6. MAINTENANCE AND TROUBLESHOOTING

The cleaning chemical volumes and flows detailed in this section are for a single VNX module. Multiply

chemical volumes by number of modules in system

This section also lists possible problems and troubleshooting procedures for the VNX module. All

operators and personnel involved with the module should read and become familiar with all maintenance

and troubleshooting procedures.

Operating Data Log Sheet

VNX system log sheets should be filled out daily to provide early detection of problems that could

jeopardize the warranty and potentially damage the module. A typical log sheet is included at the

end of the troubleshooting in Section 7. Because instrumentation may vary depending on the type

of system the module is installed into, this log sheet may not apply to your particular system. The

system manual should contain log sheets more appropriate for your particular system. However,

the items in bold must be filled out to maintain module warranty.

Periodic Maintenance

Perform the following tests at least once every six months. Check the Troubleshooting portion in

Section 7 for any recommendations that are not listed below.

Periodically, the VNX module may need cleaning or sanitization. Cleaning the module removes

scale and resin/membrane foulants.

Before starting any cleaning or sanitization procedure, see subsection 6.7

for recommended cleaning solutions

Do not run a cleaning or sanitizing solution through the system with DC

power to the VNX module. Make sure the DC power is off before cleaning.
