Operation
The shaft seal assembly includes a collar held in place on the cylinder shaft with setscrews. The collar has a flange with a ceramic ring which makes contact with a spring-loaded face seal enclosed in a housing. The collar contains two internal O-rings which maintain contact with the cylinder shaft.
The polypropylene supply dispenser is mounted on the right side of the washer-extractor, viewed from the front. The dispenser has five supply compartments, numbered 1–5, starting from the rear of the machine. The compartments hold plastic supply cups that are used for either liquid or dry supplies. A nozzle flushes supplies from the cups with water for the time programmed in the cycle.
Liquid supplies can be injected directly into the cups by a customer-supplied external chemical supply system. Five hose strain reliefs on top of the supply dispenser facilitate connection to an external supply system. A terminal strip inside a compartment attached to the left side of the control module, viewed from the rear of the washer-extractor, provides connection points for external supply signals.
Emergency Stop ButtonA red emergency stop button is located on the control panel. Push the button in to stop the washer-extractor in emergency situations. Turn button to the right and pull out to reset.
Drain StepsModels that display WE-6 Firmware ID Code “ARWCO1” and later or “HRWC18” and later (i.e. “HRWC19”) after power up have two additional drain steps called “WASH DRAIN” and “Drain 5.” The steps provide a potential reduction in total cycle time because steps are shorter.
“WASH DRAIN” is used for draining to the sewer (“main” drain [drain 1]) when a spin step does not follow a “WASH DRAIN.” Any other steps (for example, fill step) may be programmed after a “WASH DRAIN” step.
“DRAIN 5” is identical to a “DRAIN 1” step, except it does not attempt to rebalance the load. “DRAIN 5” is recommended before a medium spin, a lower speed spin or a spray rinse step. Refer to Programming manual for additional details.
LED DisplayThe WE-6 control has a six-digit LED display. References to display indications pertain to the first four digits of the display reading left to right. The last two digits on the right side of the display will indicate either the last cycle used or the current cycle in progress. Refer to Figure 5.
