Installation

On U4 and earlier model units, a stainless steel box at the right rear of the control module houses a terminal strip which furnishes supply output signals for the chemical injection supply pumps. Refer to Figure 19 for an example of a typical terminal strip decal.

On U5 and later model units, the terminal strip that furnishes the supply output signal for the chemicals injection and supply is located inside the control module at the rear. Access is through the rear panel of the module.

Terminals Supply 1 through Supply 5 provide

120 VAC or 240 VAC fused at 500 mA. (Refer to the decal at the external supply terminal strip to determine whether the washer-extractor provides 120 VAC or 240 VAC, as well as other pertinent information.) These terminals may be used to provide signals to the chemical injection supply system but must not be used to provide power to the actual pump. Do not attempt to increase fuse rating as this may cause damage to the washer-extractor’s circuitry.

Any injection system pump which requires110 VAC must be powered by a separate external power source.

CAUTION

Attempting to obtain 110VAC by using L1 or L2 with the common may damage laundry machine circuitry and/or the chemical injection system. Using a 240VAC power wire in the washer- extractor and an earth ground to obtain 110VAC could cause microprocessor problems.

Consult the chemical injection supply system instructions for operational details.

Control Function Test

The washer-extractor should be cleaned after the installation is complete. A function test should then be executed on the unloaded machine:

1.Check the power supply for such characteristics as correct voltage, phase, and cycles to be certain they are correct for the washer-extractor.

2.Open manual shut-off valves to the washer- extractor.

NOTE: If the washer-extractor is equipped with the WE-6 microcomputer, press the emergency stop button at this point in the procedure.

3. Apply power to the washer-extractor.
