NOTE: Component failure due to dry cleaning solvent fumes will VOID THE WARRANTY.

  • Page 17: Exhaust Requirements

    E. EXHAUST REQUIREMENTS Exhaust duct work should be designed and installed by a qualified professional. Improperly sized duct work 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-heat thermostats.
  • Page 18 NOTE: When the exhaust duct work 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. To protect the outside end of the horizontal duct work from the weather, a 90º...

  • Page 28 WARNING: NEVER TEST FOR LEAKS WITH A FLAME!!! IMPORTANT: The dryer and its individual shutoff valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psig (3.5 kPa). NOTE: The dryer must be isolated from the gas supply piping system by closing its individual manual shutoff valve during any pressure test of the gas supply system at test pressures equal to or less than 1/2 psig (3.5 kPa).

  • Page 29: Preparation For Operation

    H. PREPARATION FOR OPERATION 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. Check incoming supply voltage to be sure that it is the same as indicated on the dryer’s data label affixed on the back of the dryer control (service) door.
  • Page 30 4) Open main door to stop the dryer, and change selection to “PERM PRESS” (medium) setting. Repeat this procedure, but change the selection (setting) to “HI” (high). This will confirm that setting key circuits and door switch circuits are functioning properly. 5) Repeat above procedure for the other basket (tumbler).

  • Page 31: Shut Down Instructions

    4. Make a complete operational check of ALL safety-related circuits (i.e., door switches, hi-limit thermostats, sail switches, basket [tumbler] safety thermostats, etc.). NOTE: The sail switch can be checked for proper operation by opening the control door while the dryer is running and the heating unit (burner) active (on). The heating unit(s) should shut off within a few seconds.

  • Page 32: Operating Instructions

    OPERATING INSTRUCTIONS A. STARTING THE DRYER The dryer is available for use when the appropriate microprocessor controller (computer) light emitting diode (L.E.D.) display reads “FILL” and/or the amount needed to start the dryer (i.e., “25”). Once the load has been put into the dryer and the main door is closed, start the dryer as follows: 1.
  • Page 33 NOTE: When a cycle is interrupted by opening the main door, the cycle time will continue to count downward, regardless if the door is open or closed until a keyboard (touch pad) selection is made. 2) Selection (setting) changes can be made at any time during the drying cycle by opening and closing the main door and then making a new selection.
