If the membrane 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 membrane element housing and 24-inches (61 cm) behind the machine. 2.2 Plumbing The feed water source must be able to provide water quantity and pressures to maintain an operating feed water pressure of 30 - 60 psig (2.1 - 4.1 barg). If the feed water pressure with the machine is in excess of 60 psig (4.1 barg) or fluctuates by more than 5 psig (0.34 barg) a pressure regulator should be installed up stream of the machine Inlet. If proper water pressure cannot be maintained to the RO, a booster pump may need to be installed in front of the pretreatment to provide the proper water quantity and pressure for the operation of 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 the CIP container during cleaning. CAUTION: If CIP valves are not installed when machine is installed, provisions must be made to bypass permeate and concentrate to drain for flushing at start-up. WARNING: NEVER OPERATE THE MACHINE WITH THE CONCENTRATE OR PERMEATE LINES BLOCKED. SEVERE DAMAGE TO THE UNIT MAY RESULT. 2.4 Concentrate Outlet Connections Connect proper size drain line to the concentrate outlet (Table 2.1) and run to an open drain. The drain capacity needs to be large enough to properly drain the feed water flow of the RO. The maximum concentrate back pressure is 60 psig (4.1 barg) for the RO machine. CAUTION: Operation above 60 psig (4.1 barg) concentrate back pressure may damage the machine. 2.5 Feed Water Requirements The following feed water requirements must be met before installing your new E4 machine to ensure quality permeate and extended membrane element life. Refer to Table 2.2 (E-Series Feed Water Requirements) for feed water information. 2 Table 2.2 E-Series Feed Water Requirements Temperature Typical: 50° - 85°F (10° - 29°C) Limits: 33° - 104°F (0.16° - 40°C) Inlet Pressure Minimum: 30 psig (2.1 barg) Maximum: 60 psig (4.1 barg) Chlorine 0 parts per million (ppm) (continuous feed) Operating pH 5.5 - 8.5 Silt Density Less than or equal to 5 to minimize Index (SDI) membrane element fouling and extend cleaning intervals. Refer to ASTM* standard D4189. * American Standard for Testing Materials 2.6 Transporting Pure Water (Permeate) to Point-of-Use The pure water, or permeate, is in an aggressive state and should only be transported from the machine to the point-of-use in food grade flexible nylon, stainless steel (SS) tubing, or polyvinyl chloride (PVC) material for the inlet, permeate, and concentrate piping sizes. Refer to Connections (Table 2.1) for inlet, permeate, and concentrate piping sizes. WARNING: MACHINE DAMAGE MAY OCCUR IF PERMEATE BACK PRESSURE EXCEEDS 60 PSIG (4.1 BARG) DURING OPERATION. 3 2.7 2.7 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. Table 2.3 Pressure Correction Factors BACK PRESSURE % LOSS OF PERMEATE FLOW PRESSURE CORRECTION FACTOR (PCF) 10 psig (0.7 barg) E4/EZ4 E4LE E4/EZ4 E4LE 5% 10% 0.95 0.90 20 psig (1.4 barg) 10% 20% 0.90 0.80 30 psig (2.0 barg) 15% 30% 0.80 0.70 40 psig (2.7 barg) 20% 40% 0.70 0.60 50 psig (3.4 barg) 25% 50% 0.60 0.50 60 psig (4.1 barg) 30% 60% 0.50 0.40 WARNING: IF PERMEATE BACK PRESSURE EXCEEDS 60 PSIG (4.1 BARG) MACHINE DAMAGE MAY OCCUR. WARNING: INSTALLING A CHECK VALVE WILL PREVENT REVERSE FLOW THROUGH THE MEMBRANE ELEMENT WHEN THE MACHINE IS NOT IN OPERATION. REVERSE FLOW, WHEN THE MACHINE IS NOT IN OPERATION, CAN SEVERELY DAMAGE THE MEMBRANE ELEMENTS. 4 2.8 2.8 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 dedicated 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 grounded receptacle. All machin...
