2.0 INSTALLATION
2.1 Mounting the Unit
When installing your new GE Osmonics reverse osmosis (RO) machine, allow at least
45-inches (114.3 cm) above the machine for membrane element removal and loading. 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 prop-
er 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 oper-
ation 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.
