Reassembly
Properly orient the cartridge, see illustration above, then re-insert cartridge by pushing it all the way into the body until the front of the ears on the cartridge
shell are flush and aligned with the top and bottom of the valve body. Replace the retainer clip so that the legs straddle the cartridge ears and slide down into
the bottom slot in the body. This prevents the cartridge from rotating and locks it in the body. Reinstall stop tube and parts. Limit stop must be installed with
offset at TOP (12 o'clock) position to obtain maximum hot water. The notched flat on the stem must point DOWN when mounting the handle.
To Adjust Temperature Limit Stops
CAUTION: Due to seasonal temperature change of the cold water supply, the temperature limit must be readjusted accordingly to maintain
the desired maximum discharge temperature.
1. Rotate the handle counterclockwise to the stop, let the water run for several minutes to purge cool water from the hot water supply line, check
the hot water temperature.
2. Rotate handle clockwise to off. Remove handle parts, see "Disassembly" and temperature limit stop, rotate the stop clockwise to decrease
(counterclockwise to increase) maximum hot water temperature and reinstall into key stop.
3. For handle styles A & B replace handle, for style C replace handle adapter, do not use handle screws.
4. Rotate the handle or handle adapter counterclockwise to the stop, recheck maximum hot water temperature.
5. Repeat steps 2,3 & 4 until desired maximum temperature is achieved. Install handle parts, see Handle Attachment under "Trim" on following page.
