SECTION I

INTRODUCTION

The Phase 3 computerized system is a fully programmable, highly sophisticated dryer control system. ADC has designed the Phase 3 to be the most versatile and reliable coin-op control system available.

To eliminate as many moving parts as possible, switch on the front of the control panel. The switch (PS) that puts the computer into the program mode is a single, sealed, military specification toggle switch. This toggle switch (PS) eliminates the possibility of switch failure due to an accumulation of lint or moisture.

ALL Phase 3 programming is done through the membrane

PHASE 3 FEATURES

Programmable

Changes in programs are made at the temperature selection keyboard (touch pad), and actual programs are displayed for verification.

Adjustable Time

Programmable from a minimum of 1 minute to a maximum of 99 minutes in 1 minute increments.

Coin Acceptor Denominations

Values of the coin acceptors are programmable from a minimum of 1 to a maximum value of 9999 for any U.S. or foreign coin denomination.

Amount To Start

Programmable from a minimum value of 1 to a maximum value of 9999 in increments of one (1).

Accumulative Time

This program yields a specific value of time for any coin entry made after the “Amount To Start” has been inserted.

Accumulative Coin

This program selection requires that a specific value of coin(s) be inserted for additional time, programmable for any minimum amount.

Coin Count

The number of coins inserted, including a separate display program for optional dual coin acceptors, can be viewed through the Phase 3 computer’s light emitting diode (L.E.D.) display.

Bad Coin Lockout

Each coin entry is monitored. Should someone tamper with the coin acceptor or attempt to insert a foreign object, the microprocessor controller (computer) will “LOCK UP” and will not accept any entries until the reset time has elapsed (approximately 15-seconds). Once the reset time has expired, the microprocessor controller (computer) will automatically reset itself for the next coin entry.

Temperature Conversion

When the temperature conversion status is changed (i.e., from ºF to ºC), the microprocessor controller (computer) will automatically convert ALL temperature related programs/parameters from Fahrenheit to Celsius and vice versa. The microprocessor controller (computer) will perform this conversion within 2º Celsius. The programs affected are:

1. Temperature Display Mode

2. Temperature Selections

3. Cool Down Temperatures

Drying Temperatures

Any of the three (3) temperature selections (HI/LO/PP) are programmable from a minimum of 100º F (38º C) to a maximum of 190º F (88º C) in ten-degree increments or from a minimum 35º C (95º F) to a maximum of 90º C (194º F) in five-degree increments. Actual temperature programs are displayed at time of programming for verification.

Cool Down Time

ALL three (3) temperature selections are programmable from a minimum of 0 to a maximum of 9 minutes in 1

minute increments.

Cool Down Temperatures

In the automatic or free dry modes, the cool down cycle termination is programmable from a minimum of 100º F (38º C) to a maximum of 190º F (88º C) in ten-degree increments or, from a minimum of 35º C (95º F) to a maximum of 90º C (194º F) in five-degree increments.

Automatic Mode

This program will cycle the dryer off when the preprogrammed dryness level (1 to 99) or maximum cutoff time (Adrt) (1 to 99 minutes) has been reached, whichever comes first.

Antiwrinkle

This program selection helps keep permanent press items wrinkle free, when they are not removed from the dryer promptly at the end of the drying and cooling cycle. The owner programs the dryer to automatically restart in the cool down cycle, if the clothes Program settings are:

1. Guard Delay Time---------- 1 to 9 minutes

2. Guard On Time ------------- 1 to 99-seconds

3. Active Guard Time --------- 1 to 99 minutes

are not removed in a preprogrammed amount of time. The Antiwrinkle

Free Dry Mode

In this program mode, the computer automatically reverts to the automatic mode. However, no coins are required to start the dryer.

Light Emitting Diode (L.E.D.) Flash Display

Programmable to allow the L.E.D. readout to display a choice of “FILL” (no cycle in progress), “Amount To Start” (i.e., 25¢), or in the case of free dry, “FrEE.” This program selection also allows the L.E.D. display to flash back and forth every 2-seconds from “FILL” to “Amount To Start” or, in the case of free dry, from “FILL” to “FrEE.”

Audible Tone

In this program selection, a buzzer (tone) will sound for each coin inserted, program entry, or at the end of the drying cycle and cooling cycle for a period of 5-seconds to indicate that the cycle is complete. Additionally, when in the Antiwrinkle program, the buzzer (tone) will sound for 5-seconds at the end of the “Guard On Time.”

Temperature Display

This program selection enables the temperature in the dryer to be viewed (ºF or ºC) either while the dryer is off or running. This service feature shows that the dryer is maintaining the selected temperature.

Diagnostics

ALL major circuits, including door, microprocessor temperature sensor, heat, and motor circuits are monitored.

Battery Backup (Optional)

This feature allows the microprocessor controller (computer) to maintain its operating status should a momentary power interruption occur while the dryer cycle is in progress.

SECTION II

INSTALLATION PROCEDURES

A. INSTALLATION

The dryer is mounted on a skid by four (4) bolts. The front two (2) bolts are located on the floor of the lint compartment. The other two (2) are located on the base at the rear of the dryer.

NOTE: Always keep the dryer in an upright position.

B. LOCATION OF THE DRYER

Approximately 2 feet (0.609 meters) should be allowed at the rear of the dryer for the duct and for ease of maintenance. The dryer should be level. The four (4) legs are adjustable. (Refer to the illustration below for details). Other factors to keep in mind include the following:

1. The main duct of the dryer must be tapered.

2. The minimum increase in cross section area for each 6-inch (15.24 cm) duct added is 45 square inches (290.32 square centimeters) and 75 square inches (483.87 square centimeters) for each 8-inch (20.32 cm) duct added.

3. Ducts should enter the main duct at the bottom or on the side at no more than a 45º angle.

4. Each exhaust duct should enter the main duct at least 34-inches (86.36 cm) apart.

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

6. 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.

C. DRYER ENCLOSURE

Bulkheads and partitions should be made of noncombustible materials.

D. AIR INTAKE

Make-up air will effect drying time, efficiency, and fire safety margins. Make-up air openings from an outside source should be two (2) to three (3) times the cross section area of the exhaust on gas and electric dryers, and four (4) to five (5) times the area for steam dryers. The dryer must be installed with provisions for adequate combustion and make-up air supply.

E. EXHAUST DUCTING

Whenever possible, exhaust each dryer separately. Never reduce the air outlet diameter of the dryer.

Avoid 90º right angle turns in the ducting. Where turns are necessary, use 45º or 30º angles instead.

Avoid any screw or object that would protrude inside the exhaust duct and create a lint build up.

DO NOT use screws or caps on exhaust.

If the exhaust duct goes through the roof, it may be protected from the weather by using a 180º turn to point the opening downward. If it goes through the wall, use a 90º turn to point the opening downward. (Refer to the

illustration below.) 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.

F. COMMON MAIN DUCT

When individual exhaust is impossible, a common main duct may be used. However, strict attention must be given to the construction of the duct to insure proper exhaust and to prevent restrictions in the airflow. (Refer to the illustrations below.)

G. ELECTRIC DRYERS

Insure that the power supply is sufficient to operate the dryer. Low voltage and amperage will cause poor drying, overheated motors, poor relay function, and reduced fire safety margins.

Electrical connections should only be made by qualified personnel.

NOTE: Only copper cable of proper size should be used on these dryers. The use of aluminum wire

VOIDS THE WARRANTY.

H. GAS DRYERS

ALL dryers are provided with 1/2” gas lines. Consult your local gas supplier for correct line size and pressure. The built in regulator provides 3.5 inches (8.7 mb) water column (W.C.) at the manifold for natural gas. Liquid propane (L.P.) gas must be regulated in line by the supplier to 10.5 inches (26.1 mb) water column. A shutoff valve should be installed at the rear of the dryer for easy servicing and safety. Gas connections should only be made by qualified personnel.

I. GAS FLAME ADJUSTMENT

Dryers are equipped at the factory with the correct orifice and are adjusted for proper performance. Should further adjustment be needed, rotate the air adjustment plate until yellow flame is at a minimum.

IMPORTANT: Test ALL connections for gas leaks by brushing on a soapy solution (liquid detergent

works well).

WARNING: NEVER TEST FOR GAS LEAKS WITH A FLAME!!!

J. STEAM DRYERS (LOW-PRESSURE)

Low-pressure steam (10-15 psig [0.69-1.03 bars]) has a minimum push through the systems, therefore, the following is recommended for 3 to 7 dryers:

1. 3” main steam line

2. 2” return line

3. 1” line from main line to each dryer

4. 1” line from dryer to return lines

Piping should be installed with good commercial steam system practices. (Refer to the illustration below.)

An impulse trap and filter should be installed at each dryer. After 1 or 2 days of operation, the following maintenance should be performed:

1. Pressure should be 10-15 psig (0.69-1.03 bars).

2. Filter and traps should be clean and operational.

3. There should be proper flow of steam and condensate.

4. There should be sufficient make-up air to the heat exchanger.

5. The dryer should be properly exhausted.

K. STEAM DRYERS (HIGH-PRESSURE)

A high-pressure steam dryer is similar to a low-pressure one, but has a 125 psig (8.6 bars) maximum. Maintenance is the same. Each coil is supplied by a 1” inlet and the outlet is a 1-2” line.

L. BASKET (TUMBLER)

The basket (tumbler) is adjusted at the factory. However, handling in shipment could cause misalignment. If adjustment is necessary, follow the instructions in the service manual.

BASKET (TUMBLER) COATING

The basket (tumbler) is treated with a protective coating. We suggest dampening old garments or cloth material with a solution of water and nonflammable mild detergent and tumbling them in the basket (tumbler) to remove this coating.

M. GROUNDING

Computer dryers should be individually grounded. A copper or brass stake driven into the ground is the best grounding method.

The dryer and its 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 psig (3.5 kPa).

The dryer must be isolated from the gas supply piping system by closing its individual manual shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psig (3.5 kPa).

PROGRAM SELECTIONS

NOTE: Programs are stored in the computer memory and are cataloged as program locations (PL).

Temperature Display Mode

By closing the Program Switch (PS), the display will read the temperature in the dryer in either Fahrenheit or Celsius, depending on how the PL01 temperature conversion status is set. The temperature display mode can be activated while the dryer is in the operating cycle or off. While in the operating cycle, the circuit indicators are visible for troubleshooting purposes.

NOTE: The dryer cannot be started while the computer program switch (PS) is closed unless the

cycle was already in progress.

Right Coin Count (rCC)

For models equipped with the optional dual coin acceptor, by closing the program switch and pushing the “HI TEMP” keyboard (touch pad) selection button, the amount of coins inserted through the right coin slot of the coin acceptor can be viewed through the light emitting diode (L.E.D.) display. The computer memory will retain a running count of up to 9999 coins and can be cleared (CrCC) by following the program procedure on page 26.

Left Coin Count (LCC)

The number of coins inserted for a single coin acceptor dryer or in the case of a dual coin acceptor, the left coin slot can be viewed through the L.E.D. display by closing the program switch and pushing the “LO TEMP” keyboard (touch pad) selection button. The computer memory will retain a running count of up to 9999 coins and can be cleared (CLCC) by following the procedure on page 27.

PL01 - Temperature Conversion Status

This program controls whether the temperature-related programs will be operated in Fahrenheit or Celsius. Programs affected are:

1. Temperature display mode

2. Selection cycling temperatures

3. Cool down temperatures

Automatic Mode

When this parameter (“AUtO”) is selected, the dryer will run for a preset level of dryness (PL02) or until the programmed automatic maximum time (PL14) has expired.

At the end of the drying cycle, the dryer will go into the cool down cycle for the time period programmed (PL04, PL06, or PL08) or until the temperature has dropped to the programmed cool down temperature (PL04, PL06, or PL08).

NOTE: Due to humidity, atmospheric pressure, percentage of extraction, etc., the desired dryness level

may vary. It is suggested that the owner determine which level of dryness (90% to 100%) is best suited for his/her application by experimenting with a few test loads.

Timed Mode (tInE)

When this parameter is selected (“tInE”) and the Phase 3 microprocessor controller (computer) has been activated, the dryer will continue to run until the preset time, including the cool down period (PL04, PL06, or PL08), has elapsed, at which time the dryer will cycle off or go into the optional Antiwrinkle Program.

Antiwrinkle Program (Grd)

This feature can be used in conjunction with any of the three (3) operating modes (Coin Mode, Auto Mode, or the Free Dry Mode). In this program (“Grd”), when the drying and cooling cycles are completed, the dryer will shut off, the tone will sound, and the light emitting diode (L.E.D.) display will read “donE.” If the door is not opened, the Phase 3 microprocessor controller (computer) will wait until the “Guard Delay Time” (PL15) has expired, at which time the clothes will be tumbled (without heat) for the programmed “Guard On Time” (PL15). The Phase 3 microprocessor controller (computer) will repeat the process until the programmed “Active Guard Time” (PL16) has expired or until the dryer door is opened, at which time the L.E.D. display will read “FILL” and/or “Amount To Start” (“AtSt”), or “FILL” and/or “FrEE.”

Buzzer/Tone (bUZ)

With the Antiwrinkle Program active, the option is available to have the buzzer/tone (“bUZ”) sound for a period of 5-seconds at the end of each “Guard On Time” cycle.

Free Dry Mode (FrEE)

The Phase 3 microprocessor controller (computer) can be programmed to run without the insertion of coins. When the Phase 3 microprocessor controller (computer) is set in the “FrEE” dry mode, it reverts to the “AUtO” (Automatic) Mode.

Coin Mode (Coin)

In this program (“Coin”), coins are required to start the dryer, even if the Phase 3 microprocessor controller (computer) is set in the Automatic Mode.

Flash Display Status (FLS)

When the Phase 3 microprocessor controller (computer) is set in this program status (“FLS”), it allows the L.E.D. readout to display “FILL” (no cycle in progress), and the “Amount To Start” (PL12) or, in the case of free dry, “FrEE.” The programming allows the L.E.D. readout to flip-flop back and forth every 2-seconds from “FILL” to “Amount To Start,” or in the case of free dry, from “FILL” to “FrEE.”

Bad Coin Lockout Status (bCLO)

In this program status, the computer counts in milliseconds the amount of time required for a coin entry signal. If someone should tamper with the coin acceptor or attempt to insert a foreign object, the Phase 3 microprocessor controller (computer) will lock up, shut the dryer down, and the display will read “OFF.” This condition evident, even if coins are inserted, until the program is manually reset by closing and reopening the program switch (PS).

will be

Bad Coin Reset (bCrS)

When set in this program (“bCrS”), the Phase 3 microprocessor controller (computer) counts in milliseconds the amount of time required for a coin entry signal. If someone should tamper with the coin acceptor or attempt to insert a foreign object, the Phase 3 microprocessor controller (computer) will not accept the entry and will automatically reset itself immediately for the next entry.

Accumulative Time (AtIn)

Single Coin

In this program mode (“AtIn”), each coin inserted has a specific value in time, which is determined by the “Time Per Left Coin” (“tPLC”) program (PL11).

Example No. 1: If the dryer is equipped with a 25¢ coin acceptor and the desired time is 12 minutes, each

additional coin inserted would yield 12 minutes.

Settings: PL09 (LCdE) ............ 2 5

PL11 (tPLC) ............. 1 2

PL12 (AtSt) ............... 2 5

Example No. 2: If the dryer is equipped with a 25¢ coin acceptor and the “Amount To Start” (“AtSt”) is 50¢

for 30 minutes, the insertion of each additional coin would yield 15 minutes. In this application the “Time Per Left Coin” (“tPLC”) is determined by dividing the “Total Vend Time” (30) by the “Amount To Start” (“AtSt”) (i.e. 50¢) and then, multiplying by the Left Coin Denomination (“LCdE”).

Formula: (Total Vend Time/AtSt)(LCdE) = tPLC

(30/50)(25) = 15 minutes

Settings: PL09 (LCdE) ............ 25

PL11 (tPLC) ............. 1 5

PL12 (AtSt) ............... 5 0

Dual Coin

In the time accumulation mode, when using a dual coin acceptor, once the “Amount To Start” (“AtSt”) has been inserted, the addition of a coin(s) yields more time. The amount of time accumulated for each additional coin inserted is determined by the “Time Per Left Coin” (“tPLC”) program (PL11).

The “Time Per Left Coin” (“tPLC”) is determined by taking the “Total Vend Time” divided by the “Amount To Start” (“AtSt”) (PL12) and then, multiplying by the “Left Coin Denomination” (“LCdE”).

Formula: (Total Vend Time/AtSt)(LCdE) = tPLC

Example No. 1: Using a 10¢/25¢ dual coin acceptor with the desired “Amount To Start” (“AtSt”) being 25¢

for 15 minutes, each additional 10¢ would yield 6 minutes:

Formula: (15/25)(10) = 6 minutes (tPLC)

Settings: PL09 (LCdE) ............ 10

PL10 (rCdE) ............. 2 5

PL11 (tPLC) ............... 6

PL12 (AtSt) ............... 2 5

Example No. 2: If the dryer is equipped with a 10¢/25¢ dual coin acceptor and the “Amount To Start” (“AtSt”)

is 35¢ for 14 minutes, each additional 10¢ inserted would yield 4 minutes, and each additional 25¢ would yield 10 minutes.

Formula: (14/35)(10) = 4 minutes (tPLC)

Settings: PL09 (LCdE) ............ 1 0

PL10 (rCdE) ............. 2 5

PL11 (tPLC) ............... 4

PL12 (AtSt) ............... 3 5

Example No. 3: If the dryer is equipped with a 10¢/25¢ dual coin acceptor and the desired “Amount To Start”

(“AtSt”) is 55¢ for 33 minutes, each additional 10¢ inserted would yield 6 minutes, and each additional 25¢ would yield 15 minutes.

Formula: (33/55)(10) = 6 minutes (tPLC)

Settings: PL09 (LCdE) ............ 1 0

PL10 (rCdE) ............. 2 5

PL11 (tPLC) ............... 6

PL12 (AtSt) ............... 5 5

NOTE: If the Total Vend Time cannot be divided evenly by the “Amount To Start” (“AtSt”), the “Time

Per Left Coin” (“tPLC”) must be rounded off.

Formula: (35/55)(10) = 6.36 - Round off to 6 minutes.
