14693e – 31 Mar 03 1 - 9 General Information
1.8 Monitors and Controls
Inlet Water Valve Switch:
The Inlet Water Valve Switch is mounted on the control panel. The switch is used
to energize a solenoid, pressurizing the system with feed water.
RO Pump Power Switch:
The RO Pump Power Switch is mounted on the control panel. The switch is used to
energize the RO pump/motor. The inlet water switch must be ON for the
pump/motor to operate.
Disinfect Switch:
The Disinfect Switch is mounted on the front panel. This switch is used to
introduce disinfectant or cleaning agents into the RO through the disinfect port.
Pressure Adjust Regulator:
The Pressure Adjust Regulator inside the RO is used to set the maximum product
pressure needed to supply a dialysis machine. Adjusting this regulator will also
result in small adjustments in the pump pressure.
Product Pressure Gauge:
The Product Pressure Gauge reads the product pressure from 0 to 100 PSI. Product
pressure will read zero when the product line is not connected to a dialysis unit and
the product hose is connected to the product fitting and the valve is open.
Pump Pressure Gauge:
The Pump Pressure Gauge reads the pump pressure from 0 to 300 PSI. It is used
for monitoring during operation and when adjusting the pump pressure, and is
located on the front of the RO.
Operate/Flush Valve:
The Operate/Flush Valve is a 1/4-turn ball valve. When in the operate mode, the
valve is in the closed position. When the valve is turned at any point towards flush,
the valve is open. The closer to the flush point, the more the valve is open. When in
flush, the valve bypasses the waste flow tube.
Disinfect Port:
The Disinfect Port is a quick-disconnection port for the introduction of disinfectant
or cleaning agents. The port has a check valve that closes when there is no hose
connected to the fitting.
Feed Port:
The Feed Port is a quick-disconnection port for the introduction of feed water to the
RO. The port has a check valve that closes when there is no hose connected to the
fitting.
