BEFORE INSTALLATION

 Read these instructions thoroughly before beginning work.  Please leave these instructions for customers. These instructions contain mainte-

nance and warranty information.

 If necessary, remove the existing toilet.

ENGLISH

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.

Double Combination WYE / 1/8 Bend

YES

Double Sanitary Tee / Sanitary Cross

In order for your new TOTO® toilet to ﬁt correctly, the distance between the ﬁnished wall to the center of the closet ﬂange must be at least 12 inches. This measurement is called the Rough-In.

INSTALLATION PROCEDURE

1. Clean any debris out of the closet ﬂange and then install new mounting bolts (not supplied) into the slots of the closet ﬂange (see Ill. 1). The head of the bolt should be inserted into the slot with its threads facing upward.

2. Carefully turn the toilet upside down onto some padding. Firmly press a new bowl wax ring (not supplied) onto the circular recess around the toilet bowl’s horn (see Ill. 2). Turn the toilet upright and gently lower into position over the closet ﬂange. With toilet properly aligned, press ﬁrmly on both sides of toilet rim to set the bowl wax ring.

C AUTION: Do not move the bowl after the bowl wax ring is set. Thread nuts and tighten evenly until bowl is snug to closet ﬂange. Install the bolt caps.

C AUTION: Do not over-tighten the nuts as damage to the china bowl may result.

Installation Procedure (continued)

N OTE: The toilet bowl has three points of contact, which will actually contact the bottom of the toilet tank when properly installed. The location of these points can be seen on the bowl at the tank receiving area. The three points are front left (1), front right (2), and back center (3). Recall these three points during the Toilet Tank installation.

3. Place the tank upside down onto some padding. Inspect the smaller ﬁll valve nut and larger ﬂush valve nut for a secure connection.

Try to tighten the nuts with your hands

see Ill. 3). 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 valve nut.

Place the tank-to-bowl gasket onto the

ﬂush valve nut. 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.

4. Lay the tank down on its back. Place a rubber washer onto a brass bolt. Reach inside the tank and position the bolt through one of the holes in the bottom of the tank (see Ill. 4).

On the outside of the tank, place a metal

washer and nut onto the bolt. Hold the bolt centered in the hole and tighten the nut ﬁnger tight. Turn the nut an additional 1/2 turn with a wrench. Repeat this process for the remaining hole in the tank.

5. Pick up the tank and carefully guide the brass bolts to align the tank with the bowl. Attach a metal washer and nut to each bolt. Tighten the nuts ﬁnger tight and inspect that the tank is level (see Ill.

5). Once level, tighten the bolts equally until the tank makes THREE POINTS OF CONTACT with the bowl.

Installation Procedure (continued)

6. Flush the water supply line for a few seconds to remove any debris that may enter the new ﬁll valve. (For new home constructions and/or additions, ﬂush the water supply line for more than a minute to help remove any residual PVC adhesives, solder ﬂux, and/or

ENGLISH

pipe sealants that were used for the new plumbing.)

Connect the water supply line to the ﬁll valve threads

as seen at the bottom of toilet tank (see Ill. 5). Tighten this connection ﬁnger tight and then an additional 1/4 turn by hand. AVOID using a wrench to tighten the connection as you may damage the plastic threads and/or cause the ﬁll valve to rotate inside the tank. Water Supply Line Pressure should be 20 to 80 psi Static.

N OTE: NO BALLCOCK / FILL VALVE ADJUSTMENTS NEEDED. Water will automatically

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

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

8. Install the toilet seat onto the toilet bowl using the mounting hardware in the toilet seat box (see Ill. 6). Place seat onto bowl and rotate the hinge down. Position seat stoppers under the seat hinge.

Insert bolt into seat hinge and through the

toilet bowl. Install plastic nut onto bolt from underneath. Tighten the bolt securely. Install the seat bolt caps.

N OTE: Tighten the seat bolt until the hinge is secure. The seat and lid will have slight

side to side movement which is normal. This freedom of movement allows the seat to SoftClose® without binding.

ADJUSTING THE PUSH BUTTON RODS

CST405MF & CST406MF

After making sure the push buttons are installed correctly (see Ill. 8), place the lid on the tank. If the button(s) is too low (see Ill. 9):

1. Loosen the lock nut/s counterclockwise.

2. Turn the rod(s) counterclockwise to lengthen (each full turn is 1mm).

3. Place the lid on the tank to check the buttons. If rod(s) is too long, water will keep running in the toilet.

1. Loosen the lock nut(s) counterclockwise.

2. Turn the rod(s) clockwise to shorten them.

Installation Procedure (continued)

Adjust the rods as necessary by turning the rod 1 full turn (see Ill. 11); to lengthen, turn the rod counterclockwise; to shorten, turn the rod clockwise. When the adjustment is completed, tighten the lock nut to secure it (see Ill. 10).

After Installation/Adjustment

Flush the toilet two to three times to conﬁrm there is no water leakage and that the push mechanism is working properly.

Replacement Procedure

N OTE: The ﬁll valve height has been preset at the factory and DOES NOT require any height adjustments.

1. Shut off the water supply to the toilet.

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

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

Replacement Procedure (continued)

WATER LEVEL

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

5. Place new ﬁll valve inside tank hole.

6. Thread mounting nut onto ﬁll valve shank and tighten the nut. N OTE: Do not over-tighten. Be sure to install ﬁll valve in a position that does not

ENGLISH

interfere with the trip lever operation.

7. Connect water supply to ﬁll valve shank and hand-tighten only. NO TE: Do not overtighten. These are plastic parts. Never use pipe dope on any water supply connection.

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

9. Turn water supply ON and check for leaks outside the tank.

NO TE: 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’s 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

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.

WARNING! Do not over-tighten.

4. Connect the water supply (see Ill. 1 or Ill. 2). Pipe dope is not recommended. Attach the reﬁll tube to the valve and clip the other end to the overﬂow pipe.

Water Level Adjustment

1. Remove the tamper proof key (see Ill. 3) and turn the upper half of the valve counter-clockwise to unlock it (see Ill. 4). Pull up the valve and set it to the desired water level, then turn it clockwise until the valve snaps into the locked position.

2. Turn on the water supply.

NOTE: The tamper proof key is optional and may be used to prevent further adjustment.
