CARE AND CLEANING

WARNING!
DO NOT USE IN-TANK BOWL CLEANERS.
The use of high concentrations 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.

BEFORE INSTALLATION

• Read these instructions thoroughly before beginning work.
• Please leave instructions for customers. These instructions contain maintenance and warranty information.
• If necessary, remove the existing toilet.

IMPORTANT!
Due to the powerful performance of our Cyclone, G-Max, E-Max, and Power Gravity flushing systems, they are not specified for back-to-back installations. The only means of installing these toilets in a back-to-back situation is when the toilet drain connections incorporate a WYE fitting. Please contact your builder or contractor prior to this installation.

In order for your new TOTO toilet to fit correctly, check the dimensions below:

1. The distance between the finished wall to the center of the toilet outlet, rough-in “RI”:

Please make sure that you have the correct outlet connection part:

Removing Existing Toilet (if necessary)

1. Turn off the water supply
2. Flush the toilet, and remove any remaining water from the tank and bowl.
3. Disconnect the water connector.
4. Remove the tank and bowl.
5. Remove the old wax seal and mounting bolts.

INSTALLATION PROCEDURE

Install Mounting Bolts

1. Clean any debris out of the closet flange, then install the mounting bolts into the slots of the flange. The bolt should be inserted into the slot with its head down and threaded shank pointed upward (ill. 1). Install Outlet Connection
2. Drill four 11/64″ holes on the floor at the location shown in the Unifit RoughIn installation instructions found in the Rough-In box (see Illustration 2). (5/16″ holes are for concrete/ tile floor anchors).
3. Turn the PVC outlet connection upside down. Firmly press a new wax seal onto the circular recess around the outlet opening. Turn the outlet connection upright and lower it into position over the closet flange. With the unit properly aligned, press down firmly to set the wax seal (see Illustration 3). CAUTION: Do not move the outlet connection after the wax seal is set.
4. Insert the washers and thread nuts onto the mounting bolts and hand-tighten them (see Illustration 4). Then tighten bolts an additional½ turn. Secure the back side of the outlet connection to the floor using the 4 screws and washers. Insert the T-bolts into the slots with the head down and threaded shank pointed upward. NOTE: Do not remove the white tie-wrap from the rubber sleeve. Level the PVC outlet. Do not use excessive force.

Tank to Bowl Mounting

1. Make sure the large tank-to-bowl gasket is mounting over the flush valve outlet on the underside of the tank.
2. Make sure the ball cock nut and flush valve nut are tightened properly.
3. Pick up the tank and carefully guide the flush valve outlet into the bowl inlet on the bowl inlet in bowl tank shelf.
4. Place washers on mounting bolts. Support the tank and align mounting bolts through ½” holes in the tank base and bowl mount shelf.
   Thread on the nuts end, hand tightens before releasing the tank. Tighten nuts evenly until the tank sets snug on the bowl.

NOTE: Do not grab the overflow tube for handling the tank.
Installing Toilet

1. Lift the toilet and gently lower it into position over the closet flange. Make sure that the spigot outlet of the toilet slips into the rubber sleeve and that T-bolts fit through the openings in the base of the toilet.
2. Insert washer and thread nuts on to bolts and hand tighten.
3. Tighten bolts an additional ½ turn.
4. Install cover plates. WARNING: DO NOT over-tighten the nuts, damage to china or plastic parts may result.

Connecting Water Line

1. The supply stop should be installed per the supply stop instruction at the location shown in the Before Installation section.

2. Flush the water line briefly to ensure the removal of debris. Connect the flexible supply hose to the supply stop.
   CAUTION: Hand-tighten only.

3. Open the supply stop, checking for leakage. Slightly re-tighten if necessary. The water supply pressure should be 20 to 80 psi static.

Operation
NOTE: No ballcock/ fill valve adjustments are needed. The water will automatically stop at proper level.

1. Flush the toilet several times. Check the flapper valve for proper operation. Make sure that chain is not tangled and flapper arm is in its proper position.

2. Install the toilet tank lid onto the toilet tank top.

3. Install the toilet seat onto the toilet bowl(see Illustration 7). (Top Mount Bolt Set is included with the bowl). Insert the rubber bushing nuts into the bowl seat holes.
   NOTE: Remove the existing seat if necessary.

4. Place the seat on the bowl and rotate the hinge unit into place while holding seat down on the bowl. Fasten and tighten the bolt from the top with a screwdriver. Replace the bolt cap and the lower lid (if necessary).

MAINTENANCE INSTRUCTIONS

Fill Valve Replacement Procedure

1. Shut off the water supply to the toilet.

2. Flush the toilet and remove the remaining water from the tank with a sponge.

3. Remove the water supply connection at the fill valve.

4. Remove the old fill valve and use a damp sponge to clean the hole in the tank.

5. Place new fill valve inside tank hole.

6. Thread the mounting nut onto the fill valve shank and tighten the nut.
   NOTE: Do not over-tighten. Be sure to install the fill valve in a position that does not interfere with the trip lever operation.

7. Connect the water supply to fill the valve shank and hand-tighten only.
   NOTE: Do not overtighten. These are plastic parts. Never use pipe dope on any water supply connection.

8. Attach the refill tube to fill the valve nipple and clip another end of the refill tube to the overflow pipe.

9. Turn the water supply ON and check for leaks outside the tank.
   NOTE: As water fills the tank, water is also directed into the overflow tube via the refill tube. This additional flow of water is critical to refilling your toilet bowl. Once the water stops filling the tank, some residual drops of water may drip from the fill valve. This is NORMAL as these drops will subside.

Water Level Adjustment
Depending on the manufacturing plant, you may have one of the following fill valves:

For Type A and C Fill Valve:
Refer to the water level (WL) setting marked on the inner wall of the tank. Allow the water to fill the tank. Turn the adjustment screw clockwise in the (+) direction to increase the water level height (see Illustration 1 ). Turn the adjustment screw counter-clockwise in the (-) direction to decrease the water level height. Flush the toilet to verify the correct water level. Adjust as necessary. For Type B Fill Valve:
There are no water level adjustments. The fill valve has been preset at the factory.
*Servicing the Flush Valve (ST453 Model Tank Only)**

1. Turn off the water supply and flush the toilet.
   Remove the remaining water from the tank with a sponge.

2. Remove the tank lid and place it upside down on a clean surface.

3. Pull the dip on top of the trip lever gearbox as shown.

4. Pull the gearbox away and set it on the side as shown. (see III. 1 & III. 2)

5. Rotate and pull up on the flush tower to remove it (see III. 3).

6. Remove the grey rubber seal gasket and rinse under running water to clean (see III. 4).

7. Place the gasket back on the flush tower.

8. Align and place the flush tower into the housing and gently press to snap and lock in place.

9. Replace the trip lever gearbox and push down on the lever to lock it in place.

10. Carefully install the tank lid back on the tank.

11. Flush the toilet several times making sure the trip lever operates normally.

12. Check the water level in the tank and inspect for signs of any leakage.

Replacing the Drain Valve

1. Shut off the water supply.

2. Flush the toilet to remove the water inside the tank.

3. Remove the tank lid and place it somewhere safe.
   NOTE: Before removing anything from the tank, note the placement of the drain valve, chain, and refill tube.

4. Unhook the refill tube from the overflow tube of the drain valve.

5. Unhook the chain from the trip lever.

6. Uninstall the tank (refer to the toilet installation manual).

7. Remove the drain valve body from the tank.

8. Replace the drain valve in the same position as the former drain valve.

9. Hand-tighten the mounting nut of the drain valve and use a wrench to tighten another 3/4 turn.

10. Reinstall the tank onto the bowl and place the chain and refill tube the same way as it was for the former drain valve.

11. Turn the water supply back.

12. Check for any leakage after the tank has been filled.
