FLEX TUBE DIAPHRAGM ASSEMBLY
In early 2003 Sloan introduced the Flex Tube Diaphragm kit into the OPTIMA
Plus. This design completely replaced the old OPTIMA Plus Diaphragm Kit
that featured the metal shaft with the Quad Ring. This change further
improved the reliability of the OPTIMA Plus as it replaced a wearable
dynamic seal (the Quad Ring) with a non-moving static O-ring seal.
The Flex Tube Diaphragm Kit also features Sloan's exclusive Dual Filter
Diaphragm. The Dual Filter Diaphragm helps to protect the valve from water
bourn sediment that can cause the valve to stick open and run on. The Dual
Filter diaphragm is also made from Sloan's Permex Synthetic Rubber
material for resistance against chloramines and other water treatment
chemicals.

ADJUSTING THE OLD STYLE INSIDE DIAPHRAGM ASSEMBLY
The Inside Diaphragm Assembly was set at the factory to ensure an
accurate flush cycle over a range of water pressures.
If adjustment is required, remove the Inside Diaphragm Assembly and turn
it upside down. Inside the Assembly Guide is an Adjustment Screw. Insert
a slotted screwdriver and turn the Adjustment Screw according to the
Conversion Guidelines.
Turning the Adjustment Screw
clockwise DECREASES the flush
volume.
Turning the Adjustment Screw
counterclockwise INCREASES
the flush volume.
For full adjustment procedures,
see OPTIMA Plus Conversion
Guide #0816511.
