Reach into the feed through hole in the base of the basket (tumbler) section, there will be two (2) cables there. Pull both cables through the hole into the basket (tumbler) section.
D. EXTERNAL SUPPLY CONNECTIONS 1. Compressed Air Supply A minimum requirement of 20 cfh (0.57 cmh) 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.
2. Gas Piping The gas connection to the dryer is made into the 2-1/2” F.P.T. shutoff 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 mb) and 13 inches (32.34 mb) water column (W.C.) for natural gas or 10.5 inches (26.12 mb) water column (W.C.) for liquid propane (L.P.) gas.
3. Steam Supply and Condensate Return Connections The steam supply line into the dryer is made into the 2-1/2” F.P.T. pipe fitting located on top of the heat module console. The maximum operating steam supply pressure is 150 psig (1,034 kPa). The presence of condensate in the steam supply line will cause water hammer and subsequent steam coil (battery) failure. The steam supply connection out of the main supply line must be made with a minimum 10-inch (25.4 cm) riser.
E. FRESH AIR SUPPLY REQUIREMENTS When the dryer is operating, it draws in room air, heats this air through the basket (tumbler), and exhausts it out of the building. Therefore, the room air must be continually replenished from the outdoors. If make-up 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.
F. EXHAUST REQUIREMENTS 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 basket (tumbler) hi-limit thermostats. The dryer must be installed with a proper exhaust duct connection to the outside.

26
a. Outside Ductwork Protection 1) To protect the outside end of the horizontal ductwork from the weather, a 90º elbow bent downward should be installed where the exhaust exits the building. If the exhaust ductwork travels vertically up through the roof, it should be protected from the weather by using a 180º turn to point the opening downward. In either case, allow at least twice the diameter of the duct between the duct opening and nearest obstruction.
G. STEAM INFORMATION It is your responsibility to have ALL plumbing connections made by a qualified professional to assure that the steam plumbing installation is adequate and conforms with local and state regulations or codes. IMPORTANT: Failure to comply with the requirements stipulated in this manual can result in component failure, which will VOID THE WARRANTY.
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.
H. SHUTDOWN INSTRUCTIONS If the dryer is to be shutdown (taken out of service) for a period of time, the following must be performed: 1. Discontinue power to the dryer either at the external disconnect switch or the circuit breaker. 2. Discontinue the heat supply: a. GAS MODELS...discontinue the gas supply. 1) SHUT OFF external gas supply shutoff valve. 2) SHUT OFF internal gas supply shutoff valve located in the gas valve burner area. b. STEAM MODELS...discontinue the steam supply.
J. PREOPERATIONAL TESTS 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. 1. Turn on electric power to the dryer. 2. Make sure the loading doors are closed and the lint drawer is closed. 3. Press in “green” power button and it will illuminate. 4.
NOTE: Mechanical functions of the dryer are 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. 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” key is pressed, the dryer will go into a Cool Down Cycle.
IMPORTANT: There is no regulator provided in a liquid propane (L.P.) dryer. The water column (W.C.) pressure must be regulated at the source (L.P. tank) or an external regulator must be added to each dryer. b. Steam Models 1) Check to insure that the steam damper is functioning properly. 2) Make a complete operational check of ALL safety related circuits (i.e., lint drawer switch and sail switches on gas models).
5. GAS MODELS - Be sure that ALL gas shutoff valves are in the open position. 6. Be sure ALL side and base panels are on the dryer. 7. Check ALL service doors to assure that they are closed and secure. 8. Be sure lint drawer is securely in place. NOTE: LINT DRAWER MUST BE ALL THE WAY IN PLACE TO ACTIVATE SAFETY SWITCH OTHERWISE THE DRYER WILL NOT START. 9. Rotate the basket (tumbler/drum) by hand to be sure it moves freely. 10. Check bolts, nuts, screws, terminals, and fittings for security. 11.

SECTION IV COMPONENT SYSTEM DESCRIPTIONS A. BASKET (TUMBLER) DRIVE SYSTEM The basket (tumbler) is supported and driven by four (4) 11-inch (27.94 cm) diameter drive wheels. Two (2) of these wheels are attached to a 2-inch (5.08 cm) diameter idler shaft, while the other two (2) are attached to a 2-inch (5.08 cm) 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.
B. MAIN AIR BLOWER AND HEAT RECLAIMER SYSTEM The fan which moves the exhaust air through the dryer is a 22-inch (55.88 cm) diameter, squirrel cage wheel that is driven at 1,100 RPM by a 25 HP (18.6 kw) motor. This fan moves a maximum of 13,000 cfm (368 cmm) air through the dryer.
The dryer is equipped with a pneumatically operated heat reclaimer damper, which when opened, will recirculate approximately fifteen percent (15%) of the dryer’s exhaust air. The heat reclaimer damper is closed until ignition of flame has been established. Then, the damper piston is actuated, opening the dampers recirculating fifteen percent (15%) of the exhaust air back over the gas burner and into the tumbler (basket). The damper remains open for the rest of the drying cycle.
C. GAS BURNER AND IGNITION SYSTEM The dryer gas burner system operates on an on/off gas rate sequence to accurately control the basket’s (tumbler’s) drying temperature. Maximum firing rate is 2,800,000 BTU/hr (705,588 kcal/hr). Upon a call from heat, the dryer computer sends a 120 volt signal to the burner controller module (BCM), which initiates and controls the ignition sequences.
1. Major Burner Components a. Burner Controller Module (BCM) The BCM provides effective burner flame safeguard control through adjustable purge and trial-forignition timing. The BCM insures that ALL dryer safety switch circuits are closed, delays ignition to allow the combustion chamber to vent, and insures that a healthy pilot flame is established before opening the main gas valves. Five (5) light emitting diodes (L.E.D.s) on the cover of the BCM allow for easy troubleshooting.
2) Light emitting diode (L.E.D.) and Neon Displays of the Burner Controller Module (BCM) a) Operating Interlock - L.E.D. is lit when: ALL safety interlock switches are closed applying a 120 VAC signal to terminal #7 of the BCM. b) Operating Interlock - L.E.D. is not lit when: One or more safety interlock switches are open. If any safety interlocks switch is open the burner ignition sequence will not be attempted. c) Air Failure - L.E.D.
h) Burner Fan Air Switch Status Indicator - Neon is not lit: • • • • Air switch is not closed after start-up of burner fan. Door interlocks are open. Combustion burner screen is clogged. A door on the dryer is open. i) Pilot Test/Reset Button When this button is pushed in, the burner controller module (BCM) will halt the ignition sequence, once the pilot flame is established. This allows the pilot flame to be adjusted.
a) Burner Fan Air Switch The differential in air pressure is measured by the burner fan air switch, which is located next to the burner fan motor. If the combustion air is inadequate, this switch will prevent ignition. The setting of this switch is adjustable, and it should be set at 12 to 15 millimeters (0.4-0.6 inches [0.995-1.49 mb] of water column [W.C.]). b) Burner Fan and Motor The combustion air is produced by a 6-1/4” (15.88 cm) squirrel cage fan, which is attached to a 1-1/2 HP (1.
(2) The pilot line contains a back-loaded pressure regulator with an impulse line connected to the gas burner inlet. The regulator will maintain a constant pilot supply pressure in the burner due to an increase in temperature. DO NOT adjust this regulator. 6) Main Gas Supply Line The main gas supply line consists of a pressure regulator, two (2) motorized shutoff valves, Hi/Lo gas pressure switch, main gas valve proof of closure switch, and manual shutoff valve. The gas pressure at the burner should be 2.
If ALL safety switches are closed, the burner controller module (BCM) will start the burner fan motor (BCM terminal #8). The BCM waits 10-seconds to allow the blower motor to get up to speed, and then checks that the burner fan combustion air switch (BCM terminal #6) circuit is closed. If this circuit is open during the drying cycle, the “Air Failure” light emitting diode (L.E.D.) will light. The gas valve will close, and a “HEATER FAULT” message will be displayed.
Once the flame probe signal is detected by the burner controller module (BCM), it waits 5-seconds to allow the pilot to stabilize and then opens the main motorized gas valves (BCM terminal #5) in sequence. The lower valve opens first. Upon full opening, its’ internal switch closes, enabling the second motorized valve to open and full flame to be achieved. If flame failure occurs within a 35-second period, the BCM will recycle the ignition sequence once.
2. Electrical Service The electrical power is connected to the dryer at the high voltage section of the control cabinet. On the dryer, this section is located at the bottom left of the main electrical enclosure. 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.
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 “door.” 2.
SECTION V PRE START-UP A. PREPARATION FOR OPERATION 1. The supply voltage must match the dryer voltage as stated on the aluminum dryer data label which is located in the right hand side of the main electrical enclosure. 2. Open ALL steam supply lines and condensate return line shutoff valves. 3. A compressed air supply of 80 PSI (5.51 bar) must be connected into the dryer’s fitting located at the rear corner of the lower heat console section. 4. The dryer exhaust duct must be vented to the outdoors. 5.
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.
MONTHLY Empty the compressed air filter bowl. Regrease the two (2) 1-3/8” bearings that support the impellor/fan shaft. Use Shell Alvania #2 grease or its equivalent. Impellor/fan shaft bearings must be lubricated. EVERY 3 MONTHS Apply a Hi-temperature grease to the four (4) 1-1/2” diameter basket (tumbler) drive shaft pillow block bearings. (Use Shell Alvania #2 grease or its equivalent). Retighten setscrews in the collars of the four (4) 1-1/2” diameter basket (tumbler) drive shaft bearings.
B. ADJUSTMENTS 7 DAYS AFTER INSTALLATION AND EVERY 6 MONTHS THEREAFTER Inspect bolts, nuts, screws (bearing setscrews), grounding connections, and nonpermanent gas connections (unions, shutoff valves, and orifices). Motor and drive belts should be examined. Cracked or seriously frayed belts should be replaced. Tighten loose V-belts when necessary. Complete operational check of controls and valves.
SECTION VII DATA LABEL LOCATION/INFORMATION A.

SECTION IX SUPPRESSION SYSTEM The exclusive Suppression System will extinguish fires that may start in the drying basket (tumbler). A series of sensors positioned throughout the basket (tumbler) and interfaced with the microprocessor will trigger the suppression system water jets to quickly extinguish the flames. The water jets remain on for 2 minutes and will automatically activate again if a fire condition remains or reignites.
BEFORE YOU START! CHECK LOCAL CODES AND PERMITS Call your local water company or the proper municipal authority for information regarding local codes. IMPORTANT: It is your responsibility to have ALL plumbing connections made by a qualified professional to assure that the plumbing installation is adequate and conforms to local, state, and federal regulations or codes.
2. Water Connections: The water connection is made to the 1” F.P.T. bushing of the electric water solenoid valve located at the front lower left area of the dryer. The water solenoid valve has a 1/2” M.P.T. connection and a 1/2” bushing is supplied to provide the minimum 1/2-inch supply (feed) line. Flexible supply line/coupling must be used in effort to avoid damage to electric water solenoid valve. WARNING: Water must be supplied to suppression system or dryer will not operate.
OPTIONAL MANUAL BYPASS Provisions are made in the dryer suppression system for the installation of an optional manual bypass. Depending on the model dryer, the connections for the manual bypass are made at the “T” or “four way” fitting located in the outlet supply side of the water solenoid valve. The use and connections of this manual bypass are at the option or discretion of the owner. The water connection for the manual bypass is made to the “T” or “four way” fitting which has a 1/2” F.P.T.
Suppression 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 suppression system probe located in the top of the basket (tumbler) chamber and records the minimum temperature. If the minimum recorded suppression system probe temperature is no less than 120° F (48° C) and the control detects a 50° rise in temperature, this will be the trip point and the suppression system routine will activate.
