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.

2.3 Installing Clean-In-Place Valves
NOTE: Clean-In-Place (CIP) valves are not included with 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 flush-
ing at start-up.
WARNING: NEVER OPERATE THE MACHINE WITH THE CONCENTRATE OR PER-
MEATE 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.

2.6 Transporting Pure Water (Permeate) to Point-of-Use
The pure water, or permeate, is in an aggressive state and should only be transport-
ed 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 concen-
trate piping sizes. Refer to Connections (Table 2.1) for inlet, permeate, and concen-
trate piping sizes.
WARNING: MACHINE DAMAGE MAY OCCUR IF PERMEATE BACK PRESSURE
EXCEEDS 60 PSIG (4.1 BARG) DURING OPERATION.

Refer to ASTM* standard D4189.
2.7 Pressure Correction Factors
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

Factors
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.

2.8 Electrical
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 dedi-
cated 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 machines shipped with a
220 VAC, single-phase control circuit are shipped with an eight-foot
electrical cord, but customers must provide electrical plug.
2.8.2 Three-Phase Electrical
The three-phase pump motor requires a 15 AMP dedicated circuit.
Always verify correct voltage and Amp rating by checking voltage tag
on the starter box or by checking electrical specifications on the
pump. The motor is wired for 460 Volts, 60 Hertz, three-phase voltage
from the factory (Figure 2.1, Three-Phase Allen Bradley Motor Starter).
The pump motor can be rewired to 208 or 230 Volts. If this is done, a
wiring change must be made internally in the pump motor and a
higher amperage relay and starter may need to be installed. All field
wiring must comply with applicable local and national electrical
codes.
After checking the voltage tag on the motor starter to ensure the
available voltage and amperage are correct, connect the provided
three-phase power to the motor starter (Figure 2.1). This can be done
by connecting the three phase power to the top of the starter relay
terminals: L1, L2, and L3. A separate, fused disconnect for the motor
wiring with proper protection for the Horsepower and Amp draw of
the motor is recommended. All field wiring must comply with applic-
able local and national electrical codes. See Figure 2.1 for three-
phase Allen Bradley Starter Hook-Up.
