FLUSH OUT THE SYSTEM:
¾ Wall valves and/or diverters and all shower fittings,
must be fully plumbed and installed prior to flushing
the system. (ALL SOLD SEPARATELY).
¾ 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.
¾ See Figure - 03 for Steps 14-18.
14. The exposed wall valve comes pre-installed with the
flush plate and is ready for flushing the lines.
15. Remove the showerhead and/or handshower (any
fitting with a flow regulator).
16. Turn on the water supply to flush out the lines, then
inspect all connections for leaks.
17. After the lines are flushed, turn off the water supply
and remove the flush plate.
18. Install the cartridge using the 2 cover screws and
turn the service stops off.

TEMPERATURE CALIBRATION:
¾ The risk of scalding exists until the installer has
properly calibrated the temperature setting.
¾ See Figure - 05 for steps 22 - 26.
22. Turn on the water supply and a wall valve to run
water through the valve and insert a bladed screw
driver into the square tube.
23. Slowly rotate the square tube clockwise to attain full
cold, then rotate it counter-clockwise to attain full
hot. Verify a full range of temperature exists. Note: It
is approximately 2 complete rotations from full cold
to full hot.
24. With water running, rotate the square tube to adjust
the temperature to the maximum desired bathing
temperature, verified with a thermometer. Turn the
water off and make sure not to change this
temperature setting.
25. Unthread the handle assembly from the limit stop
assembly and loosen the 4 set screws on the limit
stop.
26. Insert the limit stop assembly onto the trim nut
making sure the limit stop pin (shown removed)
makes contact with the limit stop on the trim plate,
then tighten the 4 set screws.
