GETTING STARTED

PARTS OVERVIEW

TOP-DOWN VIEW

STEP 1: PREPARE TANK

A: TURN OFF WATER

B: DRAIN WATER
Flush the toilet to drain most of the water from the tank.

FLUSH

C: USE SPONGE OR TOWEL TO SOAK UP EXCESS WATER IN THE TANK STEP 2 : REMOVE OLD FILL VALVE

A: REMOVE CONNECTOR Remove water supply connector from bottom of fill valve by twisting connector nut to the left (clockwise).

Towel (Optional)

NOTE : Inspect the water supply connector. Replace it if it is worn, or you don’t know how old it is, to prevent flooding and property damage.

B: REMOVE OLD LOCKNUT
Below tank, twist locknut to the left (clockwise) to remove from fill valve. C: REMOVE OLD FILL VALVE

Including refill tube, refill clip, and shank washer. Drain any excess water into the bucket by removing the fill valve from the tank. (Pull fill valve up)

Bucket (Optional)![Fluidmaster 400H-002 Performax Universal Toilet Fill Valve

• REMOVE OLD FILL VALVE](https://manuals.plus/wp-content/uploads/2021/10 /Fluidmaster-400H-002-Performax-Universal-Toilet-Fill-Valve-REMOVE-OLD-FILL- VALVE.jpg) STEP 3 : ADJUST HEIGHT OF NEW FILL VALVE

A: TWIST FILL VALVE TO ADJUST HEIGHT
Top of the fill valve cap should measure roughly 3″ above the top of the overflow pipe when installed.

NOTE:
Increasing height allows more water to fill in the tank.* The top of the overflow pipe must be a minimum of 1″ below tank lever hole.

STEP 4 : INSTALL NEW FILL VALVE

A: ATTACH REFILL CLIP TO OTHER END OF REFILL TUBE

B: INSERT FILL VALVE
Position refill tube to face flush valve making sure fill valve parts do not interfere with the lever arm.

C: ATTACH REFILL CLIP TO OVERFLOW PIPE
Note: If the refill tube is too long to fit inside the tank with the lid closed, remove the refill tube from the fill valve refill port, cut the tube, and reattach to the port. D: INSTALL LOCKNUT
Screw locknut to the right (counterclockwise) onto fill valve shank (below the tank).
Hand-tighten only. DO NOT OVERTIGHTEN. Over tightening may crack the fill valve or tank causing flooding. Make sure the float cup does not touch the tank walls or tank lever and flush valve.

STEP 5: FINISHING STEPS

A: ATTACH WATER SUPPLY CONNECTOR TO FILL VALVE
Twist to the right (counterclockwise) *Hand-tighten only. DO NOT OVERTIGHTEN. B: TURN ON WATER Check for leaks. (Go to www.Fluidmaster.com/support for leak solutions.) TURN COUNTERCLOCKWISE

C: WATER LEVEL
After the tank stops filling, the water level should fill the tank to roughly ½ inch below the top of the overflow pipe to ensure a proper flush. (Does not need to be exact.)![Fluidmaster 400H-002 Performax Universal Toilet Fill Valve

• WATER LEVEL](https://manuals.plus/wp-content/uploads/2021/10/Fluidmaster- 400H-002-Performax-Universal-Toilet-Fill-Valve-WATER-LEVEL.jpg)* Over tightening may damage the fill valve or coupling nut, potentially causing flooding. Make sure the float cup does not touch the tank walls or tank lever and flush valve.
  ** The top of the overflow pipe must be a minimum of 1″ below tank lever hole.

STEP 6: FINE-TUNE TANK WATER LEVEL

A: FLUSH THE TOILET TO CHECK THE TANK WATER LEVEL
After the water stops filling the tank, the water level should be roughly ½ inch below the top of the overflow pipe to ensure a proper flush. See Step 5C for a Full Tank view

B: WATER LEVEL IS TOO LOW
Turn the tank water level adjustment screw clockwise to raise the float. Flush to reset water level.

THE WATER LEVEL IS TOO HIGH
Turn the water level adjustment screw counterclockwise to lower the float. Flush to reset water level.

STEP 7: FINE-TUNE BOWL WATER LEVEL
NOTE : The PerforMAX Fill Valve is pre-set to fill the proper bowl water level in most toilets straight out of the box.

A: FILL BOWL WITH A GALLON OF WATER
Wait 1 minute until the bowl water level recedes down and stops.

B: MARK THE WATER LEVEL IN THE BOWL
With a pencil, draw a line at the top of the water level in the bowl.  (Pencil mark will easily wash off). C: FLUSH TOILET TO CHECK BOWL WATER LEVEL
If the water level matches the line you’ve made in the bowl when the fill valve stops filling the tank, the water level is correct, proceed to Step 8. If the water level matches the line in the bowl and then fill valve is STILL FILLING, then the bowl water is TOO HIGH, proceed to Step 7D. If the valve shuts off and the water level does NOT match the line in the bowl, the water level is TOO LOW, proceed to Step 7D.  STEP 7: FINE-TUNE BOWL WATER LEVEL
D: ADJUST THE BOWL WATER LEVEL
IF TOO HIGH: Turn the dial clockwise. LESS WATERIF TOO LOW: Turn the dial counter- clockwise. E: FLUSH TOILET, CHECK BOWL WATER LEVEL
Repeat Steps 7D and 7E until the water level in the bowl matches the line when the fill valve shuts off. STEP 8 : FLUSH THE TOILET

A: FLUSH THE TOILET If you’re satisfied with the flush, YOU’RE DONE!YOU DID IT!
