Installation
The stacked tumbler has a fifth leveling leg which is
shipped in the up position. The fifth leveling leg
MUST BE installed properly on the lower left side of
the blower housing to stabilize the tumbler. Refer to
Position and Level the Tumbler
Unscrew the four shipping bolts (one at each corner).
Remove tumbler from skid carefully to avoid putting
pressure on the lower blower housing or motor
assembly.
After leveling with the four cabinet leveling legs,
lower the fifth leveling leg so it contacts the floor, and
then secure the screws.
NOTE: Do not throw bolts away – they are the
leveling legs.
Remove four nuts from the literature package, and
screw one fully on to each leveling leg.
CAUTION
Screw the four leveling legs (bolts) back into the level
adjusting fittings from the bottom.
The stacked drying tumbler has a 5th
leveling leg on the blower housing. It is very
important to properly adjust this leg. Unit is

NOTE: The front of the tumbler 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 tumbler as close to floor as
possible. The unit must rest firmly on floor so
weight of tumbler is evenly distributed.

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.

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.

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

exhaust outlet does not exceed the maximum
allowable pressure specified on the installation sticker
on the rear of the tumbler.

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).
= 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
minute cannot be maintained, schedule monthly
inspections and cleaning of the ductwork.

NOTE: Never connect a tumbler duct at a 90° angle
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
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).
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.
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

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.

• 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

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

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
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.

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
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

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.
