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.
