5. Gap Clearance

NOTE: If the toilet does not activate, the gap between the actuator

and the plunger arm may need to be reset. Make sure the trip lever

handle is installed and the trip lever nut is tight. This is a left-hand

thread; turn the nut counterclockwise to tighten.

Make sure the water supply is on and the water from the supply

line has stopped ﬂowing into the toilet.

Loosen the setscrew on the actuator. Do not fully remove the

setscrew.

Turn the actuator until there is a 1/16″ (2 mm) - 1/8″ (3 mm) gap

between the actuator and the plunger arm. Turn the actuator

clockwise to increase the gap.

Retighten the setscrew once the gap is properly adjusted.

IMPORTANT! Loss of gap clearance could cause leakage into the

toilet bowl. The plunger may not seal properly and may cause a

continual ﬂow of water. If the problem is not corrected after

adjusting the actuator, refer to the troubleshooting section in the

Homeowners Guide.
