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.

2.4 Feed Water Requirements
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
* 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 PRES-
SURE EXCEEDS 60 PSI (4.1 BAR) DURING OPERATION.

2.6 Machine Control
2.6.1 Economy Model
To remotely control the Economy Model (ECN) with float switches and/or pre-
treatment 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 com-
plete 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 pre-
treatment lockout, remove the jumper between terminals 2 and 3 and wire in the
float switches and pretreatment in series. After all field wiring is complete and
complies with local and national electrical codes, move onto Section 2.10
(Pretreatment for Water Purification).
NOTE:External control contacts are normally closed, dry contacts.
2.7 Single-Phase Electrical
Always check voltage tag on the machine to ensure the correct voltage and amperage is
available.
The E2/EZ2-Series machines are shipped as either 120 Volt 60 Hertz or 220 Volt
50 Hertz from the factory. Machines should always be connected to a 15 Amp single-
phase dedicated circuit. The circuit provided should be a separately fused disconnect with
the proper protection for the Hp and Amp draws of the machine. Reverse osmosis (RO)
machines with 115 Volt circuit include an 8-foot (2.4 m) electrical cord which plugs into
a single-phase outlet. All machines shipped with a 220 VAC single-phase power require-
ment are shipped with an 8-foot (2.4 m) electrical cord, but customers must provide
electrical plug. All field wiring must comply with applicable local and national electrical
codes.
2.8 Machine Start-Up Preparations
2.8.1 Pretreatment for Water Purification
A water analysis of your feed water should have been performed, as part of the
planning and engineering that went into developing your RO system.
The water analysis will provide information on what type of pretreatment may be
required and what recovery the machine can be run at on the feed water provid-
ed. If the machine is moved to a different water source, a new water analysis
should be taken before operating the machine.
3
Your RO is designed to operate on softened tap feed water with an SDI of 5 or
less. The pH should be in a range of 5.5 - 8.5. Exposure to any levels of chlo-
rine may cause irreversible damage to the Thin-layer composite (TLC) polyamide
(PA) membrane elements in your machine. Daily water checks are recommend-
ed to ensure the integrity of your pretreatment and RO system. Refer to
Table 2.2 (E2/EZ2-Series Feed Water Requirements).
2.8.2 Machine Start-Up Preparation
Check the function and integrity of your pretreatment equipment. Ensure that
your water softener and activated carbon filters have been leaked checked and
properly flushed, before starting up your RO machine.
WARNING: IMPROPERLY FLUSHED PRETREATMENT MAY
CAUSE SERIOUS RO MACHINES PROBLEMS AT
START-UP.
WARNING: NEVER OPERATE THE MACHINE WITH THE CON-
CENTRATE OR PERMEATE LINES BLOCKED.
SEVERE DAMAGE TO THE UNIT MAY RESULT.
2.9 Machine Start-Up
STEPS
1. Turn the feed water supply to the machine ON, while checking for leaks in the
pretreatment and inlet feed water lines.
2. Check to ensure power to the motor is de-energized and the ON/OFF button, on
the machine, is in the ON position.
3. Plug in the factory-supplied power cord.
NOTE:Fifty (50) Hertz models require customer supplied plug compatible
with existing outlet.
4. For initial start-up, redirect the permeate and concentrate lines to the drain for
start-up flush.
5. Open the concentrate and recycle flow control valves two (2) complete turns.
These valves are positioned on the flow control plumbing (Figure 2.1, Flow
Control Center).
WARNING: ONCE MACHINE IS OPERATING, FLUSH CONCEN-
TRATE AND PERMEATE TO THE DRAIN FOR
20 - 30 MINUTES. FLUSHING ENSURES ALL BIOCIDES
AND CONTAMINATES ARE REMOVED FROM THE
MEMBRANE ELEMENTS.
4
6. Turn the ON/OFF button on the machine ON.
7. As the pump starts to build pressure, begin to adjust the valves in the following
manner: start by slowly closing the concentrate valves while slowly opening the
recycle valve (Figure 2.1, Flow Control Center).
CAUTION:Monitor machine to ensure inlet pressure of 30 - 60 psi
(2.1 - 4.1 bar) is maintained during operation.
8. After 20 - 30 minutes of flushing permeate to the drain, ensure all chemical
residue has been removed before hooking up to point of use.
While operating, the pressure range should never operate outside of the pressure
ranges displayed in Table 2.3 (E2/EZ2-Series Primary Pressure Range).
Table 2.3
E2/EZ2-Series
Primary Pressure Range*
* Primary pressure temperature for normal operation is 77°F (25°C).
CAUTION:The E2/EZ2-Series must not operate outside the ranges listed
above.
NOTE: Optimum recovery will vary according to feed water quality.
The concentrate valve is drilled, and when completely closed the machine is run-
ning at the correct concentrate flow for a 75% recovery (Table 2.4, Flow
Specifications for E2/EZ2-Series Machines).
If the temperature of the inlet feed water is not 77°F (25°C) use the Temperature
Correction Factor Table (Technote 113). The proper adjustment of the recycle and
concentrate valves are critical to the correct operation of the machine.

9. Complete the Start-Up Data Sheet (Technote 101). The Start-Up Data Sheet and
the Daily Log Sheet (Technote 106) are invaluable in diagnosing the performance
of the equipment, and must be be kept for reference. If you have questions con-
cerning the operation of your machine or the method of data recording, contact
your distributor or the manufacturer.
Figure 2.1
Flow Control Center
CAUTION: Once the machine is running, with orifices, adjust pressures and
flows to the correct measure, flush machine to drain for
30 - 45 minutes.
CAUTION:The E2/EZ2-Series machines are designed to run at 50% recov-
ery. To confirm flows are correct, check Table 2.4 (Flow
Specifications for E2/EZ2-Series Machines). To correct any
temperature variations, check Table 2.4. If your E2/EZ2-Series
machine is operating under permeate back pressure to point of
use, refer to Table 2.5 (E2/EZ2-Series Permeate Back Pressure
Correction Factors).
CAUTION:Machine performance is based on a feed water temperature of
77°F (25°C). If feed water temperature is other than
77°F (25°C), reference Table 2.4 (Temperature Correction
Factors) to confirm machine’s performance
