  • Page 24 Allow a minimum 24 inches (610 mm) of clearance behind the rear of the machine to provide access for motor service. Contact a Dexter laundry equipment distributor for recommended steel mounting bases. If an elevated concrete pedestal is desired, it should be embedded into the existing floor. See Machine Mounting Detail Figures for floor thickness and bolt sizes.
  • Page 25 If power is 400V-3PH-50Hz, connect L1, L2, L3, N, and Earth. If there is a high leg, it must NOT be connected to L1 or L2. However, failure due to a voltage surge on the high leg is not covered by equipment warranty. Contact Dexter Laundry with any questions. (Only Heated Washers may be connected to 400V-3PH power).
  • Page 26 60 HZ CONTROL TRANSFORMER CONNECTIONS NOTE: transformer must be set at proper tap for proper operation. The controls transformer is located inside the control trough and steps a range of 208 to 240 volts down to 115VAC and 24VAC. There are two terminals on the controls transformer for the primary (incoming) power.
  • Page 27 INJECTION SOURCE CONNECTIONS The washer control may be programmed to send ten 120VAC output signals for 60Hz models (or 24VAC for 50Hz) for a chemical injection system. The signals are not intended as a power source and must be limited to less than 100 milliamps of current. There is a separate terminal block for connection of the external injection signals.
  • Page 28 OPERATING INSTRUCTIONS STARTING THE WASHER 1) Turn on power to the washer. A)Load the laundry. Place laundry into the cylinder and latch the door securely. Be sure laundry does not get caught between the door gasket and tub front when closing the door. Maximum load is the dry weight capacity listed in the specification sheet.
  • Page 29 EMERGENCY STOP / SAFETY DOOR LOCK This machine is equipped with a safety door lock that locks the door 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 30 Injection Source Details Detergent Measurements The washer control may be programmed to send output By Washer Model signals for a chemical injection system. There is a separate terminal block for connection of the external injection sig- nals. For the injection sources, program codes 0 through 6 are as shown in the table below.

  • Page 72: Start Circuit

    Electrical Path Circuit Schematics Start Circuit Power travels into the machine on L1, L2, and (L3 if 3 phase used). Power from the L1 & L2 supplies power to the 12VDC power supply. This power being sent to the Control PCB. 115VAC, 24VAC, and the VAC Neutral is cre- ated by the control transformer.

  • Page 73: Fill Circuit

    Agitation Circuit When the 12VDC signal closes the K5 in the Control PCB it closes the loop in the yellow wire from the VFD terminal MI6 back to the DCM on the white/yellow through the stop button. This enables the Drive to operate and allow motion.

  • Page 74: Extract Circuit

    Level Achieved / Stage Completion / Drain When the water level in the basket reaches the preset level pressure, the switch moves it's switch contacts to the full or closed position. This causes the main control PCB to signal the relay PCB to shut off the water valve coils.
