- Clean the soap dispenser and lid.
- Check the dra in valve for leaking and that it opens properl y.
- Check the loading door for leaks. Clean the door seal of all foreign matter.
- Leave the loading door open to aerate the washer when not in use.
QUARTERLY
- Make sure the washer is inoperative by switching off the main power supply.
- Check the V-belts for wear and proper tension.
- Clean lint and other foreign matter from around motor.
- Check all water connections for leaks.

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.)

MACHINE MOUNTING DETAIL

PLUMBING
Water supply hoses are furnished with each machine. The threaded connections on the hoses are ¾11 ½ NHT. The small 3/8 ID supply hoses and supplied brass shut off valves connect to the lower
hot and cold valves which flush the soap box. The brass shut off valves can connect to either the
store supply side or the machine inlet side. In case of water splash out due to high water pressure,
adjust brass shut off valves while machine is running until splash out stops. The larger 5/8 ID supply
hoses connect to the upper hot and cold valves.
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)
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 220 volts. Use the
terminal marked “230V” for power supplies between 221 and 240 volts.

INJECTION SOURCE DETAILS
The washer control may be programmed to send 120V output signals for a chemical injection
system. The signals are not intended as a power source and must be limited to less than 100
milliamps of current. 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.
