· Always flush out the piping to remove any debris before operating
the VNX module.
· 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.
· Never block off (dead-head) the VNX 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:
o Make sure all wiring connections are tight.
o 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 valve off or plug all inlets and outlets. This is to minimize
bacteria growth and prevent drying of ion exchange resins during shutdown.
