Water Saver
Taken from the 1959 "Use and Care" book:
"Small loads (up to 5 pounds of clothes with no one piece larger than a man's shirt) can be laundered using the water saver feature. Follow the general procedure for laundering according to the model being used with the following exceptions.
1. The detergent must be placed in the washer and allowed to dissolve before adding the clothes.
2. When detergent is dissolved, for personal safety push control to "OFF" position and be sure that all parts of washer have stopped moving, then add clothes. Replace Filter Pan.
3. Pull out control knob and machine will continue to fill with water. When the desired amount has entered, press the WATER SAVER Control momentarily - then release. Be sure the level of the water in the washer is not below the ridge on the Activator, regardless of how small the load. After the washing portion of the cycle is complete, the washer resets automatically for a full tub of water. If a partial fill is desired for rinsing, return to the machine while it is filling for the rinse portion of the cycle. When desired amount of water has entered, press the WATER SAVER Control.
WHEN LESS THAN A FULL WASHBASKET OF WATER IS USED, RECIRCULATED WATER DOES NOT ENTER THE FILTER PAN."
