Figures 24

FACILITIES REQUIRED

FLOOR

Drying tumbler may be installed on any level floor
capable of supporting 100 pounds per square foot
(488 kg/m2). Floor covering materials such as
carpeting or tile should be removed.

LAYOUT

Whenever possible, tumbler should be installed along
an outside wall where duct length can be kept to a
minimum, and make-up air can be easily accessed.

M412616

Construction must not block airflow at top rear of
tumbler. Doing so would prevent adequate air supply
to tumbler’s combustion chamber.

VENTING

For maximum efficiency and minimum lint
accumulation, tumbler air must be exhausted to
outdoors by shortest possible route.

31

Proper sized exhaust ducts are essential for proper
operation. All elbows should be sweep type. Do not
install elbows with a radius less than shown in table
below. Exhaust ducts must be assembled so interior
surfaces are smooth to reduce accumulation of lint.
Do not use sheet metal screws to join vent sections.
Improperly sized or assembled ductwork causes
excess back pressure which results in slow drying,
lint collecting in duct, lint blowing back into room, and
increased fire hazard.

Exhaust ducts shall 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 exhaust duct pierces a combustible wall or
ceiling, an opening having a diameter of 4 inches
(10.2 cm) larger than diameter of exhaust duct shall
be provided, with duct centered in opening. When
ducts pass through walls, ceilings, floors or partitions,
space around the duct shall be sealed with non­combustible material. See

••

• Individual Venting

••

Figures 1, 2

and

3.

For maximum efficiency and performance, it is
preferred to exhaust tumbler(s) individually to
outdoors. At no point may cross area of

installed venting be less than cross area of
exhaust thimble of tumbler.

Maximum allowable length of venting is 14 feet
(4.3 m) and two 90° elbows or equivalent. If
equivalent length of a duct required for an
installation exceeds maximum allowable
equivalent length, 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). Table below shows how to determine
equivalent venting:

DUCT

DIAMETER

6" (15.2 cm)

8" (20.3 cm)
10" (25.4 cm)
12" (30.5 cm)

EQUIVALENT LENGTH OF

STRAIGHT DUCT

One 90° elbow = 7' (2.1 m)
One 90° elbow = 9.3' (2.83 m)
One 90° elbow = 11.6' (3.5 m)
One 90° elbow = 14' (4.3 m)

With tumbler in operation, airflow at any point in
duct must be at least 1200 feet (366 m) per
minute to insure that lint remains airborne.

••

• Collector Venting

••

While it is preferable to exhaust tumblers
individually to outdoors, a main collector duct may
be used if it is sized according to

Figure 3.

NOTE: This illustration indicates minimum
diameters, and should be increased if collector
length exceeds 20 feet (6.1 m).

Collector duct may be rectangular in cross
section, as long as area is not reduced. Provisions
should be made for lint removal and cleaning of
collector duct.

Collector duct must be tapered, as shown in

Figure 3.

Individual tumbler ducts must enter the

collector duct at a 45° angle in direction of air flow.

Never connect a tumbler duct at a 90° angle to
collector duct. Doing so will cause excessive
back pressure, resulting in poor performance.
Never connect two tumbler exhaust ducts
directly across from each other at point of
entry to collector duct.

Collector system must be designed so static back
pressure measured 12 inches (30.5 cm) from
exhaust thimble does not exceed maximum
allowable pressure specified on installation sticker
on rear of tumbler. Measured with all tumblers
running that are vented into collector.

MAKE-UP AIR

A tumbler is forced air exhausted and requires
provisions for make-up air to replace the air
exhausted by tumbler.

Manufacturer’s recommended make-up air opening
for each tumbler is 144 square inches (928 sq. cm)
for 30 and 50 pound tumblers and 195 square inches
(1258 sq. cm) for 75 pound tumblers. At a minimum,

tumblers must have at least 1 in2 (2.54 cm2) of
opening for every 1000 BTU/hr (252 Kcal/hr) of
input rating for proper combustion.

Example: A tumbler with a rated input of 120,000

BTU/hr (30,240 Kcal) requires 120 in
(774 cm2) of free opening.

2

Equivalent Length (feet) (m) =

1.17 x Duct Diameter (inches) (cm)

Example: A 6-inch (15.2 cm) diameter duct’s

equivalent length of 14 feet (4.3 m) of duct
and two 90° elbows is:

Equivalent length

= 14 feet (4.3 m) + (2) 90° elbows
= 14 feet (4.3 m) + 7 feet (2.1 m) + 7 feet (2.1 m)
= 28 feet (8.5 m)

Protective louvers in opening to outdoors can reduce
air movement by approximately 40%. Opening must
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 vents when
all tumblers are in operation. Do not locate gravity
vented appliances between tumbler(s) and make-up
air openings. If it is necessary to duct make-up air to
tumbler(s), increase area of work by 25% to
compensate for any restriction in air movement.

32

M412616

WARNINGWARNING

WARNING

WARNINGWARNING

維

Solvent gases and vapors from dry
cleaning machines create acids when
drawn through the heater of a drying
tumbler. These acids are corrosive to
the drying tumbler as well as to the
laundry load being dried. Be sure
make-up air is free of solvent gases
and vapors.

If the dry cleaning machines are in the
same area as the tumbler, then the
tumbler make-up air must come from
a source free of solvent gases and
vapors.

FOR BEST PERFORMANCE
Provide an individual exhaust
duct for each tumbler. Do not
install a hot water heater in
room containing tumblers. It is
better to have the water heater
in a separate room with a
separate air inlet.

WARNINGWARNING

WARNING

WARNINGWARNING

維

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.

NOTE: Do not install wire
mesh or screen in this
opening as lint will build up
and prevent proper discharge
of air from tumblers.

GROUNDING INSTRUCTIONS

Drying tumbler must be grounded. In event of malfunction or breakdown, grounding will reduce risk of electric
shock by providing a path of least resistance for electric current. Drying tumbler must be connected to a
grounded metal, permanent wiring system; or an equipment grounding conductor must be run with circuit
conductors and connected to PE Busbar.

維

WARNING

To reduce the risk of fire and electric shock, check with a qualified serviceman for
proper grounding procedures. Improper connection of the equipment grounding
conductor can result in a risk of electric shock.

WARNING

維

To reduce the risk of fire and electric shock, if electrical supply is coming from a
three phase service, DO NOT connect a “Stinger Leg” to a single phase machine.

WARNING

All electrical connections should be
made by a qualified electrician.

To reduce the risk of electrical shock,
de-energize the electrical circuit being
connected to the tumbler before mak­ing any electrical connections. Never
attempt to connect a live circuit.

Use the following steps to connect electrical service
to the tumbler:

1. Install a circuit breaker, as close to tumbler as
possible. If more than one tumbler is being
installed, a circuit breaker should be provided
for each tumbler. This will make it possible to
disconnect each tumbler for maintenance
purposes.

2. a. Connect conduit-encased leads to circuit

breaker.

b. Turn “off” disconnect switch on tumbler and

open junction box.

c. Insert conduit-encased leads through

one of the knockout holes in junction box.

d. Connect wire leads to disconnect switch.

3 Phase Units: Connect one lead to each
connection point.

e. Connect a ground wire to PE Busbar,

Figure 19,

in junction box.

3. Check electrical service phase sequence
(three phase only) as follows:

a. Energize electrical service and momentarily

start tumbler. Check direction of the cylinder
rotation. If cylinder rotates clockwise (viewed
from front), phase sequence is correct. If
cylinder rotates counterclockwise, proceed
with step “b”.

b. Disconnect and reverse any two leads at

connections.

4. Close junction box cover and turn “on”

POSITIONING DRYING TUMBLER

Tumbler may be removed from skid before moving to
installation location or moved while still attached to
skid. Remove tumbler from skid by unscrewing four
shipping capscrews (one at each corner) and remove
tumbler from skid. Lint panel door will have to be
removed in order to remove two front capscrews.

NOTE: Do not throw these four capscrews away
— they are the leveling legs.

LEVELING DRYING TUMBLER

Each tumbler should be leveled within ¹⁄₈ inch
(3.2 mm) from front to rear, and ¹⁄₈ inch (3.2 mm) from
side to side. Check front to rear level by rotating
clothes cylinder until one rib is at bottom, then place a

Screw four leveling legs back into level adjusting
fittings from top. Slide tumbler to its permanent
location and level. Keep tumbler as close to floor as
possible. All four legs must rest firmly on floor so
weight of tumbler is evenly distributed. Tumbler must
not rock.

level on bottom rib. Side to side level should be
checked by placing a level on front and rear of top
panel.

GAS REQUIREMENTS (Gas Drying Tumblers)

WARNING

Size of gas service pipe is dependent upon many
variables (lengths, tees, etc.). Specific pipe size
information should be obtained from gas supplier.
Refer to table in

It is important that equal gas pressure be maintained
at all tumbler gas connections. This can best be done
by installing a one inch pipe gas loop as shown in

Figures 20 and 21.

Figure 22

for general pipe size data.

維

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.

GAS CONNECTIONS (Gas Drying Tumblers)

Before connecting gas piping to tumbler, make
certain gas service is same as that specified on
nameplate (near gas connection), Page 5.

NATURAL GAS service must be supplied at 6¹⁄₂ ± 1¹⁄₂
inch water column pressure (1.62 ± .37 kPa).

L.P. GAS service must be supplied at 11 ± .3 inch
water column pressure (2.74 ± .07 kPa).

If gas service is not same as that specified, DO NOT
CONNECT THE GAS LINE TO TUMBLER! It will first
be necessary to convert gas burner orifice and gas
valve.

IMPORTANT: Any product revisions or
conversions must be made by the Manufacturer’s
Authorized Dealers, Distributors or local service
personnel.

維

WARNING

The tumbler and its individual shut-off
valve must be disconnected from the
gas supply piping system during any
pressure testing of that system at test
pressures in excess of 1/2 psig (3.45
kPa).

Purge air and sediment from gas service line before
connecting it loosely to tumbler. Purge remaining air
until odor of gas is detected, then tighten connection.

Use pipe compound, resistant to actions of L.P.
gas, on all pipe threads.

WARNING

維

Check all pipe connections, internal
and external, for gas leaks using a
soapy solution. To reduce the risk of
explosion or fire, DO NOT USE AN
OPEN FLAME TO CHECK FOR GAS
LEAKS! Gas connections should be
checked annually for leakage.

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 1/2 psig (3.45 kPa).

AND MAKING STEAM INLET
CONNECTIONS

High pressure machines require a (constant) 80 to
100 psig (5.62 to 7.03 kg/sq. cm) steam service for
optimum operation. Low pressure machines require a
(constant) 10 to 15 psig (.70 to 1.05 kg/sq. cm) steam
service for optimum operation. The following steps
outline procedure for installing steam solenoid valve
and connecting steam service.

a. Install a manual shut-off gate valve in condensate

return line after steam trap for each coil.

b. Connect steam solenoid valve to related steam

INSTALLING STEAM TRAP AND MAKING
CONDENSATE RETURN CONNECTIONS

Steam trap must be installed and coil outlet
connections must be connected to condensate return
lines. The following steps outline the procedure for
installing steam trap and connecting condensate
return lines. See

a. Connect a flexible hose to each steam coil outlet,

Figure 24.

b. Install a strainer to the ends of each flexible hose.
c. Install a steam trap to each strainer.

IMPORTANT: Steam trap must be installed a
minimum of 10 inches (25.4 cm) below steam coil
outlet connections, see

d. Install a gate shut-off valve to each steam trap.
e. Connect to condensate return lines.

aWARNING
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
shutoff gate valve must be installed
downstream from each steam trap so
the condensate return line can be
isolated in event a steam trap requires
maintenance.

LIGHTING AND SHUTTING DOWN
GAS IGNITION SYSTEM

1. Turn machine disconnect switch, located on rear
of tumbler, to the “on” position.

2. Turn gas shut-off valve, located on rear of
tumbler, to the “on” position (gas valve handle
should be parallel with gas line).

3. Start tumbler, following operating instructions
which accompanied it.

NOTE: Ignition control circuitry will verify airflow
switch, located on rear of tumbler, is open before
starting cylinder motor. Once cylinder motor is
started, air flowing through tumbler will cause
airflow switch to close. Tumbler will purge air
from tumbler for 18 seconds. Ignition will start by
a three second release of gas from gas valve and
sparking of ignitor. If ignition does not occur

during first three seconds ignition control will
“lockout” causing gas valve to close and a red
button on ignition control to illuminate.

To reset ignition system , open access door and
press red button on ignition control. Close and
lock access door, verify that gas shut-off valve is
in the “on” position and return to step three.

4. If tumbler will not start, remove it from service by
turning machine disconnect switch, located on
rear of tumbler, to the “off” position and turn the
gas shut-off valve, located on rear of tumbler, to
the “off” position (gas valve handle should be at a
right angle to gas line).

SECTION III

Adjustments

MAIN GAS BURNER AIR SHUTTER
(All Gas Models)

NOTICE: Both air inlet shutters on burner must
be adjusted so sufficient air is metered into
system for proper combustion and maximum
efficiency. Before adjusting inlet shutters be sure
that all lint is removed from lint compartment and
lint screen.

Air shutter adjustments will vary from location to
location and will depend on vent system, number of
units installed, make-up air and line gas pressure.
Opening shutter increases amount of primary air
supplied to burner while closing shutter decreases
primary air supply. Adjust air shutter as follows:

1. Unlock and open access door.

2. Start tumbler and check flame pattern. Correct air
and gas mixture is indicated if flame pattern is
primarily blue, with small yellow tips, and bends to
right of heater section. (See
air is indicated if flame is yellow, lazy and smokey.

3. To adjust air shutter, loosen air inlet shutter
adjusting screw, see

4. Open or close air shutter as necessary to obtain
proper flame intensity.

5. After air shutter is adjusted for proper flame,
tighten air shutter adjusting screw securely.
Control panel may have to be removed
temporarily to loosen air shutter screws to turn
shutter.

AIR FLOW SWITCH
(Gas and Electric Models, see

Air flow switch is set at factory for proper operation.
Steam models do not have an air flow switch.
However, if there is a problem with airflow switch, it
should be adjusted as follows:

NOTICE: Control panel must be in place and
access door closed before attempting to adjust
air flow switch.

IMPORTANT: Air flow switch disc must remain
closed during operation. If it opens and closes
during drying cycle, this indicates insufficient air

Electric Models: If switch remains open, or pops
open and closed during cycle, heating system will
shut off. Cylinder and fan will continue to operate
even though air flow switch is malfunctioning.

Gas Models: If switch remains open, entire unit
will shut down when Push-to-start button is
released. Once tumbler starts and continues to
run, a loss of air flow, air flow switch jams or a
bouncing air flow switch will shut entire tumbler
down.

WARNING

維

To reduce the risk of fire, air flow
switch operation may be affected by a
clogged lint screen, lack of make-up
air, obstructions in the vertical
recirculation stack or in the customer
installed main or collector ducts.
These conditions must be checked
and necessary corrections made
before adjusting air flow switch.
Always adjust air flow at installation.

Air flow switch operation is controlled by counter­weight position on shaft. Moving counterweight either
increases or decreases air flow switch sensitivity.

Counterweight should be adjusted so air flow will
force disc away from cabinet when lint panel is
opened 6 inches (15.24 cm) with a full load. Adjust air
flow switch as follows:

1. Load tumbler.

NOTE: This adjustment is much faster to make
with one person opening lint panel in front and
another adjusting the counterweight in rear of
tumbler.

2. Start tumbler. Open lint panel 6 inches (15.24 cm).
Airflow disc should move away from cabinet,
opening switch contacts and shutting off heat
system. This indicates proper operation and
proper adjustment.

3. If switch is not opening as described in step “2”, it
should be adjusted so it is MORE sensitive.
Depress spring clip and move counterweight
toward disc. Retest by opening lint panel and
continue moving counterweight toward disc until
switch operates as described in step “2”.

4. If switch opens BEFORE lint panel is opened
proper distance, step “2”, it should be adjusted so
it is LESS sensitive. Depress spring clip and move
counterweight away from disc. Retest by opening
lint panel and continue moving counterweight
away from disc until switch operates as described
in step “2”.
