Control Unit
Adjust the Induction Distance
NOTE: The induction distance is set to a maximum and will not
usually require adjustment. However, if a toilet or any other fixtures
are nearby, adjustment may be needed.
NOTE: The unit is set to adjustment mode for 10 minutes after the
batteries have been inserted. In adjustment mode, the urinal will not
flush, but the battery indicator lamp will flash once when a user is
detected. If adjustment takes longer than 10 minutes, remove and
reinsert the batteries.
Lift the control unit out from the tank.
Remove and retain the plug cover on the control unit to reveal
the distance potential screw.
NOTICE: Only use a micro Phillips screwdriver when adjusting the
induction distance. If the tip of the micro Phillips screwdriver is too
large, the potentiometer may become damaged.
Using a micro Phillips screwdriver, turn the distance potential
screw to adjust the induction distance. To increase the distance,
turn the screw counterclockwise. To decrease the distance, turn
the screw clockwise.
Reinstall the plug cover.
Place the control unit back into the tank.
