2.0 INSTALLATION 2.1 Mounting the Unit When installing your new GE Infrastructure Water & Process Technologies reverse osmosis (RO) machine, allow at least 45-inches (114 cm) above the machine for mem- brane element removal and loading. If space is not available, the entire membrane element housing can be removed for membrane element change outs. If the mem- brane element housings are to be removed to change out the membrane elements, at least 6-inches (15.2 cm) is required at the end of each

2.3 Installing Clean-In-Place Valves NOTE: 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. The tees on the permeate and concentrate lines should be installed with two-way valves. All valves should be installed in a manner that will allow circulation of the cleaning chemicals through the machine and back to

2.7 Pressure Correction Factors It is often necessary to operate RO machines with permeate back pressure. Permeate back pressure will decrease permeate production. See Table 2.3 (Pressure Correction Factors) to calculate loss of permeate.

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 to either a 115 VAC, 60 Hertz or 220 VAC, 50 Hertz single-phase power supply. The RO control circuit should always be installed on at least a 15 Amp, single-phase dedi- cated circuit. Reverse osmosis machines with 115 VAC, single-phase control voltage include an eight-foot (2.4 m) cord which plugs into a three-prong grou

and complies with local and national electrical codes, move onto Section 2.10 (Pretreatment for Water Purification). NOTE: External control contacts are normally closed, dry contacts. 2.10 Pretreatment for Water Purification A water analysis of your feed water should have been performed, as part of the plan- ning and engineering that went into developing your RO system. The water analysis will provide information on what type of pretreatment may be required and what recovery the machine can be r

6. Turn the ON/OFF button on the machine ON. System will open allowing water to flow through the machine to the drain through the permeate and concen- trate CIP valves. Let the machine run to drain for 5 - 10 minutes. This provides a wet start-up of the pump and removes any air in the system. 7. Turn the ON/OFF button on the machine to the OFF position. 8. Re-energize the pump power and trigger the ON/OFF button on the machine to check rotation of the pump motor. Observing from the back of th

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 Specifications 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). The proper adjustment of the recycle and concentrate valves are critical to the correct operation of the machine. CAUTION: Optimum recovery will vary according to water quality. 2.13 T

2.15 Autoflush Timer 2.15.1 Programming the Autoflush Timer The Autoflush timer clock operates 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. This provides extra cross flow which flushes the loose foulants from the surface of the membrane elements. When the machine is operating in the Autoflush Mode a slight drop in permeate production,

2.16 Calibrating the Conductivity Probe STEPS 1. Make sure the calibration meter is in Measure Mode (with the MEAS 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 to stabilize. 4. Calibrate the meter by adjusting the CAL adjustment screw until the Liquid Crystal Display (LCD) display reads 13 mS of the solution. The meter is now calibrated NOTE: The alarm function on the conduct
