8 Transfer line
9 Priming line
Product Overview
Description Description
This optional line balances the concentrate supply lines when the flow is lower then the minimum concentrate pump flow
specification—30 gpm (114 L/min). The components in this subsystem include:
• Node controller—this connects to the low-flow control valve, flowmeters.
• Low-flow circulation valve—this controls the flow of concentrate.
• Magnetic flowmeter—this measures the flow of concentrate.
• CANbus splitter and cable—this connects the node controllers to one another.
This allows you to transfer or relay concentrate from the apparatus to another location. The components in this subsystem
include:
• Node controller—this connects to and controls the concentrate control valve, flowmeters.
• CANbus splitter and cable—this passes CANbus bus commands to the next node controller in the chain.
• Concentrate control valve—this controls the concentrate flow.
• Magnetic flowmeter—this measures the concentrate flow.
• Check valve—this prevents improper fluid flow in the line.
This evacuates air from the concentrate pump inlet as the system primes before operation. The components in this
subsystem include:
• Priming valve—this opens to allow air to evacuate the line before operation.
• CANbus splitter and cable—this connects to the valve to control its operation.
