2.3. Electrical and Plumbing Connection Requirements
· An electrical junction box is included with all VNX modules, mounted on one of the
VNX endblocks. A single conduit connection is required through a 7/8” (22 mm)
through-hole to provide power to the CEDI module.
· Connection of the DC power supply to the VNX module requires 12 AWG (3.31 mm
2
)
wire. All wiring should be done in accordance with local electrical codes.
· Ionpure VNX modules have cast metal end blocks with four (4) custom, ACME-thread
FEMALE connection points. These require special plumbing adapters or plugs,
constructed to the drawings provided in Appendix B. The 4 connections are:
o Product (Dilute) Inlet
o Product (Dilute) Outlet
o Reject (Concentrate) Inlet
o Reject (Concentrate) Outlet
· The VNX modules are shipped with PVC piping adapters with 1-1/2” SOC connections
o Kit model number IP-VNX-CK-PVC-2, part number W3T17350
· Optional polypropylene adapters with 50 mm butt weld connections are available
o Kit model number IP-VNX-CK-PP-2, part number W3T17348
· 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 near the module.
o For sanitary applications, a grounding cap can be used, Ionpure part number
W3T83436, which is actually a ¾” TC cap with a welded stud to be wired to
ground.
o For non-sanitary applications, a ¼” SS threaded grounding rod can be used,
Ionpure part number W2T211647.
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.
2.4.1. Operating Environment
The VNX module requires indoor installation out of direct sunlight. The maximum ambient
temperature should not exceed 113 °F (45° C). The module can tolerate humidity of up
to 90%, as long as condensation does not occur.
2.4.2. Space Requirements
The physical dimensions of the VNX modules are given in appendix A.1. In addition to
the size of the module itself, the arrangement of the piping and the electrical connections
