Installation & Operation
All washers must be installed in accordance with all local, state and national building,
electrical, and plumbing codes in eect in the area.
Foundation Requirements
The washer must be securely bolted to a substantial concrete oor, or mounted upon a suitable base
which is in turn securely bolted to a substantial concrete oor. Care must be stressed with all foundation
work to insure a stable unit, eliminating vibration. All installations must be made on sound concrete oors.
See mounting dimensions for each model being installed.
Mounting
A concrete pad or steel base which elevates the machine 4 to 6 inches above the oor level. To provide
easy access to the loading door, it is recommended to allow a minimum of 24” of clearance behind the
rear of the machine for service as is shown. Dexter highly recommends the use of a dry expansion grout
mix.
Proper Machine Grout Installation
Grout should be installed between base (if used) and concrete oor 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.
(Grouting between the machine base and the oor is absolutely required for all 200G Express Models)
Mounting Holes
See mounting dimensions for the machine model you are installing in previous section. They also show a
typical concrete pad arrangement. It is highly recommended that you use all mounting holes supplied with
each model. 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 oor. Please note: Machine grouting is highly recommended as
grouting insures stability and longevity.
Plumbing
Water supply hoses are furnished with each machine. The threaded connections on the hoses are
standard garden hose type thread. Separate hot and cold water lines with shut o valves or faucets for
inlet hose connections must be provided, maintaining 30 to 120 p.s.i. water ow pressure. Maximum water
temperature is 180 degrees.
Drain
The drain outlet tube at the rear of the machine is 3” in outside diameter on models T-400, T450, & T-600.
The drain outlet tube at the rear of the machine is 2 1/4” outside diameter on a T-300 and T350 models.
All Drains are gravity Drain. Adequate fall must be maintained for proper drainage.
Protective Film
The machine may have protective adhesive lm on the front escutcheon area and the front and side
stainless steel panels. The lm may be peeled o before putting the machine into service.
Electrical
Dexter single/three-phase 208-240VAC 60 Hz washing machines are intended to be permanently installed
appliances. No power cord is provided. 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 exible
conduit, or equivalent, with conductors of the proper size and insulation. A qualied technician should
make such connections in accordance with the wiring diagram.
T-300 WCAD20KCS-10 model (1 phase 120 volts) washers are equipped with an electrical cord with a 3
prong grounded plug. A U.L. approved receptacle, which has been properly grounded in accordance with
local electrical codes must be used with the machine. Each unit should be connected to an individual
branch circuit not shared by lighting or other equipment. Conductors of the proper size and insulation
(suggested size below) should be used.

Disconnect all power to the washer. Remove screw and lift out 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. It is highly recommended to use a TVSS.
• If power is 208-240-1PH-60Hz, connect L1, L2 and Ground. If power is 120 -1PH-60Hz. Use a
UL approved receptacle with proper external ground.
NOTE: It is important that the grounding screw next to the power terminal
block TB-1 be connected to a good external ground.
Controls Transformer
The controls transformer is located inside the control trough and steps a range of 208 to 240 volts down
to 115 volts. There are two terminals on the controls transformer for the primary (incoming) power.
Use the terminal marked “208V” for power supplies between 200 and 215 volts. Use the terminal
marked “230V” for power supplies between 216 and 240 volts.
NOTE: transformer must be set at proper tap for proper operation.
Electrical Connections
Electrical power connections are made to the small terminal block located in the rear of the control
trough. The terminal block is accessed by opening the top panel of the machine.
• 1 Phase or 3 Phase connections
• 208-240 volts, 60 Hz.
• 3 wire plus ground
• Suggested Minimum Wire Size -- 12 Ga.
Fusing Requirements:
Dual element time delay fuse or equivalent breaker of amperage
specied below.
• 1 Phase or 3 Phase 15 amp , 208-240v
• WCAD-20-12, WCAD20-12SZ, WCAD-30-12,

WARNING
Always disconnect electrical power to the
machine before performing any adjustments
or service.
Emergency Stop / 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.
The Emergency Stop button pauses the washer and
allows the door to be opened during the cycle after the
Safety Door Lock releases. When the Emergency Stop
button is pressed an alarm will sound and the display
will begin counting down from “3”. If the button is
released before 3 seconds elapse, the alarm will stop
and the cycle will continue normally. If the Emergency
Stop is held down for 3 seconds, the display will
count down to “0” and the washer will begin stopping
movement and water ow and begin draining water from inside the washer. Though the machine may
stop wash movement quickly, it may take up to 3 minutes for the door to unlock. During that time the
alarm will continue to sound. When the alarm stops, the door may be opened. The washer may be
restarted by closing and latching the door, and pressing the Start button. If the washer was stopped
during nal extract, the cycle will be ended. If the washer is stopped for more than 1 hour, the cycle
will be terminated. If the emergency stop is triggered a second time during the cycle, the cycle will be
terminated.

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. The Washer Cycle
Programming allows the owner complete access to the wash cycle
parameters: add/remove a bath, bath times, spin times, water
temperatures, etc. The Coin/Price Programming allows the owner to
set the price for the washer features and the values of the coins. To enter the programming modes, the
top of the washer must be unlocked and slid toward the back of the washer a few inches.
Coin Price Programming
While the washer is in the Idle mode, push the Programming pushbutton on the controller. The Idle
mode is when the washer is not running a cycle and the price of the bath is displayed. The Programming

TRANSIENT VOLTAGE SURGE SUPPRESSORS
Like most electrical equipment your new machine can be damaged or have its life shortened by voltage
surges due to lightning strikes which are not covered by factory warranty. Local power distribution
problems also can be detrimental to the life of electrical components. We recommend the installation of
transient voltage surge suppressors for your new equipment. These devices may be placed at the power
supply panel for the complete installation and don’t require and individual device for each machine.
These surge protectors help to protect equipment from large spikes and also from small ongoing spikes
in the power that occur on a day to day basis. These smaller surges can shorten overall life of electrical
components of all types and cause their failure at a later date. Although they can’t protect against all
events, these protective devices have a good reputation for signicantly lengthening the useful life of
electronic components.
Electronic Components are helped to have a longer useful life when they are supplied with the clean
stable electrical power they like.
We are including the following names and links to a few suppliers of these devices for those who don’t
currenty have a source.
