Thumb Screw
7. Single Control Link Installation
Ensure that the rod is still pushed down to the open position.
From the underside of the bidet, locate the link where the rod is
inserted. Above the adjustment hole, bend the top half of the link
back towards the lift rod. Bend the link until the two holes at the
top of the link are aligned with the lift rod.
From the top of the bidet, pull the lift rod up until it is raised
higher than the link.
Slide the lift rod through the two holes at the top of the link. The
thumb screw should face toward the back of the bidet.
Tighten the thumb screw so the lift rod knob extends 1/16" (2
mm) from the lift rod hole.
Fully raise the faucet handle to the "On" position.
Raise the lift rod to close the drain.
If the knob of the lift rod touches the rear of the faucet handle,
the drain will not close. If that happens, loosen the thumb screw
and lower the lift rod. Tighten the thumb screw after adjustment.
If the drain still does not close, slide the link closer to the body
nut on the drain. Or move the rod to the next higher adjustment
hole in the link. Or bend the link more and slide it closer to the
body nut on the drain.
Tighten the thumbscrew on the link so the lift rod knob extends
1/16" (2 mm) from the lift rod hole.
