Prepare Valve for Installation

DO NOT USE IN-TANK DROP-IN TOILET BOWL CLEANERS CONTAINING

BLEACH OR CHLORINE. Use of such products will: (1) RESULT IN DAMAGE to tank

components and MAY CAUSE FLOODING and PROPERTY DAMAGE and (2) VOID

FLUIDMASTER WARRANTY. DO NOT overtighten nuts or tank/bowl may crack.

Fluidmaster Flush ’n Sparkle

Toilet Bowl Cleaning System is recommended for

those choosing to use in-tank bowl cleaners and WILL NOT VOID the FLUIDMASTER WARRANTY because

it will not damage the components.

WARNING

Because drop-in cleaners used in the tank can result in damaged

tank parts (see WARNING above), Fluidmaster recommends the

use of Flush ’n Sparkle

Toilet Bowl Cleaning System (Models

8100, 8200 or 8300). It cleans the bowl without harming tank

parts by isolating the cleaner from the tank water, releasing it

only to the bowl where it is needed. Cartridges supply more than

1,000 flushes and are a snap to replace.

Water-Saving Feature: Roller Clamp

Check bowl water level by flushing toilet. If bowl appears to be full but continues to

fill, the valve may be overfilling the bowl causing excess water to siphon down the

trapway. Adjust amount of water going down into the bowl as follows: Fill the bowl

with a gallon of water. Wait 3 minutes until the bowl water level recedes down and

stops. With a pencil, draw a line at the top of the water level in bowl. Now flush the

toilet. If the valve is still filling and the water is up to the line in the bowl, then the

amount of water going into the bowl is too high and needs to be adjusted. Adjust

the refill by turning the roller clamp with thumb to the next lower number. Flush

the toilet; adjust until water level in bowl is at the pencil mark when the fill valve

shuts off. If valve shuts off and bowl is not full, adjust by turning the roller clamp

to a higher number. Repeat until water in bowl is up to line. “O” on roller clamp

equals no refill to bowl.

Flushing Out the Debris:

Hold

a cup over the uncapped valve

to prevent splashing. Turn water

supply full on and off a few

times. Leave water supply off.

Check for leaks. Tighten nuts

just enough to stop leaking.

Place cap assembly on top of

gray valve body by aligning

cap arm and adjustment rod

next to refill hose.

Press down on top cap rotat-

ing top & arm clockwise to

locked position.

Turn on water supply.

IMPORTANT: Submerge the

float cup under the water for

30 seconds. Adjust water level

by turning water level

adjustment screw. To raise–

turn clockwise; to lower –

counterclockwise.

For your convenience, the roller clamp

and hose clamps are pre-assembled to the

refill hose. Attach one end of hose to refill

clip and slide clip to right side of overflow

pipe. Attach other end of hose to nipple on

fill valve with a slight arching (see picture

to the left). Cut tube if necessary. Squeeze

tabs of hose clamp and move clamp to

end of hose, over the fill valve nipple, then

release tabs. Do not shove refill tube down

overflow pipe. This will cause water loss.

FILL VALVE WILL NOT TURN OFF.

IMPORTANT: Sand and rust move through water pipes. Always clear debris from

water lines. Repeat steps “Removing the Valve Cap Assembly” & “Flushing Out

the Debris”.

FILL VALVE WILL NOT TURN ON.

• If float cup does not drop when flushing the tank: Replace 242 seal if fill valve has

been in use for some time.

• If fill valve is new, check for debris or blockage in system.

• Water supply line is too far inside the shank of fill valve. Insert water supply 1/2" only.

WATER LEVEL IN BOWL IS TOO LOW.

• The refill water may need to be increased. Move roller clamp to a higher number.

• Flapper may be closing too soon. Give flapper chain approximately 1/2" of slack.

• Water level in tank may be too low. Raise water level to 1/2" below top of overflow pipe.

CAUTION

Do not shove refill tube down overflow

pipe. This will cause loss of water from

tank. Make sure end of refill tube is

higher than the water level of the tank.
