FILTER SCREEN REMOVAL AND CLEANING
The valve has filter screens that prevent debris from obstructing the pressure balancing
cartridge. If excessive in-line debris accumulates in the filter screen you will notice a
decrease in flow from the valve. PLEASE NOTE - SHUT OFF BOTH HOT AND COLD WATER

With the cartridge removed the 2 inserts and filter screens can be easily removed
from the valve body.
- Remove the insert by pressing the top corner. This will rotate the insert allowing easy
removal from the valve body.
- There is a place on either side of the filter insert where you can get your finger nail
underneath the filter screen. By pulling the filter screen away from the insert it will
"pop out".
- All debris can be now be easily removed from the filter screen. Replace the filter
screen into the insert and push together gently until it clicks into place.
- Place the insert back into the valve body, making sure the angled edge of the
insert faces out.
The insert should sit flush against the wall of the valve body when properly installed.
