1 2.0 INST ALLA TION 2.1 Mounting the Unit When installing your new GE Osmonics reverse osmosis (RO) machine, allow at least 45-inches (1 14.3 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 housing[...]

2.4 Feed W ater 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 T able 2.2 ( E2/EZ2- Series Feed W ater Requirements) for feed water information. T able 2.2 E2/EZ2-Series Feed W ater Requirements * American Standard fo[...]

Y our 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 (P A) membrane elements in your machine. Daily water checks are recommend- ed to ensure the integrity of your pr[...]

6. T urn 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 maint[...]

9. Complete the Start-Up Data Sheet (T echnote 101). The Start-Up Data Sheet and the Daily Log Sheet (T echnote 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 manuf[...]

2.1 1 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 T able 2.5 (Permeate Back Pressure Correction Factors) to calculate loss of permeate. T able 2.5 E2/EZ2-Series Permeate Back Pressur e Correction Factors W ARNING : I[...]

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 (T echnote 106) during each operating shift. A Start-Up Data Sheet (T echnote 101) should have been complet[...]

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 nor[...]

2.17 T roubleshooting 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[...]

16 REMEDIES Refer to Section 2.9 for proper- ly setting concentrate and recycle valves See above. 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 (T emperature Correction Factor). Refer to Section 2.18 for cor- rect membrane element installation[...]

17 REMEDIES Install new membrane ele- ment(s). See Spare Parts List (Section 2.20). Check the flow rate manually with a stop watch and a cali- brated container . Flush and/or clean machine. Replace the O-rings, check the sealing surfaces on the O-ring groove and end caps. Replace damaged parts. Replace with new membrane elements. See Spare Parts Li[...]

18 REMEDIES The storage tank may be full. The switch control may require adjustment. Allow the machine to cool. Check the Amp draw to the machine.
