(For models with “LSD” option only)
Liquid soap viscosity is measured in “cps” (centipoise). The liquid soap chosen to be used with
Willoughby’s Liquid Soap Dispenser should be between 100cp and 2500cp.
The viscosity of the soap should be thin and free flowing.
Some soap types are available in a concentrate and must be diluted with water.
The pH (acidity) level should be in the range of 6.5 to 8.5.
Soap which is too acidic (pH less than 6.5) can corrode stainless steel and degrade rubber, plastic,
or chrome-plated materials.
Soap that is outside the range of 6.5 - 8.5 might be harsh on the hands or skin.
(Generally, any quality soap meeting the viscosity and pH guidelines should work well.)
Recommended Maintenance Schedule
To maintain proper function, Willoughby’s Liquid Soap Dispenser should be cleaned periodically
to remove soap residue. The Liquid Soap Spout should be soaked in hot water for a period of 30
minutes when cleaning is being performed. The soap tray should also be cleaned with hot water.
