STOP.”
To Clean Port Sleeve Assembly:
To clean port sleeve assembly TAG-1M (fig. 2.): Remove base
stud TA-5. Back off port sleeve nut 3402 as far as it will go into
base. Slide TAG-1M port sleeve assembly toward port sleeve
nut and lift out of valve base. Clean part TAG-1M with a soft
cloth; DO NOT use abrasives such as emery cloth or sandpaper.
After cleaning, wash parts in clean water and reassemble in
valve base. When reassembling port sleeve assembly BE SURE
TO INSTALL WITH SHORT SLOT END IN BASE AND LONG SLOT
END AT PORT SLEEVE NUT. Locate one set of port slots facing
directly toward front of the valve. Tighten port sleeve nut 3402
just enough to hold port sleeve in place, (do not cramp or dis-
tort port sleeve by exerting excess size pressure when tighten-
ing port sleeve nut).

clean it off with a brush in cleaning solution and wash well
before reassembly. Cleaning solution should be non-corrosive
and grit free. To reassemble: be sure, port sleeve assembly is
in place and is working freely from side to side. Reinstall base
stud TA-5, then place thermostat group 6810 on base stud and
BE SURE DRIVING BALL ON PORT SLEEVE ASSEMBLY TAG-1M IS
INSERTED IN HOLE ON LOWER COIL BRACKET (DWG 3.) Move
thermostat back and forth to be sure all parts are free. Replace
cover on valve base, install the four cover screws, and turn on
hot and cold water supplies. See instructions below “To Reset
High Temperature Limit Stop” to properly reset limit stop.
After installation, adjustment, and cleaning, always check the
temperature of the valve when turned to full HOT per the
warning on the front page, using a thermometer. Also check
and if necessary adjust the temperature of the hot water
source. EXCESSIVELY HOT WATER (OVER 90ºF) IS DANGEROUS
AND MAY CAUSE SCALDING!!
