KEEP SHIELDS, GUARDS, AND COVERS IN PLACE. These safety devices are provided to protect everyone from injury. WARNING: Do not stop dryer before end of cycle time unless all items are quickly removed and spread out to dissipate heat. It is ABSOLUTELY ESSENTIAL that the dryer be grounded to a known earth (zero) ground in accordance with local codes or, in the absence of local codes, with the latest editions of the National Electric Code, ANSI//NFPA 70 or Standard CSA C22.1 Canadian Electrical Code Part 1. This is not only for personal safety, but is necessary for proper operation of the controller. Failure to do so will void the warranty of the controller. A DRYER SHOULD BE CONNECTED TO POWER FOR THREE (3) MINUTES before it is operated or before a program change is made. Operation or program changes, which occur during this "power up" period, are subject to loss in case of power interruption. After the initial three minutes, all programmed data is protected from power interruptions of any length and the customer's individual cycle is protected up to 3 seconds. This is done without batteries. LEAVE THE ELECTRICAL POWER TO THE DRYER ON AT ALL TIMES except when necessary for service or other similar activities. The hour meter function adds only full hours to its reading. If the power is shut off every night, any fraction of an hour of time that is on the machine at that time will be lost. Turning the power off every night could also have some effect on the long-term life of the memory after a number of years. Turning power off occasionally won t affect the unit. THIS DRYER IS EQUIPPED WITH AN OVER-TEMPERATURE THERMOSTAT located to the right of the motor on the rear of the cabinet. If the dryer ceases to operate, refer to your Service Procedure and Parts Data book for instructions. CHECK THIS THERMOSTAT WHEN INSTALLING DRYER to assure it is not tripped. Impacts such as rough handling in shipment, may trip the thermostat. It may be reset by inserting a wooden pencil or dowel through the bushing in the cover. DO NOT SPRAY AEROSOLS IN THE VICINITY OF THIS APPLIANCE while in operation. THIS APPLIANCE SHALL NOT BE USED TO DRY OFF SOLVENTS OR DRY-CLEANING FLUIDS REV F page 2

15 INSTALLATION AND OPERATING INSTRUCTIONS UNCRATING AND PLACING DRYER Tools Required: 3/4" (19 mm) hex socket & ratchet driver, wood block 4" (100 mm) or 5" (125 mm) thick, a knife and a groove joint pliers, which will open to 1 3/8" (35 mm). 1. Remove and discard packaging. 2. The crate base is attached to the dryer by (4) cap screws driven upward from below the crate base. Remove crate base from dryer, by tipping dryer sidewise and place block under crate base rail in center of dryer. Using a ratchet and 3/4" hex socket, remove and discard (2) crating bolts from side, which is raised. Remove block from under crate base. Repeat for other side. Save the bolts for use if the dryer is ever moved again. 3. With a walking motion move dryer completely off crate base. Save the crate base for use if the dryer is ever moved again. 4. Slide unit into position where it will be installed. Adjust leveling legs, using the groove joint pliers, to level and align dryer with adjacent units. Note: If the dryer is ever moved again, the dryer should be re-mounted on its crate base and its crating bolts reinserted and tightened, in the reverse order as above. DRYER INSTALLATION 1. CODE CONFORMITY: All commercial dryer installations must conform with local codes, or in the absence of local codes, with the latest edition of the National Fuel Gas Code ANSI Z Canadian installations must comply with the current Standard CAN/CGA-B149 (.1 or.2) Installation Code for Gas Burning Appliances or Equipment, and local codes if applicable. Australian installations must meet installation requirements and pipe sizing requirements of AS/NZA The appliance, when installed, must be electrically grounded in accordance with the latest edition of the National Electric Code, ANSI/NFPA70, or, when installed in Canada, with Standard CSA C22.1 Canadian Electrical Code Part 1. 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. 2. INSTALLATION CLEARANCES: This unit may be installed at the following alcove clearances: I. Left Side 0" II. Right Side 0" III. Back 18" (457 mm) (Certified for 6" (150 mm) clearance; however, 18" (457 mm) clearance is necessary behind the motors to allow servicing and maintenance.) IV. Front 48" (1220 mm) (to allow use of dryer) V. Top Refer to figure labeled Vertical Clearance Dimensions. AB. Certification allows 0" clearance at the top 4" (100 mm) back from the front. However, a 1/4" (6 mm) clearance should be allowed so that the upper service door can be opened. C. A 10" (250 mm) clearance is required from top at all other points. VI. Floor This unit may be installed upon a combustible floor. Do not obstruct the flow of combustion and ventilation air. Maintain minimum of 1" (25 mm) clearance between duct and combustible material. Refer to the label attached to the Belt Guard on the rear of the dryer for other installation information and start-up instructions REV F page 15

16 VERTICAL CLEARANCE DIMENSIONS 3. MAKE-UP AIR: Adequate make-up air must be supplied to replace air exhausted by dryers on all types of installations. Refer to specifications for the minimum amount of make-up air opening to outside for each dryer. This is a net requirement of effective area. Screens, grills or louvers, which will restrict the flow of air, must be considered. Consult the supplier to determine the free area equivalent for the grill being used. The source of make-up air should be located sufficiently away from the dryers to allow an even airflow to the air intakes of all dryers. Multiple openings should be provided. The sources of all make-up air and room ventilation air movement to all dryers must be located away from any dry cleaners. This is necessary so that solvent vapors will not be drawn into the dryer inlet ducts. Dry cleaner solvent vapors will decompose in contact with open flame such as the gas flame present in clothes dryers. The decomposition products are highly corrosive and will cause damage to the dryer(s) ducts and clothes loads. The operation of this appliance may affect the operation of other types of gas appliances, which take their air for safe combustion from the same room. Adequate ventilation must be provided to avoid back flow of gasses from other appliances in the same room. All other gas appliances should be tested with the Dexter dryer in operation and all the windows and doors closed. If in doubt consult the appliance manufacturer(s). 4. ELECTRICAL REQUIREMENTS. The electrical power requirements necessary to operate the unit satisfactorily are listed on the serial plate located on the back panel of each dryer and in the specifications section of this manual. The electrical connection should be made to the terminal board, on the rear of the unit. It is absolutely necessary that the dryer be grounded to a known ground. Individual circuit breakers for each dryer are required. The installer must provide a disconnect switch which will interrupt both lines. It may be a local or national requirement to provide an electrical interruption switch visible and accessible from the room in which the dryer is installed. The wiring diagram is located on the belt guard on back of the dryer. 5. GAS REQUIREMENTS. The complete gas requirements necessary to operate the dryer satisfactorily are listed on the serial plate located on the back panel of the dryer and in the specifications section of this manual. The inlet gas connection to the unit is 1/2-inch pipe thread for T-30 and T-50 and 3/4-inch for T-80. However, the size of the piping to supply the dryer should be determined by reference to the National Fuel Gas Code ANSI Z223.1A and consultation with the local gas supplier REV F page 16

17 An individual gas shutoff valve is recommended for each dryer and may be required by local code (not supplied). A joint compound resistant to the action of liquefied petroleum gases should be employed in making pipe connections. A 1/8-inch NPT plugged tapping, accessible for test gage connection, must be installed immediately upstream of the gas supply connection to the dryer. A drip tee is provided in the unit gas piping to catch dirt and other foreign articles. All pipe connections should be checked for leakage with soap solution. Never check with an open flame. For altitudes above 2,000 feet (610m), it is necessary to derate the BTU input. Contact your local distributor for instructions. L.P. gas conversion kits are available for this dryer. Contact your local distributor. CAUTION: The dryer must be disconnected from the gas supply piping system during any pressure testing of that system. Do not expose the dryer s gas control valve to testing pressure. 6. EXHAUST INSTALLATION. Exhausting of the dryer(s) should be planned and constructed so that no air restrictions occur. Any restriction due to pipe size or type of installation can cause slow drying time, excessive heat, and lint in the room. From an operational standpoint, incorrect or inadequate exhausting can cause a cycling of the high limit thermostat, which shuts off the main burners and results in inefficient drying. The exhaust duct connection near the top of the dryer will accept an 8 (200 mm) round duct. Individual exhausting of the dryers is recommended. All heat, moisture, and lint should be exhausted outside by attaching a pipe of the proper diameter to the dryer adapter collars and extending it out through an outside wall. This pipe must be very smooth on the inside, as rough surfaces tend to collect lint, which will eventually clog the duct and prevent the dryer from exhausting properly. All elbows must be smooth on the inside. All joints must be made so the exhaust end of one pipe is inside the next one downstream. The addition of an exhaust pipe tends to reduce the amount of air the blower can exhaust. This does not affect the dryer operation if held within practical limits. For the most efficient operation, it is recommended that no more than 14 ft. (4.25 m) of straight 8 in. diameter pipe with two right angle elbows be used for each cylinder. Maintain a minimum of 1 (25mm) clearance between duct and combustible material. If the exhaust pipe passes through a wall, a metal sleeve of slightly larger diameter should be set in the wall and the exhaust pipe passed through this sleeve. This practice is required by some local codes and is recommended in all cases to protect the wall. This type of installation should have a means provided to prevent rain and high winds from entering the exhaust when the dryer is not in use. A hood with a hinged damper can be used for this purpose. Another method would be to point the outlet end of the pipe downward to prevent entrance of wind and rain. In either case, the outlet should be kept clear, by at least 24 in. (610 mm) of any objects, which would cause air restriction. Never install a protective screen over the exhaust outlet. When exhausting a dryer straight up through a roof, the overall length of the duct has the same limits as exhausting through a wall. A rain cap must be placed on top of the exhaust and must be of such a type as to be free from clogging. The type using a cone shaped roof over the pipe is suitable for this application. Exhausting the dryer into a chimney or under a building is not permitted. In either case there is a danger of lint buildup, which can be highly combustible REV F page 17

18 NOTE: Exhaust air must not be discharged into a flue which is used for exhausting fumes from appliances. Do not discharge exhaust air into the exhaust duct used to exhaust fumes of other equipment. 7. DRYER IGNITION (SOLID STATE IGNITION): The solid-state ignition system lights the main burner gas by spark. The gas is ignited and burns only when the gas-relay (in the electronic controller) calls for heat. The procedure for first-time starting of a dryer is as follows. i. First review and comply with the "Warnings About Use and Operation" found on the inside front cover of this manual. Be sure electrical power is connected correctly. The dryer must be properly grounded. ii. Make sure all gas supply lines are purged of air. Close the main gas shut-off valve and wait for five minutes before turning it back on. iii. Turn on the main electrical power switch. The dryer may be started by following the "Operating Instructions" found later in this manual. iv. Natural gas and LPG fired dryers operate in the same manner. When the gas valve relay contacts are closed (indicating a demand for heat), the solid-state ignition control will automatically supply energy to the redundant gas valve. Sparking will continue until a flame is detected by the sensing probe, but not longer than ten seconds. If the gas fails to ignite in 10 seconds, the gas valve closes and the gas system pauses to allow gas to purge from the inside of the dryer. After the pause, the ignition control repeats the ignition trial cycle twice more. If the gas system fails to detect ignition after the three attempts, the system will "lock out". No further attempts will be performed automatically. To reset the ignition control electrical power to the ignition control must be interrupted. This can be done by opening the dryer door (stopping the dryer) for 15 seconds. Closing the door and pushing the "Start" button will repeat the ignition trial cycle. DRYER SHUTDOWN To render the dryer inoperative, turn off the main gas shut off valve and disconnect the electrical supply to the dryer. NOTE: It is recommended that the installer test the dryer for operation and instruct the user before leaving the installation. OPERATING INSTRUCTIONS STARTING THE DRYER REV F page 18

19 1. The display on the dryer control will show the required vend amount when in idle mode. Once the door is opened it will prompt the user to add money. Load clothes into the dryer. Close the door completely. 2. Deposit coins equal to or greater than the displayed vend price. The display on the control will prompt the user to choose a drying temperature. 3. Select the drying temperature by pressing the appropriate button for high, med (medium) or low. This will turn on the red indicator light showing the selected temperature. 4. Press the start button to start dryer. This will turn on the green indicator light. The drying time purchased is now displayed. The colon begins flashing to indicate that the timer is counting down. RUNNING THE DRYER -Opening the door will stop the dryer, but the timer will continue to count down. The dryer will restart, if time has not expired, upon closing the door and pressing the start button. -Selected temperature may be changed at any time (unless Temperature Pricing feature is activated). -Running time may be extended by depositing coins and pressing the start button. Unless time has expired, the controller will accept coins whether or not the original vend price is equaled. -If time has run out, the dryer must be restarted as if it was at the beginning of drying the load, which requires meeting or exceeding the vend price. -Clothes should be removed promptly after the cycle is completed to prevent excessive wrinkling. -Cool-down time (owner programmable) is always part of the cycle time to prevent damage from heat and is purchased by the customer. For example, if the cool-down time is 2 minutes, then the last 2 minutes of the cycle will have no heat. PROGRAMMING THE DRYER CONTROL The dryer control can be programmed to prompt the user for alternate vend prices, change dryer cycle times, temperatures and many other options. This can be accomplished in two ways: 1. Manual programming utilizing the Start, High, Medium and Low buttons. 2. USB download of a pre-programmed User File. For instructions on using the USB download feature, please contact your local Dexter distributor. MANUAL PROGRAMMING: The dryer must be in idle mode for the manual programming menus to be accessed. Idle mode is when the dryer is not actively running a drying cycle and the vend price is displayed on the screen. To enter the manual programming mode, the upper service door on the dryer must be unlocked and lifted to reveal the back side of the control. The programming button is found in the location shown below. The programming button is then pressed for 1 second. The control should display DRYER PROGRAMMING. See the figure below for the location of the programming button on the dryer control. Please note, this is the control as viewed from the underside of the lifted service door REV F page 19

20 When manual programming mode is entered, the Start, High, Medium and Low buttons perform alternate functions. Button Name Start High Medium Low Alternate Function in Programming Mode Becomes the action to accept the displayed option or the Enter key Becomes the action to move UP through displayed options (Press & hold for accelerated scrolling) Becomes the action to move DOWN through displayed options (Press & hold for accelerated scrolling) Becomes the action to move back a step (1 press) or EXIT from programming mode (press for 3 seconds) REV F page 20

21 These alternate functions allow the user to move through a menu of options to choose various programmable settings. The figure below shows the top level menu. Choosing an option from the top level menu will then display the next level of options (the sub menu). Quick Test Option: When the Quick Test Option is chosen, the dryer will begin a shortened dry cycle without the displayed vend price being met. The purpose of this shortened cycle is to test all major components for proper operation. Error Codes should all function normally during this test. The display will show customer prompts in a similar way to a normal dry cycle. Continuous Test Option: Similar to the Quick Test, when the Continuous Test Option is chosen, the dryer will begin a dry cycle without the displayed vend price being met. However, in this case, it will be a continuously-running cycle. It will not time out after any designated amount of time. CAUTION: This option is meant for factory use only. Do not operate the dryer with this cycle active without factory authorization REV F page 21

22 Error Code Historical Log: The last five occurring error codes will be stored in the control with a time and date stamp. The purpose of this option is only to observe the history of these code occurrences (no changes can be made). The time is based off the Real Time Clock, but potentially shifted by the user s manual programming changes (Shift Hours option) and/or network time override. As additional error codes occur, the oldest of the five logged codes is cleared from memory. Prices Option: This option allows the user to set values for coin acceptor inputs, vend price & time and extend dry price & time. It also allows the user to return the values to factory defaults. After changing prices using the Up or Down buttons, the Enter button must be pressed again for the control to store the changes that have been made. Note that, in general, time values are set in 1 minute increments. This can be changed to 30 second increments, by changing the Display Time to MIN+SEC (refer to the Settings section ). 1. RIGHT COIN and LEFT COIN are the two possible inputs from coin acceptors. 2. PRICE SET VEND is the actual Base Vend Price (or Vend Price A) that is shown on the control display. The value can be increased or reduced even down to 0. In this case, the displays will prompt FREE and the cycle will start as soon is the Start button is pressed (without any vend price being met). 3. TIME SET VEND is the cycle time that the customer has available once they ve met the Base Vend Price. 4. FREE SET TIME is the cycle time that the customer has available if the Base Vend Price is set to FREE. 5. EXTEND DRY sets the price and time for additional drying time that becomes available after the customer has already met the Base Vend Price. To reset either the coin acceptor inputs or the vend price to factory default, press Enter when the DEFAULT prompt is shown. Press Enter again when the RESET prompt is shown to confirm the action. Example- A store owner has programmed the control for the following values: Base Vend Price $1.00 Base Vend Time 30 minutes Extend Dry Price $.25 Extend Dry Time 8 minutes In this case, the customer adds 4 quarters to satisfy the $1.00 Vend Price. The display shows 30 minutes of drying time. At this point, if an additional quarter is added, the customer display shows an additional 8 minutes of drying time (38 minutes total) as per the Extend Dry Price & Time. The customer starts the drying cycle and at 25 minutes into the cycle (13 minutes displayed), they add an additional quarter. The controller adds 8 minutes to the displayed time again (21 minutes total) as per the Extend Dry Price & Time. AFTER CYCLE allows the user to choose whether a customer is allowed to add EXTEND DRY time for up to 30 seconds after the dryer door is opened after a completed cycle REV F page 22

23 The figure below shows the sub menu options for Prices: REV F page 23

24 Cycles Option: This option allows the user to set temperature and cooldown information for the drying cycle. It also allows the user to return the values to factory defaults. 1. TEMP SETTINGS allows the user to make adjustments, within a designated range, to the cycling temperature for each of the Low, Medium and High customer choices. 2. In addition, on the Low setting, the user can reduce the cycling temperature below 110 degrees F. In this case, when the customer chooses the Low setting, the dryer will not turn on the gas valve. When checked, the displayed temperature will read NO HEAT. 3. COOLDOWN allows the user to change the designated time at the end of a cycle where the gas valve relay is turned off. On High and Medium temperature settings, the designated time cannot be reduced to less than 2 minutes. 4. DEFAULT TEMP allows the user to choose which general temperature setting, High, Medium or Low, the control will default to at the beginning of each cycle if the customer does not make a choice. 5. ANTI WRINKLE is a feature that periodically rotates the dryers after a cycle is complete. If the door was closed at the end of the cycle, and is left closed for 5 minutes, the enunciator will sound and the display begins scrolling ANTI WRINKLE. 5 seconds later, the dryer motor will turn on for 60 seconds and then turn off. The gas valves will not be turned on. The ANTI WRINKLE message will continue throughout the time that the motor is turned on. The user can choose to enable or disable this feature.

26 Temperature Pricing Option: This option allows the user to require additional vend amounts be added based on the drying temperature chosen by the customer. This pricing adder is effective only for the Base Vend Price (it does not affect the Extend Dry Price). It allows a pricing adder separate for Medium and Hot temperature settings. Example- A store owner has programmed the control for the following: Vend Price $1.00 Vend Time 30 minutes Extend Dry Price $.25 Extend Dry Time 8 minutes Medium Adder $.25 Hot Adder $.50 In this case, the Vend Price is displayed as: $1.00 if Low Temperature is chosen $1.25 if Medium Temperature is chosen $1.50 if Hot Temperature is chosen When Temperature Pricing Adders are in place (user has chosen a higher value than $0.00), if the customer attempts to change their temperature selection from a lower temperature to a higher one during a drying cycle, there will be no change in the temperature selection. The higher temperature buttons are disabled until the drying cycle is complete and a new Vend Price is required. The figure below shows the sub menu options for Temperature Pricing: Settings Options: The Settings options allow for the user to make various programming changes to change how the control operation affects the customer. See below for detailed information on each next level option. 1. Decimal Point : If the user programs the Decimal Point to OFF, control display will not show a decimal point on any vend price values. The factory default is ON. 2. Display Time : If the user programs this value to MIN, then minutes only will be shown for the cycle time. If it is programmed to MIN+SEC, then minutes and seconds will be shown. This also allows other programming changes, involving time, to be made in either minute increments or minutes & seconds increments, as desired. 3. Temp Scale : If the user programs this value to F, then the temperatures will be displayed in Fahrenheit units. If it is programmed to C, then the temperature will be in Celsius units. 4. Sounds : If the user programs the Sounds to OFF, the control will not sound the enunciator at the end of a dry cycle. The factory default is ON. 5. Password : If the user programs the password to any value other then 0000, the control will prompt the user to enter a password (the programmed value) before manual programming can be accessed. The factory default is 0000 (no password). a. Note that if the user forgets the Password, it can be reset to factory default (no password), by performing a hard reset on the control. Please refer to the appropriate section of this manual to understand how to perform a hard reset. b. The individual digits of the Password can be set by using the Up or Down buttons to change the number that is flashing. Once the desired number is chosen for a single digit, press the Enter button to move to the next one. Once all four desired digits are chosen, the Enter button must be held down for 3 seconds to confirm that the complete password should be set REV F page 26

27 6. Language : The control uses English for the default language of the customer prompts. Alternatively, the user can choose Spanish, French, Malay, or Italian for the customer display prompts. However, all other prompts, such as Manual Programming, USB Programming and any Error Codes will still display in English. 7. Shift Hours : This feature allows the user to shift the time used by the control from the time kept internally by the control. The control uses a Real Time Clock (RTC) to internally track the time and date. The RTC continues operation even if the control loses external power. The RTC is set for Central Standard Time and no daylight savings. Because the machine may be located in another time zone, the user can choose to create an alternate time & date that tracks in parallel to the RTC. When this alternate time is chosen, or shifted from the RTC, the alternate time will be used to, for example, track error code occurrences and set time-of-day pricing changes. a. The hours in SHIFT HOURS can be set by using the Up or Down buttons to change the number that is flashing. Once the desired hour shift is chosen, press the Enter button to move to the minutes. Once the hours and minute shift are both chosen, the Enter button must be held down for 3 seconds to confirm that the complete shifted time is set. 8. Time : The control uses a Real Time Clock (RTC) to internally track the time and date. The RTC continues operation even if the control loses external power. The RTC is set for Central Standard Time and no daylight savings. However, if a problem occurs and the RTC time is not accurate, it can be reset to the current time using this option. a. The hours in TIME can be set by using the Up or Down buttons to change the number that is flashing. Once the desired hour is chosen, press the Enter button to move to the minutes. Once the hours and minute are both chosen, the Enter button must be held down for 3 seconds to confirm that RTC is meant to be reset to the complete entry. 9. Date : Similar to Time, if a problem occurs and the RTC date is not accurate, it can be reset to the current date using this option. a. The day of the month in DATE can be set by using the Up or Down buttons to change the number that is flashing. Once the desired day of the month is chosen, press the Enter button to move to the month of the year. Once the desired month of the year is chosen, press the Enter button to move to the year. Once the day, month and year are all chosen, the Enter button must be held down for 3 seconds to confirm that RTC is meant to be reset to the complete entry. 10. Out of Service The control can be put into an Out-of-Service mode via manual programming. When the mode is ON, the control will scroll OUT OF SERVICE on the display. The machine will not react to any vend input and will not operate when in this mode. The factory default is OFF. To reset all values in the Settings options to factory default, press Enter when the DEFAULT prompt is shown. Press Enter again when the RESET prompt is shown to confirm the action REV F page 27

28 The figure below shows the sub menu options for Settings: REV F page 28

29 Usage Menu: The Usage menu allows for the user to track data about machine usage. See below for detailed information on each sub menu option. 1. Coin Audit : The coin audit field shows the accumulation of coin pulses that were sent to the control over each of the left and right coin inputs. Note that this is a count of coin pulses, not an accumulated report of vend value. a. The user can also return the coin audit amounts to the factory default setting (zero). To reset all coin audit values, press Enter when the DEFAULT prompt is shown. Press Enter again when the RESET prompt is shown to confirm the action. 2. Motor Hours : The motor hours field shows the accumulated hours of operation for the dryer motor. In many cases, it will match the cycle hours of the machine. However, separate fields are provided in the event that a motor is replaced on a machine. The user can set the motor hours to a designated number. For example, if it is necessary to replace the control on a machine, the new control could be programmed to show the motor hours that were recorded by the previously installed control. The individual digits of the hours count can be set by using the Up or Down buttons to change the number that is flashing. Once the desired digit of the hours is chosen, press the Enter button to move to the next digit. Once the complete hours are chosen, the Enter button must be held down for 3 seconds to confirm the action. a. The user can also return the motor hours to the factory default setting (zero). To reset the motor hours, press Enter when the DEFAULT prompt is shown. Press Enter again when the RESET prompt is shown to confirm the action. 3. Cycle Hours : The cycle hours field shows the accumulated hours of operation for the dryer. In many cases, it will match the motor hours of the machine. However, separate fields are provided in the event that a motor is replaced on a machine. See the Motor Hours description for more information. The figure below shows the sub menu options for Usage: REV F page 29
