MOUNTING A concrete pedestal or steel mounting base which elevates the machine approximately 4 - 10 inches (101-250 mm) above the floor level is recommended to provide easy access to the loading door. Allow a minimum of 24 inches (610mm) of clearance behind the rear of the machine, to provide access for motor removal.
Page 19
Mounting Holes : The preceding pages illustrate the mounting dimensions for the machine and also show a typical base construction. Note: Mounting bolts should be checked frequently to insure that they remain tight. The machine should be checked with a spinning load to be sure there is no unusual vibration or movement between the machine and the base or floor...
Page 20
THE PROPER WAY TO INSTALL GROUT! Grout should be installed between base (if used) and concrete floor on all side rails and crossmembers. If using a base you should grout between base top and machine frame and all side rails and crossmembers.

Section 2 Installation & Operation All washers must be installed in accordance with all local, state and national building, electrical, and plumb- ing 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 in turn securely bolted to a substantial concrete floor.
Electrical Dexter single/three-phase 208-240VAC 60 Hz washing machines are intended to be permanently installed appliances. No power cord is provided except 18 lb. (see below). The machine should be connected to an individual branch circuit not shared by lighting or other equipment. The connection should be sheathed in liquid tight flexible conduit, or equivalent, with conductors of the proper size and insulation.
PROGRAMMING INSTRUCTIONS Programming can be accomplished manually using the machine controls or by connecting to the machine control using a PDA (personal digital assistant). For instructions on using a PDA with this washer control, please contact your local Dexter distributor. Please read below for manual programming instructions. The washer has two levels of programming.
Page 37
WATER TEMPERATURE PRICING The washer can be set for different levels of pricing for Cold, Warm and Hot water. The Cold water setting is considered as the base price, which is the normal washer cycle price. Warm Water Price – The next step in the pricing program is to set the additional price for Warm water usage.
Page 38
WASH CYCLE PROGRAMMING To change a feature of the wash cycle, push and hold the Hot temperature button and then push the programming pushbutton on the controller. The Washer mush be in the Idle mode to enter the Wash Cycle Programming mode.

The selected bath LED begins to blink. The display shows the letters “ct” in the left two digits and the bath cycle time in the right two digits. Again the up/down buttons change this value. The range is shown below. If zero time is entered, then the bath will be skipped and the program will return to the bath selection.

Operating Instructions Microprocessor Prior to operation, the micro computer should be set to display the amount of vend price being offered and the cycle to be given to the user. NOTE: Should a power loss occur during cycle and when power returns, P U S H will be displayed in window and customer must push a temperature selection button to continue the cycle.
Section 3 Wiring Schematics 18lb. , 25lb. , 40lb. , 55lb. , 75 lb. V -Series Washer Schematic Start Circuit Power travels into the machine on L1 & L2 & (L3) ( if 3 phase used). 208- 240VAC goes to a Control Transformer ( must be checked at start -up to coincide with machine operating voltage) that steps the voltage down to 115VAC for the controls.
Fill Circuit-Warm S1, S2, S3 and S5 Door Switches are now closed . The green On LED and the Door Lock Solenoid (discussed in Start Circuit) will remain on throughout the cycle. The Lock Thermoactuator receives 115VAC on orange/blue from P17 on main relay PCB and will alternate open and closed keeping the Lock Thermoactuator activated until 1 1/2 minutes before the end of the cycle.
Extract Circuit The Spin LED will illuminate at washer front and the washer controller PCB sends an extract signal to the Variable frequency drive via the data cable at P6 to VFD RJ-11. The rotation as viewed from front during spin will be CCW except 1816 twill BeCW.
Fault# Description Customer Action The door failed to close and lock or The door failed to remain locked during the cycle. Check VFD fault code before turning off .Turn off thepower to the washer. Check wire connections to door /lock switches. Check wire connections from switches to controller.
Page 46
Fault# Description Customer Action Wrong washer size for drive type. Check VFD fault code before turning off power. If the controller was installed in a different size machine before being installed in this machine,a problem can occur. If someone has been doing repairs on the washer, check for the correct size drive.
Page 47
Fault# Description Customer Action The drive size setting has changed. Check VFD fault code before turning off power. Check to ensure all the harnesses are properly connected to the controller. Check to ensure the drive horsepower is proper for this size of washer.
Page 48
Fault# Description Customer Action Overload of the drive or motor (Check drive fault code before powering down) Check VFD fault code before turning off power. Check the washer motor to ensure it turns freely. Check the wiring for loose connections to the drive and motor.
Page 49
Soft Reset of the Main front PCB controller is accomplished by pushing the program button located on the rear of the front controller main PCB, and simultaneously turning power on to machine. This reset will bring Main front controller PCB back to factory default settings. Please record any modified information that has been inserted in memory before attempting to Soft Reset the PCB.

Possible controller problem CE2- Illegal data address, VFD received an address not available to the controller. CE3- Illegal data value received at VFD.
Before performing any service work, remove electrical power from the machine. Always replace panels before putting machine into service. Top Panel Removal A. Remove 4 screws that hold detergent dispenser to top panel. B. Unlock top panel lock. C. Raise top panel, slide to the rear to release from back clips and lift off. Detergent Dispenser Remove top panel to access dispenser.
Page 53
DELTA Variable Ferquency Drive POWER: Mains power is connected to terminals L1, L2, and L3 on the Delta drive. If the washer is connected to a three phase source, there should be voltage present on all three terminals. If the washer is connected to single phase power, there should be voltage present on terminals L1 and L2.
Circuit Breaker/Fuse The fuse (optional circuit breaker) mounts to the rear channel. It carries all of the controls in the machine but does not include the motor. To reset the circuit breaker just push in the button.If you have a fuse then remove fuse holder and fuse and replace with a 11/2 amp fast blow type fuse on most models and 2.5 amp used for 75 lb model.
Controls Transformer This transformer is mounted at the back of the control trough and steps a range of 208 to 240 volts down to 115 volts for the controls. There are two terminals on the controls transformer for incoming power. One terminal tap is marked for 208 volts use this tap for measured voltage of 200 volts - 216 volts.
Masking Ring (door lock cover) Removal A. Remove front panel. B. Remove nuts that retain masking ring. C. Move it to the left and off. Door Lock Assembly After removing the front panel and trim ring, the door lock assembly can now be accessed. Operation After loading the clothing, the door should be closed and latched.
