TB-106 Cleaning and Maintenance For Bobrick B-850,
B-852, B-855, B-856 or B-858 Automatic
Counter-Mounted Soap Dispensers
Quality soap dispensers require good quality soap and periodic maintenance to properly operate. For reliable
long-term use, perform regular maintenance for each unit. Most soap dispenser problems are caused by soap
that is too thick or corrosive, or by a lack of maintenance. If proper soap is being used, problems can still
arise if dispensers have never been cleaned. Bobrick recommends a viscosity of 100 to19,000cP. With proper
maintenance and soap, Bobrick dispensers will provide long term, trouble free operation.
Deactivate the soap dispenser by placing your finger over the Fiber Optic Sensor area while you clean. The
sensor is located just behind the Nozzle Tip. Once dispenser is cleaned, remove finger from the sensor area. Or
un-plug the Power Supply located on the bottom of the housing (LED will not light).
Daily cleaning:
• Using a soft, dry cloth wipe the exterior.
• If dispenser is really dirty gently wipe the dispenser with a cloth moistened with warm water and a
diluted neutral detergent. Remove the detergent with a soft damp cloth and then rub with a second soft,
dry cloth.
Periodic cleaning (3 to 6 months)
• Remove Nozzle Tip and run under warm water.
• To remove Nozzle Tip for cleaning, cover the Sensor area with your finger to prevent dispensing of soap.
Turn Nozzle to the left to loosen. Rinse Nozzle under hot water to loosen any soap residue and replace.
Turn Nozzle to the right to tighten
DO NOT use abrasive or chemical cleaners (including chlorine bleach) to clean Spout, as it may dull the luster and attack the
chrome-plated exterior. Use ONLY mild soap and water, then wipe dry with clean cloth. While cleaning the bathroom counter top,
protect the Spout from any splattering of cleaner. Acids and cleaning fluids will discolor or remove chrome plating.
