14 American Dryer Corporation 113549- 7

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 (Propane Gas) or LATEST EDITION (for General Installation and Gas Plumbing).

The non-tilting model dryer requires 18-inches (45.72 cm) of space on each side of the dryer and 24-inches (60.96 cm) of space behind the unit for ease of service. A minimum of 12-inches (30.48 cm) must be allowed between the top of a gas dryer and the ceiling. A ceiling height of 120-inches (304.8 cm) is required for gas dryers, and a ceiling height for 130-inches (330.2 cm) is required for steam dryers. The dryer must be leveled for proper operation. If shimming is required, put metal shims, which are the same size as the base feet under the base feet. The dryer must be lagged to the floor.

WARNING: Dryer should be located where a minimum length of exhaust duct will be necessary .

1. The dryer must be installed with a proper exhaust duct connection to the outside.

2. The dryer must be installed with provisions for adequate combustion and make-up air supply .

CAUTION: This dryer produces combustible lint and must be exhausted to the outdoors. Every 6 months,

inspect the exhaust ducting and remove any lint build up.

IMPORTANT: Dryer must be installed in a location/environment, which the ambient temperature

remains between 40° F (4.44° C) and 130° F (54.44° C).

113549-7 www.adclaundry.com 15

C. FRESH AIR SUPPLY REQUIREMENTS

This appliance may only be installed in a room that meets the appropriate ventilation requirements specified in the national installation regulations.

When the dryer is operating, it draws in room air, heats it, passes this air through the tumbler , and exhausts it out of the building. Therefore, the room air must be continually 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 performance of each dryer. An unrestricted source of air is necessary for each dryer. An airflow of 5,300 cfm (cubic feet per minute) (150 cmm [cubic meters per minute]) must be supplied to each gas dryer and 6,500 cfm (184 cmm) for each steam dryer. As a general rule, an unrestricted air entrance from the outdoors (atmosphere) of a minimum of 6 square feet (0.56 square meters) is required for each gas dryer and a minimum of 8 square feet (0.74 square meters) for each steam dryer.

T o compensate for the use of registers or louvers used over the openings, this make-up air area 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.

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.

Allowances must be made for remote or constricting passageways or where dryers are located at excessive altitudes or predominantly low pressure areas.

IMPORTANT: Make-up air must be provided from a source free of dry cleaning solvent fumes. Make-up

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.

16 American Dryer Corporation 113549- 7

D. EXHAUST REQUIREMENTS

NOTE: For 1 door dryers, the 20-inch (50.8 cm) diameter exhaust duct exits from the rear of the base. For

2 door dryers, the 20-inch (50.8 cm) diameter exhaust duct exits from the left side of the base.

1. General Exhaust Ductwork Information

Exhaust ductwork should be 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 tumbler hi-limit thermostats. The dryer must be installed with a proper exhaust duct connection to the outside.

CAUTION: This dryer produces combustible lint and must be exhausted to the outdoors.

CAUTION: DRYER MUST BE EXHAUSTED T O THE OUTDOORS.

CAUTION: IMPROPERL Y SIZED OR INST ALLED EXHAUST DUCTWORK CAN CREA TE A

POTENTIAL FIRE HAZARD.

NOTE: THE DRYER MUST BE INDEPENDENTLY EXHAUSTED. COMMON DUCTWORK IS

NOT ACCEPTABLE.

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. Single or independent dryer venting is recommended.

The shape of the ductwork is not critical so long as the minimum cross section area is provided. It is suggested that the use of 90° turns in ducting be avoided; use 30° and/or 45° angles instead. The radius of the elbow should

preferably be 1-1/2 times the diameter of the duct.

ALL ductwork should be smooth inside with no projections from sheet metal screws or other obstructions,

which will collect lint. When adding ducts, the ducts to be added should overlap the duct to which it is connected. ALL ductwork joints must be taped to prevent moisture and lint from escaping into the building. Additionally, inspection doors should be installed at strategic points in the exhaust ductwork for periodic inspection and cleaning of lint from the ductwork.

IMPORTANT: Exhaust back pressure measured by a manometer/magnehelic in the exhaust duct must be

no less than 0 and must not exceed 0.3 in WC (0.74 mb).

NOTE: It is recommended that exhaust or booster fans not be used in the exhaust ductwork system except

where necessary to maintain exhaust back pressure (in the exhaust duct) between zero and 0.3 inch water column. Where employed, booster fans must not activate the dryer airflow proving switch (sail switch) when the dryer is not in operation.

113549-7 www.adclaundry.com 17

The internal dimensions of the dryer’s rectangular exhaust vent ductwork are 8-inches x 20-inches (20.3 cm x

50.8 cm). A transition piece 20-inches (50.8 cm) in diameter round is supplied. The location’ s exhaust duct must be the minimum exhaust size requirement of (20-inches [50.8 cm] round duct or 315 square inches [2,032 square centimeters] square duct) the ductwork from the dryer to the outside exhaust outlet for a horizontal run, with no more than one (1) elbow must not exceed 30 feet (9.14 meters) for gas and 20 feet (6.09 meters) for steam dryers. (Refer to the illustration below and on page 19.) For locations with more than one (1) elbow, the minimum exhaust size for a gas or steam model dryer is 24-inches (60.96 cm) round duct (464 square inches [2,993 square centimeters] duct) must be used.

a. The presence of condensate in the steam supply line will cause water hammer and subsequent heat exchanger

(steam coil) failure. The steam supply connection into the main supply line must be made within a minimum 10-inch (25.4 cm) riser. This will prevent any condensate from draining towards the dryer .

b. The steam supply line to the dryer must include a 12-inch (30.48 cm) riser along with a drip trap and check

valve. This will prevent any condensate from entering the steam coil.

c. Flexible hoses or couplings must be used. The dryer vibrates slightly when it runs and this will cause the

steam coil connections to crack if they are hard piped to the supply and return mains.

d. Shutoff valves for each dryer should be installed in the supply, return, and drip trap return lines. This will

allow the dryer to be isolated from the supply and return mains if the dryer needs maintenance work.

e. Install an inverted bucket steam trap and check valve for each unit at least 12-inches (30.48 cm) below steam

coil as close to the coil as possible.

f. The supply and return lines should be insulated. This will save energy and provide for safety of the operator

and maintenance personnel.

g. W ater pockets in the supply line, caused by low points, will provide wet steam to the coil possibly causing coil

damage.

ALL horizontal runs of steam supply piping should be pitched 1/4-inch (6.35 mm) for every 1 foot

(0.31 meters) back towards the steam supply header causing any condensate in the line to drain to the header. Install a bypass trap in any low point to eliminate wet steam.

5. Steam Damper System Operation

The steam damper, as shown in the illustration below, allows the coil to stay constantly charged eliminating repeated expansion and contraction. When the damper is opened, the air immediately passes through the already hot coil, providing instant heat to start the drying process. When the damper is closed, ambient air is drawn directly into the tumbler, allowing a rapid cool down.

Diagram 1 – shows the damper in the heating (open) mode, allowing heat into the tumbler .

Diagram 2 – shows the damper in the cool down (closed) mode, pulling ambient air directly into the tumbler without passing through the coils.

NOTE: With the dryer off or with no air supply , the damper is in the cool down mode as shown in Diagram

J. PREOPERATIONAL TEST

ALL dryers are thoroughly tested and inspected before leaving the factory . However , a preoperational test should be performed before the dryer is publicly used. It is possible that adjustments have changed in transit or due to marginal location (installation) conditions. Installer must instruct the user on how to correctly operate the dryer before leaving.

1. Turn on electric power to the dryer.

2. Make sure the loading doors are closed and the lint drawer is closed.

3. Make sure “green” power button is in and illuminated.

4. Microprocessor controller (computer) system operational test--to start the dryer:

a. Display will read “READY .”

b. Press “D” (preprogrammed) cycle key on the keypad.

5. The dryer will then start (i.e., blower, tumbler, and heat).

6. The light emitting diode (L.E.D.) display will read MANUAL DRYING CYCLE D, 00:00 MIN REMAIN.

NOTE: Press the “UP ARROW” to view the tumbler temperature at any time.

NOTE: The dryer can be stopped at any time by pressing the “STOP/CLEAR” key . If the temperature is

above the Cool Down set point when the “STOP/CLEAR” is pressed, the dryer will go into a Cool Down Cycle. If the “STOP/CLEAR” key is pressed again at this point the cycle that was in progress will be canceled and returned to the “READY” state. If the temperature is below the Cool Down set point the cycle that was in progress will be canceled, and go to W rinkle Guard.

7. When the programmed drying time has expired, the Phase 7 Non-Coin microprocessor controller (computer) will proceed into the Cool Down Cycle (mode).

8. Once the Cool Down Cycle begins at the end of the heat cycle the L.E.D. display will read COOL DOWN TEMP ___/___MINUTE REMAINING. At the end of the heat cycle, the dryer will shut off the heat, and continue the fan and tumbler until the Cool Down Time, or temperature is reached.

9. Once the Cool Down Cycle is completed the Phase 7 Non-Coin microprocessor controller (computer) will proceed into the Wrinkle Guard Cycle. The Audio Alert tone will sound for the amount set in Audio Alert ON Time. The L.E.D. display will read “WRINKLE GUARD.” The times are fixed at 2 minutes OFF, 2 minutes ON for a max time of 99 minutes. These times will start to rotate (without heat for 2 minutes). The Phase 7 Non-Coin microprocessor controller (computer) will repeat this process until the Maximum Wrinkle Guard On Time has expired (99 minutes). The L.E.D. display will then read “CYCLE DONE” and lockout the dryer functions until the doors are opened. It will then return to “READY.”

NOTE: Mechanical functions of the dryer is not allowed during the ON time. The blower (fan) must be

OFF to perform mechanical functions. However the “STOP/CLEAR” key may be pressed at any time to end the Wrinkle Guard cycle. Mechanical functions of the dryer is allowed during the OFF time.

38 American Dryer Corporation 113549- 7

NOTE: Dryer can be stopped at any time by opening the main door or by pressing the “CLEAR/STOP”

key . T o restart the dryer, press the “ENTER/ST AR T” key or a preprogrammed cycle key (i.e., “E”).

NOTE: Pressing keypad key “A,” “B,” “C,” “D,” or “F” will also start the dryer. The six preprogrammed

drying cycles (“A” thru “F”) have been stored in the microprocessor controller’s (computer’s) memory . Refer to the Programming Manual supplied with the dryer for these preprogrammed cycles.

10. Check to ensure that the tumbler starts in the clockwise direction. Additionally , check the direction of the blower motor to insure that it rotates in the counterclockwise direction as viewed from the left side of the dryer. If it does, the phasing is correct. If the phasing is incorrect, reverse two (2) of the leads at L1, L2, or L3 of the power supply connections made to the dryer.

IMPORTANT: Dryer blower motor and impellor/fan shaft as viewed from the left side of the dryer must

turn in the counterclockwise direction, otherwise the dryer efficiency will be drastically reduced, and premature component failure can result.

11. Heat Circuit Operational Test

a. Gas Models

1) When the dryer is first started (during initial start-up), the burner has a tendency not to ignite on the first attempt. This is because the gas supply piping is filled with air , so the dryer may have to be stopped and restarted several times for this air to be purged from the lines.

2) The dryer has one (1) burner box, which has its own Direct Spark Ignition (DSI) module and Spark Ignition/Flame-Probe Assembly. If ignition is not established after first attempt, the heat circuit DSI module will lockout until it is manually reset. T o reset the DSI system, open and close the loading doors and restart the dryer (press “ENTER/START” key).

NOTE: During the purging period, verify that ALL gas shutoff valves are open.

3) Once ignition is established, a gas pressure test should be taken at the gas valve pressure tap of the dryer to assure that the water column pressure is correct and consistent.

NOTE: W ater column pressure requirements (measured at both gas valve pressure taps)...

Natural Gas-----------------3.5 inches (8.7 mb) water column. Propane --------------------- 10.5 inches (26.1 mb) water column.

IMPORTANT: There is no regulator provided in a propane dryer. The water column pressure must be

regulated at the source (propane tank), or an external regulator must be added to each dryer .

b. Steam Models

SECTION VI

ROUTINE MAINTENANCE

A. CLEANING

A program and/or schedule should be established for periodic inspection, cleaning, and removal of lint from various areas of the dryer, as well as throughout the ductwork system. The frequency of cleaning can best be determined from experience at each location. Maximum operating efficiency is dependent upon proper air circulation. The accumulation of lint can restrict this airflow. If the guidelines in this section are met, an ADC dryer will provide many years of efficient, trouble free, and most importantly , safe operation.

WARNING: LINT FROM MOST F ABRICS IS HIGHL Y COMBUSTIBLE. THE

ACCUMULA TION OF LINT CAN CREA TE A POTENTIAL FIRE HAZARD.

WARNING: KEEP DRYER AREA CLEAR AND FREE FROM COMBUSTIBLE MA TERIALS,

GASOLINE, AND OTHER FLAMMABLE VAPORS AND LIQUIDS.

NOTE: Suggested time intervals shown are for average usage, which is considered six (6) to eight (8)

operational (running) hours per day .

IMPORTANT: Dryer produces combustible lint and must be exhausted to the outdoors. Every 6 months,

inspect the exhaust ducting and remove any lint build up.

SUGGESTED CLEANING SCHEDULE

EVERY THIRD OR FOURTH LOAD

Clean the lint basket. A clogged lint basket will cause poor dryer performance. The lint basket is located in the lint drawer in the base of the dryer. Pull out the lint drawer, brush the lint off the lint basket, and remove the lint. Inspect lint screen and replace if torn.

NOTE: Frequency can best be determined at each location.

WEEKLY

Open the hinged panels on each side of the tumbler section and remove any lint accumulation, from the tumbler drive motor, drive shafts, V-belts, drive wheels, and drive shaft bearings.

Slide the lint basket ALL the way out of the dryer and clean any lint accumulation off of the temperature sensor bracket, which is located above the lint basket.

W ARNING: TO AVOID THE HAZARD OF ELECTRICAL SHOCK, DISCONTINUE

ELECTRICAL SUPPLY T O THE DRYER.

113549-7 www.adclaundry.com 47

SECTION VII

COMPONENT SYSTEM DESCRIPTIONS

A. TUMBLER DRIVE SYSTEM

The tumbler is supported and driven by four (4) 11-inch diameter drive wheels. Two (2) of these wheels are attached to a 1-1/2” diameter idler shaft, while the other two (2) are attached to a 1-1/2” diameter drive shaft. Each of the wheels is fastened to the shafts by a taper lock bushing. The taper lock is made up of three (3) pieces: an inner collar, an outer sleeve, and a key . The inner and outer elements have matching opposing tapers. As a result, when the bolts are tightened, the taper lock contracts onto the shaft and expands into the drive wheel hub locking the wheel onto the shaft.

The idler shaft and drive shaft are each supported by two (2) 1-1/2” diameter pillow block bearings. These bearings sit on slotted support channels and can be moved inward or outward by the adjustment bolts to raise or lower the tumbler.

The drive system consists of a shaft mounted pulley , two (2) V-belts, and a 3 hp (2.24 kW) drive motor. Belt tension can be adjusted by tightening or loosening the gear reducer turnbuckle.

TUMBLER DRIVE SYSTEM

48 American Dryer Corporation 113549- 7

B. TUMBLER

The tumbler is made of 14-gauge stainless steel perforated panels, four (4) stainless steel ribs, and two (2) outer tumbler rings made of rolled steel angle iron that has been turned on a lathe for smoothness. The tumbler is a completely welded assembly , so the perforated panels

are not removable.

C. AIR BLOWER DRIVE SYSTEM

The impellor (fan) used in the dryer is a 15-inch diameter squirrel cage impellor (fan) wheel. It spins in a counterclockwise direction looking at the back of the blower housing.

The impellor (fan) shaft is mounted in two (2) pillow block bearings, and the shaft is driven by two (2) B-section V -belts connected to the blower motor.

The blower motor is mounted on an adjustable base. The motor position can be easily adjusted, so that proper tension can be maintained on the V-belts.

D. SAFETY DEVICES

1. Load/Unload Door Switches

There are two (2) of these switches located above the main loading doors. These switches ensure that the doors are closed before the dryer can start and ensures that the doors are fully open before the dryer will tilt. If the dryer is started when the load doors are open, the microprocessor controller (computer) light emitting diode (L.E.D.) display will show “front door not closed” or “rear door not closed” for 2 door dryers.

2. Lint Basket Switch

This switch ensures that the lint basket is closed before the dryer can start. This switch is located at the front of the dryer at the right side of the lint basket. If the lint basket is open when the dryer is started, the microprocessor controller (computer) L.E.D. will display “Lint Drawer Open” and will not reset until the lint drawer has been closed. For a “clean lint” prompt the lint drawer must remain open for 15-seconds.

3. Automatic Reset Tumbler Hi-Limit Safety Thermostat

The automatic reset tumbler hi-limit switch is a thermostat type switch located above the lint basket. Its function is to discontinue heat (flame) in the event of an over temperature situation (above 225° F [107° C]). This will shut off the gas flow to the burner boxes; and the display will read an error code of “tumbler hi-limit fault.” The automatic reset hi-limit safety will automatically reset once the temperature has fallen below 225° F (107° C). The Phase 7 computer must be reset by pressing the Stop key, then the display will read “READY.”

113549-7 www.adclaundry.com 49

4. Manual Reset Burner Hi-Limit Safety Thermostats (for Gas Dryers Only)

These disk temperature switches have a setting of 330° F (166° C). They are located on the right side of each burner box, and they are a manual reset type of switch. These switches ensure that there is a proper airflow through the burner box. Upon a low airflow condition, which may be caused by a clogged lint screen excessively long or blocked exhaust duct, or improper make-up air, the temperature in the burner boxes will increase tripping these switches. This will shut off the gas flow to the burner boxes; and the display will read an error code of “Burner Hi-Limit Fault.” The thermostat must be manually reset and the Phase 7 computer must be reset.

5. Sail Switch (for Gas Dryers Only)

The sail switch is located in the front of the burner box. A sail switch consists of a round damper plate on a lever arm, which is in contact with an electric switch. When the air blower comes on, it draws air through the gas burner. This creates a negative pressure inside the burner box. This negative pressure pulls in the sail switch. If the sail switch does not pull in, this will prevent the dryer from operating and a sail switch fault will display .

NOTE: An overly long or blocked exhaust duct, lack of make-up air, or clogged lint screen will prevent the

sail switches from pulling in.

50 American Dryer Corporation 113549- 7

E. STEAM DAMPER ACTUATOR SYSTEM

The system consists of a hinged damper plate, a pneumatic piston (with an airflow needle valve) to control the speed of the piston actuation, and a 24 volt solenoid valve.

On a call for heat, a 24 volt signal is applied to the 3-way/2-position solenoid valve. This signal switches the valve so that compressed air is sent to the piston. The piston rod extends, pushing the hinged steam damper plate to the opened position. This allows room air to be drawn through the hot steam coil and then through the tumbler .

When the temperature set point has been reached, the 24 volt signal is removed from the solenoid valve, so that the solenoid valve blocks the air supply to the pistons, and the air in the pistons is bled to the atmosphere. The springs in the pistons now retract the piston rods, closing the steam damper. The steam damper plate now covers the steam coil and allows room air to bypass the coil before entering the tumbler for a rapid cool down.

The steam damper plate should open and close slowly and smoothly. The speed can be modulated by adjusting both needle valve knobs. Turning the knob clockwise restricts the compressed airflow and slows down the steam damper movement. Counterclockwise adjustment speeds up the steam damper motion. Upon completion of adjustment, tighten the needle valve’s locking nut.

NOTE: Turning knob on flow control clockwise will restrict airflow . Turning knob counterclockwise will

allow higher airflow .

SECTION VIII

MANUAL RESET BURNER HI-LIMIT INSTRUCTIONS

I M P O R T A N T

MANUAL RESET HI-LIMIT INSTRUCTIONS

FOR PHASE 7 MODELS

This dryer was manufactured with a manual reset burner hi-limit, which is monitored by the Phase 7 computer. If the burner is open prior to start of the drying cycle, the dryer will start momentarily and then shutdown, the Phase 7 computer will display “burner HIGH LIMIT fault” with an audio indication.

If the burner hi-limit thermostat opens during a drying cycle, the Phase 7 computer will also display the same error code described above, along with an audio indication. If the drum temperature is above 100° F (38° C), the dryer will continue to run with no heat for 3 minutes or until the drum temperature has dropped below 100° F (38° C). The clear/ stop button on the Phase 7 keypad must be pressed to clear the error condition. The open manual reset hi-limit thermostat must be reset “manually” prior to the start of the next cycle.

This hi-temperature condition may be caused due to a restricted exhaust, poor airflow , or improper burner operation.

The location of the burner hi-limit is on the right side of the burner box, looking at the burner from the back of the dryer.

WARNING: Discontinue power to dryer before attempting to reset hi-limit.

PROCEDURE FOR FUNCTIONAL CHECK

OF REPLACEMENT COMPONENTS

1. For Models with Direct Spark Ignition (DSI) Module (T ype I)

Theory of Operation:

Start the drying cycle. When the gas burner ignites within the chosen trial for ignition time (6-seconds), the flame sensor detects gas burner flame and signals the DSI module to keep the gas valve open as long as there is a call for heat. The DSI module will “LOCKOUT” if the gas burner flame is not sensed at the end of the trial for ignition period. The trial for ignition period will be repeated for a total of three (3) retries/ trials (the initial try and two [2] more retries/trials). If the flame is not sensed at the end of the third retry/trial (inter-purge period of 30-seconds) the DSI module will “LOCKOUT” (light emitting diode [L.E.D.] diagnostic indicator flashes).

A steady L.E.D. indicator indicates normal operation.

No L.E.D. indicator indicates a power or an internal failure has occurred.

2. For Models with DSI Module (Type II)

Theory of Operation:

Start the drying cycle. When the gas burner ignites within the chosen trial for ignition time (8-seconds), the flame sensor detects gas burner flame and signals the DSI module to keep the gas valve open as long as there is a call for heat. The DSI module will “LOCK OUT” if the gas burner flame is not sensed at the end of the trial for ignition period. The trial for ignition period will be repeated for a total of three (3) retries/ trials (the initial try and two [2] more retries/trials). If the flame is not sensed at the end of the third retry/trial (inter-purge period of 30-seconds), the DSI module will “LOCK OUT” (a red L.E.D. diagnostic indicator will flash).

An unlit red L.E.D. diagnostic indicator indicates normal operation.

A lit green L.E.D. diagnostic indicator indicates dryer controller is calling for heat and that ALL interlocks have been satisfied.

OPTIONAL SENSOR ACTIVATED

FIRE EXTINGUISHING (S.A.F .E.) SYSTEM

S.A.F.E. SYSTEM IN ACTION

The exclusive Sensor Activated Fire Extinguishing (S.A.F.E.) System will extinguish fires that may start in the drying tumbler. A series of sensors positioned throughout the tumbler and interfaced with the microprocessor will trigger the S.A.F.E. system water jet(s) to quickly extinguish the flames. The water jet(s) remain on for 2 minutes and will automatically activate again if a fire condition remains or reignites. While the water jet(s) are activated, the tumbler will jog to move the water throughout the load. The microprocessor will display that the system was activated and will continue to display until the dryer is attended to.

W e have tried to make this manual as complete as possible and hope you will find it useful. ADC reserves the right to make changes from time to time, without notice or obligation, in prices, specifications, colors, and material, and to change or discontinue models.

S.A.F.E. SYSTEM THEORY OF OPERATION

While the dryer is in an idle state or 20-seconds after the heat turns off, the Phase 7 control monitors the S.A.F.E. system probe located in the top of the tumbler chamber and records the minimum temperature. If the minimum recorded S.A.F.E. system probe temperature is no less than 120° F (48° C) and the control detects a 50° rise in temperature, this

While a drying cycle is in process and the heat has turned on at least once, the Phase 7 control monitors the exhaust temperature transducer. If the drying cycle temperature set point is set greater than 160° F (71° C) and the control detects an exhaust temperature rise 25° F greater than set point, this will be the trip point and the S.A.F.E. system routine will activate. If set point is below 160° F (71° C) the trip point will be 185° F (85° C).

will be the trip point and the S.A.F.E. system routine will activate.

Once the S.A.F.E. system routine is activated, water being injected into the tumbler; the tumbler drive will turn the load for 1-second every 15-seconds. This process will continue for a minimum of 2 minutes. After 2 minutes has elapsed, the control will check if the temperature remained above trip point, if so water will remain on. The control will continue to check if temperature is above trip point every 30-seconds. If the water has been on for a constant 10 minutes, the water temperature. If the temperature has dropped below trip point, the control will turn off the water prior to 10 minutes.
