Installation & Operation
All washers must be installed in accordance with all local, state, and national building, electrical, and
plumbing codes that are in effect in the area.
Foundation Requirements
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, eliminating vibration. All installations must be made on sound concrete floors.
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 floor 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. 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 floor 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.
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 floor. 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 off valves or faucets for
inlet hose connections must be provided, maintaining 30 to 120 p.s.i. water flow pressure. Maximum water
temperature is 180 degrees fahrenheit.
Drain
The drain outlet tube at the rear of the machine is 3” in outside diameter on models T-650, T-950, T-1450.
Adequate fall must be maintained for proper drainage.
Protective Film
The machine may have protective adhesive film on the front escutcheon area and the front and side
stainless steel panels. The film may be peeled off 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 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. 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 should be used.
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. It is highly recommended to use a TVSS.
• If power is 208-240-1PH-60Hz, connect L1, L2 and Ground.
Note: 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: L1 on the 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 machine.
The terminal block is accessed by removing the access cover.
• 1 Phase or 3 Phase connections
• 208-240 volts, 60 Hz.
• 2 or 3 wire plus ground
• Suggested Minimum Wire Size -- 12 Ga.
• Suggested Minimum Wire Size -- 10 Ga
T-1450
Fusing Requirements:
Dual element time delay fuse or equivalent breaker of
amperage specified below.
• 1 Phase or 3 Phase 15 amp
• T-650
• 1 Phase or 3 Phase 20 amp
• T-950
• 1 Phase or 3 Phase 30 amp
• T-1450
Rotation in extract as viewed through glass door at front of washer models will be counter-clockwise
WARNING
Always disconnect electrical power to the
machine before performing any adjustments
or
service.
