6. Flush the Piping

Disassemble the valve as shown to remove the internal

components.

Slowly open the water supplies to run water through the supply

piping and valve body to remove any debris.

Inspect the two inlet seals of the pressure balancing unit (PBU). If

the seals are damaged, replace them with the provided extra inlet

seals. Lubricate the seals using the capsule provided.

To reinstall the PBU, push it into the valve in the initial install

position with the nuts on the PBU toward the hot inlet. Make

sure the PBU seals do not come in contact with the inlet/outlet

holes during initial installation because their rough edges may

damage the seals.

Rotate the PBU counterclockwise while applying downward

pressure until it is seated in the seating indents on the bottom of

the valve. The PBU should not rotate when it is properly seated.

Reassemble the remaining valve components as shown.
