6. MAINTENANCE
The following section details the maintenance procedures for the MX module. It contains
general maintenance information and specific maintenance information for cleaning and
sanitizing the modules.
The cleaning chemical volumes & flows detailed in this section are for a single MX
module. Multiply chemical volumes by number of modules in system.
This section also lists possible problems and troubleshooting procedures for the MX
module. All operators and personnel involved with the module should read and become
familiar with all maintenance and troubleshooting procedures.
6.1. General Maintenance Guidelines
6.1.1 Operating Data Log Sheet
MX 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 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.
6.1.2 Periodic Maintenance
Perform the following tests at least once every six months.
• Check for any water leakage from the module. If leakage is observed, see the
Troubleshooting subsection for possible solutions.
• Periodically tighten all electrical connections (first make sure that
the DC power is off)
• Check calibration of instrumentation
• Test function of critical interlocks such as low flow protection
6.2. Approved Cleaning Procedures
Periodically, the MX module may need cleaning or sanitization. Cleaning the module
removes scale and resin/membrane foulants. The MX modules can be cleaned and
sanitized with five (5) different solutions, depending on what needs to be removed:
• Hydrochloric acid (2%) – for removing scale and metal foulants.
