7. TROUBLESHOOTING
The troubleshooting chart in this Section is a diagnostic guide. If the MX system does
not respond to the recommended solutions, do not attempt further repairs. Call your
Local Service Provider.
Before calling:
• Become thoroughly familiar with the module and all troubleshooting procedures.
• Prepare a list of all problems encountered while operating the equipment.
• Have your monitoring log sheets at hand.
• Have your module’s model and serial numbers at hand. This information can be
found on the end plate on the non-plumbing side (anode). See Figure 1-1.
