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.
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.
2.6 Machine Control 2.6.1 Economy Model T o 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.
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.
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).
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.

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.
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.
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.
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.
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. W ith machine OFF (Step 8), let cleaning solution dwell in machine for 15 - 30 minutes. 1 1. After 15 - 30 minutes, reconnect feed to RO unit and connect concentrate and per- meate to drain.
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).

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 .
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).
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.
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. Check the fuses or circuit breakers; measure the volt- age. Contact your distributor for service. Disconnect and clean the concentrate valve.
19 REMEDIES Ensure valve is not getting any power when machine is OFF . Replace inlet solenoid valve. POSSIBLE CAUSES Inlet solenoid valve not fully closed PROBLEM Flow through machine while power is .
