2.0 INSTALLATION 2.1 Mounting the Unit When installing your new GE Osmonics reverse osmosis (RO) machine, allow at least 45-inches (114.3 cm) above the machine for membrane element removal and loading. If space is not available, the entire membrane element housing can be removed for membrane element change-outs. If the membrane element housings are to be removed to change-out the membrane elements, at least 25-inches (65.3 cm) is required at one end of each membrane element housing and 6-inches (15.
2.4 Feed Water Requirements The following feed water requirements must be met before installing your E2/EZ2-Series machine to ensure quality permeate and extended membrane element life. Refer to Table 2.2 (E2/EZ2-Series Feed Water Requirements) for feed water information. Table 2.2 E2/EZ2-Series Feed Water Requirements Temperature Typical: 50° - 85°F (10° - 29°C) Limits: 33° - 104°F (0.60° - 40°C) Inlet Pressure Minimum: Maximum: Chlorine (continuous feed) Operating pH Silt Density Index (SDI) * 2.
2.6 Machine Control 2.6.1 Economy Model To remotely control the Economy Model (ECN) with float switches and/or pretreatment lockout, remove the jumper between terminals 4 and 5 and wire in the float switches or pretreatment components in series. After all field wiring is complete and complies with local and national electrical codes, move onto Section 2.7 (Single-Phase Electrical). NOTE: 2.6.2 External control contacts are normally closed, dry contacts.
Your RO is designed to operate on softened tap feed water with an SDI of 5 or less. The pH should be in a range of 5.5 - 8.5. Exposure to any levels of chlorine may cause irreversible damage to the Thin-layer composite (TLC) polyamide (PA) membrane elements in your machine. Daily water checks are recommended to ensure the integrity of your pretreatment and RO system. Refer to Table 2.2 (E2/EZ2-Series Feed Water Requirements). 2.8.
6. Turn the ON/OFF button on the machine ON. 7. As the pump starts to build pressure, begin to adjust the valves in the following manner: start by slowly closing the concentrate valves while slowly opening the recycle valve (Figure 2.1, Flow Control Center). CAUTION: 8. Monitor machine to ensure inlet pressure of 30 - 60 psi (2.1 - 4.1 bar) is maintained during operation.
9. Complete the Start-Up Data Sheet (Technote 101). The Start-Up Data Sheet and the Daily Log Sheet (Technote 106) are invaluable in diagnosing the performance of the equipment, and must be be kept for reference. If you have questions concerning the operation of your machine or the method of data recording, contact your distributor or the manufacturer.

2.11 Permeate Back Pressure Correction Factors It is often necessary to operate RO machines with permeate back pressure. Permeate back pressure will decrease permeate production. See Table 2.5 (Permeate Back Pressure Correction Factors) to calculate loss of permeate. Table 2.5 E2/EZ2-Series Permeate Back Pressure Correction Factors BACK PRESSURE % LOSS OF PERMEATE FLOW PRESSURE CORRECTION FACTOR (PCF) 10 psig (0.7 barg) 5% 0.95 20 psig (1.4 barg) 10% 0.90 30 psig (2.0 barg) 15% 0.
2.12 Operation and Maintenance The operation and maintenance of an E2/EZ2-Series RO machine requires regular data recording and routine preventative maintenance. It cannot be emphasized enough the importance of filling out the Daily Log Sheet (Technote 106) during each operating shift. A Start-Up Data Sheet (Technote 101) should have been completed at start-up. The StartUp Data Sheet contains pertinent facts on the operation of your machine.
2. Allow the machine to operate with the concentrate valve open 1/2 - 3/4- of a turn (Step 1) for 10 - 15 minutes. 3. After 10 - 15 minutes, return the concentrate valve to its previous setting, and return to normal operation. CAUTION: 2.15 When opening the concentrate valve, never allow the machine’s primary pressure to drop more than 10% below normal operating pressure (Table 2.3, E2/EZ2-Series Primary Pressure Range).
Figure 2.2 E2/EZ2-Series Closed Loop Membrane Element Cleaning NOTE: This clean container will be referred to as the Clean-In-Place (CIP) container. 4. Disconnect and route the inlet, permeate, concentrate lines from their service locations to the CIP container (Figure 2.2 E2/EZ2-Series Closed Loop Membrane Element Cleaning. 5. Connect the CIP feed line to the E2/EZ2-Series machine inlet feed water port (Figure 2.2, E2/EZ2-Series Closed Loop Membrane Element Cleaning). 6.
8. After circulaiting the macine for 10 - 15 minutes or solution has reached 95°F (35°C), shut machine OFF. 9. Dump solution. Repeat Setps 6 - 8. 10. With machine OFF (Step 8), let cleaning solution dwell in machine for 15 - 30 minutes. 11. After 15 - 30 minutes, reconnect feed to RO unit and connect concentrate and permeate to drain. Turn machine ON and flush permeate water to the drain for 10 - 15 minutes. This ensures that all cleaning agents have been removed for the machine. 12.
element housing. As you reach the bottom of the housing slowly guide the PVC stem or stinger on the end of the membrane element into the head of the end cap. As the membrane element slides into the housing the brine seal will be on the top (Figure 2.4, Direction of Membrane Element Installation). Figure 2.3 Membrane Element Installation 3. Next, load the up flow membrane elements, by lubricating all brine seals, O-rings, and the membrane element stingers.

2.17 Troubleshooting This troubleshooting guide can assist you in identifying common operating problems you may experience with your machine. The operator can easily correct may of these problems, however, for those that persist or are not understood you should contact the GE Customer Support Center. Have the following information available when calling the Customer Support Center: 1. Machine installation date 2. Model number 3. Serial number 4. Detailed description of problem.
TROUBLESHOOTING GUIDE PROBLEM Low operating pressure (continued) Low permeate production . POSSIBLE CAUSES REMEDIES Concentrate or recycle valve to Refer to Section 2.9 for properfar open ly setting concentrate and recycle valves Low operating pressure See above. Machine operating on cold water Check the water temperature. If needed, install a hot/cold tempering valve. Permeate production rate is dependent on 77°F (25°C). Refer to Section 2.5 (Temperature Correction Factor).
TROUBLESHOOTING GUIDE PROBLEM POSSIBLE CAUSES Low permeate production (continued) Useful life of membrane element(s) expired Install new membrane element(s). See Spare Parts List (Section 2.20). Inaccurate permeate flow meter (DLX only) Check the flow rate manually with a stop watch and a calibrated container. Low concentrate flow with normal or high operating pressure Dirty or fouled membrane element (s) Flush and/or clean machine.
TROUBLESHOOTING GUIDE PROBLEM POSSIBLE CAUSES ON/OFF switch ON: machine not running (continued) Pressurized storage switch or storage tank float switch cut power to machine The storage tank may be full. The switch control may require adjustment. Thermal overload of motor Allow the machine to cool. Check the Amp draw to the machine. Pump motor failure Check the fuses or circuit breakers; measure the voltage. Contact your distributor for service.
TROUBLESHOOTING GUIDE PROBLEM Flow through machine while power is OFF POSSIBLE CAUSES REMEDIES Inlet solenoid valve not fully Ensure valve is not getting any closed power when machine is OFF. Replace inlet solenoid valve.
