minute using the controller (refer to step 3) to purge air from the
System. Open the MAYTAG Whole Home Water Filtration System
outlet ball valve to return to service.
Setting the Controller
To reduce the risk of severe injury, illness, death, and/or property damage, read and
follow all instructions. Use only Maytag Whole Home Water Filtration System
authorized parts where required to repair and service the Maytag Whole Home Water
Filtration System.
The Controller is a timing device that automatically opens the automatic drain valve to provide daily flushing and
prevent accumulation of solid material that would result in premature System fouling.
The MAYTAG Whole Home Water Filtration System is equipped with either a Base Controller (Models
MWF4100AWS and MFW4200AWS) or Advanced Controller (Model MWF4300AWS). The Advanced controller
includes the added feature of automated inlet (solenoid) valve control. This feature provides the most thorough
flushing by completely draining the system.
See Table 5 or 6 Controller Program Selection for a description of the various program choices available
with each Controller.
