THEORY OF OPERATION-CONTINUED
Automatic Soap Dispenser
An automatic soap dispenser is fitted which dispenses dissolved solid laundry detergent, bleach, and
laundry sour in preset amounts on demand to each washer. Hot water from the boiler is fed into the
automatic soap dispenser, regulated, and delivered as required by washer-controlled solenoid valves to
the appropriate laundry chemical canister. Laundry chemicals in solution are collected in a common
sump and fed to a pump, which then delivers the dissolved chemicals to the washers.
