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 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 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.

ransporting 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.

2.6 Machine Control

2.6.1 Economy Model

To remotely control the Economy Model (ECN) with float switches and/or pretreatment 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 complete 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 pretreatment 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 singlephase 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 requirement 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.

tart-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 provided. If the machine is moved to a different water source, a new water analysis should be taken before operating the machine.

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 chlorine may cause irreversible damage to the Thin-layer composite (TLC) polyamide (PA) membrane elements in your machine. Daily water checks are recommended 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.

ARNING: IMPROPERLY FLUSHED PRETREATMENT MAY

CAUSE SERIOUS RO MACHINES PROBLEMS AT START-UP.

ARNING: NEVER OPERATE THE MACHINE WITH THE CON-

CENTRATE OR PERMEATE LINES BLOCKED. SEVERE DAMAGE TO THE UNIT MAY RESULT.

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).

ARNING

: 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.
