Installation

Pre-Installation Inspection

Location Requirements

Upon delivery, visually inspect the crate, carton and

parts for any visible shipping damage. If the crate,

carton, or cover is damaged or signs of possible

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.

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:

non-combustible material. Refer to Figure 9.

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.

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)

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 T a ble 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

codes.

NOTE: Inside of duct must be smooth. Do not use

sheet metal screws to join sections.

Consult your local building code for regulations which

may also apply.

70304601

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 T a ble 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.

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 T able 8 for these models:

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

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

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.

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.

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 T able 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.
