the bottom of the upper heat module. The green and red wires are fed through the hole closest to the
doors and the high voltage wire gets put through the hole nearest the tumbler. The green wire has a ring
terminal that gets mounted to the burner assembly. The red and high voltage wires need to have the
provided connectors installed on the ends of the wires. Take stripped end of the wire and put it through the
end of the black cap, then, tighten the metal end clip. The red wire goes on the flame probe behind the
pilot line and the high voltage wire goes on the spark plug (spark plug closest to the front).
b. Burner Fan
The burner fan connections are made in the back of the burner fan motor. Remove the two (2) screws
that hold the cover to the junction box of the motor. The burner fan cable with the four (4) conductors in
it can be found next to the heat reclaimer piston. Connect the 90° end connector of the cable to the motor
junction box with the lock nut. After the cable is mechanically fastened to the motor begin to connect the
wires with the same color tape identifiers together. (CAUTION: There may be more than two [2]
connections at one junction) with wire and PVC electrical tape.
The green wire is ground and gets connected to the ground lug in the motor. Replace the two (2) screws
and the cover for the burner motor junction area.
14
c. Tumbler (Basket) Motors
The disconnects for the two (2) tumbler (basket) motors are located in the lower heat console. The right
drum (tumbler/basket) motor disconnect is located in the lower heat console on the upper shelf towards
the left. The left drum (tumbler/basket) motor disconnect is located in the base of the lower heat console
to the right. On both cables the mechanical connections should be made to the respective junction box.
Remove the two (2) screws that hold down the cover of each junction box. Insert cable end in the junction
box and fasten with lock nut. Then begin to connect the four (4) wires with the same color tape identifiers
together with the four (4) wires already in the junction box. Make these connections with wire nuts and
PVC electrical tape. Replace the cover and the cover (2) screws that hold down the cover to the junction
box.
d. Temperature Probe, Base, and Tumbler (Basket) Disconnects
The disconnects are located in the lower heat console. The temperature probe disconnect is located on
the upper shelf towards the left. The base disconnect and the tumbler (basket) disconnect are located on
the base towards the right. Check identifying tapes to ensure proper assignments of connectors to the
proper base. Check for proper keying and connect disconnect to the proper base. Engage hold downs on
base and verify that the clamps are properly locked.

D. EXTERNAL SUPPLY CONNECTIONS
1. Optional Sprinkler Water Supply
A 40 PSI (2.75 bar) supply of water must be connected into the 1” N.P.T. sprinkler connection located on
the left side of the tumbler (basket) base on dryer models with a sprinkler system.
2. Compressed Air Supply
A minimum of 20 cubic feet per hour (cfh) (.566 cu. m./hr) at 80 PSI (5.51 bar) of dry, clean and regulated
compressed air must be supplied to the dryer.
The compressed air supply must be connected into the 3/8” F.P.T. fitting which is located in the rear corner
of the lower heat console section.
19
3. Gas Piping
The gas connection to the dryer is made into the 2-inch F.P.T. shut-off valve located in the bottom front
corner of the lower heat console.
The gas pressure supplied to the dryer must be between 7-inches (17.41 m bar) and 13-inches (32.34 m
bar) water column (W.C.) for natural gas or between 10.5-inches (26.12 m bar) water column (W.C.) for
L.P. (liquid propane) gas.
If the facilities gas pressure is higher than these values, an external pressure regulator must be installed
prior to the dryer to reduce the gas pressure to within the appropriate range.
The dryer must be connected to either natural or L.P. (liquid propane) gas indicated on the dryer data label
located on the inner right wall of the electric cabinet. If your gas supply does not match the type of gas for
which the dryer was built, contact your distributor or the ADC factory.
1. The installation must conform with local codes or, in the absence of these local codes, with the National
Fuel Gas Code, ANSI Z223.1 or the CAN.CGA-B149, Installation Codes.
2. The dryer and it’s individual shutoff 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 psi (3.5 kPa.)
Pipe joint compounds that resist the action of natural and L.P. (liquid propane) gas must be used.
Test ALL pipe connections for leaks by brushing on a soapy water solution.
WARNING: NEVER TEST FOR LEAKS WITH A FLAME!!!
4. Exhaust Air Ducting
The dryer’s exhaust air must be vented to the outdoors by the shortest route possible with the number of
elbows kept to a minimum. The duct should be designed and installed by qualified technicians.
Improperly designed duct work reduce the airflow through the dryer, causing improper and unsafe drying
conditions. The static pressure of the air in the duct work must not exceed 1.25-inch water column
(3.1 millibar). The dryer exhaust 11,600 cfm (cubic feet per minute) - 328.5 cmm (cubic meters per
minute) - of air during the drying cycle, 13,000 cfm (cubic feet per minute) - 368 (cubic meters per minute) during cool down. Ducting must be sized for the 13,000 cfm 368 cmm (cubic feet per minute) of airflow.
The exhaust vent connection is located on top of the burner and heater section of the dryer. It has rectangle
cross-section and is flanged.
A sheet metal transition piece is supplied to connect a 24-inch (60.96 cm) diameter exhaust duct to the
dryers’ exhaust vent connection. Care must be taken in locating this transition piece so that the tilting
tumbler (basket) does not hit the transition piece.
The duct wire connecting the vent to the outdoors must be a minimum of 24-inches (60.96 cm) in diameter
for a round duct or 625 square inches (15.87 square meters) for a rectangular duct (22-inches by 22-inches
square duct [55.88 cm x 55.88 cm] would be sufficient).
20
The duct work must be smooth on the inside with no projections from sheet metal screws or other
obstructions which would collect lint. Inspection doors must be installed at strategic points in the duct work
for periodic lint removal.
Use smooth sweeping elbows instead of sharp 90º elbows. The radius of an elbow should be at least
1-1/2 times the duct diameter.
When the exhaust duct goes through a combustible wall on a roof, leave a 2-inch (5.08 cm) clearance space
between the exhaust ducting and the wall or roof.
When adding ducts, the duct that leaves the building must be protected from the weather. For horizontal
ducting use a 90º turned downward . For vertical duct work use a 180º turned downward. In either case,
allow at least twice the diameter of the duct between the duct opening and nearest obstruction. (If the duct
is rectangular, leave twice the smallest face dimension.)
IMPORTANT : DO NOT use screen or caps on the outside opening of the exhaust duct work.
Screens will clog with lint and caps will restrict the exhaust airflow.

or dedicated” single-phase (1ø) multi-wire branch circuit at dryer’s nameplate voltage.
NOTE: For 4-wire service, cap the neutral.
NOTE: Contact the factory for electrical information not listed.
NOTE: ADC reserves the right to make changes in specifications at any time, without notice or
obligation.
23
3. Electrical Service
The electrical power is connected the dryer at the high voltage section of the control cabinet. On the
ADG-464 dryer, this section is located at the bottom left of the main electrical enclosure.
The ADG-464 dryer must be supplied with two (2) independent input power lines. One is 3-phase ( 3ø)
electric service that feeds the dryer itself, and the other is 1ø electric service that feeds the safety sprinkler
system. Both input lines must be independent of each other and individually protected by their
individual fused disconnect.
NOTE: The ADG-464 with sprinkler option will not operate without an independent power source
fed to the Safety Sprinkler System.
Feed the electrical service cables to the dryer using the pre-punched knockouts at the bottom section of the
electrical cabinet right wall.
Connect the ground wires directly to the ground lug located at the same approximate area.
NOTE: The sprinkler operates off of single-phase (1ø) nameplate voltage of the dryer.
Before turning power on to the dryer, measure the supply voltage to ensure that it matches the dryer’s
specified input voltage. This input voltage is marked on the aluminum data plate located on the inner right
wall of the electrical cabinet.
24
F. FRESH AIR SUPPLY REQUIREMENTS
When the dryer is operating, it draws in room air, heats this air through the tumbler (basket), and exhausts it out
of the building. Therefore, the room air must be continually replenished from the outdoors. If makeup air is
inadequate, drying time and efficiency will be adversely affected, and safety will be compromised. Premature
component failure may result.
Air supply (make-up air) must be given careful consideration to assure proper performance of each dryer. An
unrestricted source of air is necessary for each dryer. An airflow of 13,000 cfm per minute (368 cmm) (cubic
meters per minute) must be supplied to each dryer. As a general rule, an unrestricted air entrance from the
outdoors (atmosphere) of a minimum twenty (20) square feet (6.096 m2) is required for each dryer.
To compensate for the use of registers or louvres used over the openings, the makeup air area must be increased
by approximately thirty-three percent (33%). Makeup air openings should not be located in an area directly
near where exhaust vents exit the building.
Allowances must be made for remote or constricting passageways or where dryers are located at excessive
altitude or predominantly low pressure areas. The dryer must be installed with provisions for adequate combustion
and make-up air supply.
IMPORTANT : Makeup air must be provided from a source free of dry cleaning solvent fumes.
Makeup air that is contaminated by dry cleaning solvent fumes will result in irreparable
damage to the motors and other dryer components.
NOTE: Component failure due to dry cleaning solvent fumes will VOID THE WARRANTY.
