WARNING - THIS WASHER IS EQUIPPED WITH DEVICES AND FEATURES RELATING TO ITS

SAFE OPERATION. TO AVOID INJURY OR ELECTRICAL SHOCK, DO NOT PERFORM
ANY SERVICING UNLESS QUALIFIED TO DO SO.

IT IS THE RESPONSIBILITY OF THE OWNER TO CHECK THIS EQUIPMENT ON A
FREQUENT BASIS TO ASSURE ITS SAFE OPERATION.

A machine should not be allowed to operate if any of the following occur:

• Excessively high water level.

• If machine is not connected to a properly grounded circuit.

• If the door does not remain securely locked during the entire cycle.

• Vibration or shaking from an inadequate mounting or foundation.

WARNING - FOR SAFETY

1. Always shut off power and water supply and wait a minimum of one minute
before servicing.

2. Do not overload the washer.

3. Do not bypass any safety devices of this washer.

4. Do not use volatile or flammable substances in or near this washer.

5. Do not attempt to open door when cylinder is in motion, or when it contains
water.

6. Keep all panels in place. They protect against shock and injury, and add
rigidity to the washer.

INSTALLATION INSTRUCTIONS

All washers must be installed in accordance with all local, state, and

WARNING - THESE INSTALLATION AND SERVICING INSTRUCTIONS ARE FOR
USE BY QUALIFIED PERSONNEL ONLY. TO AVOID INJURY AND ELECTRIC
SHOCK, DO NOT PERFORM ANY SERVICING UNLESS QUALIFIED.

national building, electrical, plumbing and other codes in effect.

FOUNDATION REQUIREMENTS

This machine is designed for use on or over bare concrete floor - not to be
used above combustible flooring. 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. CARE MUST BE STRESSED WITH
ALL FOUNDATION WORK TO INSURE A STABLE UNIT INSTALLATION, ELIMINATING
POSSIBILITIES OF EXCESSIVE VIBRATION. All installations must be made on sound
concrete floors, 8" or thicker. Anchor bolts must be of a quality grade, and a
minimum of 3/4" diameter. Six (6) mounting bolts must be used.

MOUNTING

A concrete pedestal, or steel mounting base which elevates the machine a
MAXIMUM of 10" above the floor level is recommended to provide easy access to
the loading door. Actual base height should be determined by application,
considering access to loading door, access to soap dispenser and height of
loading carts. Allow a minimum of 24" of clearance behind the rear of the
machine, to provide access for motor removal. Refer to Figure 1-1 and 1-2 for
machine bolt-down dimensions. Refer to Figure 2 for overall washer dimensions.

If an elevated concrete pedestal is desired, it should be embedded into the
existing floor. Anchor bolts should be 3/4" x 8", grade 8 or better, headed by
a 4 inch square fish plate, and should protrude 2 ½ inches above the finished
surface of the pedestal. If anchors are to be installed in existing concrete
we recommend Hilti Adhesive Anchor System with Hilti HEA 3/4-6 5/8 Adhesive
Capsules and Hilti HAS 3/4-9 5/8 Super Rods. (For more information, contact
Hilti Customer Service at 1-800-879-8000). EXPANSION ANCHORS ARE NOT
RECOMMENDED FOR USE IN CONCRETE FLOORS OR PEDESTALS. (See Figures 1-1 and 1-

3.)

PLUMBING

Water supply hoses are furnished with each machine. The threaded connections
on the hoses are 3/4-11 ½ NHT.

Separate hot and cold water lines must be provided, maintaining 30 PSI to 120
PSI water flow pressure.

DRAIN

The drain outlet tube at the rear of the machine is 3 inches in diameter. Any
drain hose used must be lower than the drain valve to assure proper draining

╚════════════════════════════════════════════════════════════════════╝

Dexter T1200 washing machines are intended to be permanently installed
appliances. 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. No power cord is provided. Such connections should be
made by a qualified electrician, in accordance with the wiring diagram.

FUSING REQUIREMENTS

20 Amp Time Delay (Dual Element) Fuse(s) (or equivalent circuit breaker).

TO MAKE ELECTRICAL CONNECTIONS:

Remove screw and lift out cover located on upper left of machine (viewed from
back).

Figure 3 - Electrical Power Connections. 208-240 VAC, 1 or 3 Phase, 60 Hertz

If power is 208-240-3PH-60HZ
connect L1, L2, L3 and ground.
(If there is a high phase it
must be connected to L3.)

If power is 208-240-1PH-60HZ
connect L1, L2 and ground.

IMPORTANT

FOR SAFETY AND PROPER EQUIPMENT
OPERATION THE GROUND LUG MUST
BE CONNECTED TO A GOOD EXTERNAL
GROUND.

CHEMICAL INJECTION

Dexter T1200 washing machines are intended to be permanently installed
appliances. The machine is intended to have a chemical injection system
operating with it. There are convenient electrical connection points for the
injection pumps shown in Figure 3. Up to four (4) independent pumps can be
controlled through the signals A, B, C and D. The injection pump signals are
24 VAC. The COM shown in Figure 3 is the common or return for these injection
signals.

The four injection pump signals, (A, B, C and D) are individually selected, or
in combinations, by the programming within the selected cycle. The recommended
signal connections are shown in Figure 4. The selection of the signal is
explained in the Programming Instructions section of this manual.

FIGURE 4 - INJECTION SOURCE SIGNALS AND CONNECTION RECOMMENDATION

CHEMICAL INJECTION HOSES

Chemical injection hoses are to be inserted into the injection inlet at the
upper right rear of the washer. These hoses should be inserted into the round
PVC pipe a minimum of 14" and a maximum of 18" to eliminate chemical buildup in
the pipe and/or restrict water flow to the tub. Secure the hoses as required.

FINAL CHECKOUT

After all mounting, plumbing and electrical work is completed, the washer
should be checked for water leaks, and proper functioning by first running each
step in the diagnostic cycle, (cycle #31), and by running a complete cycle.

Scroll Up increases the cycle number displayed by one each time the switch is
depressed. When the Scroll Up is held, the display cycle numbers will continue
to increase until cycle #30, (cycle #31 in Programming Mode), is reached, at
which time the cycle number displayed will rollover back to cycle #1.

SCROLL DOWN ARROW (BLUE) Push-button - Depress momentarily/depress and hold.

Scroll Down decreases the cycle number displayed by one each time the switch is
depressed. When the Scroll Up is held, the display cycle numbers will continue
to decrease until cycle #1 is reached, at which time the cycle number displayed
will rollover to cycle #30, (cycle #31 in Programming Mode).
