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-inch

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: 30 psig (2.1 barg) Maximum: 60 psig (4.1 barg) Chlorine 0 parts per millio

2.6 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). NOTE: External control contacts are normally closed, dry contacts. 2.6.2 Deluxe Model To remotely control the

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. Daily water checks are recommend- ed to ensure the integrity of your pretreatment and RO system. Refer to Table 2.2 (E2/EZ2-Series Feed Water Requirements). 2.8.2 Machine Start-Up Preparation Check the function and int

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: Monitor machine to ensure inlet pressure of 30 - 60 psi (2.1 - 4.1 bar) is maintained during operation. 8. After 20 - 30 minutes of flushing permeate to the drain, ensure all chemical residue has been removed before hooking up to po

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 con- cerning 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.

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 Start- Up Data Sheet contains pertinent facts on the operation of your machine. These two records are invaluable in diagnosing th

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: 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). 2.15 Membrane Element Cleaning Periodic cleaning of the machine with appropriate

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 per- meate 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. If clea

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. With the up flow membrane element and
