6.0 Maintaining & Servicing the System
Main dispenser power must be disconnected prior to maintaining or servicing the unit. Power switch must be set to “off” and
power cord must be removed from wall power socket.
Always wear appropriate Personal Protective Equipment (PPE), including eye/face protection, gloves, and aprons, when
replacing chemicals or coming in contact with any liquid in the system.
Do not plug or unplug RS-485 cables when power is applied to the system. Do not apply power to the system until all
modules are properly addressed and all RS-485 cables and plugs (dongles) are properly connected to the modules.
