Washer and Dryer

Installation

& Operating

Instructions

20

Washer Installation

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 securely bolted and machine grouted 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 8” or thicker. Anchor bolts must be of a quality grade and at least imbedded at minimum

of 5” in length and minimum 3/4” diameter.

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 space. SIX (6) bolts are required to mount the washer to the steel base or

concrete pad. Grouting where base or machine makes contact with concrete is REQUIRED to achieve

100% surface contact and for warranty to be honored.

Note: Premanufactured bases are available from DEXTER factory (see sales dept.)

Mounting Bolts

The previous pages illustrate the mounting dimensions for the machine and also show a typical concrete

pad arrangement.

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.

Proper Machine Grout Required Installation

Machine grout must be installed between base (if used) and concrete oor on all side rails and crossmem-

bers. If using a base you must grout between base top and machine frame and all side rails and cross-

members.

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.

Drain

The drain outlet tube at the rear of the machine is 3” outside diameter on models. Adequate fall for this

gravity drain 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.

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.
