Z Series RO System by GE Osmonics USE PROPER POWER CONNECTIONS: Use proper wiring and connection methods to satisfy hospital electrical codes. DEVICE LABELING: Do not under any circumstances; remove any Caution, Warning or any other descriptive labels from the devices until the conditions warranting the label are eliminated. DO NOT OPERATE IN A FLAMMABLE ATMOSPHERE: To avoid fire or explosion, do not operate this device in an explosive

Z Series RO System by GE Osmonics WATER: Reverse osmosis systems require a reliable water source. Additionally, it is necessary to have adequate flow rates and pressure. The Z-Series RO is equipped with safety devices to shut down the unit when the pressure falls below 10 PSI. If flow rates drop below the required level the pressure will drop as well, causing the RO to shut down. It is important to run water at the design flow rate whe

Z Series RO System by GE Osmonics 1.6 Theory of Operation The Z-Series RO is an open-frame mounted reverse osmosis unit which is fully monitored for pressure, percent rejection and output TDS. The unit includes pre- filtration to remove gross particles capable of fouling membranes and damaging the high- pressure pump. The RO pump provides the pressure required to drive water through the membranes at economical flow rates and improves the me

Z Series RO System by GE Osmonics Inlet Water Sensor: The Inlet Water Sensor monitors the quality of the feed water. Input water quality is compared to the output (product) water and is displayed as "percent rejection" on the front panel. Disinfect Inlet Valve: The Disinfect Inlet Valve is a 1/4 turn ball valve which connects to the input water side of the pump. The valve is used whenever cleaners or disinfectants are introduced to the

Z Series RO System by GE Osmonics Waste Recirculation Flow Meter: The Waste Recirculation Flow meter displays the amount of recycled waste water returned to the inlet of the high-pressure pump. The flow is displayed in a panel mounted flow meter. Automatic Flush: The Automatic Flush feature is intended to reduce the concentrations of suspended solids at the RO membrane surface, thereby reducing the accumulation of scale. This is accomp

Z Series RO System by GE Osmonics Inlet Solenoid Valve: The Inlet Solenoid Valve is located on the riser pipe of the Z Series RO and serves to shut off the water supply to the RO system. It is actuated open when the power switch is placed in the ON position. Inlet Water Valve: The Inlet Water Valve is located after the inlet manifold and before the pre-filter. The valve allows manual shut off of the water supply to the unit. This valve

Z Series RO System by GE Osmonics Percent Rejection Display: The Percent Rejection Display is a 5 LED panel mounted array that indicates how the RO membranes are performing. The lights correspond to 99%, 95%, 90%, 85%, and >70% rejection. The 99% light, when illuminated, indicates a need to evaluate the RO system performance. CAUTION: RO units do not normally perform in excess of 99%; verify this reading with an independent meter and

Z Series RO System by GE Osmonics RO Interlock: The RO Interlock circuit, when activated, will not allow the RO unit to operate (run). An electric signal is sent from the RO unit control box (panel) to a normally open micro switch on the device. These devices are typically part of the pretreatment system. When the micro switch is closed, the signal returns to the RO unit control box activating the RO interlock circuit thus disabling RO op

Z Series RO System by GE Osmonics Product Divert System: The divert valve rotates open directing water to drain during RO system start-up and/or a high TDS alarm condition. The opening of the divert valve is communicated with the illumination of an indicator on the product divert controller. The open divert valve directs product water to drain and will remain open as long as an alarm condition exists and close after an approximate two-minut

Z Series RO System by GE Osmonics Disinfect Alarm Monitor (DAM) The Disinfect Alarm Monitor reduces the possibility of patient and equipment exposure to disinfectants. The monitor provides a dependence requiring that Disinfect key switches, located on the RO Controller and RO Status Monitor, are purposely engaged prior to introducing disinfectants or cleaning agents into the loop piping. The key switch dependency ensures that disinfect ope

Z Series RO System by GE Osmonics Ultra Filters and Sub-micron Filters Ultra and Sub-micron filters are used to remove undesirable solids from the water. Normally these filters are used in the distribution loop to remove microorganisms and media fines. In some instances ultra filters are used in front of RO units to remove harmful colloids. In these circumstances the ultra filter is employed in a unit similar to an RO. Most frequently,
