Electrical Connection
All Ultramax controllers operate on 12-volt alternating current power
supply. This requires use of the GE Water Technologies supplied AC
adapter. A variety of AC adapters are available for different applications.
These AC adapters are available from your supplier. They include:
120 VAC AC Adapters:
Make sure power source matches the rating printed on the AC adapter.
Controller Location
The Ultramax controllers are designed to be mounted on the valve or
attached to a flat surface. Installations that do not provide easy access to
the valve can have the controller mounted for remote operation.
A remote mount connection, PN 1256257, is available for the Ultramax
Series controller.

hours may cause the controller to lose the time and day settings. When
power is restored, the day and time settings must then be re-entered.
