  • Page 20: Washer Installation

    Washer Installation All washers must be installed in accordance with all local, state and national building, electrical, and plumbing codes in effect in the area. Foundation Requirements The washer must be securely bolted to a substantial concrete floor, or mounted upon a suitable base which is securely bolted and machine grouted to a substantial concrete floor.
  • Page 21 To Make Electrical Connections Disconnect all power to the washer. Remove screw and lift the cover located in the upper left corner of the machine (as viewed from the back). • If power is 208-240-3PH-60Hz, connect L1, L2, L3, and ground. If there is a high leg it must be connected to L3.

  • Page 22: Dryer Installation

    Dryer Installation All commercial dryer installations must conform with local applicable local codes or in the absence of local codes, with the National Fuel Gas Code ANSI Z223.1A-1988. Canadian installations must comply with current standard CAN/CGA-B149(.1 or .2) Installation Code for Gas Burning Appliances or Equipment, and local codes if applicable.

  • Page 23: Dryer Electric, Gas And Venting

    NOTE: The following considerations must be observed for gas dryer installations where dry cleaners are installed. The sources of all makeup air and room ventilation air move- ment 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.
  • Page 24 for the cylinder. When more than two elbows are used, two feet of straight pipe should be removed for each additional elbow. No more than two right angle elbows should be used to exhaust the cylinder. 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.

  • Page 25: Washer Operating Instructions

    WASHER OPERATING INSTRUCTIONS Safety Door Lock This machine is equipped with a Safety Door Lock that locks the door closed from when the cycle is started until the cycle is complete. The door lock prevents opening the door for up to 3 minutes if the power is interrupted during the cycle.

  • Page 26: Dryer Operating Instructions

    Safety Door Lock If power is interrupted the Safety Door Lock delays opening the door until it is safe to do so. If power failure occurs or if power is interrupted during maintenance, it will be necessary to wait 2 to 3 minutes before the door can be opened.
  • Page 27 At that point, the wrinkle free cycle will automatically begin. This cycle will wait two minutes, if the door is not opened or the STOP touch pad switch on the dryer controller is not pressed, and then rotate the cylinder for 10 seconds and stop. This two-minute of idle time and 10 seconds of tumble time will repeat a total of 10 times, at which time the wrinkle free cycle stops.

Gas Valve This L.E.D. is part of the 4-digit numeric display and will be on solid during the drying part of a cycle when the gas valve does not need to be on.
  • Page 38 STOP This touch pad switch will stop the dryer during a dry cycle without clear ing the present drying cycle if pressed once. If pressed and released twice, consecutively, the present dry cycle will be cleared. START This touch pad switch will start the operation of a dry cycle if pressed and released once.
  • Page 39 OPERATING INSTRUCTIONS To dry a load of items, you must choose one of the five-programmed dry cycles. Each of these five dry cycles may be modified in two different ways to match your load. Please, refer to the “Perma- nent Dryer Controller Programming” or “Temporary Dryer Controller Programming” section of this manual. There are two parts to each dry cycle.
  • Page 40 During the dry cycle, either pressing the STOP touch pad switch on the dryer controller or opening the dryer loading door will stop the dry cycle and not clear it. If you press the STOP touch pad switch on the controller and then open the dryer loading door, the dry cycle will not be cleared.
  • Page 41 TEMPORARY DRYER CONTROLLER PROGRAMMING Temporary programming mode will allow the change of the stored dry cycle settings in the dryer controller for one complete dry cycle. After the dry cycle is complete, the default settings that existed be- fore the temporary change are restored. The temporary dry cycle can be stopped and cleared at any time during the dry cycle operation.
  • Page 42 Press and release the SELECT/ENTER touch pad switch on the dryer controller. Once the SELECT/ENTER touch pad switch is pressed and released, the dry time L.E.D. will switch off, the dry cycle L.E.D. and programming L.E.D. will remain on, the temperature L.E.D.
  • Page 43 TEMPORARY DRYER CONTROLLER PROGRAMMING EXAMPLE REQUIREMENTS: Dry a load with 40 minutes of actual heat at 185°F and five minutes of cool down. The following procedure will show you how to temporarily modify the existing dry cycle 1 program for one cycle of drying. It is based on the assumption that the factory defaults have not been permanently changed.
  • Page 44 PERMANENT DRYER CONTROLLER PROGRAMMING The permanent programming mode will allow the change of the stored dry cycle settings in the dryer controller until the operator physically changes them again. The factory default settings can be restored in the dryer controller by pressing the default settings push-button on the back (component) side of the dryer controller circuit board.
  • Page 45 Press and release either the UP or DOWN touch pad switch of the dryer controller to change the drying temperature. Each press and release of either the UP or DOWN touch pad switch will either increase or decrease, respectively, the temperature by five degrees Fahren heit or three degrees Celsius, depending on how your dryer controller is set up.
  • Page 46 PERMANENT DRYER CONTROLLER PROGRAMMING EXAMPLE REQUIREMENTS: Dry a load with 50 minutes of actual heat at 195°F and three minutes of cool down. The following procedure will show you how to permanently modify the existing dry cycle 1 pro- gram for one cycle of drying. It is based on the assumption that the factory defaults have not been per- manently change.

  • Page 51 Air Flow Switch Operation And Adjustment The air flow switch assembly is part of the ignition safety circuit and insures that the burners don’t operate unless there is air flow. When the drive motor and blower are running the flat actuator is pulled in against the back of the dryer closing the switch.
  • Page 52 Ignition System-Function & Sequence During normal dryer operation, the following occurs: 1. The dryer electronic control calls for heat. 2. If the drive motor is running, the blower motor safety circuit provides power to the electronic control. If the control senses that the heat should be on, a circuit is closed allowing power through the high limit thermostat, air flow switch.

  • Page 128: Start Circuit

    Electrical Path Circuit Schematics Start Circuit Power travels into the machine on L1 & L2 & (L3, if 3 phase used). L1 and L2 provide 208- 240VAC to the controls transformer which steps the voltage down to 24VAC for the controls. (The L1 connection at the controls transformer must be checked at start-up to coincide with machine operating voltage) The 24VAC travels out from the transformer on either [X-1 red wire directly to the 1.5 amp fuse] or [X-1 black/red wire to TB-4 and then through the red wire to the 7 amp fuse.

    gent dispenser flushes the detergent into the tub for 20 seconds. This is accomplished when 24VAC travels through the orange wire to the H2 hot water valve solenoid. During the machine fill, a 5VDC signal is sent on the red wire from the P5 connection of the main control PCB to the pressure switch contact and returns on the yellow and orange wires to the P5 connection of the main control PCB.

    Unlock Thermoactuator and Shake Out Circuit 70 seconds before the end of the cycle the main control PCB signals the relay PCB to remove 24VAC from the orange/blue wire at the P-17 connector on the lock thermoactuator. This allows the lock thermoactua- tor time to cool and retract by the end of the cycle.
