1. INTRODUCTION
1.1.LX Product Family Overview
Ionpure LX modules are medium flow rate CEDI devices. Their compact state-of-the-art
design assures ease of installation, maintenance, and service. LX modules are available
in the following sizes:
Size Nominal Flow Description
IP-LXM04 2.0 gpm (0.45 m3/h) 4-cell
IP-LXM10 5.0 gpm (1.14 m3/h) 10-cell
IP-LXM18 9.0 gpm (2.05 m3/h) 18-cell
IP-LXM24 12.5 gpm (2.84 m3/h) 24-cell
IP-LXM30 15.0 gpm (3.4 m3/h) 30-cell
IP-LXM45 22.5 gpm (5.1 m3/h) 45-cell
For more information on the LX module specifications and flow rates, see Section 2.4 and
Appendix A of this Manual.
There are four different types of LX modules (see Appendix D), each of which is available
in the six sizes listed above:
EU-4 For European Pharmacopeia (EP) applications
HI-3 For U.S. Pharmacopeia (USP) applications, hot water sanitizable (HWS)
X-4 For USP, NSF (drinking water) and general use (worldwide) applications
Z-5 For General Industry, with improved Cl2tolerance

1.2.Using This Manual
Service technicians should review this manual prior to going to the installation 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 LX
modules. It also contains information on basic troubleshooting (See Section 7).
IONPURE strongly recommends all users read the entire contents of the manual. If the
LX module is not operating properly after going through the basic troubleshooting
exercises, contact your Local Service Provider.
1.3.Installation Precautions
·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 TO THE DC
POWER SUPPLY HAS FIRST BEEN DISCONNECTED AND
LOCKED OUT ACCORDING TO STANDARD LOCKOUT/
TAGOUT PROCEDURES.
·To minimize the possibility of electric shock, confirm that all ground
wires are properly connected.
·Do not open the LX module. Opening the module will void the
warranty and cause irreversible damage.
·The module must be operated according to the design
specifications for temperature and humidity.
·Metal piping should never be connected directly to the module.
Non-metallic piping adapters are required at the module inlets and
outlets. It is then allowable to transition to metallic piping.
·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.
·Because LX 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.
IONPURE ®LX CEDI Modules
Page 9 IP-MAN-LX-1220-EN.pdf
·Always flush out the piping to remove any debris before operating
the LX module.
·Installation of the LX 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 LX MODULE UNTIL PROPER
FLOW AND PRESSURE HAVE FIRST BEEN CHECKED AND
VERIFIED.
·Never block off (dead-head) the LX outlets. Dead-heading the
outlets can result in over-pressurization, leading to permanent
damage.
·Do not operate the module under conditions other than those
stated in the module manual. The prescribed feed water
requirements, 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:
oMake sure all wiring connections are tight.
oTest safety interlocks such as flow switches or connections to upstream
equipment.
oCheck torque on tie bar nuts and tighten as required.
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 valve off or plug all inlets and outlets. This is to minimize
bacteria growth and prevent drying of ion exchange resins during shutdown.

2. PRE-INSTALLATION: PREPARATION & REQUIREMENTS
2.1.Tools Required
·Dolly or forklift to move the module into place
·Cords, cables or straps to secure module to dolly or forklift
·Slip joint pliers, for tightening of plumbing connectors
·Wire cutters/strippers, for wiring connections inside junction box
·Screwdrivers (flat blade and Phillips head) to connect wires at terminal strip
·Adjustable torque wrench with 10-50 ft-lb (14-68 N-m) range, 3/8” (10 mm) drive
·19 mm extra deep socket (Ionpure part number W2T210908)
·19 mm open end wrench
2.2.Unpacking and Moving LX Modules
·After uncrating the module, inspect it for any signs of damage. If damage is apparent,
immediately notify the carrier and your CEDI System Provider.
·The LX modules can weigh 70-330 lbs. (32-150 kg) dry, depending on size, and may
require mechanical assistance for lifting and moving into position. Both LX endplates
have two ¾-10 tapped holes for installation of lifting eyebolts, if desired.
·Ensure that lifting apparatus has appropriate load rating.
