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.
Page 26
Liquid Chemical Connection In the left rear corner of the washer is the chemical injection as- sembly. 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.

Control Mounting Trough Remove top panel to access control trough. (see Removing Top Panel) It sets on the right side of the machine and holds the control PCB’s, transformers,and pressure switch. Main Data Communication Cable Goes between front PCB board and Variable Frequency Drive unit mounted center rear of machine. It has telephone type connectors at each end and is inserted at Controller PCB and the Variable Frequency Drive.
Pressure Switch Caution (Not recommended by Factory!) Changing Factory preset adjustment voids all factory water usage specifications. The pressure switch sets the water level in the washer. As the water level rises, it compresses the air in the pressure switch hose. When the washer reaches the desired water level, the compressed air in the pressure switch hose opens the contacts in the switch, shutting off the water.
Page 62
Pressure Sensor Electronic The Electronic Pressure Sensor comes standard on all models Starting Septembet, 1st 2015. Machines Level Chart manufactured before this date can be upgraded with Kit 9732-213-001. The Pressure sensor is adjustable. The Factory settings chart will let you know the starting values for each machine and by following the Switch position chart you can adjust the water levels in 1/4 inch increments from that starting value.
Power Connection Terminal Block This terminal block sets at the very back of the control trough. Incoming power to the washer should connect here. (see Electrical under Installation and Operation Section for exact connections) Rear Delta Variable Frequency Drive: Main power is connected to terminals L1, L2, and L3 on the Delta drive. If the washer is connected to a three phase source, there should be voltage present on all three terminals.
Page 65
MAXIMUM SPIN SPEED ADJUSTMENT: If desired, the washer can be adjusted to limit the maximum extract spin speed for all wash cycles. To make this adjustment, a jumper wire must either be installed or removed on the Variable Frequency Drive (VFD), depending on the washer model and desired speed.
Electrical Path Circuit Schematics Start Circuit Power travels into the machine on L1 & L2 & (L3) ( if 3 phase used). 208- 240VAC goes to a Control Transformer ( must be checked at start -up to coincide with machine operating voltage) that steps the voltage down to 115VAC for the controls.
Wash Circuit As the washer fills the tub through the back of the machine with either one or both the C1 Cold and H1 Hot Water Valves, the Wash Basket will tumble one direction for 12 seconds, pause, and then reverse di- rection for 12 seconds.
