    INTRODUCTION C AUT I O N W ARNIN G D ANG E R These symbols alert reader to situations that could cause personal injury, and are shown here in increasing levels of hazard seriousness. W AR NI NG Do not store or use gasoline or other flammable vapors and liquids in the vicinity of this or any other appliance.
  • Page 6 IMPORTANT: During the lifetime of the ironer, it will require service. The information contained in the manuals is written and intended for use by qualified service technicians who are familiar with the safety procedures required in the repair of your ironer, and who are equipped with the proper tools and testing equipment.

  • Page 8: Important Installation Instructions

    Trained, qualified personnel must perform all operation, maintenance, and repair of the flatwork ironer only. Adequate lighting, operating, and shutdown instructions must be provided, and all operating and supervising personnel must be thoroughly instructed in safe operating practices. IMPORTANT INSTALLATION INSTRUCTIONS 1.

The right frame contains the drive system. 26) Folding Conveyor: The conveyor that oscillates to fold the flatwork. 27) Intermediate Conveyor: The conveyor or pinch rolls that suspend the flatwork above the folding conveyor so that it may be folded.

  • Page 12: Start Up And Shut Down Procedures

    START UP AND SHUT DOWN PROCEDURES These procedures should be used at all times to properly start and stop the ironer. SHUT DOWN To obtain long life and reliability from the flatwork ironer, use the following procedures when shutting down the machine. 1.

  • Page 13: Elec T R Ic A Lly Heated Model

    ELECTRIC HEATED 1. Check that the circuit breaker for the ironer is turned on; then press the start button to energize the drive system, vent system blower motor (if equipped), and the electric heating elements. NOTE: Heat build-up can shorten flatwork ironer life if allowed to continue. Keep machine busy to avoid prolonged heat build-up.

    Table 2-2 Problem: Flatwork does not properly iron or dry. 1. Is heated cylinder temperature correct? Consult Operation Manual for suggested operating temperatures. 2. Has flatwork excessive moisture? Increase extraction time or pre-dry flatwork. Is flatwork too dry? Reduce dryer conditioning time because to properly iron flatwork (just like hand ironing), heat, pressure, and moisture are required.

    2. Check if wire connection from thermostat to system control (module) 25V is correct. Check if 2A fuse of module is blown. Secure ignition cable. 3. Start machine and turn on thermostat. Check if spark is generated if not, replace system control (module).

    6. Check heating elements. Disconnect power and check each element with a continuity tester (no continuity indicates a bad element). Replace any defective element(s). Table 2-9 Problem: Electrically Heated Model generates excessive heat. 1. Check the vent and airflow situation. Is there something restricting the airflow? Is the blower motor working properly? Is the exit CFM the same as the blower? Is machine vented independently? (See Table 2-4, #1).

    1. Feed ribbons may have shrunk due to moisture in the linen or laundry room. Adjust (loosen) feed ribbon drive roll (on both sides). If feed ribbons appear too loose later, adjust (tighten) feed ribbon drive roll back. However, do not overtighten. NOTE: take measurements on both sides of roll to assure equal distance on ribbons.

    3-2 RETURN RIBBON REPLACEMENT (Figure 3-2) Replace return ribbon when fraying, stretching, or slipping of one or more ribbons becomes evident. NOTE: Feed, return, and conveyor ribbons will stretch during use. To avoid creating an uneven strain on the conveyor rolls and breaking the new ribbons, the first replacement of these ribbons as a set is recommended.

    W ARNING Do not operate gas-heated ironers without a canopy blower. Operation of gas machines without a canopy can cause deadly gases to flow into the operator’s area. The ironer vent must not be shared with other equipment. Adequate make up air for operator breathing must be provided to replace the air removed by the exhaust blower.

    8. Start up the machine using the procedure outlined in the Introduction. Check all steam lines and the rotary pressure joint using soap and water solution painted on all con- nections. If no leaks are present, normal operation can be resumed. 3-9 HEATER ELEMENT REPLACEMENT (Electric Model Only) (See Figure 3-5) The electrically heated flatwork ironer is equipped with 3, 4, or 9 tubular radiant elements, depending upon model.

    Figure 3-5 3-10 FOLDER OPERATION (Models With Built-In Folder Only) 16”, 20”, and 24” Model: A folding and transfer conveyor provide a primary accordion fold that is 18” (46 cm) wide. The folding conveyor is driven by clutches, which are connected by roller chain and sprockets, to the main drive system.

  • Page 35: Clutches

    The Finish Master folds the flatwork one piece at a time. The flatwork is discharged from the ironer section onto the folding conveyor by the return ribbons. As the flatwork leaves the transfer conveyor and falls onto the folding conveyor, signal switches are activated which energize the switches located at each end of the folding conveyor.

SPARK GENERATOR POWERED Main valve operators open. If no spark, control module goes into lockout after timing period. System must be reset.
  • Page 40 b) Start System 1. Turn on the power and the gas supply. 2. Set thermostat to call for heat and watch for spark at the igniter. Time the length of the spark operation; it must be within 15 seconds. 3. Check that the system starts as follows: Spark turns on, gas valve opens at once, and burner ignites after gas reaches the main burner.
  • Page 41 d) Make certain that all wiring connections are clean and tight. e) Check ceramic insulator on flame sensor or spark igniter. A cracked insulator will allow current to leak to ground. Replace device if insulator is cracked. f) Check the flame sensor and its mounting bracket. Correct the position if bent out of shape.

    2. Restart the system and read the meter. The flame sensor circuit must be at least 1.5 uA and steady. If the reading is less than 1.5 uA or unsteady, see Low or Unsteady Flame Current section below. d) Low or Unsteady Flame Current If the current to the control module is less than 1.5 uA or is unsteady, check the burner flame and flame sensor location and electrical connections as follows: 1.

  • Page 44 C AU TIO N 1. Shut off gas during installation. Turn off main gas supply and wait for unburned gas to vent. 2. Disconnect power supply before connecting wiring to prevent electrical shock or equipment damage. 3. Do not remove seal over control inlet or outlet until ready to connect piping. 4.

  • Page 45: Startup And Checkout

    c) Wiring Follow circuit diagram provided by appliance manufacturer. Disconnect power supply before making wiring connections to prevent electrical shock or equipment damage. All wiring must comply with local electrical codes and ordinances. Never apply a jumper across (or short) the valve coil terminals, even temporarily (Figure 3-12). This may burn out fuse in control module or heat anticipator in thermostat.
