FLUSH OUT THE SYSTEM:
¾ Before installing the cartridge, the supply lines must
be flushed out to prevent clogging of the filter
screens. Failure to flush the lines will permanently
damage the cartridge and void the warranty. Repeat
this process as needed prior to trim installation.
¾ See Figure - 04 for steps 6-10.
6. The VALVE BODY is shipped with the FLUSH PLATE
pre-installed, and is ready for flushing the lines.
7. Turn on the water supply and open the SERVICE
STOPS to flush out the lines then inspect all
connections for leaks.
8. After the lines are flushed, turn off the water supply
and close the SERVICE STOPS, unthread the 2 cover
SCREWS, then remove the FLUSH PLATE.
9. Install the CARTRIDGE using the 2 cover SCREWS
and turn off the SERVICE STOPS.
ROUGH-IN:
1.
Make sure the valve body is positioned according to
valve markings so the inlets are situated with hot
piped on the left and cold piped on the right. See
Figure - 01.
