TIMER HEAD

Automated
Timer Heads are used on most pre-treatment devices to backwash or regenerate
the

device.

Timer
heads must be checked everyday prior to the first
patient treament to ensure that the

timer
is set to the correct (current) time of day.

To
read the correct time look through the small window. The large white arrow
labeled "Time of Day"

should
be pointing to the correct time of day (make sure that AM and PM are
correct).

If
the time is not correct push the red button in and then turn the wheel until
the correct time is

chosen
and then release the red button.
