Installation Procedure; Calibration Procedure - Toto TSST Installation And Owner's Manual

INSTALLATION PROCEDURE

CAUTION: RISK OF PERSONAL INJURY.
When this valve is installed, it must be calibrated to minimize the risk of
scalding after calibration. The maximum water temperature should never
exceed 120°F (49°C).
1) Turn off the main water supply.
2) Plumb the valve so that outside of
the finished wall lands between
the max and min indicated on the
plaster guard. (i.e. A=2-1/2" to
3-3/4" [65-95mm]. See where "A"
is located on Illustration 2 below.)
3) Connect the hot water supply to
the left inlet marked "H" and the
cold water supply to the right inlet
marked "C".
4) Secure the pipes and the valve to
the frame.
5) Remove the plaster guard from
the valve. Use the plaster guard to
trace the cut-out opening.
6) Reattach the plaster guard to the
valve. Do not remove the guard
again until you are ready to install
the trim.
7) Finish the wall.

After the valve is calibrated, the limiter provides 108ºF (42ºC) at the first
stop position and prevents the temperature from exceeding 120ºF (49ºC) at
the final stop position.
Perform this calibration procedure when you are ready to install the trims.
NOTE: These illustra-
tions show the valve

finishing of the wall.

CALIBRATION PROCEDURE

1) Shut off the hot and cold water supply at
the service stops.

Stop
2) Remove the trim adapter. Check to
make sure the v-groove of the limiter
aligns with the v-groove of the main unit.
If it is not aligned, slide the limiter out
and re-install, making sure to align the
two grooves.
3) Re-install the nut.
4) Turn on the water supply at the service
stops.
5) Turn the water on and let run for about
1 minute. Place a thermometer in the
water stream.
6) Slowly turn the mixing valve stem until
the water temperature is at a constant
104ºF (40ºC).
No t e: After the water temperature is set
at 104ºF (40ºC), do not turn the valve
stem until you have installed the handle
trim. If the valve is turned accidentally,
you will need to repeat the calibration
procedure.
7) Install the handle trim as instructed in
the trim manual.
