F-801 Internal RO System by GE Osmonics

1.8Monitors and Controls

RO Power Switch:

The RO Power Switch is mounted on the back of the remote monitor module. The switch is used to turn the F-801 RO unit on and off.

Inlet Water Sensor:

Monitors the quality of the inlet water. Inlet quality is compared to the outlet (product) water quality and is displayed as "percent rejection" on the front panel.

Product Water Sensor:

The Product Water Sensor is used in conjunction with the inlet water sensor by the percent-rejection circuitry to calculate the membrane rejection rate. The rate of rejection is displayed from 70% - 99% in a 5 LED array on the front panel.

Total Dissolved Solids (TDS) Sensor:

Samples the product water quality via the sensor probe, and the final quality of the product water is indicated on a digital display on the front panel as TDS in mg/L and ppm. The monitor is temperature compensated to adjust the display value to changing water temperature.

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.

Pre and Post filter Pressure Gauges:

The Pre-filter pressure gauges are mounted on top of the pre-filter housing and display the feed water pressure from zero to 100 PSI. The two gauges are used to determine the feed water pressure and when compared against each other to determine fouling of the filter (delta pressure).

Product Pressure Gauge:

The Product Pressure Gauge reads the product pressure from 0 to 100 PSI and is located on the RO module right side panel. Product pressure will read zero (or close to) 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. The Fresenius dialysis machine requires a minimum inlet pressure of 20 PSI.

Pump Pressure Gauge:

The Pump Pressure Gauge reads the pump pressure from 0 to 300 PSI and is located on the RO module right side panel. It is used for monitoring during operation and when adjusting the pump pressure, and is located on the front of the RO.
