OPERATING MANUAL REVISION HISTORY

EVENT DATE DESCRIPTION

Original publication August 2009 Operation & Maintenance Manual

1. INTRODUCTION

This section contains the following instructions:

•VNX50HH-2 model module overview - Brief introduction to components and models

•Using this Manual - How to use this Manual

•Precautions - Precautions to prevent personal injury or equipment damage during installation

1.1.VNX50HH-2 model module Overview

VNX50HH-2 modules are designed to be installed in either single or multiple Continuous Deionization

VNX systems. Their compact state-of-the-art design assures ease of installation, maintenance, and

service. Compared to the VNX50-2 the VNX5HH-2 module was designed for higher feed water

hardness tolerance. They are differentiated by a green ‘HH” marking on the vessel of the VNX50HH-

2 module. VNX50HH-2 modules are available in the following size:

Part Number Nominal Flow Description

IP-VNX50HH-2 40 gpm (9.1 m3/h) Single VNX module, VNX type

For more information on the VNX module specifications and flow rates, see Sections 2.2, 5.2 and/or

Appendix A of this Manual.

1.2. Using this manual

Service technicians should review this manual prior to going to the site. It

lists tools and materials needed to install the modules. It also outlines the

site information required to prepare for installation.

NOTE: The warranty may be void if installation or operation instructions contained in this manual are not

followed exactly.

This Manual describes the installation, operation, and routine maintenance of the VNX50HH-2 modules.

It also contains information on basic troubleshooting (Section 7).

IONPURE strongly recommends all users read the entire contents of the manual. If the VNX50HH-2

module is not operating properly after going through the basic troubleshooting exercises, contact your

Local Service Provider.

1.3. Installation Precautions

•DO NOT OPEN THE VNX MODULE. OPENING THE MODULE WILL VOID

THE WARRANTY AND CAUSE IRREVERSIBLE DAMAGE

•During operation, the electrode wiring inside the module junction boxes are at high voltage and

present a shock hazard. THEREFORE, BEFORE TOUCHING THE INSIDE OF THE JUNCTION

BOX, CONFIRM THAT AC POWER HAS FIRST BEEN DISCONNECTED AND LOCKED OUT

ACCORDING TO STANDARD LOCKOUT/TAGOUT PROCEDURES.

•To eliminate the possibility of electric shock, confirm that all GROUND WIRES ARE PROPERLY

CONNECTED. Thoroughly read all the information in this manual before operating the VNX model

modules.

•THE MODULE MUST BE OPERATED ACCORDING TO THE DESIGN SPECIFICATIONS FOR

TEMPERATURE AND HUMIDITY.

•IMPORTANT - Pipe sections prepared for installation must be inspected, and be free of debris from

storage or cutting tool particles. This must be done before installation.

•IMPORTANT - Because VNX modules have narrow flow distribution channels, plugging by particles

can cause permanent damage. Always install pressure gauges, sampling ports, sensors, etc. in tee

fittings. Do not drill or tap into piping. After installing gauges, sampling ports, sensors, etc., always

flush out the piping before connecting to the VNX module to remove any debris.

•Installation of the VNX module must be completed in accordance with the procedures outlined in this

manual. If deviations from the prescribed procedures are deemed necessary to achieve the desired

performance, consult your local Service Provider.

1.4. Operating Precautions

•DO NOT APPLY POWER TO THE VNX MODULE UNTIL PROPER FLOW AND PRESSURE HAVE

FIRST BEEN CHECKED AND VERIFIED.

•Allow for proper inlet and outlet connections. NEVER BLOCK OFF (DEAD-HEAD) ALL OF THE VNX

OUTLET pipe connections. Dead-heading by blocking all outlets can result in over-pressurization,

leading to permanent damage.

IONPURE ®VNX50HH-2 CEDI Modules

Page 7 IP-MAN-VNX50HH2

•Do not operate the module under conditions other than those stated in the module manual. The

prescribed feed water and electrical requirements, and flow configurations, must be followed at all

times. If the feed water quality or the product water requirements change, contact the IONPURE

Technical Support department for assistance.

Once every six months:

•Make sure all wiring connections are tight

•Test safety interlocks such as flow switches or connections to upstream equipment

1.5. Shutdown Precautions

•Confirm that the pressure in the unit is relieved until all pressures inside the unit are atmospheric.

(i.e., all pressure gauges should read zero).

•Drain standing water and plug all inlets and outlets.

2. PRE-INSTALLATION: PREPARATION & REQUIREMENTS

This section contains the following pre-installation information:

•Tools and equipment - Tools and equipment needed to install the module

•Module Inspection -Inspecting the VNX module for damage

•Operating conditions -Temperature range, space requirements, electrical connections, feed water

specifications, plumbing and drain requirements

2.1. Tools and Equipment

The following items are required to unpack, position, and install the VNX module:

•Spreader bar mechanism to move the module into place

•Slip joint pliers

•Wire cutters/strippers

•Phillips head screwdriver

Spreader bar

Strapping rated

for at least

1000 lbs (454

kg)

2.2. Electrical and Plumbing Connections

Electrical

An electrical junction box is included and mounted on the VNX 50HH-2 modules. A single conduit

connection is required through a 7/8” thru hole to provide power to the CEDI module.

The junction box follows DC wire color conventions.

•Red +

•Black –

Figure 2-1: Junction Box End of Module

Inlet and Outlet plumbing connections

Ionpure VNX50HH-2 modules have molded PPO end blocks with

FEMALE connections. There are four (4) necessary custom

ACME thread connection points (for more information see

Connection Drawings in Appendix B:

•Product Inlet (Dilute Feed)

•Product Outlet (Product)

•Reject Inlet (Concentrate Feed)

•Reject Outlet (Reject)

Labels (as shown on the right) are used for port identification.

Product water (Dilute out) feeds the Concentrate Inlet.

To avoid the risk of electrical shock, some form of grounding must be used

on any stream where the plumbing is stainless steel or if there are samples

points or instrumentation in close proximity to the module. For sanitary

applications, a grounding cap can be used, Ionpure part number 49/S4501-124, which is actually

a ¾” TC cap with a welded stud to be wired to ground. For non-sanitary applications, a ¼” SS

threaded grounding rod can be used, Ionpure part number ZIVC00160.

2.3. Inspect the Module

•Do not uncrate the module prior to moving it into its final location. After uncrating it, inspect it

for any signs of damage. If damage is apparent, immediately notify your Local Service

Provider and the carrier.

2.4. Operating Requirements

In order to operate to specification, the VNX module must have the following conditions present.

If any of these conditions are unmet, do not attempt to install the VNX module without specific

instructions from your Local Service Provider’s Technical Support.

•Operating Environment

The VNX module requires indoor installation out of direct sunlight.

The maximum ambient room temperature should not exceed 113

°F (45° C). The module can tolerate humidity of up to 90%, as long as

condensation does not occur.

•Space Requirements

The physical dimensions of the VNX Module are given in appendix A. In addition to the

size of the module itself, the arrangement of the piping and electrical connections

determine the amount of space the module needs to operate. This arrangement varies

from site to site, depending on the conditions at a particular location.

•Electrical Requirements

The VNX module requires the following power sources. In all cases the cathodes must be

at ground potential.
