WARNING
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 tank components.
INSTALLATION WITH FLUIDMASTER
Because drop-in cleaners used in the
8100 BOWL CLEANING SYSTEM
tank can result in damaged tank parts
(see WARNING above), Fluidmaster
"IN"
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
"OUT"
needed. Cartridges supply more than
1,000 flushes and are a snap to replace.
Diagram 2
1. Shut off water supply to tank. Flush tank and sponge out remaining water.
Remove old fill valve assembly and tank lever, using pliers if necessary.
2. If you have a Fluidmaster bowl cleaning system, this will need to be removed
(if you don't have a cleaning system, continue to Step 3). TAKE CAUTION when
removing bowl cleaning system from the tank, as the cleaning agent may drip
from tubes, which can stain hands, clothing and carpets. Carefully disconnect
the tubes from the fill valve and the overflow pipe. Do not disconnect tubes
from the dispenser. Place dispenser unit in a bucket in an upright position.
3. Disassemble small parts – LOCK NUT, SHANK WASHER and ANGLE ADAPTER
for Valve installation (required); CONE WASHER and COUPLING NUT for Water
Supply Connection (optional–see Step 14).
4.Carefully remove CONE WASHER from center of SHANK WASHER. Place SHANK
WASHER on threaded shank of new VALVE. Place flat surface against valve.
5. Unbolt tank from bowl, then lift off tank. Remove washers and nuts from bottom
of tank, then remove old bolts. Remove old gasket.
6. Remove old flush valve, including flapper, using wrench if necessary.
7. When installed, the top of the overflow pipe on the new flush valve should be at
least 1" below the hole in the tank where the tank flush lever is mounted. If neces-
sary, cut the overflow pipe to achieve this height. The critical level mark on the
fill valve (identified by a C.L. mark on the Fluidmaster Fill Valve) should be
at least 1" above the top of the overflow pipe. This is a plumbing code.
8. To adjust the height of the fill valve, twist the threaded shank in or out of valve
body. The height of the valve adjusts from 9 to 14 inches. On some models, a
clicking noise will be heard when adjusting the height. This is normal.
9. Position valve inside tank. Push down on the valve shank (not the top) while
tightening lock nut. Hand tighten only. Make sure float cup does not touch toilet
tank walls, trip mechanism or flush valve.
10. Install new flush valve. Tighten lock nut. Hand tighten only. DO NOT OVER-
TIGHTEN or tank may crack.
11. Slide new rubber gasket (small side down) onto threaded end of flush valve.
12. Install 2 or 3 bolts as follows: Slide rubber washer under bolt head and insert
bolt through tank. Install brass washer, then thread hex nut onto bolt. Carefully
tighten bolt until snug. DO NOT OVERTIGHTEN or tank may crack. Place tank
back on bowl so that rubber gasket fits evenly.
13. Install rubber washer, brass washer, then wing nut onto bolt. Repeat for other
side and back side (if required). Tighten nuts evenly. DO NOT OVERTIGHTEN
or bowl may crack.
14. Before continuing, determine the type of water supply connection you have from
the chart on the left and use the appropriate assembly parts required to properly
reconnect the water supply. DO NOT use plumber's putty to seal these fittings.
15. With correct washers in place (see Step 14), tighten coupling nut. DO NOT
OVERTIGHTEN. CAUTION: DO NOT USE CONE WASHER WITH PLASTIC
SUPPLY LINE.
16. If you have a Fluidmaster bowl cleaning system, reinstall as follows (if you
don't have a cleaning system, continue to Step 17): Hang dispenser where
previously positioned in toilet tank. Be sure toilet tank flushing components
move freely. Attach long tube ("OUT") with clip fastener to the overflow pipe.
Attach other tube ("IN") to fill valve nipple (see Diagram 2).
17. Attach one end of black refill tube to angle adapter and the other end to nipple
located near top of valve. Attach angle adapter to overflow pipe. Trim refill tube
as necessary to prevent kinking. NOTE: Flow from refill tube must be
positioned just above the overflow pipe. Do not insert refill tube into over-
flow pipe. This will siphon water down the overflow pipe, which causes the
valve to turn on and off as it tries to keep the tank full. If the angle adapter
cannot be used, you may need the Model 599 Refill Clamp (not included).
18. Continue to Step 19 for standard front-mount tank. FOR SIDE OR ANGLE-
MOUNT TANK: slowly bend new tank lever arm to match old tank lever arm.
Or, position new tank lever in tank to determine arm angle needed. Remove,
then slowly bend new tank lever arm to match the angle of the tank. DO NOT
BEND ARM TOO QUICKLY OR BACK AND FORTH REPEATEDLY.
19. Measure length of existing tank lever (it should be 4", 6", 8" or 9"). If necessary,
trim new tank lever at the cut line that matches the length of the old tank lever
(hacksaw recommended for best results).
20. Unthread nut from new handle (reverse thread – turn opposite usual direction)
and remove. Slide new tank lever through tank hole until handle shank fits snugly.
Slip lock nut over tank lever (flat side facing handle). Start nut on threads
(reverse thread), but DO NOT TIGHTEN FULLY.
21. Connect flapper chain/linkage to hole in tank lever arm that provides the best lift.
Chain should have slight slack when flapper is in closed position. Replace lid.
Check lift action for proper flush. Tighten tank lever nut securely. DO NOT
OVERTIGHTEN OR TANK MAY CRACK.
8"
22. To adjust flush, begin where the chain attaches to frame as your center point.
Flapper is set at "9" for maximum flush volume. For standard flush volume,
rotate flapper to "4." For less (minimum) flush, rotate flapper to "1." Or, rotate
anywhere in between for the desired flush volume.
23. IMPORTANT: Always clear sand and rust from system. Make sure water
supply is shut off. Remove valve TOP by lifting arm and rotating top and arm
1/8 turn counterclockwise, pressing down slightly on cap.
24. While holding a container over the uncapped VALVE to prevent splashing, turn
water supply on and off a few times. Leave water supply off.
25. Replace TOP by engaging lugs and rotating 1/8 turn clockwise. MAKE CERTAIN
TOP IS TURNED TO THE LOCKED POSITION. VALVE MAY NOT TURN ON IF
TOP IS NOT FULLY TO THE LOCKED POSITION.
26.Turn on water supply. Adjust water to desired level by squeezing water level
adjustment clip and moving FLOAT CUP up or down along stainless steel link.
Check for leaks, then check for proper flush.
