INSTALLATION 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. -
Page 6: Feed Water Requirements
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 E2/EZ2- Table 2.2 ( Series Feed Water Requirements) for feed water information. Temperature Inlet Pressure Chlorine (continuous feed) -

Machine Control 2.6.1 Economy Model To remotely control the Economy Model (ECN) with float switches and/or pre- treatment 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 com- plete and complies with local and national electrical codes, move onto Section 2.7 (Single-Phase Electrical). -
Page 8: Machine Start-Up Preparation
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 chlo- rine may cause irreversible damage to the Thin-layer composite (TLC) polyamide (PA) membrane elements in your machine. -

Turn the ON/OFF button on the machine ON. 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: Monitor machine to ensure inlet pressure of 30 - 60 psi (2.1 - 4.1 bar) is maintained during operation. -

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 con- cerning the operation of your machine or the method of data recording, contact your distributor or the manufacturer. -

Page 12: Permeate Back Pressure Correction Factors
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. BACK PRESSURE 10 psig (0.7 barg) 20 psig (1.4 barg) 30 psig (2.0 barg) -
Page 13: Operation And Maintenance
A pressure drop across the filter of 8 psi (0.55 bar) or more during operation indicates that the pre-filter cartridge(s) need changeing. Use only GE approved filters rated at 2 microns or less. Refer to Technote 109 (Spare Parts List) for pre-filter cartridge replacements. Do not attempt to clean used pre-filter cartridges. -

The permeate quality begins to decline. The reading on the final pressure gauge begins to change noticeably. GE recommends that you clean your E2/EZ2-Series RO machine every quarter. You may have to clean the RO machine more frequently, depending on the quality of your feed water. -

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. 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. -

After circulaiting the macine for 10 - 15 minutes or solution has reached 95°F (35°C), shut machine OFF. Dump solution. Repeat Setps 6 - 8. With machine OFF (Step 8), let cleaning solution dwell in machine for 15 - 30 minutes. After 15 - 30 minutes, reconnect feed to RO unit and connect concentrate and per- meate to drain. -
