If space is not available, the entire membrane element housing can be removed for membrane element change-outs. If the membrane element housings are to be removed to change-out the membrane elements, at least 25-inches (65.3 cm) is required at one end of each membrane element housing and 6-inches (15.2 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 psi (2.1 - 4.1 bar). If the feed water pressure with the machine is in excess of 60 psi (4.1 bar) or fluctuates by more than 5 psi (0.34 bar) a pressure regulator should be installed upstream 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. 2.3 Plumbing Connections Connect proper size drain line to the concentrate outlet (Table 2.1, E2/EZ2-Series Machine Piping Connections) and run to an open drain. The drain capacity needs to be large enough to properly drain the feed water flow of the RO. Table 2.1 E2/EZ2- Series Machine Piping Connections CONNECTIONS Inlet inch (cm) 0.38 (0.96) Permeate inch (cm) 0.38 (0.96) Concentrate inch (cm) 0.38 (0.96) 1 2.4 2.4 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 Table 2.2 (E2/EZ2-Series Feed Water Requirements) for feed water information. Table 2.2 E2/EZ2-Series Feed Water Requirements Temperature Typical: 50° - 85°F (10° - 29°C) Limits: 33° - 104°F (0.60° - 40°C) Inlet Pressure Minimum: Maximum: 30 psig (2.1 barg) 60 psig (4.1 barg) Chlorine (continuous feed) 0 parts per million (ppm) Operating pH 5.5 - 8.5 Silt Density Index (SDI) Less than or equal to 5 to minimize membrane element fouling and extend cleaning intervals. Refer to ASTM* Standard D4189. * American Standard for Testing Materials 2.5 Transporting Pure Water (Permeate) to Point-of-Use 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, E2/EZ2-Series Machine Plumbing Connections) for inlet, permeate, and concentrate piping sizes. WARNING: MACHINE DAMAGE MAY OCCUR IF PERMEATE BACK PRESSURE EXCEEDS 60 PSI (4.1 BAR) DURING OPERATION. 2 2.6 2.6 2.6.1 Economy Model To remotely control the Economy Model (ECN) with float switches and/or pretreatment lockout, remove the jumper between terminals 4 and 5 and wire in the float switches or pretreatment components in series. After all field wiring is complete and complies with local and national electrical codes, move onto Section 2.7 (Single-Phase Electrical). NOTE: External control contacts are normally closed, dry contacts. 2.6.2 Deluxe Model To remotely control the Deluxe Model (DLX), with float switches and/or pretreatment lockout, remove the jumper between terminals 2 an...
