Waterworks .25 Thermostatic Control Valve Trim with Metal Lever Handles - Manual (Page 2)

20.Turn on a wall valve and insert a bladed screw
driver into the square tube (7).
21.Slowly rotate the square tube clockwise to attain
full cold then rotate it counter clockwise to attain
full hot. Verify a full range of temperatures exist.
Note it is approximately 2 complete rotations from
full cold to full hot.
22.Rotate the square tube to adjust the temperature
to the maximum desired bathing temperature and
confirm the setting with a thermometer. Turn off
the water and make sure not to change this
temperature setting.
23.Unthread the 3 set screws (3) from the handle (2).
24.Position the handle so the handle contacts the ball
bearing on the friction post. Note that in this
position, the handle will rest approximately between
4 and 5:00. Push then hold the lever firmly onto
the trim nut and tighten both set screws.
25.Turn on the water and take a reading of the water
temperature. Confirm that the temperature
readings correspond to the hot and cold markings
on the escutcheon plate and if they do not, repeat
the calibration procedures.
26.Rotate the lever to the warm position, i.e. 6:00.
Line up the notch and lever cut outs on the back
side of the trim cover (1) then push the cover onto
the trim plate.
6. Turn on the water supply to flush out the lines.
7. Inspect all connections for leaks.
8. After the lines are flushed, turn off the water
supply. Remove the flush plate (11) and install the
cartridge (10).
ATTACH THE TRIM:
9. Unthread the trim nut (4) from the threaded sleeve
(8) then attach this sleeve to the cartridge (10).
10. Slide the trim plate (6) over the sleeve until the
plate contacts the wall.
11. While holding the trim plate against the wall, mark
the sleeve at a point 3
16
" beyond where it protrudes
through the plate.
12. Remove the trim plate, unthread the sleeve, then
cut the sleeve at the point marked in Step 11. Do
NOT cut the end of the sleeve that has the internal
threads.
13. Re-attach the threaded sleeve and slide the trim
plate over it.
14. Thread the trim nut (4) onto the threaded sleeve
which will hold the plate against the wall.
15. Fully insert the square tube (7) into the trim nut
then by feel, make sure it slides over the stem and
stops against the valve cover plate - see Figure 1.
When seated properly onto the stem, the square
tube will have rotational resistance.
16. Mark the square tube at the point where it passes
through the face of the trim nut.

27.Confirm the high temperature limit completed in
step 24 is functioning properly by turning the handle
counter-clockwise.
28.Temperature settings should be checked periodically
to ensure that proper calibration is maintained.
Changes in the inlet water temperatures could affect
the temperature settings.

Support at 1-800-927-2120 (8am-7pm EST).
17. Remove the square tube and cut it 1
8
" behind the
mark made on the tube in Step 16.
18. After cutting, insert the square tube back into the
trim nut making sure it is slightly recessed into the
trim nut.
CALIBRATION / SETTING THE
TEMPERATURE RANGE
19.The risk of scalding exists until the installer has
properly calibrated the temperature setting.
