INSTRUCTIONS FOR DISMANTLING VALVE

Shut off hot and cold supplies to valve.

Loosen POINTER SET SCREW, Remove SNAP CAP, SCREW and

WASHER, POINTER and FRICTION SPRING. (FIGURE #1).

Remove the 6 COVER SCREWS, then take off cover to which the

Thermostat and Gears are attached.

WHEN RE-ASSEMBLING VALVE, insert new Flange Packing in

base; replace COVER, tightening COVER SCREWS in rotation; put

FRICTION SPRING in place; then replace POINTER and POINTER

ROD SCREW, WASHER and CAP.

After installing new parts, it will probably be necessary to reset Pointer

to obtain correct temperature range from Cold to Hot. See page 2

instructions "TO RESET ADJUSTABLE HIGH TEMPERATURE

LIMIT STOP."

TO CLEAN PORT SLEEVE ASSEMBLY

Failure to properly blend the water may be caused by a sticking

condition in the PORT SLEEVE ASSEMBLY. The THIMBLE should

slide freely on the PORT SLEEVE.

If a deposit of lime or sediment prevents free movement, use a nail set

or other tapered tool to unscrew the CHECK NUT as far as it will go,

then screw the PORT SLEEVE NUT into the base. This will release the

PORT SLEEVE and THIMBLE so they can be lifted out, (Figure #2).

Clean with a NON-CORROSIVE CLEANING AGENT AND SOFT

CLOTH - DO NOT USE ABRASIVES - then wash parts thoroughly,

wipe with a dry cloth and re-assemble. The PORT SLEEVE should be

assembled with the elongated holes to the right (COLD SIDE). Tighten

PORT SLEEVE NUT against end of PORT SLEEVE but be careful not

to over tighten, this may deform port sleeve. Tighten CHECK NUT.

When replacing front be sure DRIVING BALL is inserted in Ball

Socket as shown in Figure #1.

SCREW, WASHER, POINTER, and FRICTION SPRING. (FIGURE

#1)

Remove COIL SLEEVE STUD and take off THERMOSTAT GROUP.

TO REPLACE (OR CLEAN) THERMOSTAT
