INSTALLATION PROCEDURE

1. Open the Unifit Rough-In packaging. Follow the Unifit Rough-In Installation instruction to complete the rough-in installation (ill. 1).

2. Place the template into position and follow its instructions to prepare for installing the toilet bowl.
   NOTICE Do not move the Unifit Rough- In on the Floor Flange after wax seal is set. If this notice is disregarded, discard the wax ring and replace with new wax ring.

3. Place the toilet bowl over the Unifit Rough-In and the two mounting blocks, by aligning the bowl outlet with the Unifit Rough-In opening (ill. 2).
   NOTICE Insert the toilet all the way into position. If this notice is disregarded, leakage may result.
   NOTICE Check for rocking. If needed, use shims to prevent the toilet from rocking.

4. Align the toilet perpendicular to the back wall and parallel to side walls; it should not sit crooked or diagonal (ill. 3).

5. Install the side screws to the mounting blocks. Cover the screw head with the provided screw caps (ill. 4).

6. Install the tank-to-bowl mounting hardware to the tank (ill. • 5).
   CAUTION Do NOT overtighten- hardware, as it may break the china and cause personal injury or property damage.

7. Place the tank upside down onto some padding. Inspect the smaller fill valve nut and larger flush valve nut for a secure connection (ill. 6).
   Try to tighten the nuts with your hands. If loose, tighten the nut hand tight and an additional 1/4 turn for the smaller fill valve nut and an additional 1/2 turn for the larger flush tower nut.
   NOTICE Make sure that the fill valve does not turn and hit the tank while tightening.

8. Connect the water supply hose (not provided) to the fill valve (ill. 5).
   NOTICE The water supply hose must be connected to the fill valve BEFORE the tank-to-bowl installation. TOTO recommends using a longer flexible supply hose.

9. Connect the water supply hose (not provided) to the fill valve (ill. 5).
   NOTICE The water supply hose must be connected to the fill valve BEFORE the tank-to-bowl installation.
   TOTO recommends using a longer flexible supply hose.
   Place the tank-to-bowl gasket onto the flush tower nut (ill. 7).
   While pressing down, spread the gasket over the nut until the gasket touches the bottom of the tank. A slight gap between the tank bottom and the gasket is allowable.

10. Pick up the tank and carefully guide the water supply hose over the bowl’s fill valve hole, align the tank- to-bowl gasket over the inlet of the bowl, and align the tank bolts over the bolt holes of the bowl.

11. Using provided tank-tight nuts, hand tighten the nuts evenly until tank sets snugly on each of the 3 contact points on the bowl (ill. 8).
    CAUTION Do not overtighten the mounting bolts. Overtightening may break the china and cause personal injury and/or property damage.

12. Install the flexible water supply hose to the angle stop (ill. 9). Make sure that the hose is free of kinks.

13. On the underside of the tank lid, remove the 2 rods with lock nuts, and screw them clockwise to the push button assembly. Place the lid on top of the tank, making sure that the full flush push button is on the left side (ill 10).

14. Adjust the length of the rods. If the push button rods are too short (see ill. 11a), the push buttons will not sit properly and toilet may short flush. If the push button rods are too long (see ill. 11b), the push button may continuously activate the flush valve.
    Correct with the following steps:

15. Loosen the lock nuts counter- clockwise.

16. Turn the rods clockwise to shorten, counter-clockwise to lengthen (each full turn is 1mm).

17. Place the lid on the tank to check theadjustment.

CARE AND CLEANING

Use a detergent or non-abrasive toilet cleaner and a soft bristled plastic brush to clean your toilet. To remove hard water stains, use vinegar or lime dissolving cleaner and a non-scratch scour pad made for porcelain. Allow a little contact time to allow the cleaner to dissolve the buildup.

NOTICE
DO NOT USE IN-TANK BOWL CLEANERS.
The use of high concentration of chlorine or chlorine-related products can seriously damage fittings in the tank. This damage can cause leakage and property damage. TOTO shall not be responsible or liable for any tank fitting failure or damage caused by the use of in-tank bowl cleaners.

REPLACING THE FILL VALVE

1. Shut off the water supply. Flush the toilet and remove any remaining water from the tank. Reverse the tank installation instructions to remove it from the bowl. Remove the old fill valve.

2. Install new fill valve by sliding the threaded portion of the shaft through the hole in the bottom of tank.

3. Thread mounting nut onto exposed shaft under the tank and tighten nut.
   CAUTION Do not over-tighten.

4. Connect the water supply (see ill. 1). Pipe dope is not recommended. Attach the refill tube to the valve and clip the other end to the overflow pipe.

ADJUSTING THE WATER LEVEL

Refer to the water level line stamp inside the tank.

1. The water level adjustment is located in the top end of the fill valve. Use a flathead screwdriver to make adjustments:
   • To raise the water level: turn the screwdriver clockwise, or towards the ‘+’ indicator.
   • To lower the water level: turn the screwdriver counter-clockwise, or towards the ‘-‘ indicator.
2. Flush after each adjustment to check the water level. When satisfied with the water level, flush once more to verify.

SERVICING THE FILL VALVE

NOTE: Due to water conditions in your area, the strainer may require periodic cleaning. An indication that the strainer requires service can be seen in a delayed fill cycle, intermittent fill cycle, or inadequate amount of water flow from the refill tube.

2. Pinch the tabs of the lever arm to allow its removal (see ill. 2).
