⚠ WARNING: Do not use plumber’s putty, pipe dope, or any other sealant on the water supply connection to this tank. If the connection leaks after hand tightening, replace the supply line. If the connection continues to leak with the new supply line, replace the fill valve. Warranty is void if any type of sealant is used on the water supply connection.
ADJUSTMENTS
-
a. Adjust water level. Water level should be adjusted to level indicated on tank by adjusting float cup.
See Step 11 for water level adjustment method -
b. If bowl fails to siphon, an adjustment may be required with the lift chain. Simply remove the bead chain from the retainment clip (see Fig. 10A) and take up slack on the chain, and reinsert on lift rod. Make sure the chain is not too taught.
Turn on water supply. Submerge the FLOAT CUP under the water for 30 seconds. Adjust the water to desired level by turning WATER LEVEL ADJUSTMENT ROD and moving FLOAT CUP up or down.
CARE AND CLEANING
When cleaning your toilet, wash it with mild, soapy water, rinse thoroughly with clear water and dry with a soft cloth. Avoid detergents, disinfectants, or cleaning products in aerosol cans. NEVER use abrasive scouring powders or abrasive pads on your toilet seat. Some bathroom chemicals and cosmetics may damage the seat’s finish.
⚠ WARNING: Do not use in-tank cleaners. Products containing chlorine (calcium hypochlorite) can seriously damage fittings in the tank. This damage can cause leakage and property damage. American Standard shall not be responsible or liable for any tank fitting damage caused by the use of cleaners containing chlorine (calcium hypochlorite).
NOTE: Pictures are representative and may not exactly depict the flush valve.
Always use quality Fluidmaster repair parts when maintaining your Fluidmaster products. Fluidmaster shall not be responsible or liable for any damages caused by products used with Fluidmaster valves that were not manufactured by Fluidmaster, Inc.
TROUBLESHOOTING
IF FILL VALVE SHUTS OFF BUT CONTINUES TO LEAK SLOWLY, repeat Step 13. IF FILL
VALVE TURNS OFF AND ON DURING PERIODS OF NON-USE, it is a signal you are
wasting water because:
- The end of the refill tube is inserted into overflow pipe, below water level in tank. Attach refill tube to overflow pipe using “S” clip provided.
- The flush valve is leaking because it’s worn, dirty or misaligned with tank ball or flapper (replace with a new flapper).
IF FILL VALVE WON’T TURN ON OR SHUT OFF or REFILL OF TANK WATER IS SLOW after valve has been in use for some time, Fluidmaster Model 242 Replacement Seal may be needed.
