6 Maintenance

6.1 Maintenance Schedule

A MAYTAG Services Qualified Service Technician must perform all maintenance on the MAYTAG

Whole Home Water Filtration System. An annual integrity test must be performed which is required as

part of the 5 year limited prorated membrane warranty.

If the MAYTAG Services Qualified Service Technician determines that System has a high degree of

debris causing a reduction in System flowrate, the number of visits per year may be increased by

MAYTAG to ensure that the System stays within operational limitations set by the MAYTAG Whole

Home Water Filtration System and to ensure the limited warranty protection remains in effect.

The Table below outlines the maintenance schedule that should be followed for each Model of the

MAYTAG Whole Home Water Filtration System.
