D. FRESH AIR SUPPLY REQUIREMENTS When the dryer is operating, it draws in room air, heats it, passes 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 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.
E. 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. Minimum diameter of ductwork must be at least 8-inches (20.32 cm).
IMPORTANT: Exhaust back pressure measured by a manometer in the exhaust duct must be no less than 0 and must not exceed 0.3 inches (0.74 mb) of water column (W.C.). NOTE: When the exhaust ductwork passes through a wall, ceiling, or roof made of combustible materials, the opening must be 2-inches (5.08 cm) larger than the duct (all the way around). The duct must be centered within this opening. IMPORTANT: It is recommended that exhaust or booster fans not be used in the exhaust ductwork system. a.
IMPORTANT: For extended ductwork runs, the cross section area of the ductwork can only be increased to an extent. When the ductwork approaches the maximum limits noted in this manual, a professional heating, venting, and air conditioning (HVAC) firm should be consulted for proper venting information. ALL ductwork should be smooth inside with no projections from sheet metal screws or other obstructions, which will collect lint.
3. Multiple (Common) Dryer Venting IMPORTANT: For extended ductwork runs, the cross section area of the ductwork can only be increased to an extent. When the ductwork approaches the maximum limits noted in this manual, a professional heating, venting, and air conditioning (HVAC) firm should be consulted for proper venting information.

H. 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. Care must be exercised when leveling steam dryers into final position. After leveling the dryer, check the downward pitch of the heat exchanger from front to rear with a level. Likewise, check the downward pitch of the return condensate manifold toward its outlet part.
IMPORTANT: Steam coil failure due to water hammer by wet steam will VOID THE WARRANTY. a. The pressure of the condensate in the steam supply will cause water hammer and subsequent heat exchanger (steam coil) failure. The steam supply connection into the main supply line must be made with 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.
4. Steam Damper Air System Connections Steam models are manufactured with a pneumatic (piston) damper system, which requires an external supply of compressed air. The air connection is made to the steam damper solenoid valve, which is located at the rear inner top area of the dryer just in front of the electric service relay box. a. Air Requirements There is no air requirement for dryers with the Electromechanical Steam Damper Option. COMPRESSED AIR SUPPLY AIR PRESSURE Normal 80 PSI 5.
c. Air Regulation No air regulator or filtration is provided with the dryer. External regulation/filtration of 80 PSI (5.51 bar) must be provided. It is suggested that a regulator/filter gauge arrangement be added to the compressed air line just before the dryer connection. This is necessary to insure that correct and clean air pressure is achieved. 5.
6. Steam Damper Air Piston (Flow Control) Operation Adjustment Damper operation was tested and adjusted prior to shipping at 80 PSI (5.51 bar). If damper air adjustment is necessary, locate the flow control valve and make the necessary adjustments as noted below.
I. PREPARATION FOR OPERATION/START-UP The following items should be checked before attempting to operate the dryer: 1. Read ALL “CAUTION,” “WARNING,” and “DIRECTION” labels attached to the dryer. 2.

SECTION VIII REVERSING TIMER SPIN/DWELL ADJUSTMENTS Dual timer models with “reversing option” have an electric reversing timer in the electric service box, which is located in the upper rear area of the dryer. Both the dwell (stop) time and basket (tumbler) spin time are adjustable by mode selection switches located on the electronic timer (as noted in the illustration below).
SECTION IX PROCEDURE FOR FUNCTIONAL CHECK OF REPLACEMENT COMPONENTS 1. Microprocessor Controller (Computer) Board a. Upon completing installation of the replacement microprocessor controller (computer) board, reestablish power to the dryer. b. Start the drying cycle by pressing any of the preset cycles in letters A-F. c. Verify that the applicable indicator lights on the back side of the microprocessor controller (computer) board are lit. (Refer to the illustration below.
2. For Models With Johnson Controls Direct Spark Ignition (DSI) Module (G760) 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.
SECTION X 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 basket (tumbler). A series of sensors positioned throughout the basket (tumbler) and interfaced with the microprocessor will trigger the S.A.F.E. system water jet(s) to quickly extinguish the flames.
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 1/2” M.P.T. bushing of the electric water solenoid valve located at the rear upper left area of the dryer (see photo). The water solenoid valve has a 3/8” 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. IMPORTANT: Flexible supply line/coupling must be used.
OPTIONAL MANUAL BYPASS Provisions are made in the dryer sensor activated fire extinguishing (S.A.F.E.) 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.
Sensor Activated Fire Extinguishing (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 basket (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 will be the trip point and the S.A.F.E. system routine will activate.
