Resetting the Dripmaster
There are two ways to reset the Dripmaster:
1. By removing the Dripmaster cover, and raising the Control Mode toggle switch to the MAN
position, and then back to the AUTO position.
2. By disconnecting the power source to the Dripmaster for 5 seconds, and then reconnecting it.
In both cases, the circuit voltage is interrupted and then restored.
Note: In case (2) above, a random drip rate is displayed initially which can be ignored.
