Product Overview
Description Description
This returns a portion of the pumped concentrate in the supply line back to the pump inlet when the desired concentrate
output requires the pump to operate at an RPM that is lower than possible by the pump. The components in this subsystem
include:
• Node controller—this connects to the low-flow control valve, flowmeters.
• Low-flow valve—this controls the concentrate return flow.
• Magnetic flowmeter—this measures the flow of concentrate.
• Split CANbus 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.
• Split CANbus cable—this connects the node controllers to one another and the control box.
• Concentrate control valve—this controls the concentrate flow.
• Magnetic flowmeter—this measures the concentrate flow.
• Check valve—this prevents reverse 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.
• Split CANbus cable—this connects the node controllers to one another and the control box.
• Prime bypass line—this is an installer-supplied valve that prevents contaminating the concentrate during training. When
water is substituted for concentrate during training or testing, and you have concentrate in the supply tank, this bypass
valve prevents water from contaminating the concentrate supply. Note: You must drain any remaining water in the line
before priming the system with concentrate to prevent contamination.
