1 2.0 INST ALL A TION 2.1 Mounting the Unit When installing your new GE Infrastructure Wat er & Process Technologies reverse osmosis (RO) machine, allow at least 45-inches (114 cm) above the machine for mem- brane element removal and loading.
2.3 Install ing Clean-In-Place V alves NO TE: Clean-In-Place (CIP) valves are not included with the machine. The CIP valves must be purchased and installed by the customer. When installing the CIP valves, a three-way valve should be installed in the inlet feed stream of the machine.
Table 2.2 E-Series Feed Water Requirements * American Standard for Testing Materials 2.6 Transporting Pure W at er (P ermeat e) to P oint-of -Use The pure water , or permeat e, is in an aggressive sta.
2.7 Pressure Correction F actors It is often necessary t o operate RO machines with permeat e back pressure. Permeate back pressure will decrease permeate production. See Table 2.3 (Pressure Correction Factors) to calculat e loss of permeate. Table 2.
2.8 Electrical This RO machine requires two supply voltages; the control voltage and the pump motor voltage. 2.8.1 Single-Phase Electrical The control voltage can be connected t o either a 115 V AC, 60 Hertz or 220 V A C, 50 Hertz single-phase power supply.

7 and complies with local and national electrical codes, move ont o Section 2.10 (Pretreatment for Water Purif ication). NO TE: External control contacts are normally closed, dry contacts.
6. Turn the ON/OFF button on the machine ON. Syst em will open allowing water to flow through the machine to the drain through the permeat e and concen- trate CIP valves. Let the machine run to drain for 5 - 10 minut es. This provides a wet start-up of the pump and removes any air in the system.
The concentrate valve is drilled, and when completely closed the machine is running at the correct concentrate flow for a 75% recovery (Table 2.4, Flow Specif ications for E4-Series Machines). If the temperature of the inlet feed water is not 77°F (25°C) use the Temperature Correction Factor Table (Technote 113).
2.14 Recovery The machine flow specif ications list ed below are based on 25 ° C (77 ° F). Table 2.4 Flow Specif ications for E4-Series Machines 10 2200 50-75% LPM/GPM 5.8/11.6 5.8/11.6 1.9/0.5 11.5/3.0 7.7/2.0 4400 50-75% LPM/GPM 11.6/3.06 11.6/3.06 3.
11 2.15 Aut oflush Timer 2.15.1 Programming the Autoflush Timer The Autoflush timer clock operat es and displays in real time, but the Autoflush feature will only work when the RO machine is operating. When the machine is operating in the Autoflush Mode, the total flow through the machine is increased.
STEPS 1. While holding down the Clock Key ( ⊗ ), press the h key to advance to the current minute. 2. While holding down the Clock Key ( ⊗ ), press the h key to advance to the current minute. 3. While holding down the Clock Key ( ⊗ ), press the h key to advance to the current minute.
2.15.4 Programming Twenty-Four Hour or Seven Day Schedules NO TE: It is helpful to write out the program schedules before programming the time. Example: Figure 2.3 Programming the Timer 2.15.5 Changing a Program Select the program to be changed with the Prog.
2.15.7 Troubleshooting the Autoflush Timer 14 PROBLEM: Days are flashing, pressing any Key does nothing except “Hand” Key turns output ON and OFF . SOLUTION: Time of Day and Day of Week have not been set . See Section 2.15.3 (Setting-Up the Autoflush Timer Clock).
2.16 Cal ibrating the Conductivity Probe STEPS 1. Make sure the calibration met er is in Measure Mode (with the ME AS LED light ON). 2. Immerse the Conductivity Probe in a 13.00 microSiemens (mS) prepared solu- tion. 3. Immerse and agitate Conductivity Probe, and wait for the reading t o stabilize.
2.17 Operation and Maintenance The operation and maintenance of an E-Series RO machine requires regular data recording and routine preventative maint enance. It cannot be emphasized enough the importance of f illing out the Daily Log Sheet (Technot e 106) during each operat- ing shift .
2.18 Pre-f ilt er Cartridge A 5 micron pre-f ilter cartridge is fact ory installed to protect the membrane elements and valves from particles, which may be in the feed water. To order replacements, see the Spare Parts List (Technote 118, P/N 1233377).
When set properly, the RO machine, the CIP pump, and the CIP con- tainer should be assembled in a loop conf iguration to recirculat e the water through the machine and back to the container during clean- ing. The size of the CIP container should be a minimum of three times the permeate rat e.
5. Let the CIP solution dwell in the machine for 20 minutes. 6. After the 20 minut e dwell time, start the CIP recirculation process again for 10 minutes. 7. After the 10 minut e recirculation time is complete, de-energize the machine. Then, open the inlet water l ine and route the concentrat e and permeate l ines to the drain.
20 NO TE: As previously mentioned, the manufacturer recommends use of a CIP or booster pump t o circulate the cleaning solution during membrane element cleaning. 7. After suction cleaning cycle is complet e, reopen inlet water and flush machine to drain for twenty minut es.
21 5. Reattach the housing clamp and tighten. 6. Next reconnect the permeate and concentrat e lines. The machine is ready for start-up..
2.22 Troubleshooting This troubleshooting guide can assist you in identifying common operating problems you may experience with your machine. Many of these problems can be easily corrected by the operator , however , for those that persist or are not understood, you should contact the GE Customer Support Cent er.
