INSTALLATION INSTRUCTIONS

All washers must be installed in accordance with all local, state and national building,
electrical, plumbing and other codes in effect in the area.

WARNING - THESE INSTALLATION AND SERVICING INSTRUCTIONS
ARE FOR USE BY QUALIFIED PERSONNEL ONLY. TO AVOID INJURY
AND ELECTRICAL SHOCK DO NOT PERFORM ANY SERVICING
OTHER THAN THAT CONTAINED IN THE OPERATING
INSTRUCTIONS, UNLESS QUALIFIED.

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 and grouted to a substantial concrete floor, or
mounted and grouted upon a suitable base that is securely bolted and grouted 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 inches (203 mm) or
thicker. Anchor bolts or expansion anchors must be of a quality grade and a minimum of 3/4-inch
(19 mm) diameter. Six bolts are required to mount the washer to the steel base or concrete pad.

MOUNTING

A concrete pedestal or steel-mounting base that elevates the machine approximately 4 inches (102
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. Refer to Fig. 1-1 and 1-2 for machine bolt-down dimensions.

If an elevated concrete pedestal is desired, it should be embedded into the existing floor. Anchor
bolts should be 3/4" x 8" (19 mm x 200 mm), grade 8 or better, headed by a 4 inch (10 cm) square
fish plate and should protrude 2 1/2” (64 mm) above the finished surface of the pedestal.
EXPANSION ANCHORS ARE NOT RECOMMENDED FOR USE IN CONCRETE PEDESTALS,
BECAUSE THE ANCHORS ARE TOO CLOSE TO AN EDGE, CAUSING IT TO BREAK OUT.
(See Fig. 1-1 and 1-3.)

PLUMBING

Water supply hoses are furnished with each machine. The threaded connections on the hoses are ¾-11
½ NHT.

Separate hot and cold water lines must be provided, maintaining 30 psi to 120 psi (207 kPa to 827
kPa) water flow pressure. A 140F (60C) degree hot water supply is recommended for best washing
results.

DRAIN

The drain outlet tube at the rear of the machine is 3 inches (76 mm) in diameter. Any drain hose used
must be lower than the drain valve to assure proper draining.

ELECTRICAL

WARNING

SHUT OFF POWER AND WATER BEFORE OPENING ANY SERVICE PANELS.

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 flexible conduit, or equivalent, with conductors of the proper size and insulation. A qualified
technician should make such connections in accordance with the wiring diagram. (Suggest a minimum
wire size of 12 ga.)

TO MAKE ELECTRICAL CONNECTIONS: 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.

 If power is 208-240-1PH-60Hz, connect L1, L2 and Ground.

NOTE: It is important that the grounding screw next to the power terminal block TB-1 be connected
to a good external ground.

FUSING REQUIREMENTS:

SINGLE- and THREE -PHASE MODELS - 20 AMP TIME-DELAY (DUAL ELEMENT)
FUSE (or equivalent circuit breaker). *

*Note: For elevations above 6600 feet or very hot climates, a 30 amp breaker is recommended due
to down-rating of circuit breakers under these conditions.

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 208 and 215 volts. Use the terminal
marked “230V” for power supplies between 216 and 240 volts.

CHECKOUT

After all mounting, plumbing and electrical work is completed, the washer should be run through a
cycle and checked for water leaks and proper functioning.

STARTING THE WASHER

A. Load the clothes into the cylinder and latch the door securely. Be sure clothing does not
get caught between the door gasket and tub front when closing the door. Maximum load is
60 pounds clothes, dry weight. Do not load the washer with more than 60 lbs.

B. Select the appropriate cycle temperatures for the load being washed.

C. Add low sudsing powdered detergent into the “detergent” compartment of the automatic
dispenser on the front of the washer. If desired add fabric softener to the “fabric softener”
compartment. Use the amount of fabric softener as recommended by the manufacturer.

If liquid wash products are used in the “detergent” compartment, they must be added at
the beginning of the wash cycle.

If the machine is set for pre-wash, washing products can be added to dispenser or put in with
the clothes when loading the washing machine.

D. Insert coins, tokens or debit card to meet the displayed vend price. Once the vend price is

met, the display will read “PUSH” and the start button LED will blink. If the door is not
closed and latched, the display will read “DOOR” and the control will wait until the door
is latched to continue. Pressing the start button will begin the cycle and activate the ON
light. The display will go blank for a moment and then display the cycle time in minutes.
The clothes door will lock and remain locked until the end of the cycle.

END OF CYCLE

When the cycle is complete the time will display “0” until the door is opened and a 5-second tone
will sound. The door can now be opened. Leave the clothes door open when the machine is not in
use.
