All washers must be installed in accordance with all local, state and national building, electrical, and plumbing codes 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 4” or thicker but see mounting dimensions for each model being installed.
Mounting
A concrete pedestal or steel mounting base which elevates the machine approximately 4 - 10 inches (101-250 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. If using Dexter bases, please make sure to use bevel washers when mounting machine to base. Bevel washers can be purchased through the Dexter Parts Department.
Proper Machine Grout Installation
Mix with water to a consistency that is easy to work with. Grout should be installed between base (if used) and concrete floor on all side rails and crossmembers. If using a base you must grout between base top and machine frame all side rails and crossmembers.
Mounting Holes
The following pages illustrate the mounting dimensions for the machine and also show a typical base construction. 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.
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 200 degrees.
Drain
The drain outlet tube at the rear of the machine is 3” in outside diameter on models T-400, T-600, T-900, T-1200. A flexible hose (# 9242-417-003) is available to extend the drain system for these models. A drain outlet tube at the rear of the machine is 2 1/4” outside diameter on a T-300. model. A flexible hose ( #9242-417-001) is available to extend the drain system for these models. 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.
T-300 WCVD18HCS-10 model (1 phase 120 volts) washers are equipped with an electrical cord with a 3 prong grounded plug. 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.
• If power is 208-240-1PH-60Hz, connect L1, L2 and Ground. If power is 120 -1PH-60Hz. 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: 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 control trough. The terminal block is accessed by opening the top panel of the machine.
• 1 Phase or 3 Phase connections.
• 208-240 volts, 60 Hz.
• 3 wire plus ground.
• Suggested Minimum
Wire Size -- 12 Ga.
Always disconnect electrical power to the machine before performing any adjustments or service.
Liquid Chemical Connection
In the left rear corner of the washer is the chemical injection assembly. This is where all chemical hose connections are made. The chemical hoses should be inserted into the round pvc pipe a minimum of 14” and a maximum of 18” to eliminate chemical buildup in the pipe and/or restrict water flow to the tub.
Fusing Requirements:
Dual element time delay fuse or equivalent breaker of amperage specified below.
 1 Phase or 3 Phase 15 amp
WCVD-18-12,WCVD-25,WCVD-40
1 Phase or 3 Phase 20 amp
WCVD-55, WCVD-75
1 Phase 20 amp
WCVD-18-10 120 volt
Rotation in extract as viewed through glass door at front of washer models WCVD-25,WCVD-40,WCVD-55,WCVD-75 will be counter- clockwise. Rotation in extract as viewed through glass door at front of washer model WCVD-18 will be clockwise.
