWER TO
THE MACHINE, if any of the following apply:
IMPORTANT: Failure to install the proper
configuration jumper may result in damage to

NOTE: Use copper conductors only.
NOTE: Connect to individual branch circuit.
NOTE: 3 Phase Only – Each tumble dryer 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).
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 tumble dryer steam coil connections.
W480R2
NOTE: Machines require a constant 80 to 100 psig
(5.3 to 6.9 bar) steam service for optimum
operation. The maximum allowable steam pressure
for use with 50 Hertz tumble dryers is 125 psig
(8.6 bar). In no case may the pressure exceed the
above value.
Obtain specific steam service pipe sizes from steam
system supplier or a qualified steam fitter.
•Refer to Figure 26 for proper steam pipe
configurations.
•To prevent condensate draining from headers to
tumble dryer, piping should have a minimum
12 inch (305 mm) rise above respective header.
Do not make steam connection to header with a
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 tumble dryer. 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 tumble
dryer 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.
•Install vacuum breaker (optional), bucket trap
with built-in strainer and check valve. For
successful operation of tumble dryer, install trap
18 inches (457 mm) below coil and as near to the
tumble dryer 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 tumble dryer. Gravity return requires
entire return plumbing be below steam coil
outlets.
•Install union and shut-off valve in return line and
make final pipe connections to return header.
NOTE: To prevent water hammering, route return
lines below outlets of steam coils.
Piping Recommendations
•Trap each steam coil individually. Always keep
the trap clean and in good working condition.
•When tumble dryer is on the end of a line of
equipment, extend header at least 4 feet (1.2 m)
beyond tumble dryer. 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 tumble
dryer.
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 26 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 tumble
dryer.
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 tumble dryer.
NOTE: The following information is for
models with an SD control suffix only.
Power-Up Mode
When power is applied to the tumble dryer, 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
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.
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.
Setting Dry Time Dipswitches
To change the dry time on the tumble dryer,
combinations of dipswitches can be set on the control.
There are eight dipswitches on the tumble dryer
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.
Models Through Serial No. 0908xxxxx
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 Ta bl e 12.
Models Starting Serial No. 0909xxxxx
The seventh switch is 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 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 Tab le 1 2.
The eight switch is used for the cycle reset. If the
switch is OFF (default), the control will save the time
left on a cycle in case of a power failure. If the switch
is ON, the control will clear the cycle and go back to
Ready Mode if there is a power failure.
The control reads the dipswitch settings at power-up.
The control must be powered down to change the
dipswitch settings.
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.
NOTE: The control must be powered down for 10
seconds before the dipswitches can be changed.
To remove any cycle time that may have accumulated
on the control during setup, the cycle time on the
control can be reset to zero.
To reset the time, unplug the tumble dryer and set
dipswitch 8 to ON position. Restore power to the
tumble dryer for 10 seconds and once again unplug
tumble dryer. Set dipswitch 8 to OFF position and
restore power to the tumble dryer.

Power-Up
Upon applying power to the tumble dryer, the display
will show “PAy ” and the DRYING and COOLING
LEDs will be off until coins are deposited to increase
the tumble dryer run time. When time is displayed, the
default (LOW) temperature setting LED will be on
until a different temperature setting is selected.
Power Failure
If a power loss occurs during operation, a cycle will
not resume until the START button is pressed. To
cancel the remaining cycle, press the internal CLEAR
button.
Coin Operation
The tumble dryer run time is determined by the preprogrammed run time per coin and the number of
coins deposited into the tumble dryer. The maximum
time that can be accumulated and displayed is 99
minutes. The drying time is the difference between the
run time and the cooling time. The cooling time is preprogrammed to be 2 to 5 minutes. The drying
temperature can be selected from LOW, MEDIUM, or
HIGH temperature settings by pressing the TEMP
button.
Coin Programming
The Coin board programming mode can only be
entered when “PAy” is displayed. DIP switch #7 must
be in the OFF position.
Programming is enabled by setting DIP switch #8 to
the ON position.
The programming mode is entered by pressing and
holding the CLEAR button for three seconds.
The programming follows the following parameter
order:
1. Tumble dryer run time per coin (DRYING),
COOLING time, HIGH temperature setpoint,
MEDIUM temperature setpoint, LOW
temperature setpoint.
3. The hidden front panel increment and decrement
keys are used to change the value.
4. The CLEAR button is used to recall the default
value.
5. The START button is used to step to the next
parameter.
6. After the last parameter, “End” will be flashing.
7. Press the START button one last time to store the
settings and exit the program mode.
8. “PAy” will be displayed.
9. If it is determined that the data did not program
correctly, the error message “E2F” will flash for
4 seconds, and then the default coin parameters
will be used.
The tumble dryer run time per coin is programmable
for 1 to 20 minutes with the default preset to 10
minutes.
The cooling run time is programmable from 2 to
5 minutes with the default preset to 2 minutes.
The three temperatures setpoints are programmable for
100ºF (38ºC) to 185º/195ºF (85º/90ºC) with the
following default settings:
- HIGH equal to 185ºF (85ºC)
- MEDIUM equal to 150ºF (66ºC)
- LOW equal to 135ºF (57ºC)
Stop
When in the Coin mode, the tumble dryer will stop if
the tumble dryer door is opened while the tumble dryer
is running. If the CLEAR button, located behind the
board, is pressed, the tumble dryer will stop, the
tumble dryer time will be zeroed and the display will
show “PAy”.
Coin Count
The unit will count the number of coins deposited.
Setting DIP switch #7 to the ON position will display
the coin count since it was the last reset.
To reset the count, press the CLEAR button and “00”
will be displayed.
If the coin count is greater than “999”, the display will
flash “999”.
Setting DIP switch #7 to the OFF position will return
the display to “PAy
”.
2. An LED will be on to indicate which parameter is
flashing on the display.
2. Select the desired program number to change.
The LED should be flashing.
3. Select DRY TIME. Set the time with the Up/

Operation.
7. Press and hold the Program Select button about
3 seconds until the LED stops flashing. The
selected program number is now programmed. If
the Program button is pressed for less than
3 seconds, the controller will cancel the program
and display the next program’s settings. If not
programmed correctly, the display will flash
“E2F” for 4 seconds, and the default settings will
be used. Follow steps 4 through 7 to reprogram
any program number. When finished, set DIP
switch #8 to OFF. The programs are now stored.
8. During the Program Mode, if the Up/Down
arrows, REV, or Display button is not pressed
within 10 seconds, the default program settings
will be used.
9. Temporary Reprogramming of Current Programs
(OPL ONLY).
10. The Drying Time, Cooling Time, Temperature,
and Reversing Mode of a program currently in
use may be modified simply by adjusting any or
all of the program parameters for that program,
as needed. Once a modification has been made,
the current program LED will flash indicating
that it has been modified.
11. Use the Up/Down arrows to adjust program time.
12. Use the Display Select button to choose between
Drying Time, Cooling Time, and Temperature.
Then use the Up/Down arrows to adjust the times
and temperature.
14. To cancel this temporary programming mode
push the STOP button once to stop the current
cycle and once more to cancel the modified
program settings. The program will revert back
to its original settings.
Reversing Operation
1. When the LOCAL reversing operation is
selected, the reversing times are stored in the
EEPROM which is located on the controller
board. If the values stored are determined to be
invalid, the clockwise and counterclockwise
times will default to 60 seconds, and the dwell
time will default to 4 seconds.
2. The reversing time program has the following
sequence: (1) clockwise time, (2) dwell time and
(3) counterclockwise time.
3. To program new reversing times DIP switches #3
and #8 must be on.
4. Press and hold the reverse button (REV) for
3 seconds to display the clockwise time.
5. Use the Up/Down arrows to set the clockwise
time within the range of 30-120 seconds.
6. Press REV to display the dwell time.
7. Use the Up/Down arrows to change the dwell
time within the range of 3-10 seconds.
8. Press the REV button to display the
counterclockwise time.
9. Use the Up/Down arrows to change the
counterclockwise time within the range of 30120 seconds.
10. Press the REV button to save these settings and
leave DIP switch #3 in the ON position and flip
DIP switch #8 to the OFF position.
When the DMP controller is retrofitted to an existing
tumble dryer with the reversing feature, off board
reversing will be required and DIP switch #3 on the
DMP must be in the OFF position and the DMP must
be connected to the Reversing Timer Board for proper
operation. The DMP settings for clockwise, dwell, and
counterclockwise times are no longer valid when used
with the Reversing Board. Instead these settings are
made on the Reversing Timer Board.
13. Toggle between reversing REV (illuminated) or
nonreversing REV (not illuminated). (Only for
tumble dryers with the reversing option.)
The rotation sensor must “read” the key on the basket
shaft or pulley. The sensor must be set approximately
1/4 inch from the key or pulley. Look for the light on
the sensor to come on as the key passes the sensor; this
is a correctly operating sensor. If no light appears,
either the sensor is out of range or the key/pulley or
the sensor is bad. In addition, if the light stays on
continuously, then the sensor is too close to the
component or the sensor is bad.
Safety Tumble/Anti-Wrinkle
At the end of the cool down cycle, the tumble dryer
will stop and display “END.” The DMP control will
automatically rotate the basket for 5 seconds every
2 minutes for a total of 20 minutes, until some
function of the tumble dryer is activated/deactivated
by the user.
Operational Check for the Board Diagnostics
1. “dor” indicates that the loading or lint door is
open.
2. Cycle the tumble dryer to check if the buzzer
activates.
3. “P-F” indicates that the thermistor is short
circuited or open circuited.
4. “bbt” indicates a broken belt condition or a faulty
rotation sensor. (Only available on tumble dryers
with the rotation sensor.)
5. Hold the START button to display the drum
RPM’s; the display will read “r##” where ## are
the RPM’s. (Only available on tumble dryers
with the rotation sensor.)
70458601 and 70458701 controls cannot be
serviced by the user. If any control failures
are detected, the controls must be replaced
by qualified service personnel. Risk of
explosion or fire can result if the control
module has been opened or with any
attempts to repair it and the warranty is
void.

Troubleshooting for Models Starting
3/11/13
Before troubleshooting the system, check the
following items:
- Verify all mechanical and electrical connections are
secure and tight.
- Verify all system wiring is correct.
- Verify there is a proper system ground. The igniter,
flame sensor and igniter module must share a common
ground with the burner. Nuisance shutdowns are often
caused by a poor or erratic ground.
- Verify that the system is powered and that the control
is calling for heat.
- If the control proceeds to an error code on the red
diagnostic LED, troubleshoot per the Fault conditions

assembly should be located so that the tips are inside
the flame envelope and about 1/2 inch (1.2 cm) above
the base of the flame. Refer to Figure 53.
Figure 53
Flame Current Measurement
Flame current is the current that passes through the
flame from sensor to ground. To measure flame
current, connect a True RMS or analog DC microammeter to the FC+ and the FC- terminals. The
reading should be 1.0 micro-amps DC or higher. If the
meter reads negative or below “0” on the scale, the
meter leads are reversed. Re-connect leads with proper
polarity.
Alternately, a Digital Voltmeter may be used to
measure the DC voltage between the FC+ and FCterminals. Each micro-amp of flame current produces
1.0 VDC, so a reading of 2.6 VDC would equate to 2.6
micro-amps.
A good burner ground that matches the control ground
is critical for reliable flame sensing.
Ignition Control Operation for NonCE Models Through 3/10/13
Power Up
When power is applied to the ignition control, the
control will begin the ignition sequence within 1 – 3
seconds prepurge waiting time.
Ignition Sequence
The control begins the ignition sequence after
prepurge by powering the ignitor and opening the gas
valve. The ignitor will remain on either until a flame is
sensed or until a maximum of ten (10) seconds
(10 +0/-4 sec) has elapsed. If a flame is established
and lost during the 10 second period, the ignitor will
be powered up again in an attempt to re-ignite the gas.
If no flame is detected within the ten (10) second
ignition sequence, the control will terminate power to
the gas valves, ignitor, and enter lockout within 5
seconds.
Normal Operation
Once a flame has been established, the spark ignitor
will stop sparking and the control will continually
monitor all inputs. If the controller senses a loss of
flame after flame is established, the gas valve will
remain energized and sparking will commence within
one second of the flame loss. If flame reattempt fails,
lockout will occur within 11 seconds of initial flame
loss.
Control Lockout
When the control locks out, the gas valve will be
closed and all requests for heat will be ignored. The
lockout mode may only be discontinued by
interrupting power to the control or cycling the
thermostat. After this occurs, the control will restart
with its normal power up and ignition sequence.
Low Voltage Detection
The control will have capability for detection of a low
voltage input condition. If input voltage on power up
is below 19.0VAC +0.8VAC/-0.5VAC, the control will
disable output to gas valve control relay. If input
voltage rises above 19.8VAC for at least three (3)
seconds, the control will then re-enable function of the
gas valve control relay and ignition sequence may
begin. On powerup, the control function must always
be disabled if greater than 19.8VAC.
Termination of Flame
Normal flame termination occurs when the thermostat
has been satisfied, meaning there is no immediate need
for more heat. The thermostat will disconnect power
from the ignition control, which will cause the gas
valve to close and the flame to go out. After a short
period of time, not less than 1 second, the thermostat
will cool down and close causing power to be
reapplied to the ignition control. When this occurs, the
control must complete the same prepurge and ignition
sequence specified above.
Ignition Control Operation for CE
Models Through 3/10/13
Power Up
After 24VAC is applied to the ignition control pins
24V and GND, the Diagnostic LED on the ignition
control will turn orange/yellow. If a fault is detected
the ignition control will enter Lockout Mode. If no
faults are detected, the Diagnostic LED will turn
Green and the ignition control will enter Standby
Mode.
Standby Mode
While in Standby Mode, the ignition control will
continually monitor the system for faults. Once
24VAC is applied to terminals TH and GND on the
control, the ignition control will enter Start Up Mode.
Start Up Mode
During Start Up Mode, the ignition control will
monitor the system for faults and begin the ignition
sequence. If no faults are present, the ignition control
will begin the ignition sequence by entering an 18
second waiting period. During this time the Green
LED on the ignition control will switch between Red
and Green, before maintaining a Green color.
After the waiting period, the ignition control will turn
on the igniter and gas valve. The igniter will remain on
until a flame is sensed, or up to 10 seconds.
Once a flame has been sensed the ignition control will
stop sparking, the gas valve will remain on and
ignition control will enter Run Mode.
If a flame is not sensed, the ignition control will then
begin two additional retrials for ignition. The ignition
control will re-enter the 18 seconds waiting period
before the ignition control makes another attempt at
ignition. If the three attempts at ignition fail, the
ignition control will enter Lockout Mode.
Run Mode
While in Run Mode the ignition control leaves the gas
valve on, monitors the flame signal, and leaves the
igniter off.
If a flame signal is lost during Run Mode, one
additional retrial for ignition will take place within one
second. The ignition control will restore the spark for
approximately 10 seconds. If the ignition re-attempt
fails, the ignition control will enter Lockout Mode.
The ignition control will remain in Run Mode until
24VAC is removed from terminals TH and GND on
the control.
Termination of Flame
The flame will go out when power is removed from
ignition control. The ignition control will turn off the
gas valve and enter Standby Mode.
Lockout Mode
When Lockout Mode is entered, the ignition control
will remove power to the gas valve, the igniter will
turn off, the Lockout/Reset Light will turn on, and the
Diagnostic LED will display the appropriate Error
Code.
Lockout Manual Reset
Lockout Mode is cleared by pressing an external reset
switch for three seconds. The ignition control will
clear all error codes and enter Standby Mode. During
Lockout Manual Reset, the Diagnostic LED on the
ignition control flashes red and orange, and the Reset
Light remains on until the ignition control is reset.
After the Reset Light turns off, stop pressing the
switch. Holding the reset for three seconds after
lockout has been cleared will cause a fault and result in
entering Lockout Mode again.
System Tests
The following system tests are performed during
normal operation. System tests are performed at a
minimum of every 24 hours.
Low Voltage Detection
If the voltage between terminals TH and GND on the
control is below 18.75VAC +/- 0.75VAC for more than
3 seconds the ignition control will turn off the gas
valve and will not attempt to spark. The Diagnostic
LED will display Error Code 5. The ignition control
will not enter Lockout Mode if a low voltage condition
is detected, but will enter Standby Mode and wait for
the low voltage condition to be cleared.
If the voltage between terminals TH and GND on the
control rises above 19.75VAC +/- 0.1VAC for at least
3 seconds, the ignition control will then enter Start Up
Mode.
Low Voltage Detection test is disabled during Run
Mode.
Gas Valve
The ignition control verifies that the gas valve is
connected. Failure of this test results in the ignition
control entering Lockout Mode with the Diagnostic
LED displaying Error Code 2.
The Unexpected Presence of Flame test is performed
when no flame is expected. Failure of this test results
in the ignition control entering Lockout Mode with the
Diagnostic LED displaying Error Code 3.
Flame Monitoring
During the Flame Monitoring test, the flame is
checked to ensure the gas is being burned when the gas
valve is on. Failure of this test will result in the
ignition control entering Lockout Mode with the
Diagnostic LED displaying Error Code 3.

Gas Burner Air Shutter
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.
5. After air shutter is adjusted for proper flame,
tighten air shutter adjusting screw securely.
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:
Refer to Figure 55.
1. Open the access panel and remove the burner
inspection hole plate.
2. Start the tumble dryer and check the flame
pattern. If the flame pattern is straight up,
insufficient air is flowing through the tumble
dryer. A flame pattern that flares to the right and
left indicates no air is flowing through the tumble
dryer. 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.
3. To adjust the air shutter, loosen air inlet shutter
adjusting screw.
4. Open or close air shutter as necessary to obtain
proper flame intensity.
The tumble dryer 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 tumble dryer.
W072R1

Airflow Switch
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.
IMPORTANT: Airflow switch vane must remain
closed during operation. If it opens and closes
during the drying cycle, this indicates insufficient
airflow through the tumble dryer. 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.
Loading Door 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 56 and proceed as follows:
1. Close door and start tumble dryer, 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).
2. Slowly close the loading door. When door is
51 mm (2 inches) 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.”
3. If the actuating bracket does not operate the
switch at the appropriate door closure, bend the
actuating switch arm in or out to achieve proper
actuation.
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.
The door catch must be adjusted to have sufficient
tension to hold loading door closed against force of
load tumbling against it. Proper adjustment is when
7-15 pounds (0.48-1.03 bar) pull is required to open
door.
If adjustment is required, refer to Figure 57 and
proceed as follows:
To adjust, open door, loosen acorn nut and turn door
strike screw in or out as required. Tighten acorn nut.
Drive Belt
Nonreversing Models
Refer to Figure 58.
Proper tension is when the drive V-belt can be
depressed approximately 0.5 inch (13 mm) by
applying light thumb pressure at a point midway
between the sheave and motor pulley.
1. Remove guard from rear of tumble dryer.
2. To adjust belt tension, loosen idler housing bolts
holding idler housing assembly to the guide rails.
3. Position housing assembly by turning adjusting
bolt until proper belt tension is reached, then
retighten idler housing bolts.
4. Replace the guard on rear of tumble dryer.
