Valve as shown in
picture. Make sure both
tubes are clear of ll
valve and ush valve
operation. Ensure hose
clamp is secure.
Slide rubber gasket (P) onto threaded
end of ush valve. Use old gasket if
supplied new gasket does not t.
Secure tank to bowl with bolts (G), rubber
washers (H) brass washers (I) and hex nut (J).
Tank should be level after it has been installed.
NOTE: DO NOT over-tighten. May break tank.

Attach handle lever to tank and hand-
tighten lever lock-nut.
Note: Nut is reverse threaded. Make sure
tabs on collar are oriented vertically.
Line up tabs on lever into the slots on
lever mounting base (B) and snap into
base. Tabs on lever shank need to be
installed vertically.
(1) Reconnect water supply line (V). Use
Step 3.1 chart (on pg. 13) to determine
the appropriate assembly parts required
to properly reconnect the water supply.
NOTE: Hand tighten only. DO NOT use
thread lubricants. Use of thread sealants
or lubricants can damage plastic nut
and result in ooding and property
damage.
If you need to adjust the
orientation of the ush
valve (A), release from
base by (1) turning
counterclockwise until
tabs unlock. (2) Lift
valve out and
adjust/orient as needed.
Turn on water supply. Check for leaks.

Engage the stop (D) to lock the
position of the blue oat (M).
The grey oat controls the full ush. Pull out stop (D) on grey oat (E).
Activate full ush by pushing lever down. If residual water after ush is lower
than line marked in step 1.1, raise grey oat and repeat. If residual water is
higher than line marked in step 1.1, lower grey oat and repeat.
You may be able to save water by moving grey oat upwards.
Test ush - put toilet paper in
bowl and (1) lift lever to ush
toilet. (2) Pull out stop (D) on
blue oat (M) and lower one
step. (3) Engage the stop (D) to
lock the position of the blue oat
(M). Wait for tank to rell before
retesting.
Lower the setting on blue oat (M) one step at a
time until the paper fully ushes. The higher the
blue oat, the more water you save.

(1) Add a gallon of water to bowl.
(2) Wait 10 minutes, allowing water to settle.
(3) Mark water level with a wax pencil.
(4) Flush toilet.
a. If the water reaches your mark in the bowl and the ll valve is still
running, then decrease the water entering the bowl: See step (5).
b. If the valve shuts o before the water has reached your mark in the
bowl, then increase the water entering the bowl: See step (6).
(5) Push down on the roller (Y) and roll it to the next lower number. Repeat
step (4).
(6) Push down on the roller (Y) and roll it to the next higher number. Repeat
step (4).
Continue adjusting in this manner until the water reaches your mark in the
bowl at the same time the ll valve turns o in the tank.
The rell tube (Z) directs water into the ush valve and down into the bowl
during a ush. If too much water enters the bowl, it is wasted going over the
trap and down the drain. The roller clamp (Y) regulates the amount of water
entering the bowl.

Use chart to determine the appropriate assembly parts required to properly reconnect the water supply.
DO NOT use plumber’s putty to seal these fittings (Teflon tape optional). Do not use thread lubricants. Use of thread sealants or
lubricants can damage plastic nut and result in flooding and property damage.
Use Fluidmaster coupling nut
and cone washer to replace
existing parts. Water supply
tube must extend 1/2 inch
inside threaded shank of valve.
Use existing coupling
nut and existing flat
washer.
Use existing spiral

Do not use Fluidmaster's
coupling nut and the
cone washer on plastic or
metal tubing as shown.
CAUTION: DO NOT use CONE WASHER with PLASTIC SUPPLY LINE or METAL SPIRAL TUBING.
CAUTION: Locknut and coupling nut should be hand tightened only! Over tightening locknut or coupling nut could result in
breakage and flooding.
