Machine
Installation
& Operating
Instructions

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. 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.
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 fahrenheit.
Drain
The drain outlet tube at the rear of the machine is 3” in outside diameter on models T-600, T-900, T-1200.
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.
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.
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.
