2.0 INSTALLATION
2.1 Mounting the Unit
When installing your new GE Infrastructure Water & Process Technologies reverse
osmosis (RO) machine, allow at least 45-inches (114 cm) above the machine for mem-
brane element removal and loading. If space is not available, the entire membrane
element housing can be removed for membrane element change outs. If the mem-
brane 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 main-
tain 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.
