1.5.6. RO Membrane Rejection
E4H reverse osmosis machines use GE Fiberglass Reinforced Plastic (FRP) covered
AG4040F membrane elements. For ordering information refer to the attached Spare
Parts List. See Table 3 below for details.

*Specification is based on a 2,000 mg/L NaCl solution at 225 psi (1,551 kPa) operating pressure, 77°F
(25°C), pH 7.5 and 15% recovery. Individual flux may vary +25%/-15%. Average salt rejection after a
minimum of 24 hours of continuous operation.
2. INSTALLATION
2.1. Mounting
E4H Series machines are equipped with a stand-alone frame, which supports the
machine. At least 45 inches (114 cm) of space should be allowed on each end of the
membrane element housings for removal and loading of membrane elements. If 45
inches (114 cm) are not available, the entire membrane element housing may need to
be removed for membrane element replacement.
2.2. Piping
The E4H comes with threaded NPT fittings.

2.2.1. Inlet Piping
The feed water source is piped to the inlet using 1.5-inch NPT fittings. A CIP system is
supplied with the DLX Model E4H.
FOR ECN MODEL: To install a CIP system, remove plug and install valves on the E-
Series machine as described in Section 2.2.2. If the inlet pressure is in excess of 60
