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.

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.

OPL Washer Cycle Parameter Ranges
The range of each cycle parameter is shown below:
Bath Cycle Time “ct”
0 to 15 minutes for Prewash, Rinse1 and Rinse 3 to 15 minutes for Wash and Final Rinse. For the
baths that can, if the time is set to zero, then that bath will be eliminated from the cycle.
Bath Water Temperature “t”
HH – hot, CH – warm, CC – cold, EE – no water. The owner can set the bath default. For the wash
bath, the default is over ridden for that cycle by the customer when the temperature is selected.
Bath Water Level “L”
Water Level, Lo for low, Hl for high.
Bath Delay Fill “dF”
The selections are “d” for delay the bath time until water level is reached or “t” for decrement bath
time during the ll.
Bath Spin Time “S”
0 to 10 minutes for Prewash, Wash, Rinse1 and Rinse2, 1 to 10 minutes for Final Spin.
Bath “IS”
The owner can change the displayed value, 0 thru 6. Codes for injections sources are dened at
the end of the programming section. When the No Water bath is selected, the electronic controller
prohibits injection signals. The programmed injection source value is ignored.

Washer Programming Instructions
THERE ARE TWO WAYS TO MODIFY PROGRAMMING OF THE V-SERIES OPL SIX (6)
PREPROGRAMMED FORMULAS
Option 1: 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 and software, please contact your local Dexter distributor. Please read below for manual
programming instructions.
The keypad layout for the washer control is shown below.
Option 2: Wash Cycle Manually Programming
1. Turn on the power to the washer.
2. Turn the Run/Program key to the Program position. Display will show
“CO” and the “ADD BLEACH” will blink and will continue to blink
during the programming mode.
3. Press the “DOWN” or “UP” buttons to select which cycle to alter. When
the desired cycle number is displayed, press “START”.
4. The display should now show a “b”. The “b” and the cycle indicator
lights indicate which bath is being selected to alter. Press the “UP”
and “DOWN” buttons to select a bath to change and then press
“START”.
The indicator lights are shown above:
When “RINSE” is selected, “b r1” through “b r4” may be selected.
There may be multiple rinses that are indicated by br 1, br 2, br 3, and br 4
5. Each bath can be programmed with the following options. Use the “DOWN” and
“UP” keys to select the desired setting and the “START” key to move to the
next option.
To exit the programming of a bath, press the “STOP” button once and use the “UP” and “DOWN”

Rapid Advance Mode
To enter the Rapid Advance mode, turn the key CCW. The Rapid Advance setting is not marked next to
the key, but turning the CCW until it stops selects this mode. The Rapid Advance mode can be entered
from either the Idle mode or during the cycle. If the cycle has not yet started, press the “START” button.
To rapid advance to the next step in the wash cycle, push both the “UP” and “START” buttons at the same
time. The display will show an “Ad” (advance) in the display. The washer will advance to the next bath
segment. The water will drain before the advance will occur and the time displayed may not be accurate.
Notes: - The indicator lights will show to which segment the cycle has been advanced.
- The cycle will continue in rapid advance mode even if the key is turned to “RUN” and/
or removed.
- Rapid advance cannot skip the final 1- minute tumble of the cycle, and the door
lock may remain activated for up to 3 minutes after the cycle has been completed.
- Chemical 120 volt signals will be lost after Rapid advance Mode has been activated
until cycle resets. To exit the Rapid Advance mode, push and hold the STOP button.
Injection Source Details
The washer control may be programmed to send
output signals for a chemical injection system.
There is a separate terminal block for connection
of the external injection signals. For the injection
sources, program codes 0 through 6 are as shown
in the table below. Injection signal will trigger a 120
volt reading at rear terminal block for approximately
5-10 seconds and will start to trigger at about 10- 15
seconds
after start of ll bath.
