IMPORTANTINFORMATION
A. RECEIVINGAND HANDLING
The dryer is shipped in a protective stretch wrap cover with protective cardboard corners and top cover (or
optional box) as a means of preventing damage in transit. Upon delivery, the dryer and/or packaging, and
wooden skid should be visually inspected for shipping damage. If any damage whatsoever is noticed, inspect
further before delivering carrier leaves.
Dryers damaged in shipment:
1. ALL dryers should be inspected upon receipt and before they are signed for.
2. If there is suspected damage or actual damage, the trucker’s receipt should be so noted.
3. If the dryer is damaged beyond repair, it should be refused. Those dryers which were not damaged in a
damaged shipment should be accepted, but the number received and the number refused must be noted
on the receipt.
4. If you determine that the dryer was damaged after the trucker has left your location, you should call the
delivering carrier’s freight terminal immediately and file a claim. The freight company considers this
concealed damage. This type of freight claim is very difficult to get paid and becomes extremely difficult
when more than a day or two passes after the freight was delivered. It is your responsibility to file freight
claims. Dryer/parts damaged in transit cannot be claimed under warranty.
5. Freight claims are the responsibility of the consignee, and ALL claims must be filed at the receiving end.
ADC assumes no responsibility for freight claims or damages.
6. If you need assistance in handling the situation, please contact the ADC Traffic Manager at (508)
678-9000.

Installation should be performed by competent technicians in accordance with local and state codes. In the
absence of these codes, the installation mustconform to applicableAmerican National Standards:ANSI Z223.1-
LATEST EDITION (National Fuel Gas Code) orANSI/NFPA NO. 70-LATEST EDITION (National Electrical
Code) or in Canada, the installation must conform to applicable Canadian Standards: CAN/CGA-B149.1-M91
(Natural Gas) or CAN/CGA-B149.2-M91 (Liquid Propane [L.P.] Gas) or LATEST EDITION (for General
Installation and Gas Plumbing) or Canadian Electrical Codes Parts 1 & 2 CSAC22.1-1990 or LATEST EDITION
(for Electrical Connections).
A. UNPACKING/SETTING UP
Remove protective shipping material (i.e., plastic wrap, and/or optional shipping box) from dryer.
NOTE: Theaccesskeys for the service doorsareincludedintheinformation packet shipped in the
basket (tumbler). These keys shouldbe removedand put in a safeplace, yet made
accessiblebecause somewillbeneededthroughout various phasesintheinstallation ofthe
dryer.
Dryers are shipped with a coin box and coin box faceplate ONLY. The coin box lock is not included and
must be purchased elsewhere or the lock can be ordered as a parts order from the ADC Parts Department at
[phone].
The dryer can be moved to its final location while still attached to the skid or with the skid removed. To unskid
the dryer, locate and remove the four (4) bolts securing the base of the dryer to the wooden skid. Two (2) are
at the rear of the base and two (2) are located in the front. Once the bolts are removed, slide the dryer off of the
skid.
With the skid removed to make it easier to slide the dryer into its final position, slightly lower ALL the leveling
legs so that the dryer will slide on the legs instead of the base frame. The dryer is equipped with four (4) leveling
legs, one (1) at each corner of the dryer base. The hex head adjustment bolts for the two (2) front leveling legs
are located directly behind the lower access door and the rear two (2) adjustments are directly behind the lower
rear back guard panel.
1. Leveling The Dryer
To increase the bearing life, improve efficiency, and provide for better automatic closure of the main door,
the basket (tumbler) should be tilted slightly to the rear. Four (4) leveling legs are provided for this
purpose and are shipped inside of the top basket (tumbler) and must be installed at the time of installation.
A leveling leg must be screwed into the bottom of the dryer base at each corner area, where the bolts used
to secure the dryer to the wooded skid were removed.

9
B. LOCATION REQUIREMENTS
Before installing the dryer, be sure the location conforms to local codes and ordinances. In the absence of such
codes or ordinances the location must conform with the National Fuel Gas Code ANSI.Z223.1 LATEST
EDITION, or in Canada, the installation must conform to applicable Canadian Standards: CAN/CGA-B149.1-
M91 (Natural Gas) or CAN/CGA-B149.2-M91 (Liquid Propane [L.P.] Gas) or LATEST EDITION (for General
Installation and Gas Plumbing).
1. The dryer must be installed on a sound level floor capable of supporting its weight. Carpeting must be
removed from the floor area that the dryer is to rest on.
IMPORTANT: “Thedryermustbeinstalledonnoncombustible floorsonly.”
Even though a 12-inch (30.48 cm) clearance is acceptable, it is recommended that the rear of the dryer be
positioned approximately 2 feet (0.61 meters) away from the nearest obstruction (i.e., wall), for ease of
installation, maintenance, and service.
2. The dryer must not be installed or stored in an area where it will be exposed to water and/or weather.
3. The dryer is for use in noncombustible locations.
4. Provisions for adequate air supply must be provided as noted in this manual (refer to Fresh Air Supply
Requirements in Section D).
5. Clearance provisions mustbe made from combustible construction as noted in this manual (refer to Dryer
Enclosure Requirements in Section C).
6. Provisions must be made for adequate clearances for servicing and for operation as noted in this manual
(refer to Dryer Enclosure Requirements in Section C).
7. Dryer must be exhausted to the outdoors as noted in this manual (refer to Exhaust Requirements in
Section E).
8. Dryer must be located in an area where correct exhaust venting can be achieved as noted in this manual
(refer to Exhaust Requirements in Section E).
IMPORTANT: Dryershouldbelocated where a minimumamountofexhaustductwillbenecessary.

10
9. The dryer must be installed with a proper exhaust duct connection to the outside.
10. The dryer must be installed with provisions for adequate combustion and make-up air supply.
CAUTION: Thisdryerproducescombustiblelintandmustbeexhausted totheoutdoors. Every6

IMPORTANT: Dryermustbeinstalledina location/environment, whichtheambient
temperatureremainsbetween 40ºF (4.44º C)and 130º F(54.44º C).
C. DRYER ENCLOSURE REQUIREMENTS
Bulkheads and partitions should be made of noncombustible materials and should be located a minimum of
12-inches (30.48 cm) (18-inches [45.72 cm] or more is recommended for ease of installation, maintenance, and
service) above the dryer outer top, except along the front of the dryer which may be closed in if desired.
NOTE: Eventhoughaminimum of 12-inches (30.48 cm) above the dryer outer topisacceptable,a
clearanceof18-inches (45.72 cm) or more is suggestedforeaseofinstallationandservice
(electricalpowerconnections).
NOTE: Whenfire sprinkler systems arelocatedabovethedryers, a minimumof12-inches(30.48cm)
abovethedryer outer top is required.
NOTE: Allowancesmustbemadeforopeningthecontroldoor.
Dryers may be positioned sidewall to sidewall. However, allowances must be made for opening and closing of
the control door and the lint door. It is suggested that the dryer be positioned about 2 feet (0.61 meters) away
from the nearest obstruction for ease of installation, maintenance, and service (to be measured from the back
guard).
NOTE: Airconsiderations areimportantfor proper andefficientoperation.
D. FRESH AIR SUPPLYREQUIREMENTS
When the dryer is operating, it draws in room air, heats it, passes this air through the basket (tumbler), and
exhausts it out of the building. Therefore, the room air mustbecontinually replenished from the outdoors. If the
make-up air is inadequate, drying time and drying efficiency will be adversely affected. Ignition problems and
sail switch “fluttering” problems may result, as well as premature motor failure from overheating.
Air supply (make-up air) must be given careful consideration to assure proper and safe performance of each
dryer. An unrestricted source of air (550 cfm [15.58 cmm]) is necessary for each basket (tumbler). An
unrestricted air entrance from the outdoors (atmosphere) of a minimum of 2 square feet (0.19 square meters) is
required for each dryer. This area must be enlarged if louvers or registers cover the opening.
To compensate for the use of registers or louvers used over the openings, this make-up air must be increased by
approximately thirty-three percent (33%). Make-up air openings should not be located in an area directly near
where exhaust vents exit the building.

11
IMPORTANT: Make-upair mustbeprovided from a source freeofdrycleaningsolventfumes.
Make-upairthatiscontaminatedby drycleaningsolventfumeswillresultin
irreparabledamagetothemotors and other dryer components.
IMPORTANT: Make-upairopenings shouldnotbe located nearductwork exhaust outlets. If the
make-upairopening(s) are too closetotheexhaustoutlet,lint and fumes may be
drawnback into the dryerthroughtheseopenings.
NOTE: Componentfailuredueto drycleaningsolventfumeswillVOIDTHEWARRANTY.
It is not necessary to have a separate make-up air opening for each dryer. Common make-up air openings are
acceptable. However, they must be set up in such a manner that the make-up air is distributed equally to ALL
the dryers. The dryer must be installed with provisions for adequate combustion and make-up air supply.
EXAMPLE: For a bank of eight (8) dryers, a total make-up air opening of 16 square feet (1.49 square
meters) is required. Two (2) openings measuring 2 feet by 4 feet (0.61 meters by 1.23
meters) 16 square feet (1.49 square meters) is acceptable.
Allowances must be made for remote or constricting passageways or where dryers are located at excessive
altitudes or predominantly low pressure areas.

12
E. EXHAUST REQUIREMENTS
1. General Exhaust Ductwork Information
Exhaust ductwork shouldbe designed and installed by a qualified professional. Improperly sized ductwork
will create excessive back pressure which results in slow drying, increased use of energy, overheating of
the dryer, and shutdown of the burner by the airflow (sail) switches, burner hi-limits, or basket (tumbler)
hi-heat thermostats. The dryer must be installed with a proper exhaust duct connection to the outside.
CAUTION: DRYER MUSTBEEXHAUSTEDTOTHE OUTDOORS.
CAUTION: IMPROPERLYSIZEDORINSTALLEDEXHAUSTDUCTWORK CAN
CREATEAPOTENTIALFIREHAZARD.
IMPORTANT: Itisrecommendedthat exhaust or boosterfansnotbe used in the exhaust ductwork
system.
The exhaust ductwork should be laid out in such a way that the ductwork travels as directly as possible to
the outdoors with as few turns as possible. The shape of the ductwork is not critical so long as the minimum
cross-sectional area is provided.
It is suggested that the use of 90º turns be avoided; use 30º or 45º angles instead.
Theductwork shouldbe smooth insidewith noprojections from the sheet metalscrews or other obstructions,
which collect lint. When adding ducts, the ducts to be added should overlap the duct to which it is connected.
ALLductworkjoints mustbetaped topreventmoisture andlint from escapinginto the building. Additionally,
inspection doors should be installed at strategic points in the exhaust ductwork for periodic inspection and
cleaning.
IMPORTANT: Whenconnecting ductwork to the dryer’s top basket (tumbler) exhaust ductwork, be
surethatwhen screws are used they DO NOT restricttheoperation (both opening
andclosing) ofthedamper.
NOTE: Whenthe exhaust ductworkpassesthrough a wall,ceiling,orroof madeofcombustible
materials,theopeningmustbe2-inches(5.08cm)largerthantheduct(all the way around).
Theduct mustbecenteredwithinthisopening.
To protect the outside end of the horizontal ductwork from the weather, a 90º elbow bent downwardshould
be installed where the exhaust exits the building. If the exhaust ductwork travels vertically up through the
roof, it should be protected from the weather by using a 180º turn to point the opening downward. In
either case, allow at least twice the diameter of the duct between the duct opening and nearest obstruction.
IMPORTANT: DONOTusescreens, louvers, or caps on theoutside opening of the exhaust
ductwork.
NOTE: AspertheNationalFuelGasCode,“Exhaust ducts for type 2 clothes dryers shall be
constructedof sheetmetalor othernoncombustiblematerial. Suchducts shallbeequivalent in
strengthand corrosion resistance toductsmadeof galvanized sheetsteelnotlessthan
0.0195-inches(26gauge [0.05 mm]) thick.”

13
IMPORTANT: Exhaustbackpressuremeasuredbya manometer at the dryer exhaust duct area must
beno less than 0 and must notexceed0.3 inches (0.74 mb) of water column
(W.C.).
NOTE: Carefulconsiderationshouldbe giventowhere the exhaust duct islocatedinrelationtothe
make-upair openings. If make-upairopeningistoo close toexhaustoutlet,lint and fumes will
bedrawnbackintothedryerareathroughthese openings.
If the length of the ductwork run or quantity of elbows used exceeds the specifications noted in this booklet,
the cross-sectional area of the ductwork must be increased in proportion to the number of elbows or duct
run added.
IMPORTANT: Forextendedductworkruns,thecross-sectional area of the duct can only be
increasedto an extent. For extendedductworkruns,aprofessional heating, venting,
andair conditioning(HVAC)firmshouldbeconsulted forproperventing information.
Ductwork should be laid out in such a manner where allowances are made at the rear of the dryer for
removal of rear service panels/guards.
IMPORTANT: Eventhough the dryer’sexhaustoutletsize is 6-inches(15.24cm)in diameter (at both
thetopbasket[tumbler]damperductandthebottombasket[tumbler]elbowwhereit
leavesthedryer),the minimumconnectionatthepoint ofexitfromthedryer inALL
casesmustbe increased. Theamountofincreaseindiameterwilldependonthe
ventingapplication/layoutasdescribedfurtherinthismanual.
IMPORTANT: UNDERNOCIRCUMSTANCES can the dryer be vented to the outdoors using a
6-inch(15.24 cm) diameter exhaustduct!!!
2. Exhaust Connections of Top and Bottom Baskets (Tumblers)
There is no common venting connection provided with the dryer. Each basket (tumbler) exhaust duct is
provided with its own back draft damper. Each basket (tumbler) can be exhausted directly outdoors
independently (refer to the illustration on page 17) or connected commonly (“Y”) together (refer to the
illustration on page 18). Both single or common “Y” duct can be rigid or flexible ducting.

14
The exhaust connection at the top basket (tumbler) must be made at the blower duct inside the cabinet.
No internal ductwork is included for the top basket (tumbler) (not available from ADC and must be
purchased elsewhere). Depending on the external ductwork layout, the installer has the option of the
ductwork coming out of the top or the back of the dryer. The ductwork used inside of the dryer, from the
blower duct to where it exits the dryer, must be a minimum of 6-inches (15.24 cm) in diameter (30 square
inches [193.6 square centimeters] cross-sectional area). At this point, (where the internal ducting ends),
the diameter must be increased to meet the application as described further in this manual.
IMPORTANT: Whenconnecting ductwork to the top basket (tumbler) exhaust duct, be sure that
when screws areused they DONOTrestrict the operation (both openingand
closing)ofthedamper.
IMPORTANT: ALLductworkjointsmustbetapedtoprevent moisture and lintfromescapinginto
thedryerand/orbuilding.
The bottom basket (tumbler) includes a 6-inch (15.24 cm) ductwork, which extends from the dryer blower
duct to the lower back guard area. At this point, the diameter must be increased to meet the application as
described further in this manual.
The illustration below shows the ductwork connection points and what internal ductwork is included in
the dryer.

15
a. Connecting Both Top Baskets (Tumblers) and Bottom Baskets (Tumblers) Together
Both the top basket (tumbler) and the bottom basket (tumbler) can “Y” together to form one (1)
connection point. The bottom basket (tumbler) already includes a 6-inch (15.24 cm) diameter ducting
extending to the lower back guard area. The minimum connection at this point is 8-inches (20.32 cm).
The upper basket (tumbler) includes no internal ductwork (not provided by ADC, must be purchased
elsewhere, must be a minimum of 6-inches [15.24 cm], and only to the top of the dryer). At this point,
(where the internal ducting ends at top of the dryer), the diameter must be increased to meet the
application as described further in this manual.
IMPORTANT: When connecting ductwork tothetopbasket(tumbler)exhaustduct,besurethat
whenscrewsare used they DONOT restrict the operation (both openingand
closing)ofthedamper.
IMPORTANT: ALLductworkjointsmustbetaped to preventmoistureandlintfrom escaping into

3. Single DryerVenting
When possible, it is suggested that a separate exhaust duct be provided for each dryer. The exhaust
ductwork should be laid out in such a way that the ductwork travels as directly as possible to the outdoors
with as few turns as possible. It is suggested that the use of 90º turns be avoided; use 30º or 45º angles
instead. The shape of the exhaust ductwork is not critical so long as the minimum cross-sectional area is
provided.
IMPORTANT: Exhaust back pressuremeasured by a manometerat the dryer exhaustduct area must
beno less than 0 and must notexceed0.3 inches (0.74 mb) of water column
(W.C.).
If the length of the ductwork run or quantity of elbows used exceeds the specifications noted in this manual,
the cross-sectional area of the ductwork must be increased in proportion to the number of elbows or duct
run added.

IMPORTANT: UNDERNOCIRCUMSTANCES can the dryer be vented to the outdoors using a
6-inch(15.24 cm) diameter exhaustduct!!!
When independent exhaust ducting is used for each basket (tumbler), the connection size at the point
where the internal ducting (6-inch [15.24 cm] diameter) leaves the dryer, the minimum size connection
is 8-inches (20.32 cm) in diameter (54 square inches [348.4 square centimeters] cross-sectional area)
and this is only true providing: (Refer to the illustration on page 17 for details.)
1) The maximum duct run is no more than 15 feet (4.6 meters).
2) The ductwork is on a horizontal run (no riser).
3) There is no more than one (1) elbow, which includes the outside outlet (i.e., elbow used for outside
protection).
