Installation Procedures __________________
Location Requirements
The temperature of the installation location must remain
between 4° C and 55° C.
The dryer must not be installed or stored in an area where it
will be exposed to water and/or weather.
The dryer should be located where a minimum amount of
exhaust ducting will be necessary.
The dryer must be installed on a sound level floor capable of
supporting its weight. Any carpeting must be removed.
Install a lockable door to prevent the public from accessing the
rear of the dryer.
The appliance must not be installed behind a lockable door, a
sliding door or a door with a hinge on the opposite side to that
of the tumble dryer, in such a way that a full opening of the
tumble dryer door is restricted.
Unpacking / Setting Up
Dryer must be handled in an upright position at all times.
Remove protective shipping material (i.e. plastic wrap and
optional shipping box) from the dryer.
Remove the pallet. Remove the 4 bolts securing the base of
the dryer to the pallet (one in each corner of the cabinet base).
Remove the back guard for access to the 2 rear bolts. Remove
the lint door or drawer to reach the 2 front bolts.
If the dryer is to be slid into its final position, ensure that all four
leveling legs (one in each corner) are extended slightly so the
dryer will slide on these legs (not the cabinet frame).
Once the dryer is in position, adjust the leveling legs so it is
level side-to-side. To increase bearing life and improve
efficiency, the dryer should be tilted slightly to the rear.
Dryer Enclosure Requirements
Clearance to combustible material
A Minimum 30 cm (46 cm recommended)
B Minimum 30 cm (61 cm recommended)
C Minimum 5 cm
D Minimum 10 cm
E Maximum 10 cm
Clearance to nearest obstacle
F Open Door:
AD-25V, AD-30V, AD-50V: 76 cm, AD-758V: 102 cm
G 2.5 cm (To allow control door to open)
H 2.5 cm
I 1.5 mm
J 1.5 mm
Fresh (Make-Up) Air Supply
Requirements
The dryer draws in air, heats it, passes it through
the tumbler, and exhausts it outside.
Adequate ventilation has to be provided to avoid the back flow
of gases into the room from appliances burning fuels, including
open fires.
Insufficient fresh air supply could diminish dryer performance.
Make-up air must be free of dry cleaning solvent fumes.
Locate fresh air openings away from exhaust vent discharge.
Locate the openings behind the dryer to avoid room drafts.
2
An unrestricted opening to the outdoors of 500 cm
AD-25V, 610 cm2 for each AD-30V, 970 cm2 for each AD-50V
and 1,130 cm2 for each AD-758V is required (Based on 22 cm
per kW).
Separate make-up air openings are not required. Common
openings, located evenly between the dryers, are acceptable.
The size of the make-up air opening must be increased by
33% to compensate for the use of registers or louvers.
for each
Exhaust Requirements
Single (independent) dryer venting is recommended.
Dryers must be exhausted to the outdoors.
The dryer shall not be exhausted into any gas vent, chimney,
wall, ceiling, or concealed space of a building.
Exhaust ductwork should be designed and installed by a
qualified professional. Improperly sized ducting will result in
slow drying and possible dryer malfunction.
Exhaust back pressure should be a minimum of 0 mb and a
maximum of 0.75 mb (1.75 mb for 758V).
The design of the flue system shall be such that any condensate
formed when operating the appliance from cold shall either be
retained and subsequently re-evaporated or discharged.
Use metal ducting or other noncombustible material.
Avoid 90° turns; use gentle (30° or 45°) bends instead.
Elbow radius should be at least 1.5 times the duct diameter.
Avoid using screws or other fasteners that project into the
exhaust airflow and collect lint.
There must be 5 cm of clearance if the duct passes through
any wall, ceiling, or roof made of combustible materials.
Protect the end of the exhaust duct from the weather outside.

Steam Information ______________
Steam installation should be performed by
qualified personnel in accordance with national
and local safety regulations.
Care must be taken when leveling a steam dryer to promote
good steam coil drainage. Return lines should be level or
pitched down slightly for good drainage.
The steam supply to the coil must be from the top of a welldripped steam main. If the supply run-out to the dryer exceeds
6 meters then it should be dripped just before the control valve
with a proper trap and dirt pocket.
The normal pH level for copper-type steam coils must be
maintained between 8.5 and 9.5. For steel-type steam coils
the pH level must be between 9.5 to 10.5. These limits are
required to limit the acid attack of the steam coils.
Properly sized steam supply, and return, lines are required to
avoid poor performance.
Clean, dry steam must be provided to the dryer.
The steam supply connection into the main supply line must
be made with a minimum 25 cm riser. This will prevent any
condensate from draining towards the dryer.
The steam supply line to the dryer must include a 30 cm riser
along with a drip trap and check valve. This will prevent any
condensate from entering the steam coil.
Flexible hoses or couplings must be used. The dryer vibrates
slightly when operating which could cause steam connections
to crack if they are hard piped.
Horizontal sections of steam supply piping should be pitched
back towards the steam supply header (minimum slope of 1
cm for every meter) to allow any condensation to flow back
into the header. Install a bypass trap in any low point to eliminate
wet steam.
Failure to comply with the above requirements can result in
water hammer, premature component failure, and will void the
warranty.
12 American Dryer Corp. 113686-1
Steam Supply Requirements
Maximum Pressure 862 kPa
Minimum Pressure 689 kPa
Shutoff valves for each dryer should be installed in the supply
line, return line, and drip trap return line. This will allow the
dryer to be isolated from the steam supply if the dryer will be
serviced.
The supply and return lines should be insulated to save energy
and provide safety to maintenance personnel.
Pneumatic Steam Damper Arrangement
(Refer to figure)
A clean and dry compressed air supply (A) (5.5 bar ± 0.7 bar )
is required for dryers with a pneumatic piston (B) and damper
(C) arrangement.
The air connection is made to the steam damper solenoid valve
(D), which is located at the rear inner top area of the dryer just
in front of the rear electric service relay box (E).
Damper operation was calibrated prior to shipping. Airflow to
the piston (B) can be regulated by adjusting the flow control
valve (F). Turn the knob (G) clockwise to reduce airflow. Turn
the knob (G) counterclockwise to increase airflow.

Steam Damper System Operation
(Refer to the figure)
The steam damper arrangement allows the coil to be charged
continuously (eliminates repeated expansion and contraction).
During the heat cycle the damper (C) is in the open position.
Air (H) is heated as it passes through the hot coil (J) and into
the tumbler during the drying process.
During the cooldown cycle the damper (C) is in the closed
position. Air (H) will bypass the hot coil (J) and the cool air will
enter the tumbler during the cooldown phase.

Start-Up ___________________________________
Check:
• Gas dryers – All shutoff valves should be open.
• All back panels (guards) should be in position.
• Service doors should be securely closed.
• Lint door or drawer should be fully closed.
• The tumbler (drum) should rotate freely.
Tumbler Coating
The tumbler has a protective coating that should be wiped clean
with water and mild detergent solution (nonflammable).
Alternatively, tumble a load of old garments that are wetted
with water and mild detergent solution (nonflammable).
Preoperational Test
A performance check is needed after the dryer is fully installed
and before the dryer is ready for use.
Start the dryer (refer to the Operating Instructions below).
Gas heat – Check for flame ignition (may need more than one
attempt to purge air from the gas supply pipe).
Electric heat – Check the contactor(s) are cycling the electric
oven (heater) properly.
Steam heat – Check the damper (or steam solenoid valve, if
equipped) is functioning properly. Dampers should not bind or
slam during operation. If the damper motion is not smooth
and quiet then the flow control must be adjusted.
Water Information _______________
(If dryer is equipped with F.S.S.)
Water installation should be performed by qualified
personnel in accordance with national and local safety
regulations.
If the water system activates then you must have the dryer
inspected by a qualified agency. Do not operate the dryer.
Electric power to the dryer must be on at all times in order for
the fire suppression system (F.S.S.) to function.
The water connection is made into the rear of the dryer (refer
to the Technical Specifications page).
Use a new hose to connect to the water supply.
A flexible supply line, with coupling, must be used to avoid
damaging the water solenoid valve.
Water supply pipe size should be at least 1/2-inch (nominal)
(21.3 mm) and the supply pressure should be 275 ± 137 kPa.
Protect water lines from freezing if they will be exposed to
freezing-cold temperatures.
Safety Related Circuits
The dryer should stop when the main door is opened.
The dryer should stop when the lint door is opened.
If any failed test cannot be corrected, or if other concerns are
detected, contact your local service organization or dealer.
Ready for Use
If all tests are acceptable then the machine is ready for use.
Installer must instruct the end user on how to operate the dryer
before leaving.

Routine Maintenance _____________________
A schedule should be established for the periodic inspection,
cleaning, and lint removal. The frequency of cleaning can best
be determined from experience at each location. Ideal drying
performance depends on sufficient airflow. Lint accumulation
can restrict airflow and is also a fire hazard.
Avoid using harsh chemicals when cleaning the dryer.
Suggested Cleaning Schedule
(Based on approximately 6-8 hours of daily operation)
To avoid electric shock and contacting
moving parts, discontinue electrical
supply any time a panel (without an
interlock switch) or guard is removed.
Every Three or Four Loads
Clean the lint screen – located behind the lint door (lower front
panel). The 50V and 758V have a lint drawer that slides out for
cleaning. Replace the lint screen if it is torn or damaged.
Weekly
Clean lint accumulation from the lint chamber, thermostat and
operating temperature sensor (located just below the drum).
Steam dryers: carefully clean steam coil fins (which are easily
damaged). We suggest using a vacuum cleaner with brush
attachment. Straighten bent fins with a fin comb.
