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 the pump motor, pump rotation should be clockwise. If rotation is wrong, de-energize the pump voltage from the source and switch any two of the three-phase wires coming in on top of the three-phase starter. Re-energize the pump voltage and re-check, to ensure correct rotation for the start-up and operation of your machine. WARNING: IF THE RO PUMP IS STARTED WITH INCORRECT ROTATION (i.e., BACKWARDS), A NOTICEABLE DROP IN FLOWS AND PRESSURES WILL RESULT. IF PUMP MOTOR OPERATES BACKWARDS FOR ANY LENGTH OF TIME, PUMP DAMAGE MAY RESULT. After correct rotation has been verified, you are now ready to start the machine and set the flows and pressures. 9. With the recycle and concentrate orifices still two (2) turns open and adequate feed water available, start the machine by turning the ON/OFF button to the ON position. 10. As the pump starts to build pressure, begin to adjust the orifices in the following manner: start by slowly closing the concentrate orifice while slowly opening the recycle valve. Primary Pressure for Normal Operation at 77°F (25°C) E4-Series: 220 psi (15.2 bar) at 77°F (25°C) EZ4/E4LE-Series: 115 psi (7.9 bar) at 77°F (25°C) While you are doing these valve adjustments, to obtain correct flows and pressures, observe the primary or pump pressure. The pump pressure, while adjusting the orifices, should never operate outside of these ranges: E4-Series Range: 190 - 275 psi (13.1 - 19.0 bar) EZ4/E4LE-Series Range: 100 - 140 psi (6.9 - 9.6 bar) 8 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). 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). CAUTION: Optimum recovery will vary according to water quality. 2.13 Temperature Correction Factor If the temperature of the inlet feed water is not 77°F (25°C), refer to Technote 113 for Temperature Correction Factors. NOTE: Optimum recovery will vary according to water quality. 9 2.14 2.14 The machine flow specifications listed below are based on 25°C (77°F).

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, as well as a decrease in the primary and final pressures may be observed. An ideal way to set the timer up is to program ten Autoflush sequences, with a 10 to 15 minute duration, per 24 hours. To do this, follow the procedure below. 2.15.2 Setting Up the Autoflush Timer Clock IMPORTANT: Before proceeding with setting the timer and programming the unit, press the RESET KEY to clear all data. After pressing the RESET KEY, the display may show A.M., this is in military time mode. If the machine is in Military Time, do the following: SELECTING AM/PM OR MILITARY TIME After pressing reset, the display may show A.M.(right). The numbered day symbols will be flashing ON and OFF. If the display does not show A.M., it is in military time mode (24:00 hr.). To change to A.M./P.M. mode, press and hold the h Key and press ± 1h Key once, A.M. will appear in the display. If display is in A.M.. mode and military mode is desired, press and hold the h Key, press the ± 1h Key once. Figure 2.2 Setting-Up the Correct Time on the Autoflush Timer 11 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. NOTE: If the h and m keys are held down for longer than 2 seconds, the numbers will advance rapidly. If the days are flashing, it indicates the day of the week was not set when setting the...
